Fontainebleau walks

In the Fontainebleau gardens it is easy to reach your daily walking goals of 7000 a 10000 steps/day. Upon entry into the park you walk around the small lake. Towards the far end of the lake you’ll discover a long waterway which takes you beyond your usual walking distance due to the calm and great surroundings. The forests around the Fontainebleau gardens are another great walking or hiking exercise. You might find companions all along the trails. Just take enough water and food with you as there are no shops around, just you and nature. A bit of advance planning is necessary to make it a great experience.

Air pollution dementia

A comprehensive review and update of evidence that indicates a link between air pollution and dementia has been published in “The Lancet” open access on 2025-7-25. Besides a genetic predisposition the environmental impact of our worsening air quality caused by fine dust particles and PM 2,5 and nitrogen dioxide NO2 has been found in several studies. This updated meta study should be an additional warning to take efforts to clean up our air more seriously. The diesel engines amongst other sources of air pollution have contributed a great deal to this evolution. Inner city inhabitants are at greater risks to suffer the consequences as they are more exposed to these pollutants and for longer durations. Clean air is a matter of brain health in advanced age and biodiversity as well.

Genetic diversity

Part of genetic diversity is the apparent fact that some partnerships have only girls or only women as descendants. This is the message of a study published in Science Advances by Wang et al. on 2025-7-18. The commonly assumed binomial distribution where each event has an equal chance of occurrence at each new point in time does not necessarily hold for this particular events. Therefore, the search for a genetic explanation has been going on for some years. Therefore, there might be a potential for an epigenetic explanation as well, as environmental conditions might co-determine the expression of genes in both parents. The research will surely continue and the sex and gender diversity offers still a lot of surprises. A sociologist’s perspective would tend to focus on later gender attributes and choices rather than sex at birth. The bio-psycho-social research agenda remains wide open.

Just walk

The benefits of walking for several health outcomes is well known. The evidence is in favor of 7000 steps per day as a reasonable baseline. Some outcomes improve further if we walk even more steps, but not all. Probably, the effects of being accompanied while walking will enhance outcomes as well. Every summer the step threshold may be pushed a little bit further. Goal setting can help along to overcome eventual barriers to leave the home later in the evening. Nature rewards us with changing daylight and seasonal changes. We just have to get started to reap those health benefits.

Scienceploitation

Science can be exploited to make unjustified profits from referring incorrectly to it. Social sciences, like economics may be used by banks to sell you products that refer to science only as part of their arguments if the science based inference fits their purpose. Scienceploitation is very common in the field of para-medicine and para-pharmaceutical products. Health promises sell. The time until an ineffective treatment reveals the unrealistic promise to be unachievable considerable profits have accumulated on the side of the selling company. Science has a hard time to counter the perils of scienceploitation. Advanced knowledge can be used and abused as any other method of convincing people to buy or subscribe to a product. The responsibility of the scientific community consists also in finding ever new ways to counter scienceploitation. AI will pose additional challenges as well as opportunities.

Less but better

There are many examples where a new mantra for the 21st century emerges from recent scientific evidence: “Less, but better” (Lbb). In studies of nutrition and human dietary requirements, the importance to eat less has been demonstrated on a regular basis. And this is even more important than to do more exercise if weight loss is the target or the attempt to explain obesity across the globe (McGrosky et al. 2025). The case for eating less is strong. Eating better refers to the need to avoid unhealthy, toxic or cancerous food or the way to prepare food. “Less but better” could become the new mantra or “categorical imperative” if you like it more philosophical in tone. We, the people gain, and the planet will gain as well. It is an easy win-win case, albeit with some behavioral implications.

Pet effects

Pets have effects, some might cancel out each other. In psychology there is a long debate about the pet effect, which claims that pets have overall a positive effect on a person’s well being. This claim has recently been debunked. Many persons have taken over the care of an animal for their own comfort and regular daily routines. The Covid crisis had spurred such behavior in many people, but the scientific evidence taking into account the responsibilities that come with ownership of a pet, can outweigh the benefits of having company. The choice of a pet should certainly not be an easy or haphazard one. There is a need to consider the full range of pleasure and responsibilities. Traveling with pets and vacation times pose additional challenges that can cause stress to owners as well. Dog sitting or pet sitting platforms have been thriving since the Covid pandemic and this is to the benefit of everyone involved.

AI Workday

Our workdays have seen considerable changes throughout the last few days. The home office boom has allowed employees to work for extended hours from home. The there is an abundant literature on the effects of home office work on well-being or the work-life balance. Productivity gains could be reaped by employers and a better work-life balance was a lasting advantage for employees.
The increased use of AI specific to some occupations has introduced a new form of added  productivity for some occupations or professions, AI as complementarity, whereas other occupations suffered a higher risk of being substituted by AI applications.
Based on time diary data, the study by Wei Jiang et al. (2025) reports that users of AI have longer work time and reduced leisure time. Competitive labor markets increase the pressure to put in even higher hours of work. Nerds, just like workaholics, are likely to be drawn into excessive hours of work with increased health risks. Enterprises and consumers appear to be gaining more than the employees, who are at a higher risk of loosing out on their work-life balance over time.

Citizen Walk

Capitals like Paris and Berlin make great efforts to improve the walkability of their cities. After decades of focus on automotive traffic and mobility and the detrimental effects on health for several generations of people, the awareness that walking citizens are part of the solution is spreading. Citizens of Paris voted in a referendum to stop circulation of cars in 500 more streets. In Berlin pedestrians unite to mobilize more people to take to the streets as well and reclaim walking space. In high density spaces like metropolitan areas it is possible to reach all major amenities within a reasonable walking distance. The more spread out suburban area, however, leve fewer options to walk and carry your shopping or do your dily commute to work while walking. Fewer cars and pharmaceutical products sold would mean less „artificial economic growth, but more healthy and happy citizens. It will take decades again to realize such visions.

Killing fields

According to “Le Monde” dated 2025-5-26 the persons who died in the war initiated by Putin amount after 3 years to 250.000. The numb of injured soldiers would be 3-4 times as high. The loss of lives and tarnished life expectancy of persons involved in combat adds up to a huge loss for the Russian people. Being misled by political and military leaders, apparently substantial numbers of recruits for all sorts of services face the choice between the combat field or desertation. Tough choices which remind us of the moral conflict raised already during peace times if you were refusing to join the compulsory military service. Western people are better prepared for such moral dilemmas than the glorification of war in the Russian society. Of course, certainly in Germany we are thankful for the hardships the Russian army and people had to endure during the 2WW. Liberation Day would not have happened without the Soviets, Russia and Ukraine plus many other nations fighting until Nazi- Germany surrendered. The positional battles of the Great War seem to be back again enhanced with a war of drones. The killing fields for a generation of Russian troops is completely self inflicted. How many thousands Putin needs to acknowledge this cruelty? (Image exhibition by Yoko Ono Berlin Gropiusbau 2025-5).

Maison de santé 1861 Berlin

In the middle of the 19th century Berlin was a small city. The area of Schöneberg (pritty hill) was still perceived as the rural outskirts and featured the first botanical garden next to the town center. A little bit more outside of Berlin the “Maison de santé” was founded as early as 1861 to cure mainly respiratory diseases and what later became the first private clinic proposing a new way to treat psychiatric disorders. Dr. Eduard Levinstein was the founder and the clinic had continued its operations for almost 50 years with his wife and sons taking the lead later on. Prof. Wilhelm Griesinger, known for the scientific approach of psychiatry was a proponent of the non-restrained approach to psychiatric disorders, which allowed persons move more freely while being supervised. The documents and the publication (1877) shown in the exhibition at Museum Schōneberg demonstrate the scientific approach to the treatment of addictions, most notably morphine, which had been widely used during the war of 1870 as tranquilizer and pain relief. The wave of addictions needed hospitals and clinics to treat these addictions. The “Maison de santé” had been established as a retreat and cure for other addictions as well. The memory of the early scientific approaches is an inspiring place and reminder to take care of all forms of addiction. Taking care of body and mind is still the state of the art approach today.

The Exhibition catalog is forthcoming, but the visits and material on display of interest beyond the inhabitants of the „Pritty Hill“. Exhibition catalog is forthcoming

Archi health

The links between architecture and human health are manifold. There are direct effects of healthy versus unhealthy materials in construction. For the purpose of making buildings fire proof or more resistant to heat asbestos had been used for decades which still causes health hazards nowadays in the removal of this cancerous material. Paint has to be chosen wisely as well as isolation materials. Indirect or second round effects of materials have to be considered additionally. Cement in construction uses a lot of energy in its production and has only been recycled since a few years in significant amounts. Room climate or even psychological effects of architecture have been considered to be important more seriously in recent years. A new discipline entitled “neuro-architecture” may be developed soon. Schools, sports facilities, hospitals or community centers benefit from healthy architecture. Cost benefit analyses which take into account long term effects and even recycling of materials shift the balance much in favor of health considerations also in architecture. “Fast and dirty” will be much more expensive than “slow and healthy”. Future generations will be thankful. (Image: Spreewald Primary school Berlin).

Health Systems

Comparing health systems across the EU can be complex at times. However, there seems to be a consensus that the Irish health system is an oddity within the European health systems. On the one hand Ireland is a rather wealthy country in terms of GDP, but the primary care system excludes a high percentage of people from access to it. The scientific journal “The Lancet Regional Health” published a paper and comment on this rather unique exception to the rule to offer a universal health care system to its citizens. The controversy is about the coverage of costs of a visit to a general practitioner. More and probably earlier visits to a GP reduce the (over)burdening of
hospitals later during the life course. Prevention helps a great deal to lower overall costs of a health system.
The roots of the Irish health system have been built upon “subsidiarity”, which means that the public support system should only step in, if the individuals or families are unable to cover costs by themselves. Poor households had to apply for a card giving them access to medical care free of charge. Building hospitals was the next challenge and local communities managed to raise funds in support of such additional structures. In 2025 it can be very costly to enlarge the coverage to a universal access to primary care and the challenge to attract sufficient numbers of general practitioners is a very European one. In this respect Ireland is just like any other European country again.
The question of how to best achieve a universal health care system remains an important one. Apparently, you can be rather “health poor” in an otherwise “economically rich” country.

Biased Results

The use of statistics in presenting results of research is common practice. Empirical studies are summarized using statistics and statistical methods based on samples of bigger populations are cost efficient. However, care needs to be exercised when interpreting results to guard against inappropriate conclusions derived from biased estimates. Since the topic has been highlighted and methods proposed to handle them, these methods were deemed worthy of a Nobel prize.  The basic problem of a bias due to a selective sample has been demonstrated by Stockwell et al. (2024). The authors investigate the old question, whether a little bit of alcohol consumption (per day) could be beneficial for our health. The statistical issue which needs careful examination is the construction of the control group against which the results are compared. Apparently many studies have biased control groups which included persons in the not drinking control group who had stopped drinking for bad health previously. Compared to those persons with other health conditions those drinking a little bit compared rather well. But of course such individuals should not be present in a control group. Of the control group is biased due to many persons with below average health the groups of interest consuming higher levels of alcohol do not perform so badly. Hence, interpretation of results from medical or social science studies has to consider carefully the actual or potential sources of bias. Not really a new results in statistics, but still not well known or understood by the public at large. Drug consumption as well as studies of this consumption could deserve the same sticker: handle with care.

Intimate change

Society changes and with it so does intimacy. The major changes pass through the behavioral changes of persons and sooner or later the whole society adopts such changes as the new normal. Trends of individualization have moved over centuries as the exhibition in the Museum of decorative art (MAD) in Paris demonstrates. At the same time the changed individual approaches to intimacy have become more widely spread quickly over time. Social media have accelerated such new trends again. Social class is yet another intervening variable in this context which created different speeds of adjustment as well as sustaining differences in kind. 

Religious beliefs and practices have made claims about how individuals should handle intimate relationships and affairs. Legal issues are defined by each society to guide moral practices as well. Hence, the sociology of intimacy is a huge topic and comparing societies an interesting topic. The development of intimacy over a person’s life course, however, is given little attention due to a lack of adequate longitudinal data. From the exhibition we are encouraged to think about the relationship of hygiene and intimacy. Bathrooms accompany us throughout our lives and privacy was originally a bourgeois concept. Over the life course we move from dependency to independence and maybe dependency again in very old age. The images (below) from the MAD exhibition range from basics of bath tubs to a painting of Edgar Degas in the background. Instagramer or YouTuber share lots of images and stylized arrangements of bathrooms on social media. It seems that intimacy is moving further into the public domain.

Law and Witches

Medical and chemical authorities have been questioned for many centuries. As far back as Friedrich Spee (1591-1635) in the early 17th century there were even among the clergy men with enlightened views on what might be helpful ways to assist people on their journey to better health or simply pain relief. This did include many unhelpful or detrimental methods as well. Scientific rigor was not well established at that time, which opened up many doors for alternative diagnosis and treatment. From a historical and sociological perspective the closing procedures of professional organizations are interesting as well as opposition to them. Early moderators between hardliner positions are rare at the times of forceful and fierce competition between opinions and doctrines that characterized medieval history. In the absence of an independent judiciary earlier moderation could be influential in specific instances. A testimony for can be found in a documentation of the biography of Friedrich Spee and the society that promotes the memory of such exemplary behavior.

Law and Legality

Some persons consider themselves to stand above the law or push all interpretations of regulations beyond usual understanding of it. Even after a person has been dealing with pharmaceuticals or drugs used also for doping purposes, the conviction of such a person may take several years if not decades. In France, Mr Bernard Sainz seems to be a good example of such a relentless case of practicing para-medical consultations to assist mainly cyclists in endeavors to win championships or professional status. Le Monde  and Cash investigation have raised awareness of the public for such dubious practices. The “French Federation du cyclisme” and medical doctors association fight a continued legal battle against this persons exercising illegally such doping assistance. 

With apparently 56 legal procedures in connection with this person, the legal system has to bear the majority of costs of such illegal practices.

The reach of such dubious practices might be extended if the systems beyond doping, but for assisted euthanasia cannot be controlled effectively. Hence, the precursor cases of positive stimuli like doping pose similar challenges to the legal system as “negative stimuli” weakening persons as assistance to die. The end of a life course is not only a medical issue. Society-wide debates need to take place in order to organize a large consensus on the implications more liberal practices shall entail.

Suicide Prevention

The annual mortality statistics and special reports on suicidal tendencies are a tough reading. OECD Statistics give a at least an approximate, comparative perspective. Reporting routines and medical confirmation of a suicide or suicidal behavior still vary quite a bit between countries. Nevertheless, the usually reported incidents per 100.000 persons remain rather abstract.
Absolute numbers speak a clear language. For example in Germany there were about 10.300 recorded suicides in 2023, France had to mourn about 9200 in 2022. To put the size of the problem in perspective it is helpful to know that in Germany all other not aging related causes of death like traffic accidents, drugs or murder make up for around 7.000 deaths per year. The targeting of resources and prevention efforts on these vulnerable people seems inevitable. However, we see only limited additional efforts to curb the problem.
A more detailed analysis of the frequencies reveals the gender and age differences. More men commit suicides and older (very old) people have higher risks. The oldest age group of men is most at risk.
Since the Covid-19 pandemic young women show rising trends in many countries again of suicidal attempts and self-inflicted wounds. Despite a continuing effort of research (Links) there is no single cause to explain the occurrences.
As a working hypothesis, which awaits empirical tests, I would look into societal factors that stigmatize persons who are made to believe or feel like they are beyond the normal spectrum of society. The lack of acceptance of diversity concerning gender, age, ethnicity, body shapes or mental states like anxiety. Poverty might cause immense distress and suffering. Large shifts in wealth in both directions cause additional risks.
It seems as if our minds and society are constantly in a kind of „regression towards the mean“ posing challenges to those furthest away from the average or perceived norms. Percentile ranks or percentile scores are commonly used to express a person’s position in a frequency distribution. For example you are better/lower than 90% of persons of your age group. Such statements might cause further distress for persons. However, summarising across several (psychological) measurements, they may yield encouraging indications as well. Actual and perceived positions in such percentile ranks add another “social risk” as perceived positions may govern behavior.

Defence Spending

As in research there are many dual use products, which can be part of defence spending. Robotics in production or rockets to launch satellites for telecommunication are such examples. Much less known to the public is the amount of military spending that goes into medical developments that benefit both the military as well as the civil population. Countries build a whole ecosystem round the provision of medical services for defence purposes , which consists not only of a sufficient number of qualified persons, but also companies that provide specialised products. Most of them have civil applications as well after minor adaptations.
Oxygen provision was a prominent example of a product that has civil and military uses in treatment of respiratory infections or contaminations. A mobile transportable operation table is another element of daily rescue services as well as potential use in situations of conflict, just like anesthesia machines. An increase in spending on such infrastructure and the necessary long-term training of persons operating and maintaining these medical applications take time and considerable financial resources.
The current debate in Europe and NATO neglects the considerable time delays in production and provision of the equipment. Research on “Skill Needs in OECD countries” has shown the substantial delays between sudden skill needs and the time to train high-skilled persons.
The International Review of the Armed forces Medical Services is a journal dedicated to publish up-to-date information on needs of medical products and persons trained to use them in special emergencies. The need to safe lives in extreme and dangerous conditions needs preparation of thousands of specialists. Of course we hope that such an incidence will not happen. The persons and material have an obvious potential to serve the civilian population in more peaceful times as well. The unfortunate “hog cycle” in skill provision is not a problem for dual use products or services.

Obesity Revised

The scientific paper on a revised definition of obesity was produced by the special Commission on Obesity. It appeared in The Lancet Diabetes & Endocrinology in 2025-1. The previously common practice by medical doctors was to classify person in the obesity category based mainly on the simple calculation of the body mass index (BMI = weight/height²). A BMI  > 30 put persons into the obese category and stigma.
Since the Covid-19 society-wide testing experience, we are all familiar what it means if you get misclassified and have to live with the consequences (exclusion from work or events etc.). The simplifying and summarizing BMI calculation and classification has also produced many wrong classifications. For example, persons with a lot of muscles (just watch this at any fitness studio) will have a high weight relative to their body height², but they are likely to be more healthy than many other light weight, but seriously stressed persons.
In empirical test theory such cases are the so-called false positive cases, i.e. classified as obese, but not a medical problem at all. Medical doctors and health insurances should not finance special treatments for these persons, which foregoes treatment of other more needy persons.
With new expensive drugs on the market to treat obesity it is even more important to test with more precision the normal, pre-clinical and clinical status of obesity. Fatty tissue or muscles, that is the relevant question. Fatty tissue in muscles is the next level testing issue.

Investment Disinvestment

Asume we live in a world of fixed amounts of investments. The option to invest in a new project or product will automatically reduce the amount of investment in another product. The investment decision, therefore, is subject to opportunity costs. A recent study by Naci et al. (2025) applies this rationale to the investment in new drugs compared to financing other traditional treatments. The results for the U.K between 2000 and 2020 revealed that the „quality-adjusted life-years (QALYs)“ is not in favor of the investment in new drugs. The relatively small numbers of beneficiaries of the new drugs is compared to the many other persons who could have benefited from the less costly previous treatment. Investment in one new drug causes disinvestment in other ones. The overall balance for the UK turned out to be negative. Particularly the disinvestment in prevention of diseases appears to have very detrimental effects in view of the results based on this study. Preventative measures are relatively cheap compared to the estimated 20.000 pounds for one additional quality adjusted year of life for a new drug. The message is: choose your health investments wisely to avoid ever rising health costs and health insurance. (Image: rest room Belgium)

No tobacco Sweden

Sweden is the forerunner as country with the lowest number of smokers across Europe and probably even the world with only 5% of the population 16 years and older. The success of these public health policies is due to banning smoking not only form pubs and restaurants, but also outside in the surroundings of public spaces like schools, playgrounds, train stations and sports facilities. These policies work quite well and the effects of discouraging smoking in public is reduced to a minimum rather than the normal encounter.
Health of the other persons and children passing through these areas is not the only goal. A new estimate of lost days or years due to smoking based on a study from England shows that “each cigarette smoked reduces the smoker’s life by about 20 minutes (17 for men, 22 for women, LINK to study). Of course, there is a huge variance and other work and life conditions that play an important role as well, but the broad average estimate is a nice way of talking about statistics. The basis of the estimate is for those who stop smoking and not those reducing their tobacco intake by some percentage or replacement product.
In the Belgian football stadium (image below 2024) in Brussels the No tobacco sign is well placed to make parents of children and youth understand the challenge ahead. Good resolutions are assisted by gentle regular reminders as well.

Health Tech

Health technology assessment (HTA) is an interesting scientific field. The new digital opportunities allow people to participate in medical and medication trials in their homes or even in bed. Their health data and the administration of medication is also encouraged and sometimes supported through digital devices. The pharma and health industries have many devices ready to go. The differences to the traditional forms of medical trials, however, is an issue as we want to compare the results from both kinds of trials. Participants of trials, might prefer or struggle with these novel kinds of study designs. In any case the results will be impacted in several forms (Study Link). In the best of all worlds for the researcher the effects will cancel out each other, but is rather unlikely. Some participants will reach more positive effects with the use of digital tools, whereas others are challenged and might even abandon during the trial. Monitoring during the study (for example through digital inhalors) is another advantage of such distributed trials. Rather than taking adherence to a trial medication for granted, digital tools allow a more precise monitoring of subgroups as well. Data and effort invested in the trial is preserved through the easier access to person’s information, assuming continuous readiness to stay on in the trial.
Our own smartphones are still underexploited in terms of health monitoring and use in research designs. The possibilities to link data to other external data sources shall further advance the research potentials in many interesting ways. Data protection and data security become even more important with the ever smarter phones and connected devices.

Health data

2025 will be a crucial year for health data across the EU. Germany introduced the electronic patient card, which can store basic information to then access data in the health insurance cloud for medical doctors, hospitals and other related health services. Potentially this is a great step ahead as some tests do not have to be repeated if they had been completed recently before already.

In pseudomised form, research may draw samples from such databases to enhance our science based understanding of disease. The evaluation of public health interventions becomes easier and medium and long term efficiency of measures can be assessed in many instances.
The Belgian research using health data has met to discuss the potential and limitations to link health data to other data sources to allow more complete and more complex analyses of health and disease processes. Another extensive data source sits on our smartphone. Collection of steps walked, sleep patterns or heart beats give valuable insights into a person’s own contribution and care about personal health. Although data are frequently incomplete, researchers are used to estimate missing data on the basis of existing or comparable person’s data. The basis for improving health for all are quite promising, data handling and linking them will be a challenge to the competence of all stakeholders and everyone involved in better health. It will be stressful before it becomes a routine.

Shorter is better

Contrary to a lot of received previous recommendations, the shorter duration of antibiotics prescription and use (3-5) days is overall better than the prolonged use of durations between 7-14 days (JAMA Link).  A so-called narrative review of medical studies (Lee et al.2023) reports more precise results separate for medical indications (pneumonia, sinusitis etc.), which tend to go in the same direction for the majority of indications. In view of the serious issue of antimicrobial resistance, a consequence of overconsumption and too widespread use of antibiotics (also in animal health and food production), the slogan of shorter is better should receive serious attention.
It is not only a medical, pharmaceutical or public health issue. The topic has become an issue of nutrition as well. The food chain contains largely unknown amounts of antibiotics as well, especially if larger amounts of animal or fish products are part of it.
The knowledge from these sciences has still to filter through to the broader public. This means it has become a social science topic as well. The transmission of knowledge and patient expectations on prescriptions, which is also linked to regulations concerning sick leave, make it more difficult to shorten prescriptions of antibiotics. There is a steep challenge to change behaviour according to the new mantra “shorter is better” with respect to antibiotics, even if we know that it is better for all of us in the medium or long term.

On Intersectionality

Society deals with individualization or individualism in various forms. One way is to take each social group as a specific singular case. This is reasonable and justified in many instances. There are cases where this form of dealing with specific social groups comes to limits. Following the rationale of plurality and individualism it has become common practice to address each target group in a specific manner. Intersectionality, however, acknowledges the overlapping of target groups, which necessitates a more specialized approach to intersecting (social) phenomena. Gender might not be the single most important factor to describe a person, just as age is a concept of various intersections. Chronological age versus age defined through biomarkers demonstrate the variety and potential for intersectionality. The Paralympics 2024 in Paris gave another positive example of intersectionality as extraordinary persons achieved previously unimaginable world records in specicialized disciplines. Individualization and classification is only a first step in the scientific endeavour, the analysis of intersectionality is an additional step to consider in a broad range of fields beyond the social sciences.

Bi-directional Sleep

For most of us bi-directional sleep is a question of sleeping on the left or right side, or on our back or front, head left or right. In immunology bi-directionality of sleep has another meaning. The immune system is linked to sleep in a bi-directional manner. Good sleep enhances the immune response of cells (direction 1) and infected blood cells for example send a signal to the brain to extend sleep. The study by Huynh et al. (2024) in Nature has demonstrated this bi-directional mechanism. It allowed mice who slept well after an imposed heart attack to recover in a better way than those whose sleep got interrupted during the experiment. The most natural response to a heart attack or acute coronary syndrome is more sleep. This is induced by an inflammatory reaction in the brain, which « orders » your body to increase deep sleep. 😴 Sleep is more than just rest, it may be part of healing. ❤️‍🩹 (people looking at Caspar David Friedrich „Infinite Landscapes“, exhibition Alte Nationalgalerie Berlin 2024)

Water Quality

Obviously, water is not just an issue of quantity, but also quality. The availability of sufficient quantities of water in a region depends on rain, its storage, and the use of these water resources. The quality of water is a subsidiary issue, as lack of inflow causes concentrations of nuisance in water to rise. Global warming will most likely intensity the concern for not only the quantity, but also the quality of water.
Public services are in charge to sample and monitor levels of water quality for consumers. Independent of public, private or public private partnerships in this field there is a need to check from time to time the quality of water. Public institutions do a great job in monitoring water quality, but as science progresses there are new sources of pollution that enter the already complex analysis of water quality. New chemicals and remains of medical or pharmaceutical analyses have been retrieved from water and, sometimes, they have reached critical or unhealthy levels.
More detailed monitoring is necessary and new digital tools allow to improve just this type of monitoring to inform policy makers on shifting patterns.
A project of that type “Urban Green Eye”, for example, allows to monitor the artificialization of previous vegetation to show up on satellite images of Germany. Independent groups, citizens or communities might find it useful to use their own sampling and testing to guard against abuses or dysfunctional public monitoring systems. Start-ups like “Hydroguard” offer services to support activists, communities or public services in their own efforts to ensure water quality.

Public health info

Public services have a premordial role to play in providing reliable and up-to-date information on health issues. It is no longer only in charge of collecting this information, for example on infectious diseases, but public services are in charge of timely disemination of that info as well. This is, of course, were online services and AI come into play. Getting out this info is crucial, but in the age of fake news and the wide disemination of news on social media, public services need to check also what becomes of the news they have published. The Covid-19 pandemic has been a worthwhile experience in this respect. It is important that reliable information is transmitted via trustworthy channels, which have already been established prior to the “next” health crisis. Many innovative tools were presented at the SCCON 2024 and maybe trustworthy video calls with a medical doctor or your pharmacist may constitute a solution to many infectious pandemics. However, trust in the technology is important as well as equipment and identification systems to be sure that your medical doctor you meet online is actually a medical doctor or only a savy pretender. The issue is as old as medical assistance. The RKI in Germany is the reference information for coordinated information on many public health issues like infectious diseases.

Science Fraud

It is a big issue if publications in science in high reputation journals have managed to pass a rather lengthy and thorough peer review process and still contain evidence based on fraudulent data. The worst case scenario that based on this wrong evidence tests of useless drugs are performed on patients in hope of an honest concern for their health. In fact the financial rewards and even academic rewards have been achieved only through the successful publication of a bias introduced into the data and/or analyses of the data. The fraudulent researcher became subsequently Director of the institute of agingwhoch is part of the American National Institute of Health (NIH) and an academic reference in health sciences far beyond the USA. It is the merit of Charles Piller and his team to persist in challenging the treatment recommendations which were concerning Alzheimer and Parkinson diseases. The checks and balances in the academic research have failed and a serious reconsideration of the procedures should follow, not just business as usual.
