Dry January

There is a health trend to pass a sober, “dry January” after the X-mas and New Year festivities. It seems to be rather popular, so that the French wineries have started a marketing campaign of a “French January“. We shall see what the battle of marketing campaigns means in the end for the health of our liver (Study Link). It might lead to changes in consumer behavior of the following kind. Take advantage of good price offers for French wine and champagne in January and drink it as of February.
For addicts of the “carneval season” this should not be too difficult, jointly with a couple of friends. Alternatively, you might not be bothered and continue a moderate consumption across seasons. Moderate consumption, however, is the tricky part of alcohol consumption. Medical guidelines (health of liver) have evolved recently to count each drop of alcohol into your total consumption in either fluid litres of pure alcohol or the equivalent measured in grams. 

Mammalian Aging

Mammals share a lot of similarities with respect to aging. The researchers Alexander Tyshkovskiy and Vadim N. Gladyshev et al. (2026) spearheaded multiple research to identify similarities across humans, macaques, rodents and mice. The outcome of this overarching study of mammalian aging and mortality is a set of biomarkers that can serve to predict time to death.
Why is this interesting? With the rise of the longevity interest in the 21st century, the need increases to use robust biomarkers that can assess any presumably miraculous innovation to smooth human aging or prolong the time to death. Steps towards “universal transcriptomic signatures” including CDKN1A and LGALS3 (compare across species), which proved to be important in mortality predictions based on the large UK Biodata.
It is the accumulation of damage, which drives  processes of aging . However, “inflammation, replicative senescence, metabolic inhibition and γ-irradiation” can be attenuated or occasionally even reversed. The aging of cellular components has been demonstrated using “modular-specific clocks”.
With these biological advances in the field of biomarkers, the BPS nexus (biology-psychology-society links) could receive more attention as well in order to enlarge the society-wide research into the causes of human aging.

Gone paddling

Similar to windsurfing, paddling has not only a physiological, but also an ecological impact. Rather than using external power the equipment requires a good sense of balance on the board and propulsion originates in your own muscles. The benefits are great for mind and body and sharing a board is the standard way of getting your regular exercise.
There are more and more stations near the sea or on lakes available in 2026-5, so that it has become a much more accessible form of exercise. Paddling is also an age-inclusive practice, since the “probability to fail“, with the pleasure of spontaneous diving, is spread relatively equal across ages. Learning curves, however, may differ substantially across generations depending on prior balancing experiences. The ecological bottleneck consists in the access to sufficiently clean water resources so that the healthy and fun exercise shall have positive long-term health effects

Gone walking

During busy weeks or travel times it can be difficult to keep your average healthy walking distance up to standards. Rather than traveling even longer distances to far away destinations, nearby areas might have to offer lots of options to get more exercise of any kind and particularly walking. The environment for walking plays an important role as well as for example walking on the beach distracts easily from the efforts involved. You don’t have to go fishing, but lots of activities will encourage you to further to explore soft forms of exercise. 

Family Archaeology

The archaeology of family bonds is an interesting branch of both archaeology and genealogy. The mixing of hunter-gather populations with settled populations seems a rather ancient fact (study link). Analytical DNA comparisons reveal that nearby groups had indeed contact and even intermarriage occurred more than 5.000 years ago (Mattila et al. 2026). The evidence is based on data from a cemetery where several persons were buried in the same grave.
The study by Blöcher et al. (2026) demonstrates that in the late phases of the Roman empire along the Roman frontier in Germany a mixing of Romans with local populations a similar process took place. Whereas genetic structures persisted until the 6th century, the Central European genome as we know it today refers back to the 7th century. The inter-generational transmission seems to be an important driver of diversity. The high infant mortality together with an earlier mortality of women than men at that time show the accomplishments of modern medicine to safe infants and mothers from the hazards surrounding family formation and survival.

Dementia Prevention

The United Nations reports on countries’ activities like dementia prevention plans. Focus is on the medical sociological analysis in which dementia is not only determined by a person’s individual life course, but it is also a society-level issue. Looking at dementia prevalence and incidence over time as well as major known risk factors, Mukadam et al. (2024) conclude that low education level, smoking, obesity, hypertension and diabetes all contribute substantially to the risk of dementia. The trick with education is simple. If you start on a dementia trajectory from a high level of education, it will take longer until you are fully dependent on other persons. For the other causes there intrinsic or genetic components, but a large share of dementia risks can be reduced through behavioral changes early in life. My all time and all ages favorite is walk whenever and as long as you can.

Time Response

Time enters in many studies of behavior as response time. It could be summerized under a mechanism defined as “action – reaction” in many instances. In the animal model this is studied not only from external stimuli and bodily reactions, but with direct brain or nerve stimulation and subsequent reactions in other parts of the body.
Within humans the same rationale is widely acknowledged as well (Kimura2023). In many processes it is not no longer a question, whether a response will occur, but the differences in response time play a crucial role, for example in processes of aging. In many mental processes, response time is a fairly reliable indicator of aging as response time increases and the reaction is slowed down. The focus then shifts on strategies how to keep response times within usual boundaries. Eliminating or at least reducing disturbing peripheral influences like noise or light as distractions become an issue. In jazz music, the “call – response” mechanism has entered as a successful element in composition and improvisation. Time and response or response time is a highly passionate, physiologic and emotional issue.

Dual Task Processing

Extensive research into dual task performance shows that training of 2 tasks simultaneously can indeed enhance performance. New research by Schubert et al. (2025) indicates that there latent and persistent bottlenecks to the brain’s processing of such dual tasks, let alone multi-tasking. Out of own anecdotal exercise with “object tracking and touch” (gaming on tablet) a learning effect arises. However, it is unclear, whether this exercise translates to normal traffic situations in inner city situations for pedestrians or cyclists. The experiment of a dual task, combining a visual-manual and an auditory-verbal task, indicates also training effects, but the brain appears to return to sequential processing rather than simultaneous processing as much as it can. Such a dual task test may consist in juggling while singing a song or even leading a conversation with somebody. Quite a challenge or exhausting mental training even for those with a history of juggling objects.

Bob the AI-enhanced builder

Most kids today and GenZ youth have come across the TV-series “Bob the builder”. Baby boomer parents have been worried about the work ethos which might be the hidden agenda of the videos. In 2026 we can now draft a new episode called “Bob the AI-builder”. Many episodes could be re-written when Bob and his team have access and get training with AI toolboxes. The study published by ActivTrak (2026-3-11) reports that companies make on average use of 7+ different AI-tools, up from 2 in 2023. This constitutes a hint that complexity at work is increasing as each tool has to be managed and the boundaries of its use need to be respected. As most search engines offer an AI-short cut to search it is not surprising that now 80% of the workforce use some form of AI in 2026. The productivity increases in quantitative terms as more output can be achieved in the same time or slightly shorter work days. However, workload is moved even more to weekends now.
The upcoming challenge through AI-tools is the reduced “the AI users’ focus time”, which suffered 9% compared to non-users. For Bob the AI-enhanced builder this means “AI is being used as an additional productivity layer, not a substitute for existing work”. The overall workload is not reduced by AI. The intensity of work increased between 2023-2025.
There is still a puzzle in the data. Multitasking (+12%) and collaboration (+34%) both increased, but the duration of an average focused session and focus efficiency dropped. The challenges for employees increase. Handling simultaneous processes and keeping an open mind to collaboration are key competences for Bob the AI-enhanced builder.

Holistic public health

Based on case study in Queensland Australia, Boocock et al. (2026) propose the wider application of holistic public health laws. Due to effects of global warming the local burden of disease may rise due to larger scale floods and subsequent growth of for example mosquito populations that transmit infectious diseases. It will be necessary for societies to understand the processes behind the growth of mosquito populations and what can be done to prevent and protect oneself from the consequences. This is not only an environmental issue, but also an issue of continuous learning across all strata of society. Neighborhoods tend to suffer the same impact of chemicals used or the spreading of diseases like Dengue or malaria. The case study makes a convincing argument about the intrinsic relationship between the social and environmental processes at work. 

Exercise and neurons

The neurons in the brain have an active part even in training effects of physical exercise. Morgan Kindel et al. (2026) have accomplished a rigorous test that demonstrates the involvement of brain neurons when mice were exercising repeatedly. Training effects were larger if the neurons of brain cells were involved as well. The cell’s learning ability encodes the experience of exercise and is prepared for a repetition of the exercise. This is roughly what happened in their experiments in my own words. Runners might know the effect that running on track or treadmill uses up less calories than running cross-country where the brain is more challenged to avoid missteps or loss of orientation. However, the latter are different tasks whereas the former experiments demonstrate that the brain is involved in physical exercise even if we do not notice it. Exercise might spur brain plasticity just by doing it. Hence, just do it.  

Time to prevent

If we take a medical life course perspective, we shall become aware that for each event there shall be a time to prevent it. From a scientific and socio-economic point of view, this is the crucial time to prevent failure of an organ, duration of an illness, death or an otherwise disruptive event. Taking our lung or liver as examples we intuitively know that there is a long time spell during which we have a chance to work on prevention. The monitoring of the early onset of disease is (Ge et al. 2026), potentially, a very cost-saving way as well in addition to avoid humans suffering later on in multiple ways. From a theoretical point of view it will be interesting to “think intervention as prevention” already, rather than the predominant way of intervention “post-hoc”, which means after the onset of disease. This implies a rather complete overhaul of medical research just as much as social research to guide policy makers interested in the “survival” of our social security systems as we know them currently in Europe.

Medical Life Course

The analyses of the life course have taken individuals as their starting point and linked their life courses to broader societal developments like periods of educational expansion, job growths or periods of high unemployment. Medical life course research has further dis-aggregated the life course of a person into, for example, the life course of human organs.
There is already an established line of research which collects and analyses lung function trajectories. The research starts even before your first “autonomous” breath and typically ends at death, although transplants become feasible. It is helpful to think of those measures lung function trajectories as a life course of lung health, because the air we breathe is subject to many social and environmental impacts. Some we are in control of (active smoking, less so with passive smoking), some others like inner city smog or pesticides inhaled in areas of agricultural production. Work environments play an important role in the life course of the lung as well. Global warming, particularly increases in summer heat, pose additional challenges on the overall aggregate level to lung health trajectories.
Inhale, exhale, … then force your breath out quickly, … keep breathing normally. That’s about the instruction for the “Forced Vital Capacity test”, which is a standard measure of your FVC just repeated over the life course.

Illness duration

The focus in medical analyses is primarily put on the diagnosis of illness. This is the best strategy, if the onset of an illness has a precise beginning and ending. In all processes, where either the beginning and/or the ending is less well-defined as precise point in time, the progression, as phase in or phase out of illness, is also of substantive interest. A duration analysis can inform about the potential presence of a co-morbidity in case, for example, an infection continues beyond the normally expected duration.
Financial pressures in the medical systems makes it necessary to release patients in a timely fashion. Therefore, has become more important to monitor patients even after release from hospital. Digital devices can support such a monitoring.
The study by Josi Levi and co-authors (2026) shows that smartphones or just the monitoring of the number of steps of patient offers a rather reliable indicator on the health status towards the end. The information that a patient has recovered to the normal level of activities as before the onset of the illness works quite well as indicator of recovery. A more precise measure of the duration of an illness is important for patients, care persons, the health system overall. The duration is one of the cost-intensive factors of any illness and it is surprising how little we know about the issue of time and duration in many health processes.

Regulation and bureaucracy

Economists will celebrate 55 years of the theory of regulation pioneered by George Stigler, which was published in 1971 in 2026. The basic question asked at the time and today is: why do we have regulation? The pubic choice and political economy answer of Stigler (1971) and many scholars after him, is that the industry of a specific sector will acquire the regulation or the public interest in this regulation and, subsequently, the industry will design and operate it to its benefits. At least, this is in a nutshell my summary of the literature inspired by Sam Peltzman (2021, p.20). If we add to this the perspectives of theories of bureaucracy (Sharma, 2020), we become skeptic of an efficient implementation of regulations by governments or governmental agencies.
In the field of pharmaceutical applications, it is the “European Diabetes Forum” which calls for a regulation on reliable “glucose monitoring devices” with industry and user backing. Of course, this asks for bureaucratic control of the regulation, imports and markets of such devices later on. The one (regulation) is rarely coming without the other (bureaucracy). It is about time to acknowledge this for societies as a whole as well.

Time and power

Who commands our time? Who commands your time? Both macro- and micro-level analyses of power relationships related to time need to be investigated. Time policies are most obvious when it comes to regulations of working time, permissions of business hours or so-called bank holidays. On the micro or individual level, it is often the question of who spends more time on work, care and repair. Hourly wage rates have been claimed by economists to guide or decide societal time spent on one or the other activity. An extension of this rationale with an overriding objective of happiness might considerably change the impact of power relationships on time. Longer time perspectives on health shall also shift the view of how power impacts the time spent on various activities. Time sovereignty is a precious value in its own right.
The power play between employers and employees keeps shifting the balance, albeit the overall trend over the last 100 years has been towards a reduction of working time and increased time sovereignty of employees as a form of democratization of working life. This constitutes one form to share the benefits of productivity gains over decades as well. (Image clock on Berlin City Council building on labor day 2025).

 

Multiple clocks

There is nothing more confusing that multiple clocks that are ticking away without being synchronized, which means, they ought to show the same time. A medical and social science perspective on multiple clocks, however, builds on the fact the different social processes run with different speed, i.e. multiple clocks are ticking in parallel but one may be more advanced than the other. The study of longevity has recently acknowledged that each human organ is aging at its own speed and if the time to failure is close for the liver, the time until problems of your heart might still be far off. Overall longevity is determined by the time to failure of a major organ, despite the fact that multiple clocks of organs are running in parallel.
The can be observed for social processes where, for example, the timing of unemployment or retirement might be dependent on a parallel process of a household dissolution causing a peak in stress. Overall life satisfaction, therefore, depends largely on multiple clocks that might be running in a synchronized or not-synchronized manner. Hence, we all live with multiple clocks ticking inside us and around us. The illusion is, to believe that time is just a single, unique measure.

Premium for silence

People are willing to pay a premium on housing prices for a more silent environment. In the study Enrico Moretti & Harrison Wheeler (2025) estimate that the construction of a silencing wall near a noisy traffic junction or road will increase prices for every decibel of noise reduction by about 3%. Distances closer to the noise shields get higher increases and this mechanism works even up to 400 meters away from the isolation. The investment in decibel noise reductions (not statistical noise) meets a willingness to pay a premium on housing prices. Investment in positive environmental effects (silence) have an obvious marketable premium value. This is most likely just the obverse effect that noise nearby housing is penalized and part of the social mechanism of gentrification. Housing prices and rental costs are known to be powerful drivers of gentrification as well.

Metabolic harm

At the beginning of the 21st century the lack of physical activity for large parts of society has become a major risk of and cause of metabolic harm. We have become used to a sedentary lifestyle and the digital access to distractions and information have encouraged further immobility. Alex Broom et al. (2025) stress the importance to include social and governmental interventions into the many existing medical, pharmacological and technological interventions. The authors advocate a rather holistic approach to really make a difference. The obesity trends cause metabolic harm of an  unprecedented size. We have to rethink mobility patterns and other behavioral changes into our daily routines to bring back more stimulation to our metabolic system.

Climate & Health

The priorities of reporting in newspapers and in media more broadly neglects the direct links between climate change, global warming and public health. The study by Weathers et al. (2025) has investigated this underreporting of scientific facts between 2012-1-1and 2023-12-31 with regard to China, India and the USA. As these are not only big countries, but also among the heaviest polluters. Public health is in the majority of cases addressed as a general public health issue, Extreme heat (51%) and extreme weather (44%) are mentioned most as single issues followed by poor air quality (35%) and food insecurity (25%). The human species suffers from a severe short sightedness when it comes to the public health issues that will intensify due to global warming. Directly following the destructions, worsening health due to heat and pollution, sometimes both even coinciding, will cause additional medium and long term detrimental effects. Although this is known today, there is still little concern about real policy change. The COP 1-30 has achieved little in this respect. It is questionable, whether this format outside of the regular UN institutions (for example within UNESCO) was and still is the right choice.

Multilingual aging

Some myths, for example about the effects of multilingual competencies on brain health, continue to hunt people. The proponents of a monolingual world are widespread and have in some countries fatal historical heritage. The study by researchers  (Amoruso et al. 2025) use data from 86.000 persons in Europe  (SHARE Database, waves 1-9) from several countries. They show the better aging of brains for bilingual persons and even more so for persons practicing multilingual 2+ languages. The “domain-independent protective effect of multilingualism” for healthy brain aging is very robust and works after statistical accounting for other potentially intervening factors like socioeconomic or institutional factors. Some known stressors like migration, however, which operate often as psychosocial stressor, can have similar negative effects just as alcohol consumption and sleep disruption. Multilingualism and the correlate of multiculturalism keep a brain “on its toes” and contribute significantly to our healthy brains.  

Polypharmacy issues

As we age, we become more likely to confront polypharmacy issues. Polypharmacy is defined as taking 5 or more medications per day. The study reported in The Lancet healthy longevity by Payne et al. 2025 had participants with a median of 4 health conditions and a median of 8 prescriptions. Even a comprehensive set up which involved several experts from medical doctors and pharmacists did not manage to achieve a significant improvement in polypharmacy outcomes in this experimental study with otherwise carefully matched intervention and control group. However, the mental health (measured in patients as “health-care-related quality of life”) slightly increased and the “treatment burden” experienced by patients was slightly reduced.
In combination with a previous study the probability of errors in nurses, who are the prime persons responsible for the administration of medications in institutionalized settings, the reduction of potentials for errors like they are to be found in polypharmacy should continue to be a prime target of this research in future. Together with the knowledge about the prevalence of functional illiteracy at older ages, polypharmacy remains a critical issue on the public health agenda beyond the experimental settings in this study.

Tether thy liver

There are few of us who take our liver seriously. Yet, this big organ plays a central role in our body to regulate metabolism. The obesity pandemic in western countries increases health risks, just as excessive alcohol consumption increases risks of liver dysfunction. Additionally, viruses increase the risk of failure of this organ.
Each of these risks as well as any combination of one of the risks with another one have led to rising public health risks. Several studies since 2020 have highlighted these increased risks for populations in general. The risks, however, have an unequal spread across subgroups of society. A recent comment based on the research of the INSERM U955 team in “The Lancet Regional Health” by Brustia et al. “Liver-related mortality strikes hardest where deprivation is greatest.” Health inequities consist in the lack of income available to buy healthy food or in untreated alcohol addiction, both more common in poor people.
In order to tackle the inequity, the team of medical doctors call for a shift in awareness. Structural reasons like diagnostic delay, remoteness or health literacy are just as important as individual predilections like nutrition or lifestyles. Inequality in access to health and ability to afford a healthy lifestyle have become serious drivers of social inequality in the 21st century.

Unexpected effects

It is, unfortunately, a rare event in science to publish unexpected effects of an experiment. Sometimes, results even turn out to be the opposite of what to tried to show with the use of an experimental setting. The learning for the science community, however, is bigger in such cases. Why? A carefully designed experiment (Oliveira et al. 2025) to measure the effects of 2 different 12 month long yoga trainings to prevent falls in 60+ persons (mean age 67) revealed that the less challenging “seated yoga” was better in preventing seniors from falls.
Participants in the more challenging Iyengar yoga-based sessions reported more falls in the 12 months follow-up period. Due to Covid-19 the trainings took place as an online course, which might have reduced the influence of a coach in correcting positions and observe other physiological or psychological issues with participants.
However, the insights are a great lesson for experiments to produce opposite results of expectations with the lesson that human beings can be rather complex. From a health psychology perspective, it might be the case that participants in the more challenging yoga classed became also more daring in balance as well as other exercises.
Just being overly confident compared to their positive improvements, which might turn around an initially positive effect on balance and falls. From a socio-economic perspective, we would question the implicit assumption of the study that participants have a random distribution or underlying tendency towards risky behaviour. The longer the observation window (post-intervention) is, the more intervening socio-economic factors enter into the physiological-behavioural equation. Hence, expect unexpected effects.

Age of maturity

The bronze statue by Camille Claudel „L‘âge mûr“ is her most famous works. It is part of the exhibition Claudel & Hoetger in the “Alte Nationalgalerie“ in Berlin. Usually the statue is part of the permanent exhibition in the „Musée d‘Orsay“. With the depiction of different stages of the life course and somehow revealing the emotional trajectories of the persons the scene of human joy and tragedy becomes tangible beyond her personal fate. The scenario and arrangement in the Alte Nationalgalerie allows to focus on this particular work with an emphasis on the trajectory and the evolutionary path. A unique arrangement does better justice to the particular message of the artist than being surrounded by too many other works of art. (Image: extract of Camille Claudel‘s „L‘âge mûr“ in showroom Alte Nationalgalerie, 2025-8)

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.

Work time reduction

One of the major elements of social progress in the 20th century consisted in the reduction of work time. Reductions from 48 hours per week in the first half of the century were largely reduced to 40 hours per week or less in some industries with strong trade union representation. State regulations also pushed in this direction with positive implications for physical and mental health as well as wellbeing. Advances in longevity of employees may be attributable to this social progress agenda of the 20th century. In the 21st century we witness a new thrust of enterprises and employees striving to implement a 4 day work schedule by at the same time organizing a further reduction of work hours. The scientific evidence which is based on pre- and post trial assessments of workers satisfaction shows rather positive results (Fan, Schor, Kelly, Gu 2025). More studies are due to accompany this potential of further health and wellbeing effects of reduced work time and the reorganization of work time in enterprises.
