Loss of green

In many instances we learn only if we have lost something. The loss of biodiversity is rather abstract. The loss of a favorite green, allay or park due to a severe drought, however, is fairly visible. The point of departure of the Tour de France more than 100 years ago in Montgeron and the green alley which was built to allow to ride through the Forêt de Sénart to Fontainebleau has suffered from the 2026 repeated heatwaves and droughts. The scientific evidence accumulates to the manmade responsibilities over time. What used to be a fantastic area for leisure and walks after work has turned into a dusty place. Even the recent efforts to improve the greenery further has been surpassed by the unexpected lack of precipitation, although forecasted by some scientists. The costs of climate change, global warming and therefore more difficult water management become pressing policy issues.

Activity and dementia

In view of the huge challenge of dementia to people and the public health systems, it is primordial to test potential remedies with high precision. So far general measures of just any physical activity like walking were considered beneficial. Recent and more comprehensive data on domain-specific physical activities by Feter et al. (2026) emphasize the importance to differentiate between walking for leisure or walking rather stressed to work. The former contributes to a delay of the onset of dementia, whereas the latter bears higher risks of dementia due to the “negative” stress involved. However, as Kivimäki and Hamer (2026) point out dementia itself has a long gestation period in which persons might reduce physical activities because a “silent” onset of dementia is not yet diagnosed but inhibits already more activities. Commuting to work or leisure might already be a challenge in early dementia particularly if public transport has to be organized independently.

Gardening culture

There is a specific set of skills attached to gardening culture. You do not have to travel continents to experience the pleasure of gardening from more than just your own culture. Beyond the tradition of the French garden “à la Le Nôtre”, the English garden including the short precisely trimmed lawn and blooming arrangements, the Japanese gardens have a wholistic approach, which pay attention to broader human experiences of nature. A garden is a kind of sanctuary. It resembles more an internal journey rather than a showing off to others. Walls serve to enhance privacy to be able to open-up again later to others rather than a symbol of distinction and exclusion from the less privileged. Small places suffice to give room to a Bonsai experience. The very busy seaside resorts and port of Ostend on the Belgian coast has reserved a small spot for inner peace in its Japanese garden.

Waterfront Paris

Most people enjoy the banks of the river “La Seine” in Paris. Ever since the Olympics in Paris 2024, the temptation to go swimming there or to do some other kind of water related activities, is high. Fewer people are aware of an other splendid location near the Gare de l’Est. The canal Saint Martin and the nearby end of the Canal de l’Ourcq ( image below) have much to offer for stressed people to take some time off and relax. From cinemas, cafés and bars you can choose your favorite to pass time with friends or family, alternatively just keep walking for miles to get your exercise as needed to sustain your body in good health and shape. The health impact of such cool and more humid areas has a high value to the benefit of all without forcing people to travel long distances for recreational activities or normalizing weight or heart rates. 

 

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. 

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.

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. 

Sedentary Lifestyle

There seems to exist a correlation between a more sedentary lifestyle and the level of industrialization. Industrialized countries have attempted to beat the running of time by faster modes of transport. From horses to cars, trains and airplanes. As a corollary of wanting to go faster the number steps walking has decreased compared to countries with less private or public means of transportation. The the time you spend sitting in transport the less we tend to walk or cycle. Obesity has become a dangerous consequence for large parts of those sedentary individuals and sedentary societies. The contribution by Paul Klotz in “Le Monde” from 2025-7-26 (p.24) highlights the bio-psycho-socio co-determination of the sedentary lifestyle. Societal developments to build entire cities more suited to car and train traffic has made walking the city a stressful task. Rebuilding our cities with a focus for a society on the move again is a challenge for more than one generation.

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.

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.
