A healthy lifestyle has become a public policy issue in France, well beyond simple individual advice. Santé publique France now treats sleep as a health determinant on par with diet and physical activity. European recommendations on hypertension make hygienic-dietary measures non-optional, even before the prescription of medications. This framework changes how daily habits are viewed by health professionals.
The role of sleep in a healthy lifestyle: an underestimated pillar
In France, sleep is now classified among the major health determinants by health authorities. According to data from Santé publique France, the average sleep time for adults aged 18 to 79 is 7 hours and 32 minutes, with significant disparities based on age and gender.
These disparities pose a concrete problem. Insufficient or fragmented sleep increases insulin resistance, disrupts appetite regulation, and reduces recovery capacity after physical exertion. Acting on the duration and quality of sleep produces cascading effects on other health pillars.
To strengthen one’s habits regarding overall health, resources like accrosante.com allow for a deeper understanding of the links between sleep, diet, and physical activity in daily life.
Two concrete levers work better than generic advice on the “evening routine”:
- Set a stable bedtime, including on weekends, as social jetlag (the difference between weekday and weekend schedules) desynchronizes the biological clock over several days
- Reduce exposure to bright screens in the hour before bedtime, not as a principle, but because blue light measurably delays melatonin secretion
- Lower the room temperature to around 18 degrees, which facilitates falling asleep by accelerating the drop in body temperature necessary for deep sleep
Mediterranean diet and salt reduction: what the new recommendations say
The recommendations from the European Society of Cardiology (ESC), communicated in France since 2024, no longer merely suggest a “balanced diet.” They prescribe a precise framework: reducing salt to less than 5 g per day, adopting a Mediterranean-style diet, and losing weight if necessary.
The Mediterranean diet is not a diet in the restrictive sense of the term. It is based on an abundance of vegetables, legumes, fruits, whole grains, olive oil, and fish, with moderate consumption of red meat and ultra-processed products.
The difficulty lies less in knowing these principles than in their concrete application. Ultra-processed foods account for a significant portion of salt intake without the consumer being aware of it. Industrial bread, prepared meals, sauces, and cold cuts concentrate most of the sodium consumed, far more than the salt added at the table.
Reading labels instead of counting calories
Reading the sodium content per serving is more useful than calorie counting for reducing cardiovascular risk. A product labeled “light” may contain more salt than a standard product to compensate for the loss of taste associated with reduced fats.
Gradually replacing processed products with homemade preparations, even simple ones, remains the most direct lever. Cooking legumes in large quantities on the weekend and using them over several meals reduces dependence on prepared dishes without requiring a considerable time investment.
Physical activity: “weekend warriors” achieve comparable results
The WHO recommends at least 150 to 300 minutes of moderate-intensity physical activity per week. This volume may seem incompatible with a busy schedule. The available data provide an interesting nuance: focusing activity on one or two sessions over the weekend offers benefits comparable to a daily distribution, according to studies reported by National Geographic.
This information does not exempt one from limiting sedentary behavior during the week. Sitting for more than eight hours a day partially cancels the benefits of concentrated physical activity. However, it allows for a re-evaluation of the guilt associated with the inability to exercise every day.
The “September Moves” initiative and the redefinition of physical activity
Launched in France, the “September Moves” initiative aims to broaden the definition of physical activity beyond organized sports. Walking, gardening, taking the stairs, or biking count towards the recommended weekly volume. Being physically active does not mean doing sports, but integrating movement into everyday actions.
This approach aligns with the shift of the PNNS (National Nutrition Health Program), which moves the discourse from individual effort to creating supportive environments: bike paths, access to stairs in public buildings, urban planning conducive to walking.
Stress and mental health: the limits of standardized advice
Stress management appears on all lists of advice for a healthy lifestyle. An effective technique for one person (meditation, breathing, journaling) may prove ineffective or counterproductive for another.
The available data do not allow for a conclusion that one stress management technique is universally superior to others. Heart coherence has shown promising results, but its regular practice requires a discipline that many abandon after a few weeks.
- Identifying modifiable sources of stress (commute, workload, screen exposure) often produces more effects than adding a relaxation practice to an already saturated schedule
- Reducing continuous information consumption lowers baseline anxiety levels without additional effort
- Social connection remains a documented protective factor: maintaining regular, even brief, interactions affects perceived stress
Adopting a healthy lifestyle daily does not rely on the accumulation of isolated good practices. Sleep, diet, physical activity, and stress management interact with each other. Improving just one of these pillars often leads to positive effects on the others, making the first step less difficult than it seems.
