Improving daily life does not always require major upheavals. Recent data on sleep, screen time, and mental load paint a clear picture of the habits that weigh most on well-being, and provide concrete levers to address them. Which adjustments produce a measurable effect, and which are generic advice with no real impact?
Screens and Sleep: The Game-Changing Numbers
Recent surveys on sleep and screens present magnitudes that deserve careful reading.
| Indicator | Source | Data |
|---|---|---|
| French people sleeping with their smartphone turned on next to them | OpinionWay survey for INSV | More than half of the French |
| People woken up at night by notifications | OpinionWay survey for INSV | Nearly a quarter |
| Internet users voluntarily reducing their sleep to stay in front of screens | Insee survey, 2024 | 25% of 15-74 year olds |
The first reflex often advised (turning off screens an hour before bed) is not enough if the phone remains physically in the bedroom. The INSV survey shows that the problem is not just blue light, but the constant availability of the device, which causes micro-awakenings with each notification.
The Insee figure is even more revealing: a quarter of internet users consciously choose to sacrifice sleep for screen time. This is no longer a question of discipline; it is an active selection in favor of screens at the expense of rest.

Nocturnal Doomscrolling: A Mechanism Distinct from Simple Excessive Use
The term “doomscrolling” refers to the compulsive scrolling of anxiety-inducing content, often in the evening or at night. This behavior is now identified as a specific factor in decreased well-being and life satisfaction, distinct from the classic prolonged use of screens.
The difference is technical. Prolonged but chosen screen use (watching a movie, reading an in-depth article) does not have the same effect as passive and repetitive browsing through news feeds. Doomscrolling combines three harmful elements:
- Exposure to unselected negative content, which keeps the nervous system on alert
- Absence of a natural stopping point, as infinite scrolling is designed to hold attention
- A gap between the initial intention (“I’ll watch for five minutes”) and the actual duration, which generates guilt
The most documented remedy does not consist of “limiting screen time” in an abstract way. It involves physically removing access to the news feed after a set time, using an app timer or the phone’s focus mode. The action should be automated, not voluntary each time.
Stress and Mental Load at Work: The Cost of Inaction
Daily tips rarely address work-related stress other than through breathing or meditation advice. Recent data show that the problem has a measurable economic dimension.
Work-related mental health issues weigh on companies in terms of absenteeism, turnover, and decreased productivity. This observation applies to leaders as well, not just employees.
Three Concrete Levers that Do Not Fall Under Personal Development
Reducing mental load in daily life relies less on relaxation techniques and more on structural changes:
- Grouping similar tasks into dedicated time slots rather than scattering them throughout the day, which reduces the cognitive cost of context switching
- Setting a maximum number of minor decisions per day (meals, clothing, routes) by automating recurring choices
- Physically separating work and rest spaces, even in a small home, by assigning a unique function to each area
These adjustments are not spectacular. However, they address the cause (fragmentation of attention) rather than the symptom (the feeling of fatigue).
Domestic Environment and Productivity: Decluttering as a Measurable Tool
Decluttering appears in all competing articles, often in the form of vague advice (“do some decluttering”). Measuring the time lost searching for objects in a poorly organized space allows for a different perspective on the problem.
Studies on workplace ergonomics show that the search for objects or documents accounts for a notable fraction of daily work time. The same principle applies at home: keys, administrative documents, tools, clothing.
The most effective approach is not to “tidy up” but to reduce the number of objects in circulation. Each retained object should have a fixed and unique location. If an object does not have a designated place, it ends up on a free surface and contributes to visual clutter, which increases the ambient cognitive load.
Decluttering is not a one-time activity but a system. Spending fifteen minutes a week on a single category of objects (papers, clothing, kitchen) produces more lasting results than a major annual clean-up, because it prevents the accumulation from taking over again.
The data on sleep, doomscrolling, and mental load all point in the same direction: sustainable improvements in daily life come from environmental changes (removing the phone, automating decisions, assigning a place to each object) rather than from repeated willpower efforts every day. The best practical advice is the one that no longer requires thinking about it once implemented.
