The Sleep Habits of the French: Data, Figures, and Trends 2026

Sleep occupies a third of our lives, but the French have an increasingly tense relationship with it. Late bedtimes, forced early wake-ups, difficulties falling asleep, daytime drowsiness: recent surveys from the National Institute of Sleep and Vigilance (INSV) and Public Health France paint a concerning picture. This article gathers the latest data — figures from the Public Health France Barometer 2024, INSV/OpinionWay survey 2025 — to understand the current state of French nights, which populations are the most vulnerable, and what levers can concretely improve sleep quality.

How many hours do the French really sleep?

The question of sleep duration is often the first one asked — and the answer holds some surprises. According to the Public Health France Barometer 2024, adults aged 18 to 79 report sleeping an average of 7 hours and 32 minutes per 24 hours, including naps. This figure, initially reassuring, deserves some nuance.

Young adults and seniors sleep more, while those aged 40 to 59 are the most affected by reduced sleep. In other words, the national average masks a very uneven distribution based on age and professional status.

More than one in five adults sleeps 6 hours or less per night during the week. This threshold is clinically significant: below 6 hours of sleep, the risks for cardiovascular, metabolic, and cognitive health are documented. The Barometer notes that 21.5% of adults are considered “short sleepers,” a proportion far from anecdotal.

In terms of specific times, the OpinionWay 2025 survey conducted for the INSV and the VINCI Autoroutes Foundation shows that the French go to bed on average at 11:11 PM during the week (compared to 11:06 PM in 2024) and at 11:55 PM on weekends (compared to 11:46 PM in 2024). Wake-up occurs on average at 6:30 AM during the week. Thus, we are far from the 8 hours recommended for most adults — and this trend is worsening year after year.

However, sleep duration has slightly increased compared to 2024 — reaching 7 hours and 4 minutes on weekdays and 7 hours and 38 minutes on holidays — with the French falling asleep more quickly than in 2024: 31 minutes compared to 37 minutes during the week. A slight improvement, but still well below levels observed before 2020.

One third of the French population reports insomnia complaints

Beyond raw duration, it is the quality of sleep that poses the most problems. One in three French people claims to suffer from insomnia, according to the 2024 Public Health France Barometer. Insomnia is precisely defined here: taking more than 30 minutes to fall asleep, or waking up at least 30 minutes during the night, at least three times a week.

Between 30% and 50% of adults in France reported experiencing a sleep disorder, and using a stricter classification such as that of the DSM-IV, the prevalence of insomnia affected between 15% and 20% of the population. Women are consistently more affected than men, a constant observed in all French epidemiological studies.

These sleep disorders concern more vulnerable populations — a finding that makes sleep an issue of social justice as much as public health. Residents of the Overseas Departments and Regions are also overrepresented: more than 30% of adults in the Caribbean and Guyana are affected by insufficient sleep.

Daytime drowsiness: an underestimated alarm signal

Insufficient sleep at night has a direct and measurable consequence during the day: drowsiness. The INSV/OpinionWay 2025 survey reveals that more than a quarter of the French population suffers from drowsiness, a phenomenon particularly pronounced among young adults, night workers, and those with irregular schedules.

Drowsiness is not just a temporary fatigue. It impairs concentration, slows reflexes, degrades mood, and increases the risk of accidents. On the road, it is one of the leading causes of mortality: driving while drowsy is equivalent, in terms of reaction time, to driving under the influence of alcohol. The INSV emphasizes that drowsiness while driving poses a major risk and calls for better recognition of this disorder by both the public and healthcare professionals.

Mentally, the INSV 2025 survey highlights the deterioration, since 2020, of the mental health of the French, particularly among young adults, and the concomitant rise in drowsiness — two closely linked phenomena. Chronic drowsiness can indeed be both a cause and a consequence of anxiety and depressive disorders: a vicious circle that is difficult to break without specific intervention.

Young adults: the most deficit generation

Among all age groups, those aged 18-24 concentrate the most alarming indicators. In 2024, 18-24-year-olds went to bed on average at 11:43 PM during the week and at 12:39 AM on weekends, taking 53.3 minutes to fall asleep during the week. These very delayed hours are incompatible with an early morning wake-up required by studies or work, leading to chronic sleep debt throughout the week.

29% of adults aged 18 to 29 are in a state of insomnia complaint, a proportion significantly higher than the national average. The overrepresentation of screens in their evenings — smartphones, social networks, streaming platforms — is regularly pointed out by specialists as one of the main factors contributing to this phase shift. The blue light emitted by screens inhibits melatonin secretion and delays falling asleep, even when fatigue is present.

With increasingly demanding lifestyles, omnipresent digital usage, and shifted sleep schedules, the French sleep an average of too little, which directly impacts their alertness and health.

Territorial and social inequalities in sleep

Sleep is not distributed uniformly across French territory. Brittany and the Pays de la Loire stand out for having higher sleep times, while the Provence-Alpes-Côte d’Azur region shows an average duration of 7 hours and 26 minutes. However, the most significant disparities are observed between mainland France and the Overseas Departments and Regions (DROM), where economic constraints, atypical work hours, and housing conditions heavily impact sleep quality.

Beyond geography, the standard of living plays a decisive role. People in precarious situations often accumulate several unfavorable factors: noisier housing, less regular work hours, chronic financial stress, limited access to specialized care. Sleep thus becomes a revealer of social health inequalities — an angle that the interministerial roadmap Sleep 2025-2026 seeks to address.

These findings have contributed to shaping the interministerial roadmap Sleep 2025-2026, which aims to promote sleep as an essential determinant of health.

Napping, an underutilized tool

In this concerning picture, napping appears as one of the few practices on the rise. 46% of the French take at least one nap per week, with an average duration of 1 hour and 16 minutes. Although this duration may seem long compared to recommendations — specialists generally advise naps of 10 to 20 minutes to avoid entering deep sleep and to prevent inertia upon waking — the habit itself reflects a growing awareness of the need to recover.

A short nap, taken in the early afternoon, is one of the best-documented strategies to partially compensate for nighttime deficits. It improves alertness, working memory, and mood, without substituting for a full and restorative night’s sleep. To make the most of it, it should be limited to 20 minutes and avoided after 3 PM.

How to concretely improve the quality of your sleep?

The data is compelling, but it is not a fatality. Several simple habits, validated by sleep specialists, can significantly reduce the time it takes to fall asleep and improve the quality of nighttime cycles.

Maintain regular hours. Going to bed and waking up at the same time every day — including weekends — is one of the most effective measures to synchronize the internal biological clock. Large variations in schedule between weekdays and weekends, often referred to as “social jet lag,” desynchronize the circadian rhythm and degrade sleep quality over time.

Limit screen exposure in the evening. Turning off screens at least one hour before bedtime reduces melatonin inhibition and facilitates falling asleep. If evening screen use is unavoidable, activating “warm light” modes or using blue light filter glasses can mitigate the impact.

Care for the sleep environment. A cool room (between 16 and 18 °C), dark, and quiet constitutes the ideal setting. The mattress and box spring also play a significant role: an unsuitable bed — too firm, too soft, or worn out — disrupts sleep cycles, generates musculoskeletal pain, and promotes micro-awakenings.

Engage in regular physical activity, but not too late. Physical exercise improves the quality of deep sleep, provided it is not practiced in the two hours before bedtime, as it may raise body temperature and delay falling asleep.
