Longevity and wellness in figures: what the sources say
Ten verified figures, with their sources, to place longevity and wellness in France and worldwide: life expectancy, years lived without disability, sleep, physical activity, the weight of the wellness economy, visitor numbers on the French Riviera. They describe a context; they promise nothing, and REGEN GRAY performs no medical act.
Living longer: life expectancy in France
In 2025, life expectancy at birth reached 85.9 years for women and 80.3 years for men in France, according to Insee’s 2025 demographic report (Insee Première no. 2087, January 2026). In twenty years, women have gained 2.1 years and men 3.6 years.
The same year, for the first time since the Second World War, deaths exceeded births in France: the country is ageing, and the question is no longer only to live long, but to live long in good shape.
Living long in good shape: disability-free years
At 65, a woman can expect to live another 11.8 years without disability and a man 10.5 years, according to the DREES study published in January 2026 (Études et Résultats no. 1363, 2024 data). At birth, disability-free life expectancy is 64.1 years for women and 63.7 years for men.
Side by side, these two series say the essential: a woman lives on average close to 86 years, around 64 of them without limitation; a man a little over 80 years, around 64 of them without limitation. In between, some twenty years lived with impairments. Since 2008, disability-free years at 65 have progressed by one year and nine months; since 2019, progress has slowed markedly (four months for women, one month for men).
Sleep and movement, two foundations
Adults aged 18 to 79 sleep an average of 7 h 32 per 24 hours in France, and 21.5% of them are short sleepers, at six hours or less, according to Santé publique France’s 2024 Barometer. People aged 40 to 59 and men are the most affected.
Worldwide, 31% of adults, 1.8 billion people, do not reach the recommended 150 minutes of physical activity a week, according to the WHO study published in The Lancet Global Health in June 2024. In high-income Western countries the share is 28%. It was 23.4% in 2000 and could reach 35% by 2030.
Wellness as an economy
The global wellness economy reached 6.8 trillion dollars in 2024, up 7.9% in a year, and should approach 9.8 trillion in 2029, according to the Global Wellness Economy Monitor 2025 of the Global Wellness Institute.
On the consumer side, 84% of Americans surveyed place wellness among their top priorities, according to McKinsey’s Future of Wellness survey (2025, around 9,000 people in four countries). The firm puts the global consumer wellness market at around 2 trillion dollars.
The French Riviera, a public that comes from afar
Summer 2025: hotels on the Côte d’Azur posted 86% average occupancy over June and July, and foreign guests accounted for 58% of nights in hotels and residences, according to the summer 2025 report of Côte d’Azur France Tourisme. Over 2025 as a whole, the Provence-Alpes-Côte d’Azur region counted 24.8 million hotel nights, up 3%, according to the 2025 regional hotel report.
That is REGEN GRAY’s public: Cannes residents who want a routine, and visitors passing through, one street behind the Croisette, looking for an hour of recovery between two appointments.

What these figures do not say
None of these figures measures the effect of a red light, oxygen chamber or capsule session. REGEN GRAY claims no effect on life expectancy or on health: sessions are a matter of wellness, relaxation and recovery as experienced, with no medical act, no diagnosis, no prescription. The source is given for every figure; this page is reviewed at each new publication by the bodies cited.
Frequently asked questions
Why does a wellness centre publish these figures?
Because our clients ask us these questions, and the answers sit in public sources few people read. We gather them, with their origin, so that anyone can check.
Do REGEN GRAY sessions extend life expectancy?
No, and we never claim so. REGEN GRAY offers wellness, relaxation and recovery sessions, with no medical act. The figures on this page describe a context, not a result.
Where do the figures come from?
From Insee, DREES, Santé publique France, the WHO, the Global Wellness Institute, McKinsey and the regional tourism boards. Each figure links to its source.
How often is the page updated?
At each new publication by the bodies cited, generally once a year for each. The update date is at the bottom of the page.
