The Science of Sleep and Longevity
A good night’s sleep shapes far more than how you feel tomorrow. As a foundational biological process, sleep underpins long-term health, resilience and overall wellbeing.
What the Research Shows
During regular, restorative sleep, the body supports cellular repair, nervous system regulation and metabolic balance, while the brain clears accumulated waste from waking hours.
Growing evidence suggests that how consistently you sleep may be just as important as how long you sleep. Research has found that higher sleep regularity is associated with a 20–48% lower risk of all-cause mortality.¹
In parallel, a large population-based study linked maintaining healthy sleep habits with meaningful gains in life expectancy.²
Sleep Patterns Linked to Longevity
The science points to a consistent sleep rhythm that typically includes:
-
Around 7–8 hours of sleep per night
-
Falling asleep with ease
-
Staying asleep through the night
-
Waking feeling restored
Over time, disrupted or irregular sleep may place ongoing strain on these systems, while consistent sleep rhythms help the body function more efficiently, supporting long-term health.
How to Support Restorative Sleep
If you’re not sleeping well, you’re not alone — nearly 1 in 3 adults struggle to fall or stay asleep.³
