Healthy Sleep Tied to 40% Reduced Risk of Dying

Healthy Sleep Tied to 40% Reduced Risk of Dying

Consistent regular bed and wake times, with optimal sleep duration, might just be the single best way to reduce your risk of dying

In a recent study, researchers estimated the association of regular sleep (of optimal sleep duration) with all-cause mortality using data from 1759 adults in the Multi-Ethnic Study of Atherosclerosis Sleep Study. During 7 years of follow up, 176 people died. The regular-optimal group had a 39% lower mortality risk compared to the irregular-insufficient sleep group.

The regular and optimal duration sleep pattern maps behaviourally to regular bed and wake times, suggesting potential health benefits of adherence to recommended sleep practices, the researchers note.

We know our bodies have an internal clock, known as the circadian rhythm, which regulates various biological processes, including sleep-wake cycles. Sticking to a consistent sleep schedule allows your body to align its natural rhythm with the external day-night cycle. This synchronization promotes better sleep quality and therefore better health.

The AASM recommends adults try to aim for at least 7 hours of sleep.
