Sleep Regularity Predicts Mortality
Sleep regularity, rather than sleep duration, predicts all-cause mortality according to a recent study. Research on 60,000 individuals with 10 million sleep records from the UK Biobank revealed that the stability of sleeping and waking times is a significant factor in determining longevity. Although sleep duration is important, it does not alone determine life expectancy. Variability in sleep patterns can lead to the suppression of melatonin, a hormone linked to various disorders and diseases.
