Building better sleep habits could cut the risk of early death by almost a quarter and add up to four years to life expectancy, according to a major new study.
The analysis by insurance company Vitality and the London School of Economics (LSE), based on 47 million nights of sleep linked to hospital and insurance records, found that people who had seven hours’ sleep and a consistent bedtime had a 24 per cent lower mortality risk than those with irregular or shorter sleep patterns.
