Early or late bedtimes may result in individuals missing cues that help reset body clock each day
When it comes to sleep, Goldilocks may have argued the trick is to find a bed that is “just right” but research suggests there may also be an optimal time to nod off – at least when it comes to heart health. Not too early and not too late, with the sweet spot being between 10pm and 11pm.
The study, based on data from more than 88,000 participants of the UK Biobank, suggests going to sleep at 10pm or shortly after is associated with a lower risk of developing cardiovascular disease compared with falling asleep earlier or later at night.
