Positive relationship between more hours of sleep and wellbeing

A sleep and wellbeing study from the US has shown that Americans who report that they usually get more hours of sleep per night have higher overall wellbeing than those who typically get fewer hours of sleep. Getting more hours of sleep is positively associated with having higher wellbeing, with the relationship peaking at eight hours and levelling off thereafter.
The link between getting more hours of sleep and higher wellbeing does differ slightly by age. For adults aged 65 and older, the relationship peaks at seven hours of sleep. For those under age 65, it peaks at eight hours. For young adults aged 18 to 29, the wellbeing uptick from seven to eight hours is more pronounced than it is for adults in the middle age groups.
Americans aged 30 to 64 who usually get five hours of sleep have significantly lower wellbeing than those who usually get six hours of sleep, which is not the case for young adults or seniors.
A strong relationship between sleep and well-being exists. However, the direction of the relationship is unclear. Getting more hours of sleep could boost wellbeing, – but then those with higher wellbeing may be more likely than those with lower wellbeing to get more sleep.
More than four in 10 adults fall short of recommended amount of sleep
Forty-two percent of US adults report getting less than seven hours of sleep on a typical night, the minimum number of hours recommended by the National Sleep Foundation for those aged 18 and older. And although young adults who get eight hours of sleep have significantly higher well-being than those who get seven, 67% of 18- to 29-year-olds say they usually get less than eight hours.
