What “Optimal” Health Is Really Costing You — The Hidden Price Nobody Talks About
▶ Are people getting enough sleep?
About a third of US adults don’t meet the recommended amount of 7 to 9 hours of sleep per night.58
▶ Is getting more than the recommended amount better?
Not necessarily.
It seems that 7 to 9 hours of sleep a night is ideal in terms of health outcomes.56
Interestingly, longer sleep duration (over 9 hours per night on average) is associated with an increased risk of cardiovascular disease, type 2 diabetes, and overall mortality.59 60 61
However, it’s not clear that these risks are caused by sleeping more. Just as likely, it may be other health problems (such as depression, sleep apnea, or heavy alcohol consumption) that lead to both longer sleep times and higher health risks.
