things you might have been told about sleep but aren’t completely true.
More Sleep Is Better for You
There could be such a thing as too much sleep. The amount of sleep we need varies by person and also changes as we age. Harvard researchers found that a lot of sleep (9 hours or more) is linked with poor sleep quality. So don’t aim for more sleep—even on the weekends. Aim for better sleep.
Alcohol Helps You Sleep
Alcohol, the original nightcap, can help most people fall asleep. However, it also can cause you to wake up more during the night, wrecking your sleep quality. Consider drinking non-alcoholic beer before bed instead.
