7 things you should never do before going to bed

Don’t work in bed (or anywhere in the bedroom).

Experts advise reserving the bedroom for sleep and s*x exclusively. Otherwise, you won’t associate the bedroom with rest — and might have a harder time falling asleep.

 Don’t consume caffeine after 5 p.m.

One study found that consuming 400 milligrams of caffeine (that’s about how much is in a Starbucks Venti coffee) even six hours before bedtime disrupted sleep. Specifically, those who consumed a caffeine pill six hours before bed slept about an hour less than they slept when they didn’t consume caffeine. The researchers suggest that people limit their caffeine consumption to before 5 p.m., at the latest.
