Staring at glowing screens in bed depresses the release of melatonin, a sleep-inducing hormone.
So you should turn off that TV/computer/phone/XBox before you go to bed.
At least that’s what’s argued by a study from the National Sleep Foundation (yes, it exists), backed by impressive-sounding doctors who work at places like Harvard Medical School.
95% of people questioned in a NSF study say they use some type of electronic device before going to sleep. The NSF argues that this type of behaviour costs us in precious sleep hours.
Something to keep in mind.
