Turn off the gadgets well before bed
Electric light after dark can affect our patterns of slumber.
Do you look at an electronic device after darkness has fallen outside? Maybe you watch TV, go onto a computer, read on a tablet or play on a console or phone. It might be worth rethinking those late night blasts of light into the eyes.
Because that light is not just allowing you to see something, it is also having an effect in your internal body clock.
In a recent article in Nature, Charles A. Czeisler from the Division of Sleep Medicine, at Harvard Medical School explains how electric light, and particularly LEDs, can affect our patterns of slumber.
“Technology has effectively decoupled us from the natural 24-hour day to which our bodies evolved, driving us to go to bed later,” he writes, adding that: “The more we light up our lives, the less we seem to sleep.”
