No Blue Light Before Bed
Welcome to day 4 of the Your Best Sleep Yet! challenge, powered by support from Compass One Healthcare.
Proper use of light keeps your circadian rhythm in check. Every person’s behavioral, mental, and physical changes follow a daily cycle. Light affects it — sleeping at night and being awake during the day is one example of a light-related circadian rhythm. Light up your life (at the right time).
If you sleep at night, blue light can be particularly stimulating to the brain chemicals that tell your body to wake up. It comes from your TV screen, tablet, or phone. Avoid blue light before bed by either avoiding screens, using the blue light filter on your smartphone, or wearing blue light-blocking glasses.
During the day, keep things bright. Get exposure to light soon after awakening. Light is the most important signal to your brain that it’s time to be alert and start your day. Both artificial and naturally-occurring light help stimulate your brain to wake up.
If you sleep during the day, use blackout curtains to keep your room dark. Avoid blue light from screens too close to bedtime. Keep your room cool, and use some type of white noise to drown out daytime sounds like lawn mowers or traffic.
