Smart phones, e-readers, tablets, computer screens, TVs, and digital clocks emit blue light, a short frequency of light that may be harmful to the eyes and disrupt sleep. Minimize screen time for several hours before bedtime to get a good night’s rest. Wearing orange tinted glasses that block out blue light may also be helpful. Apps are available for your computer, tablet, and smartphones that prevent the screens from emitting blue light.
Besides blue light exposure, it makes sense to power down several hours before bedtime to maximize your chances of getting a good night’s rest. Cover up any displays that may be visible from your bed, like a digital clock. Black out curtains can block out ambient light from outside.
Nap If You Are Sleep-Deprived
Naps are a good way to get some extra rest if you are tired, but too long of a nap will make sleeping at night harder. The best naps are under 20 minutes. Any longer than that may interfere with nighttime rest. Short naps are proven to boost alertness, mood, and performance. Take a nap in a cool, dark room for maximum benefits. Avoid napping too late in the day as this can also negatively affect nighttime rest. Naps longer than 10 to 20 minutes are associated with sleep inertia which is grogginess and disorientation that occurs for a few minutes up to 30 minutes after waking up from deep rest.
Clock-Watching Increases Anxiety
One of the worst things you can do if you’re having trouble falling or staying asleep is to watch the clock. Watching the seconds, minutes, or hours tick by when your wide awake may produce a lot of anxiety which will not help you sleep better. Avoid the temptation to watch the clock.
