Blue light and sleep

Exposure to blue light from the sun as well as our screens boosts mood and alertness—a sunrise signals to our brain that it’s time to wake up. But too much exposure to blue light from screens in the evening can disrupt our body’s natural sleep cycle, known as the circadian rhythm. Light slows the production of melatonin—the sleep hormone—in our body. For more restful sleep, be sure to:

• set devices to night or dark mode in the evening. This setting lowers screen brightness and its warm colors are less likely to confuse your body into thinking it’s daytime.
• avoid using screens one to two hours before going to sleep.
