Light and Sleep


Melatonin is a naturally occurring hormone controlled by light exposure that helps regulate your sleep-wake cycle. Your brain secretes more melatonin when it’s dark—making you sleepy—and less when it’s light—making you more alert. However, many aspects of modern life can alter your body’s production of melatonin and shift your circadian rhythm.

Use these tips to keep your sleep-wake cycle on track.

During the day:

  • Expose yourself to bright sunlight in the morning. The closer to the time you get up, the better. Have your coffee outside, for example, or eat breakfast by a sunny window. The light on your face will help you wake up.
  • Spend more time outside during daylight. Take your work breaks outside in sunlight, exercise outside, or walk your dog during the day instead of at night.
  • Let as much natural light into your home or workspace as possible. Keep curtains and blinds open during the day, and try to move your desk closer to the window.
  • If necessary, use a light therapy box. This simulates sunshine and can be especially useful during short winter days.

At night:

  • Avoid bright screens within 1-2 hours of your bedtime. The blue light emitted by your phone, tablet, computer, or TV is especially disruptive. You can minimize the impact by using devices with smaller screens, turning the brightness down, or using light-altering software such as f.lux.
  • Say no to late-night television. Not only does the light from a TV suppress melatonin, but many programs are stimulating rather than relaxing. Try listening to music or audio books instead.
  • Be smart about e-readers. Devices that are backlit, such as the Kindle Fire or the iPad, are more disruptive than e-readers that don’t have their own light source—or good old-fashioned books.
  • When it’s time to sleep, make sure the room is dark. Use heavy curtains or shades to block light from windows, or try a sleep mask. Also consider covering up electronics that emit light.
  • Keep the lights down if you get up during the night. If you need some light to move around safely, try installing a dim nightlight in the hall or bathroom or using a small flashlight. This will make it easier for you to fall back to sleep.

And then there are the Owls

Things get more difficult if you work the night shift. The above “during the day” recommendations don’t really work. using a light therapy box can be helpful. Use it once you get up. Taking melatonin about 1 hour before you go to sleep can also be helpful. All the “at night” suggestions still apply to the Owls when sleeping during the day.
