Spending long days in an office away from natural light, for example, can impact your daytime wakefulness and make your brain sleepy. Then bright lights at night—especially from hours spent in front of the TV or computer screen—can hold back your body's production of melatonin and make it harder to sleep, However, there are ways for you to naturally regulate your sleep-wake cycle, improve your body's production of melatonin, and keep your brain on a

　　healthy schedule.

　　Increase light exposure during the day

　　☆Remove your sunglasses in the morning and let light onto your face.

　　☆Spend more time outside during daylight. Try to take your work breaks outside in sun light, exercise outside, or walk your dog during the day instead of at night.

　　☆Let as much light into your home/workspace as possible. Keep curtains and blinds open during the day, move your desk closer to the window.

　　☆If necessary, use a light treatment box. A light treatment box can create sunshine and can be especially useful during short winter days when there's limited daylight.

　　Improve melatonin production at night

　　☆Turn off your television and computer. Many people use the television to fall asleep or relax at the end of the day. Not only does the light hold back melatonin production, but television can actually excite the mind, rather than relaxing it. Try listening to music or audio books, or practicing relaxation exercises. If your favorite TV show is on late at night, record it for viewing earlier in the day.
