Improved sleep

Your body's internal clock follows the sun, making you feel awake during the day and tired at night. Although artificial illumination can mimic natural light, direct sunlight has 200 times the intensity of office lights inside a small space. Therefore, sunlight has a greater impact on your circadian rhythm than artificial light.

By being exposed to sunlight, you can get better sleep because of the following benefits: helping you feel more tired at night; shortening the time it takes to fall asleep and improving the quality of your rest. You merely have to go outside to get your daily dosage. Just remember that sunlight must enter your eyes in order to affect your circadian rhythm. Picnicking on the beach may be more beneficial for improving sleep than taking a nap in a quiet, wooded area.
