Tip 3. Get plenty of natural light and some exercise in the day
Exposing yourself bright, natural daylight in the day for about 15 minutes, has been shown help support your circadian rhythm to distinguish the difference between night and day and so help you regulate your sleep patterns so you get used to better nights sleep. The most important environmental factor for regulating the caiman rhythm is light entering the eye as it helps your brain know its day time. As mentioned in previous posts you can also help by avoiding artificial light at night.
For those who like facts, outdoor natural light ranges from 10,000 to 30,000 lux on a clear day. Whereas ordinary indoor light is between 10 to 300, so not nearly bright enough to have the strong influence on the circadian rhythm we want.
Exercise in the day has also been shown to improve sleep quality at night as well as reduce insomnia. Some
studies even show its as effective as sleeping pills
