6. Go camping
Because the circadian rhythm is regulated primarily by exposure to light, the best way to reset your sleep schedule and get back on the right track is by exposing yourself to as much natural light as possible, with plenty of bright light during the day and no light at night. And one of the best ways to accomplish that is by going camping.
One study found that being exposed to only natural light for a few days realigns the circadian rhythm with sunset and sunrise, resulting in an easier time falling asleep and staying asleep. (31) And if you’re wondering about exposure to moonlight at night, it doesn’t appear to hinder these effects. Despite the fact that the moon can seem quite bright, moonlight is only around 0.1 to 0.4 lux. (32, 33) For comparison, a candle one meter away is 1 lux.
