You might want to move your bedroom outside if you toss and turn at night.
Researchers say a few days of camping is enough to help reset your body clocks.
Researchers studied five people who camped in the middle of winter in Colorado.
They didn't have any artificial light like mobile devices or flashlights.
The campers melatonin levels shifted over a week and people went to sleep earlier.
Experts say you can help this process along by cutting back on artificial light at night and getting more natural sunlight during the day.
