Having trouble sleeping? Experts say sleeping in a tent could cure your insomnia.
They say exposure to natural light of dawn and dusk helps synchronize our body clocks.
Those who described themselves as night-owls - who struggled to fall asleep in the evening - benefited the most from camping outdoors with nights lit only by a campfire's glow.
Scientists say it took about a week of exposure to natural light-dark cycle to get adjusted. By this time, participants were able to fall asleep easier and be alert in the morning.
But let's face it... camping isn't a realistic option for us all. Scientists say don't worry because there are other ways to make it work.
A morning walk, sitting near a window at work or going for a walk at lunchtime will help boost your energy by exposing you to natural light. In the evening, you need to keep the lights down low and turn electronics off.
