The next time you’re struggling with insomnia or just can’t seem to fall asleep, try throwing on a pair of amber/orange tinted sunglasses. By doing this an hour before going to sleep, you can increase the amount of melatonin in your brain, which is the hormone that regulates the sleep and wake cycle in your brain.
It’s basically like creating a fake sunset for your brain, to make it think that it’s closer to bedtime than it actually is. A lot of people use this technique to get over jet lag when they are travelling. It also works great if your sleeping patterns are just plain out of whack.
