Keep your room cool, clean, dark, and quiet. Do your best to keep the temperature in your bedroom just below 70 °F (21 °C). Sleeping in a hot and uncomfortable area is not a good or relaxing way to sleep, so do your best to get air regulation throughout the room. Clean up regularly, and change your sheets every 1 to 2 weeks, or whenever they’re dirty. A cluttered space can increase stress, and it can be tough to relax if your sheets are smelly.
Melatonin is the hormone that controls sleep, so it's no wonder that it naturally induces sleep. Although some experts recommend taking higher doses, studies show that lower doses are more effective. Plus, there's concern that too-high doses could cause toxicity as well as raise the risk of depression or infertility. Take 0.3 to 0.5 milligrams before bed.
Melatonin has been used successfully for sleep enhancement in healthy individuals, as well as to reduce feelings of jet lag during global travels. This natural hormone is also being tested as a sleep aid with the elderly and other populations. In addition, studies are focusing on whether or not melatonin can help improve sleep patterns in individuals with depression.
Use a blue light filter on your device. The blue light emitted by smartphones and tablets can be a powerful sleep disruptor. It suppresses your body’s production of melatonin and throws your circadian rhythm off, making it harder to fall and stay asleep. Luckily, many smartphones these days have a “night shift” feature that adjusts the screen from cool (blue) to warm (yellow) light, which is less likely to keep you up past your bedtime. Likewise, there are apps you can run on your laptop or tablet that reduce blue light. Some popular ones are f.lux and Twilight.
