Unfortunately, a person can't just accumulate sleep deprivation and then log many hours of sleep to make up for it (although paying back "sleep debt" is always a good idea if you're sleep deprived). The best sleep habits are consistent, healthy routines that allow all of us, regardless of our age, to meet our sleep needs every night, and keep on top of life's challenges every day.
After talking with doctors and examining clinical studies, we learned that the research surrounding common remedies for restless nights, like melatonin and valerian, is often contradictory. To find the best sleep aid, it’s important to look for an active ingredient that suits your particular sleep problems — and to pay close attention to your dosage and timing.
Some of our expectations regarding our sleep might be slightly misguided. As an example, the thought that we will fall asleep almost immediately upon retiring to our beds may be improper. It should normally occur in less than 15 to 20 minutes, but it may take as long as 30 minutes as we get older. In fact, people who fall asleep in less than five minutes may be "pathologically sleepy." This means that they are so sleepy that they fall asleep quicker than might be normal. In some cases, this ability to fall asleep quickly—and enter rapid eye movement (REM) sleep quickly—can be seen in excessive daytime sleepiness that might occur in sleep deprivation or narcolepsy.
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.
