You’ve likely been told over and over again that a good night’s rest equals eight hours of sleep. But research shows it’s not the number of hours you sleep that matters the most – it’s the quality of the hours you are getting. The largest sleep study ever conducted on 1.1 million people shows that it’s quality, not quantity, that matters most. The researchers found that participants who slept only six and a half hours a night lived longer than those who slept eight hours. It’s easy to conclude that you’ll live longer if you sleep for six and a half hours a night, but the reality is more complicated. It’s possible that the healthiest people simply need less sleep. And when you’re getting good-quality sleep, you likely need less of it.
It’s actually pretty normal to wake up during the night, anyway. In The Canterbury Tales, one of the oldest manuscripts in English culture, they describe “second sleep.” There’s some evidence that we used to go to bed when the sun went down, then wake up for a little bit at night—putter around, make sure we’re not getting eaten by a lion—and then go back to sleep. So it’s pretty normal to like wake up in the middle of the night and use the bathroom or whatever.
When it comes to sleep, the less blue light you expose yourself to in the hours before bedtime, the better. Light of any kind can suppress your body’s production of melatonin, but blue light waves do so more powerfully, thereby shifting sleep-friendly circadian rhythms, says Harvard Health Publications. Besides electronic devices like tablets and smartphones, the biggest blue-light offenders in your home are likely fluorescent lightbulbs and LED lights, which many people use because of their energy efficiency and powerful light. Give yourself a romantic break from all the blue and eat dinner by candlelight.
Cough-and-cold products have not been shown to be safe or effective in children younger than 6 years. Therefore, do not use this product to treat cold symptoms in children younger than 6 years unless specifically directed by the doctor.

Science says, we’re supposed to get sleepy when the sun sets, but since we spend most of our nights indoors basking in the glow of our cell phones and tablets, our brains still think it’s daytime and refuse to shut down. So, here’s what you do: Put the gadgets away and watch the sunset. It being winter and all, that can be difficult. Philips’ Wake-Up Light ($180 at Amazon) offers the ability to fake it. Simply, set it to sunset simulation mode; it will gradually decrease light and sound (on your timeline) to help prepare your body for rest.
It’s tempting to reach for coffee when we’re tired after a poor night’s sleep, but drinking caffeine can make it harder for us to fall asleep at night, creating a vicious cycle. Effects of caffeine on sleep and cognition. Snel J, Lorist MM. Progress in brain research, 2011, Aug.;190():1875-7855. Can’t quit cold turkey? Try limiting caffeine intake to earlier in the day so it’s out of your system by bedtime.
"If you find yourself unable to fall asleep, get up and go into another room. Stay up as long as you wish and then return to the bedroom to sleep. Although we do not want you to watch the clock, we want you to get out of bed if you do not fall asleep immediately. Remember the goal is to associate your bed with falling asleep quickly! If you are in bed more than about 10 minutes without falling asleep and have not gotten up, you are not following this instruction."
Another method for determining your sleep need is to take a "sleep vacation." During a two-week period, when you have a flexible schedule or perhaps are on vacation, pick a consistent bedtime and do not use an alarm clock to wake up. Chances are that for the first few days or week you will sleep longer because you'll be paying off your "sleep debt"—the amount of sleep deprivation that you've accumulated over a period of time. If you continue going to bed at the same time and allowing your body to wake up naturally, you will eventually establish a pattern of sleeping essentially the same amount of time each night, probably in the range of 7 to 9 hours. Congratulations! You've identified the amount of sleep that you need.

Finally, you may find yourself turning to over-the-counter medications to help your sleep. One of the most common is a naturally occurring hormone called melatonin. It is sold in many pharmacies and herbal supplement stores. It can be highly effective if you have insomnia related to a poorly timed circadian rhythm. As it has a low risk of major side effects (the most frequent is sleepiness), it might be an option to consider. Other herbal supplements (such as valerian root) do not have a lot of research supporting their efficacy.

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.
