According to the American Sleep Association, one in every three adults experiences occasional insomnia, while another one in 10 has chronic insomnia. While most of us crave a good night’s sleep for the short-term benefit of feeling more alert, we also realize that sleep is crucial to our health. During those nightly hours of shut-eye, our bodies experience a prolonged period of repair and renewal that can improve everything from treatment of chronic conditions to weight management.
How much sleep do seniors need? Sometimes you’ll hear that you need less sleep as you get older, but that is incorrect. A 2014 study revealed that seniors actually require similar amounts of sleep as younger adults, as much as 9 hours, although they only get 7.5 hours on average. The issue is that with age, the neurons responsible for regulating our sleep patterns slowly die off. This causes seniors to wake up even if they’re not fully rested, and to suffer from insomnia that makes it difficult to fall asleep in the first place.
Olson also advises that those who turn to over-the-counter sleep aids do so intermittently, to help avoid building a habit, and to check with their doctors that the medicine doesn't interfere with any of their conditions or medications. If you wind up on a Food and Drug Administration-approved prescription sleep aid, Walia points out that it should be for the short term.
Memory consolidation: While you sleep, the brain repeatedly replays remembered events from that day; if these phases are interrupted, memories aren’t fully formed, or even not formed at all. This is part of what helps you learn new skills. One study found that mice doing an hour’s training followed by sleep would ‘learn more’ than mice who did three hours of training but were then sleep deprived. This process is the result of connections forming between neurons, which happens more often during sleep.
But with schools continuing to open at ridiculously early times and bosses still mostly unwilling to embrace the science calling for shorter workdays, it's hard to see how most of us are realistically going to either sleep in later or get to bed earlier (especially if, you know, you want to squeeze in fluffy extras like seeing your loved ones, feeding yourself, and enjoying life in the evenings).
Valerian is one of the most common sleep remedies for insomnia. Numerous studies have found that valerian improves deep sleep, speed of falling asleep, and overall quality of sleep. However, it's most effective when used over a longer period of time. One caveat? About 10% of the people who use it actually feel energized, which may keep them awake. If that happens to you, take valerian during the day. Otherwise, take 200 to 800 milligrams before bed.
Adjust the thermostat. If you’re too hot or too cold at bedtime, sleep isn’t going to come easy. While there’s no ideal temperature for everyone, most people sleep comfortably when the bedroom is between 60 and 67 degrees. As you start to feel drowsy, your body temperature drops, which in turn helps you drift off to sleep. A cooler bedroom facilitates that. Don’t cool it off too much, though — shivering in bed isn’t conducive to a good night’s sleep.
