An ultra short episode of sleep is sufficient to promote declarative memory performance. Lahl O, Wispel C, Willigens B. Journal of sleep research, 2008, Apr.;17(1):1365-2869. But try to avoid napping after 3:00 or 4:00pm, as this can make it harder to fall asleep at bedtime. Effects of afternoon "siesta" naps on sleep, alertness, performance, and circadian rhythms in the elderly. Monk TH, Buysse DJ, Carrier J. Sleep, 2002, Feb.;24(6):0161-8105.
Insomnia is defined as the inability to fall asleep, remain asleep, or get the amount of sleep an individual needs to wake up feeling rested. Its symptoms include difficulty falling asleep, frequent wake-ups during the night, waking up too early in the morning, daytime sleepiness, difficulty concentrating, and irritability. Insomnia can be acute (lasting one to several nights) or chronic (lasting from a month to years). It’s also the most common sleep complaint among Americans (especially women).
If you experience frequent insomnia, you’ve probably already tried the basics, like cutting back on caffeine and alcohol. Maybe you’ve also turned to the medications, luxury mattresses and pillows, white-noise machines, and other remedies that make up the $41 billion Americans spent on sleep aids and remedies in 2015, according to a report from BCC Research. But you might be wary, understandably, of relying on drugs.
Use sleeping aids and devices: Experiment with white noise machines, adjustable beds, sleep masks, and indoor air purifiers if you need help sleeping. White noise machines or noise reducers create ambient or white noise, which makes it more difficult for a sleeper to hear any potentially disruptive noises. Adjustable beds can alleviate pain that can disturb sleep, especially for those suffering from hip and knee pain or acid reflux disease. A sleep mask tricks the brain into falling asleep more quickly for people who need to sleep or nap during daylight, and indoor air purifiers lessen symptoms suffered by those with allergies or nasal congestion.
Exercising in the morning may help you sleep better than working out in the afternoon or evening. In an unpublished study presented at the 58th meeting of the American College of Sports Medicine, researchers at Appalachian State University in Boone, North Carolina, found that people spent 85 percent more time in light sleep and 75 percent more time in deep sleep when they worked out at 7 a.m. compared with working out later in the day. The authors aren’t sure why, but they believe early-bird workouts affect levels of stress hormones in a way that leads to better sleep quality later on. More research is needed to confirm these finding.
