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.
A professor I collaborate with at Penn State named Orfeu Buxton says that 8.5 hours of sleep is the new eight hours. In order to get a healthy eight hours of sleep, which is the amount that many people need, you need to be in bed for 8.5 hours. The standard in the literature is that healthy sleepers spend more than 90% of the time in bed asleep, so if you’re in bed for eight hours, a healthy sleeper might actually sleep for only about 7.2 hours.
Social or recreational drugs like caffeine, nicotine, and alcohol may have a larger impact on your sleep than you realize. Caffeine, which can stay in your system as long as 14 hours, increases the number of times you awaken at night and decreases the total amount of sleep time. This may subsequently affect daytime anxiety and performance. The effects of nicotine are similar to those of caffeine, with a difference being that at low doses, nicotine tends to act as a sedative, while at high doses it causes arousals during sleep.
The herb Vitex agnus castus (chaste tree) may help insomnia during menstrual periods or insomnia that is a side effect of premenstrual syndrome (PMS). In one study, women with moderate to severe premenstrual syndrome were treated with either a vitex agnus castus extract or a placebo for three menstrual cycles. Participants were asked to document their symptoms with a PMS diary with a daily rating scale of 17 symptoms. They reported fewer symptoms, especially less insomnia and negative affect, but their cramps didn't improve. However, chasteberry should not be used by anyone on birth control pills, hormone replacement therapy, or dopamine-related medications, according to the National Center for Complementary and Integrative Health.
Sedative-hypnotic medications (benzodiazepines and non-benzodiazepines) can cause severe allergic reaction, facial swelling, memory lapses, hallucinations, suicidal thoughts or actions, and complex sleep-related behaviors like sleep-walking, sleep-driving (driving while not fully awake, with no memory of the event) and sleep-eating (eating in the middle of the night with no recollection, often resulting in weight-gain). If you experience any unusual sleep-related behavior, consult your doctor immediately.
It makes sense that relaxing with a cup of tea would help you wind down at night, and Cralle says you shouldn't underestimate its soothing power. "I like people to have a nice, relaxing transition from wake to sleep so they don't feel like they need to pop a pill or something," she says. "A cup of chamomile tea at night can be a nice part of that ritual." Chamomile has been used traditionally for treatment of insomnia and anxiety, and it also has anti-inflammatory and anti-bacterial properties. As with many herbal remedies, the science behind it is lacking, but it's definitely worth a try. (You can pick up a box in a really pretty, resuable tin on Amazon for $8.)
Is there anything reverse psychology isn’t good for? In this case, it may alleviate excessive sleep anxiety. A small study conducted at the University of Glasgow found that sleep-onset insomniacs who were instructed to lay in bed and try to stay awake with their eyes open fell asleep quicker than participants told to fall asleep without this “paradoxical intention” (PI). Participants in the PI group fell asleep easier and showed less sleep performance anxiety.
People with insomnia struggle to get a good night's rest and wonder how to sleep better They may be plagued by trouble falling asleep, unwelcome awakenings during the night, or fitful sleep — alone or in combination. They may feel drowsy during the day and yet be unable to nap. Insomnia can leave a person feeling anxious and irritable or forgetful and unable to concentrate.
Over the years, I’ve written in-depth about some of the best-studied, most effective natural sleep aids. As we head into the new year with a focus on prioritizing sleep, I thought I’d share a quick review of some of my top suggestions for natural sleep therapies. These are the supplements that I most often discuss with my patients, and in some cases use for myself and my family.
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.
