By sleeping longer and more deeply we can protect our health. But how do you do this if you suffer from insomnia? Sleep therapists long ago developed “sleep hygiene,” also known as good sleep habits. I’ve adapted the rules of sleep hygiene into the following eight simple steps to help you get better ZZZZ’s:
(1) Sleep in a cooler room. As night falls and body temperature drops, the brain slows down and drowsiness sets in. Turning down the thermostat can facilitate that.
(2) Make your room completely dark. Cover up all LED lights (even tiny ones) on alarm clocks and any other electronic equipment. If it’s still not dark enough, buy some classic eyeshades available at most drugstores. Darkness causes the body to produce more melatonin, the hormone that signals the body to sleep. Even small amounts of light decrease melatonin production and signal the body to awaken.
(3) Don’t fall asleep to the TV or iPad screen (too stimulating); even better, move all gadgets out of the bedroom.
(4) Go to bed and wake up around the same time every day, even on weekends.
(5) Avoid alcohol and heavy meals at least 3 hours before bedtime.
(6) Exercise regularly but not within 2 hours of retiring. It may take 2-4 months of regular exercise for you to start sleeping longer and more deeply, and better sleep will then help your exercise routines. (See “How Exercise Can Help Us Sleep Better”, NYTimes, 8/21/13.)
(7) Establish a pre-sleep ritual such as a bath, meditation or reading.
(8) Avoid sleeping pills. The so-called Z drugs (Ambien, Sonata and Lunesta) only increase total sleep time by 28 minutes compared to a placebo, according to a 2005 NIH study. They may be habit-forming, cause next-day drowsiness and memory loss, and mask the fact that your underlying cause of sleeplessness could be depression, anxiey or simply poor sleep hygiene.
Of course, acupuncture is well-known as a beneficial treatment for short- and long-term insomnia, and Chinese herbs such as suan zao ren (Zizyphus) are natural and safe alternatives to prescription sleeping pills.
