We require on average 8 hours of sleep a night. But that average number is deceptive as different individuals require different amounts of sleep. If you feel rested and alert you probably had enough sleep regardless of the number of hours. Sleep also varies with age. As we mature we need less sleep but as we get older we require more sleep. Indeed, over half of those over the age of 65 experience disturbed sleep.
Modern society has become more around-the-clock and more complex producing considerable pressure and stress on the individual. The advent of the internet and smart phones has exacerbated the problem. The produced stress can lead to impaired sleep. Indeed, it is estimated that over half of Americans sleep too little due to stress. Not having a good night’s sleep has adverse effects upon the individual’s health, well-being, and happiness. Yet over 70 million Americans suffer from disorders of sleep and about half of these have a chronic disorder. These disorders include insomnia, sleep apnea, narcolepsy, and restless leg syndrome.
Beyond problems with sleep disorders, simply not getting enough sleep impairs behavior during wakefulness including constant yawning, the tendency to doze off when not active for a while; for example, when watching television, grogginess when waking in the morning, sleepy grogginess experienced all day long, poor concentration, and mood changes with the individual becoming more irritable. Obviously, people in modern society need to get more and better quality sleep. About 4% of Americans revert to sleeping pills. But, these do not always produce high quality sleep and can have problematic side effects. So, there is a need to find better methods to improve sleep even in the face of modern stressors.
Contemplative practices have been reported to improve sleep amount and quality and help with insomnia (see http://contemplative-studies.org/wp/index.php/category/research-news/sleep/). In today’s Research News article “The Effects of Mind-Body Interventions on Sleep Quality: A Systematic Review”

Neuendorf and colleagues review the literature on the effectiveness of mind-body practices for the improvement of sleep. They reviewed findings for biofeedback, guided imagery, hypnotherapy, meditation, relaxation, and yoga, qi gong, and tai chi effects on sleep. They found overall mixed results. But, hypnotherapy, meditation, yoga, and qi gong and tai chi appeared to be somewhat effective in promoting sleep.
How do these mind-body practices improve sleep? One obvious possible mechanism is by stress reduction. Mind-body practices have been shown to reduce both physiological and psychological responses to stress (see http://contemplative-studies.org/wp/index.php/category/research-news/stress/) and stress is known to interfere with sleep. Another possibility is that these practices are known to reduce mind wandering and intrusive thoughts which are often a problem in trying to go to sleep. Additionally, these practices are known to improve emotion regulation (see http://contemplative-studies.org/wp/index.php/category/research-news/emotions/), and powerful emotions can interfere with sleep. Regardless, of the mechanism, these practices are inexpensive and safe, having very few adverse effects, and have many other beneficial effects in addition to improving sleep. There is not much to lose and potentially a great deal to gain.
So, engage in mind-body practices and sleep better mindfully.
“I’ve always envied people who sleep easily. Their brains must be cleaner, the floorboards of the skull well swept, all the little monsters closed up in a steamer trunk at the foot of the bed.” ― David Benioff
