Summarized below are three new studies that help us understand more about sleep. Summaries below are draw from WebMed (www.webmd.com) research summaries and articles on sleep written by Dr. Micheal Breus, PhD, ABSM.
1. The National Science foundation interviewed 1000 adults (ages 23-60) to determine the effects of exercise on sleep. Respondents reported their physical activity for the week (vigorous, moderate, light, and no activity). All respondents reported the same amount of sleep, but the more people exercised in the day time, the higher the quality of sleep (i.e. they felt more rested and refreshed when waking). 61% of the non-exercisers reported bad sleep (e.g. difficulty falling and staying asleep, difficulty falling back asleep, sleeping too little), and were more likely to report feeling sleepy during the day. But perhaps most significant is that even those who only reported light exercise (e.g. 10 minute walk a day), reported better sleep than those who did no exercise. Participants who exercised more reported improved sleep regardless of when during they day they exercised.
2. A new study conducted by the University of California Berkeley suggests poor sleep may contribute to the lack of appreciation in couples. Researchers studied 60 heterosexual couples between ages 18 and 56, asking them to record amount of sleep and their feelings of gratitude. Results suggest that people tend to feel less appreciated by their partners if they slept poorly. In fact, when just one member of the couple slept poorly, both partners are negatively effected emotionally and have a lower level of appreciation felt in the relationship. This may explain why more couples are sleeping separately (25% and rising). Poor or insufficient sleep leads to crankiness and less ability to adapt to changes. So it's no wonder that we are less appreciative when we have slept poorly.
3. Modest sleep improvement appears to increase tolerance for pain. Researchers at the North Shore-Long Island Jewish Sleep Disorders Center extended the sleep of half the participants (ages 21-35) to 10 hours a night and then tested both groups for pain tolerance (how long it took them to remove hands from a heat source). The extended sleep group had a 25% increase in pain tolerance, the equivalent of taking a pain killer. Findings are found in the December 2012 issue of Sleep. Although this small study cannot conclude that increased sleep causes higher pain tolerance, it does suggest that those
expecting to have surgery or suffering from chronic pain would benefit from increased sleep.
So what can we conclude?
1. Arrange your schedule so that you can get 7-10 hours of sleep each night.
2. If you, your partner, boss, or best friend is experiencing sleep problems, get or encourage them to get some help improving their sleep habits.
3. Exercise everyday, even on busy days.
4. If you're experiencing chronic pain, consider other causes of pain beyond the initial diagnosis such as sleeping more.
