Tip # 14
Did you know that a lack of sleep can affect our interpretation of events?
Sleep-deprived people seem to be especially prone to poor judgment when it comes to assessing what lack of sleep is doing to them. In our increasingly fast-paced world, functioning on less sleep has become a kind of badge of honor. But sleep specialists say if you think you’re doing fine on less sleep, you’re probably wrong. And if you work in a profession where it’s important to be able to judge your level of functioning, this can be a big problem. “Studies show that over time, people who are getting six hours of sleep, instead of seven or eight, begin to feel that they’ve adapted to that sleep deprivation — they’ve gotten used to it,” Gehrman says. “But if you look at how they actually do on tests of mental alertness and performance, they continue to go downhill. So there’s a point in sleep deprivation when we lose touch with how impaired we are.” (Web M.D)

About 40 percent of the body consists of muscles that are used for movement, work, and play (Fahey, Insel, and Roth 2003). When your muscles are strong, you can confidently lift, reach, move, push, and pull without much thought. Strong muscles reduce the possibility of injuries, improve body composition, provide a sense of confidence, and allow you to recover more quickly from physical activities (ACSM 2001). (Human Kinetics)
