In a typical night, they go back and forth between two sleep phases. In the rapid eye movement phase (REM), the brain is highly active, the eyes move rapidly back and forth, and dreams occur frequently. In the non-REM phase (NREM), there is less brain activity and no eye movement. The deepest sleep, which occurs during the NREM period, is called slow-wave sleep. This delicate cycle is unfortunately sub- ject to disturbances. About one in 10 people suffer from insomnia -- defined as having trouble falling asleep, staying asleep, or waking up too early. Sleep disturbances are strongly related to mental illness. In a large American study, 40 per cent of insomniacs also reported a psychiatric disorder, mainly anxiety and depression. Because exercise has been linked again and again with emo- tional benefits, it is possible that mental health gains associated with exercise may also improve sleep. A few studies suggest that physical activ- ity may be useful in preventing and treating sleep problems: ¢In a 1985 survey of 1,600 Finns, 33 per cent of men and 30 per cent of women rated exercise as the most important sleep-pro- moting factor. As many as 43 per cent of those who increased their exercise over the previous three months reported improved sleep, whereas 30 per cent of those who decreased their exercise over the same pe- tiod reported worsened sleep. Sedentary \ respondents also reported a higher rate of excessive daytime tiredness -- a symptom of inadequate sleep at night. ¢ In 1985, it was reported that the type of physical training can influence both sleep onset and the amount of slow-wave sleep. Aerobic training was associated with an increase in slow-wave sleep, unlike power training, which led to decreases in slow- wave sleep. * Ina 1995 study, healthy but sedentary elders with normal sleep patterns partici- pated in six months of either aerobic exer- cise or stretching and flexibility training. Both groups reported sleeping better at the end of the program. Only the aerobic exer- cise group showed a clear increase in slow- wave sleep, however. * Physical activity may also play a role in consolidating sleep into a single period. Sleep and wakefulness patterns are clearly disrupted when individuals spend their days in complete idleness. Without activity, the prolonged sleep period of about eight hours ends up being replaced by short fragmented sleep bouts. What type of exercise do we need to sleep better? Although there is no definite answer to this question at the present time, it appears that high-intensity exercise has the greatest effect on slow-wave sleep. However, sleep researchers are unsure about how changes in slow-wave sleep related to changes in sleep quality. Until they come up with a precise an- swer, the best approach is to participate in aerobic activity, regularly. z Why is Kick Fit Karate sweeping the country?
