One of the major difficulties is that many physicians will not admit that they have a problem. There are many types of treatments for acute episodes of stress. I have found rest, exercise, and diet to be the best treatment protocol for myself and many of my patients. Researchers have difficulty agreeing to the amount and duration required to have us function at optimum levels. Most research involving rest is done in the field of sleep studies.
Insomnia is frequently stress related.
When we sleep is very important. Most of our activity takes place according to a circadian cycle, slightly longer than 24 hours. Sleep normally occurs during the time of reduced physiological functioning. REM sleep peaks during the early morning hours when our body temperature is at its lowest. If we work late hours and stay up half the night worrying, we are likely to sleep but miss some of the rest needed from REM sleep.
