EXERCISE - A CURE FOR INSOMNIA?
Tuesday, December 26th, 2006WHAT IS INSOMNIA?:
The following definitions all apply to the meaning of insomnia: A prolonged and abnormal inability to obtain adequate sleep, chronic inability to fall asleep or remain asleep for a satisfactory length of time, awaking during the night with an inability to fall back asleep, waking too early in the morning.
WHAT CAUSES INSOMNIA?:
There are many factors that can contribute to insomnia, these can include any one or combination of the following:
Stress, alcohol, caffeine, nicotine, eating late at night, stimulant drugs, medication containing stimulants, sleep apnea (abnormal breathing while asleep), asthma, chronic pain, indigestion, frequent urination, environmental noise, anxiety, depression.
HOW MUCH SLEEP DO I NEED?:
Most adults require 7 to 8 hours of sleep a night. While that remains consistent through adulthood, as we enter our elder years our bodies go through sleep cycle changes and may require less hours of sleep per night with an added nap during the day. If you are constantly tired during the day after having had a full night’s sleep, chances are you need to increase the amount of time you spend sleeping. However, one should be careful not to dwell on expectations of “I must get 8 hours of sleep tonight.” Thinking in such a way could exasperate the effect of insomnia.
STEPS YOU CAN TAKE TO COMBAT INSOMNIA:
Benefits of Exercise - Aerobic exercise combined with weight training performed in the morning or early afternoon has been proven to increase deeper stages of sleep. Research also indicates that people who exercise regularly during these times fall asleep faster than those who do not exercise. Exercise causes a rise in body temperature and a subsequent fall in body temperature approximately five to six hours later which can aid to a good night’s sleep. Exercise also works by relieving stress and tension, helps dissolve lactic acid built up in the blood, eases tension, stimulates the brain and major organs, activates endorphins which gives you a sense of well-being, and energizes the nervous system. Exercise is classified as a physical stressor to the body, the brain equalizes this by allowing deeper sleep to repair, refresh, and renew the body.
Avoid Caffeine and Alcohol - Caffeine is a stimulant and can cause the body to stay awake or have trouble falling asleep and staying asleep. Coffee, tea, cola, and chocolate all contain caffeine. Some individuals are highly sensitive to caffeine and have trouble falling asleep after having caffeine ten to twelve hours earlier. Alcohol, while thought to have sedative effects, can make you sleepy initially but can cause you to wake several times during the night.
