You may not even know it's happening, but if kicking and twitching of your legs is disrupting or interfering with your sleep, you will no doubt feel very tired the next day. And if you are tired, you will not be able to perform at your optimum level. If you experience the problem while trying to fall asleep or it wakes you up, you might describe it as tingling, "creepy-crawly" sensations or burning feelings in the feet, calves, thighs or arms. You will have an overwhelming need to move or rub those areas until the feelings stop. Restless Leg Syndrome (RLS) may not be the most serious sleep disorder in terms of health consequences, but it sure can cause a lot of misery for people trying to get a good night's sleep.

Anthropologists will tell you that the way we sleep is a cultural thing. From hammocks in the Amazon to tatami mats in Japanese homes, sleep positions and beds vary from country to country. Sleep research has shown that perhaps our American way of sleeping on a flat surface may not always be the best for our health. In fact, studies have shown that sleeping with the head raised is beneficial for sleep apnea and a host of other health problems.

Aside from inheriting great genes, good health is a direct result of: What you eat, how you exercise, and how you sleep.
