Sleep
Sleep is a normal, easily reversible, recurrent, and spontaneous state of less efficient responsiveness to external stimulation. Sleep usually requires the presence of flaccid or relaxed skeletal muscles, and the absence of the overt, goal directed behavior of which the waking organism is capable. How much sleep does a person need?
For adults, anything between 6, and 8 hours of sleep as a nightly average is usual seven and half hour. Older persons sometimes require less sleep. Children need about 12 hours of sleep. Babies have both deep and light sleep cycle. In each sleep cycle, there are 60 minutes of light sleep, 60 to 90 minutes of deep sleep, and another 30 minutes of light sleep. At the end of this cycle, the baby is semi-alert and can be wakened easily. There are different kinds of sleep that has been long recognized, in everyday discourse there is talk of “good” sleep or “poor” sleep, of “light” sleep, and “deep” sleep. You can help to improve your nightly sleep, increase your energy, and quality rest by performing yoga, Pilates, tai chi exercises, and hypnosis, or listening to music, which puts you into a deep trance, and into a deep sleep. To improve the quality of your sleep you should, avoid large meals just before bedtime (minimum four hours). Small snacks are not a problem, but large meals keep the digestive system active, and can disrupt sleep. Avoid heavy exercise within two to three hours of bedtime. Heavy exercise can raise body temperature, and cause difficulty falling asleep at bedtime. Avoid nicotine, caffeine, alcohol, or other stimulants within four hours of bedtime.
