Sleep is described as the natural state of the body at rest. This type of rest is observed both in humans and animals and deemed necessary for survival.
It is characterized by diminished ability to react to stimuli as opposed to when a person is fully awake. Sleep has been the subject of intense research and study among doctors and scientist but right up until now, there are still many aspects that need to be explained or that we need to learn about it.
For instance, what results when a person does not get enough rest is widely known yet researchers up until now are not yet able to explain what the purpose of sleep is to the human body.
Sleep is falls into two broad classifications, the REM (Rapid Eye Movement) and the NREM (Non Rapid Eye Movement).
Each of these classifications possesses unique sets of associated neurological, physiological and psychological features. In normal adults, the REM sleep comprise between 20 to 25 percent of the total sleep time. This is the period where the most memorable dreaming happens.
Experts maintain that the optimal level of rest for adults is between seven to nine hours. This period presents great benefits in terms of memory, alertness, problem solving and the overall well being of a person. It also reduces the accident risks that are associated with sleep deprivation.
Contrary to popular belief, sleep cannot be recovered nor stored. Hence, a person who failed to get the proper amount of sleep the previous night would find no significant benefit should he decide to sleep twice as long tonight to make up for the deficiency made the previous day.
Slumber debt is the condition that arises when one does not get enough sleep.
This type of sleep deprivation is attributed the cause of mental, emotional as well as physical fatigue. There are numerous disorders that are associated with sleep, chief among which is insomnia or difficulty in falling asleep.
These disorders also include bruxism, narcolepsy and apnea, and others are caused by a host of factors which may include the environment, anxiety and incontinence, and more.
There are four broad categories of treatment that is available for these disorders, namely: medical, behavioral, rehabilitative as well as other somatic treatments.
Sleep disorders treatments can be pricey but I’m sure you will agree that getting the right amount of sleep is actually priceless in grand scheme of things.
