Sleep Cycles

Most people never think about sleep cycles until they begin feeling the impact of not getting an adequate amount of sleep. In fact, there are some people who only know of REM sleep because they hear about it in movies, read about it in books, or watch shows on  television that mention it. However, they have little knowledge of what it means or how different sleep cycles impact their mental and physical health and well-being.

Excessive alcohol use can wreak havoc on your sleeping patterns for a number of reasons. While some people may believe that alcohol aids in being able to sleep, it actually creates the opposite effect and can seriously disturb your sleeping patterns.

Non REM Sleep

Sleep is composed of natural sleep cycles of brain activity, and is made up of two basic phases with individual stages within. These include rapid eye movement (REM) sleep and non-rapid eye movement (NREM) sleep.

What is Non REM Sleep?

Non REM sleep occurs during the first four sleep phases, and before REM sleep, which is the final stage before the sleep cycle repeats itself. On average each stage lasts from five to 15 minutes. A typical night’s sleep is comprised of 75% non-REM sleep and 25% REM sleep.

REM Sleep

There are 5 distinct sleep stages, with REM sleep being one of them. Most people fall into the REM sleep stage nightly, and many experience it four or five times each night.

What is REM Sleep?

REM stands for rapid eye movement, and is characterized by random, fast-darting movements of the eyes. While the amount of time you spend in REM sleep varies depending on your age, most adults spend up to 25 percent of their total sleep time in REM sleep. On the other hand, newborns spend more than 75 percent of their sleep time in REM sleep.
