The Science of Sleep: How to Optimize Your Restful Nights

The sad thing is that lack of sleep proved such an important cognitive dysfunction as being legally intoxicated. It doesn't "shut down" the body, it plays a critical role in health, emotional well-being, and cognitive performance. Surprising to most people, maybe, that millions suffer around the world from poor sleep. 

 

Science Behind Sleeping

Sleeping is a very complex biological process in complex stages. These have distinguishing stages and are called sleep cycles. These major classifications of the sleep cycle are called non-REM, besides REM, types of sleep. 

  • Stage 1 (Light Sleep): Once your body starts relaxing with the deceleration of waves inside the brain.

  • Stage 2: A deep stage in which heart rate and body temperature decrease. It is the longest sleep stage.

  • Stage 3 (deep sleep): This is the most restorative stage, needed for physical repair, growth, and immune response.

Most dreaming occurs in REM sleep. The brain is highly active at that time. Another significant feature of REM sleep is the role it has in the consolidation of memories and learning as well as emotional processing. These cycles are normally repeated several times during the night, although the hours of later sleep have the most REM sleep.

Hormones, such as melatonin and cortisol, control sleep. Melatonin, also known as the "sleep hormone," rises during the night enabling sleep. Conversely, cortisol, sometimes called the "stress hormone," rises in the morning hours to get you awake and moving. Any disruption in this hormonal balance, caused by abnormal sleep or stress, can contribute to a sleep disorder.
