The Little-Known Health Benefits of Deep Sleep

The different phases of sleep and how this component of health works to restore and reenergize us remain largely mysterious. But studies find that deep sleep has a number of surprising benefits for your health and your everyday performance - making a strong case for sleep-easy solutions.

Deep sleep is also known as Rapid Eye Movement (REM) sleep, and it is a greatly important component of the sleeping pattern. REM is the fifth stage of sleep, generally occurring about 60 to 90 minutes after you go to sleep.

In this phase, your eyes rapidly tremble under your closed lids, while respiration becomes irregular and shorter. Your heart beats faster and your blood pressure rises, while your brain becomes neatly as alive as when you are awake. Muscles, too, become paralyzed in a state known as atonia, preventing you from acting out your dreams.

One major benefit of deep sleep or the REM phase is its massive influence on memory. REM is so crucial because it's a time for your memory-linked brain areas to become alert. It has even been hypothesized that while in deep sleep, dreams emerge as the product of the data absorbed throughout the day, analyzed and then filed away.

REM sleep appears in research to improve upon our kind of memory that learns how to do things. Daytime naps or non-REM sleep, in comparison, seems to enhance so-called declarative or easily remembered memory. This shows that being in deep seep is entering a kind of virtual reality, where dreams or parts of them can maintain a certain significance that is not easily surfacing in a state of wakefulness.

Another benefit of deep sleep is energy restoration. When you don't get enough of it, you can almost be assured that you will feel like you have not had a shuteye at all. This restorative form of sleep is controlled by your circadian clock or a natural mechanism telling you it's time to go to sleep or wake up.

This is why it is vital to sleep according to your own circadian clock, which is greatly set by the natural hormone melatonin. Without this body clock, sleep periods would not provide their utmost benefits, and you will be left in want of fully restorative sleep.

Make no mistake about it, though: all phases of sleep play a role in restoring your body, much like batteries need full recharging. This is why the recommended amount of sleep typically varies but is usually between six to nine hours a night, giving your body the time and rest it needs to get through all the sleep phases.

Lack of deep sleep spells trouble particularly on your memory, motor skills and concentration. Chronic sleep deprivation, too, can negatively affect your nervous and immune systems, to name a few. Thus you should pay good attention to the amount and quality of your sleep, including seeking ways on how to cure insomnia and using natural sleep aids for best results.

As a foundational part of optimal health, sleep matters - and so does deep or REM sleep.
