Just like maintaining a healthy diet and exercising regularly, getting quality deep sleep is essential for your optimum health. Keeping you energetic and also for building your body's immune system against infections and chronic illnesses.
So what then is deep sleep?
To put it simply, deep sleep is a phase when you will be very difficult to be awaken by external factors because of near complete disengagement from the environment.
On average a person should get about 7 to 9 hours of quality sleep daily.
During deep sleep body refreshes and rejuvenates. Kidneys cleanse blood, organs detox and wounds heal. Cells and muscle tissues repair, replace and build up. Brain relaxes and memory consolidates.
Here's what happens when you are sleep deprived:
- Weight gain: Our human growth hormone is a profound anabolic (process of tissue building) hormone. It is produced by a small pituitary gland that is located at the base of the skull. Human growth hormone is released in pulses during deep sleep, and any interruption at this stage abruptly stop its release. Growth hormone helps maintain some bodily functions like tissue repair, muscle growth and metabolism (the rate at which our body burns kilojoules for energy). So, lack of sleep slows down your metabolism and makes you gain weight.
- Heatiness: Lack of sleep disrupts regulation of body heat and causes certain illnesses like ; Fever, Constipation, Sore Throat, Pimples and Acnes, Mouth Ulcers and Indigestion.
- Depressed immune system: that will lead to many illnesses like throat infection,cold and flu.
And long term effect like heart disease. - Slows down brain function: like alertness, reactive responses and memory loss. People who don't sleep well at night tend to be more forgetful, short temper and irritable than those who sleep soundly.
And long term effect like dementia.
Research has shown that people who exercise regularly tend to sleep better.
Keeping to a regular sleeping schedule and having a more conducive surroundings to rest does help.
