Sleep & Health: What’s the connection

Sleep is a natural process and is as essential for achieving Good Health as eating food and drinking water. Human beings spend and dedicate about one-thirds of their life sleeping but there are two important aspects to sleep – one, the quality of sleep and second, quantity or number of hours of sleep. 

What happens physiologically when we sleep?

It is common knowledge that when we sleep our brain is still active and working. Though scientists for years have tried to understand the complex process associated with sleep, generically speaking sleep has two components to it – NREM or non-rapid eye movement and REM or rapid eye movement. 75% of the human sleep is the non-rapid type when the sleep is the deepest and is characterized by electrical patterns inside the brain. It is during this phase of our sleep that our temporary and short-range memories are pushed into lasting storage. This is also the time when the growth hormones of the body that are responsible for cell repair and reproduction are released to the maximum by the brain.

REM sleep is characterized by vibrant and emotional dreams though the NREM phase is also categorized by dreams but those are more concept-based. It is during this phase that the human mind processes the memories and stresses and collates it for future use. However, science still has not been able to prove as to what happens during the REM stage with different theories proposed though none of them have been validated yet.

It has been proven scientifically that lack of proper sleep can lead to plenty of health problems and it is important to have a good sleep pattern for the overall well-being of an individual.
