The Relationship Between Sound Sleep And Good Health

Remember the last time you woke up in the morning, fresh like a flower and brimming with energy? Yes, sound sleep and good health are closely interrelated and several researchers have also established this fact. To keep an array of diseases, some of them even life threatening, you need 6 to 8 hours of sound sleep.

What is sound sleep?

In the context of sleep and good health, it is important to differentiate between ‘sleep’ and ‘sound sleep’. Merely tossing around in the bed and unable to move into deep sleep is the experience of most of us today. ‘Sound sleep’ is defined as a state of semi-consciousness where the door bell or the ringtone from a phone does not wake you up instantly. You detach yourself from the surroundings to an extent where the central nervous system recognizes that your body is completely relaxed.

Repairs and maintenance

A 2013 study by the University College of London and University of Surrey has established that sleep as a biological function has been designed to enable important repair and maintenance tasks for the brain cells which are termed as neurons.


Memory is another area where sound sleep and good health are inter-related. Hippocampus is the region of the brain that stores new memories.  Sleep deprivation, even for a night impacts the ability to store and recall new information significantly. In sleep deprived people, new information may be stored in other regions of the brain. With frequent sleep deprivation, storage capacity of the hippocampus may hit the upper circuit, preventing storage of new information.

Modern day devices

If today’s fast paced lifestyle and craving for junk food were not enough, the modern day electronic devices, particularly, the hand held variants are your biggest enemy when it comes to sleep and good health. The blue light emitted by these devices makes it even more difficult for people to fall asleep further impacting the quality of your sleep.

Rediscovering the values

Perhaps it is time that we start rediscovering the value of sleep and appreciate how it impacts our brain functions. The time we spent in sound sleep is a necessary investment to be smarter, to make quality decisions and enjoy a happier life.

Did you know that the ‘Tube’ or London Underground works at optimal efficiency during day time and goes for extensive maintenance every single night? Human body is more precious than the ‘Tube’.

Similarly, for ages, Casino owners have seen that most risky decisions come from tired gamblers.  The noise, bright lights, and absence of windows are by design so that the gamblers do not get a feel of the time.
