The human body is a machine that needs to rest regularly to function. Sleep is a vital mechanism of a person’s life. It is a process using which our body copes up with exhaustion and restores to its full potential. If a person doesn’t sleep for 6-8 hours every day or is sleep-deprived, their body and mind would not function as efficiently as it should. People with irregular sleep are prone to various health problems. Therefore, adequate sleep is extremely important.
