Redormin – Ze 91019

What is sleep?

Sleep is a natural recurrent state of rest for the body and mind. During sleep the consciousness is completely or partially lost and the responsiveness to external stimuli is decreased. Sleep is vital since it allows the whole organism to recover. During this time growth and the rejuvenation of the immune, nervous, skeletal and muscular systems take place. Meanwhile, the brain is processing memories and information.
