why sleeping is important
Sleeping is important, The human body is functioning 24 hours a day. The
cerebral cortex is functioning like muscle nerves every second. The blood is
also flowing. The heart beats 100000 times a day. Our body needs rest while
doing all this work. The human body needs rest just as much as a machine needs
rest. The blood is purified only when you sleep. Sleep is needed to repair and
regenerate dead tissue to grow in our bodies. So sleep is very important for
you to be healthy.
