It is fact that we spend around third of our lives (around 25 years) sleeping , sleep is common activity done by every human, animals birds , insects etc.......... It is same as performing useful task , such as eating , reproducing , and raising young , but let's think why its is important??
one research shows that sleep is very important for everybody , we can't live without sleep, research shows that rat live only two to three weeks without sleep but after two to three weeks rats was die due to without sleep. thus many researches show that sleep is very important , so let's we know what happens to our body when we sleep??
