The deprivation of sleep sometimes causes headache, but we might know the cause and think it is something else. people that do not get enough sleep always look daisy and always yawning, for example you see people in buses and train nodding and falling asleep. There are also instances where lack of enough sleep cause student to fall asleep in class sleep .
Societies ignorance to sleep causes harm to lives and properties. We should know that the body needs the right amount of sleep to function well. It may seem to some that sleep is a waste of their time, but the truth is that when we have enough sleep it refreshes the body. Students sleeping in class allows for low performance in their grades and future opportunities.
I think that every institution in the United States should have some kind of awareness about sleep deprivation and the danger it could cause a person on and off the job.
