What happens if you don't sleep

We're all looking to try and get to most out of our day, squeezing in an extra hour here and there. But there is nothing more critical to your health and well being then getting the right amount of sleep on a consistent basis. James E. Gangwisch, an assistant Professor at Columbia University and sleep expert, reveals how consistent sleep deprivation affects your health.

Help. My father is having a trouble sleeping for 6 months now. He lost weight, and he is not that cheerful person like he was. He also starting to get more nervous and his heart starts to beat faster when he gets shock. For example, when we drop something, it would make him shock. This week, he fainted and confined to hospital. He was able to sleep while he was in the hospital. But when he discharged, he started to having a trouble to sleep again.

What can we do? I notice that he gets weaker and weaker and it really bothers me.

It's 4AM and if I sleep I'll be late AF since I have to leave for school later at around 5:30. :(

PS. I stayed up to finish my homework lol
