There are many reasons we need to sleep.
The main is if we don't sleep we can become irratible, unfocused and find it difficult to do daily tasks

Sleep is a requirement from your body to function. Your physical body has to rest and your mind has to rest. The body works in overdrive while you are awake and when you go into sleep, receptors in your brain allow certain tasks to happen while you sleep. Ie. certain chemicals are released to fight cancer when you sleep.
