Sleep is an essential process I believe. In nature we see it. Everything in the world used to sleeping. BUT it differs for each organism. Humans, I dont know how much. The eight hour sleep thing must be industrial made. Humans may not need much sleep. Or some may need more as they gain halth or recover something. So it depends. If you feel to sleep only less then its fine. But try to get some sleep when you feel like you need it. Our body shows signs always. Listening to it and understanding it is necessary.
