The article almost reads like a parody! Who would have thought that getting good, restful sleep would enhance cognitive ability and performance? Almost a "duh" statement.
I am however very interested in why we need as much sleep as we do. Certainly a product of evolution/biology but I am constantly amazed how little we know of what happens to our brain when we go comatose for 8 hours a night.
To another species/race it might actually seem frightening. What?! Humans go into a death like state every 24 hours?!
- sosborn 11y ago> To another species/race it might actually seem frightening Not sure about that. Many species do something similar for a longer period of time.
- NeutronBoy 11y agoTo someone from another planet it might - our sleep cycle has somewhat evolved around a day/night cycle, and animals hibernate based on changes in weather.
- grhino 11y agoOne function of sleep may be to clean up waste accumulated while awake. To run the cleaning process while awake may require more active energy consumption and was a way of conserving total energy in our evolutionary past when activity wouldn't be very productive anyways. http://www.nih.gov/news/health/oct2013/ninds-17.htm http://www.nih.gov/news/health/oct2013/ninds-17.htm
