Physiology & Medicine / How does blindness affect the body clock?
« on: 29/07/2008 21:17:00 »
Melatonin is a natural chemical that is released from a gland in the middle of the brain. This chemical controls our waking and sleeping times(body clock). Blindness causes the brain to forget the time of day wether its day or night. Melatonin is released at its peak at night and lowest at mid day. By the brain being unable to register this, melatonin is released at randoms time, this therefore disrupts your bodclock.
