By putting study participants on a 90-minute day, Bliwise hopes to learn what happens to body temperature differences and cycles when a person's sleep is disrupted. A second study at Emory examines the movements the healthy elderly make while asleep compared to those of a sleeping patient with Parkinson's. Most patients with Parkinson's, a movement disorder, have trouble sleeping. The folk wisdom is that in patients with Parkinson's, the movements disappear in sleep. Management of muscle movement during sleep is important for Parkinson's patients, Bliwise says.
Sleep is indispensable for life.
