Sleep training for adults prevents depression, study finds

(CNN)Undergoing cognitive behavioral sleep training, which teaches you how to break bad habits in order to prepare your mind and body for a good night's sleep, may help prevent depression in older adults with insomnia, a new clinical trial has found.

"What is exciting about these findings is that they are among the first to demonstrate that treating insomnia with a behavioral strategy, not a pill, can prevent the development of depression in older adults," said sleep specialist Wendy Troxel, a senior behavioral scientist at RAND Corporation, who was not involved in the study.
