Anxiety, cortisol and meditation and their effects on insomnia | Matthew Walker
Anxiety has dramatic effects on sleep patterns and often manifests as insomnia, especially in people who are genetically predisposed to anxious behaviors. Two principal forms of insomnia have been identified – difficulty falling asleep versus difficulty staying asleep – and both are related to derangements in the timing of cortisol release via input from the sympathetic nervous system. Cognitive behavioral therapy and meditation are effective strategies for managing stress and may result in improved sleep. In this clip, Dr. Matthew Walker discusses how anxiety affects sleep and identifies ways to manage that stress to improve sleep.
