Pain and anxiety can make it very difficult for an individual to have a good night sleep. People who experience pain, stress, anxiety and depression have far more trouble falling asleep and staying asleep. This is largely due to the fact that our bodies are programmed to respond to stress and potential dangers by waking up. Even the smallest of daily stresses can trigger this body response. Caffeine and alcohol, due to the amount of chemicals inside the body, affect both the quantity and quality of sleep.
