The link between sleep and anxiety, as discussed by Tuck.com
As I've personally experienced, and what a vast number of people experience, anxiety levels are directly related to sleep. My anxiety increases when I either don't get enough sleep or don't get quality sleep. Similarly, my anxiety can prevent me from falling asleep and staying asleep. In a great article by the staff at tuck.com , the relation between anxiety and sleep is further discussed. Their description of the article reads: "This guide gets at the link between anxiety and sleep and covers several anxiety disorders that interfere with sleep and which can be alleviated with sleep: generalized anxiety disorder (GAD); social anxiety; obsessive-compulsive disorder (OCD); phobias; post-traumatic stress disorder (PTSD); and panic disorder. It offers solutions to the sleep deprived anxiety sufferers, from treatment options, through online forums, tips regarding healthy sleep hygiene and banishing anxious thoughts, to medical associations that can help."
