Anxiety and insomnia. Most of us have had some unpleasant acquaintance with these two overwhelming afflictions at one time or another.
In her article, Rheyanne Weaver covers different types of anxiety and their symptoms. She describes various ways anxiety can manifest itself and its debilitating effects. And she talks about how the two disorders interact.
She cites the American Sleep Association (ASA), the National Heart, Lung and Blood Institute (NHLBI) and the National Institute of Mental Health (NIMH) as some of her sources.
Anxiety has a dampening effect on the lives of many people, making every day a trial to get through. Pleasure and optimism in life is replaced with fearfulness and worry.
As for insomnia, the NHLBI states that "one in three adults has insomnia sometimes [and] one in 10 adults has chronic insomnia". Lack of sleep can affect our efficiency and effectiveness, and even our mood. These two disorders together can have a debilitating overall effect on our daily lives.
