What Are Common Insomnia Side Effects?
Insomnia side effects, even from occasional insomnia, are usually immediate and profound. The most common insomnia side effects include fatigue, low energy levels, difficulty concentrating, and mood changes such as irritability, anxiety, or depression. Other side effects from insomnia affect the body, and may cause weight gain or increased levels of stress hormones such as cortisol in the body, which can potentially lead to heart disease.
