Difficulty sleeping, along with restlessness and anxiety, can be signs of stress, sleep disorders, or other underlying health conditions. These symptoms may overlap with several causes, including medical conditions, medication side effects, or lifestyle factors. Because the reasons can vary widely, it is important to consult a qualified doctor for proper evaluation. A doctor can assess your overall health, identify the root cause, and guide safe and effective treatment. Avoiding self-medication is crucial, as only a healthcare professional can determine the right approach for your condition.
