Can insomnia cause palpitations or anxiety?

Insomnia can indeed potentially cause symptoms of palpitations and a feeling of panic. During insomnia, due to insufficient sleep duration or poor sleep quality, the body is unable to adequately rest and recover, which may lead to dysfunction of the autonomic nervous system, subsequently triggering discomforts such as palpitations and panic. Specifically, insomnia may cause increased sympathetic nervous system activity, resulting in an elevated heart rate and enhanced myocardial contractility, thus producing the sensation of palpitations. Emotional factors such as anxiety and tension caused by insomnia may also exacerbate symptoms of palpitations and panic. For individuals who frequently experience insomnia, paying attention to heart health and promptly adjusting sleep habits to ensure sufficient sleep duration and quality are important measures for preventing and alleviating symptoms of palpitations and panic. If necessary, timely medical consultation and professional diagnosis and treatment should also be sought.
