Can anxiety cause an increased heart rate?

Anxiety disorder may cause an increased heart rate, one of its common physical symptoms, resulting from nervous and endocrine system disturbances triggered by anxiety. It may also be accompanied by other physical discomforts. If rapid heartbeat occurs frequently, lasts for prolonged periods, or is accompanied by symptoms such as chest pain or dizziness, prompt medical attention is recommended.

During an anxiety attack, the sympathetic nervous system becomes abnormally activated, prompting the excessive release of hormones such as adrenaline and cortisol. These substances directly affect the heart, increasing heart rate and enhancing myocardial contractility, leading to a racing heartbeat, palpitations, or a pounding sensation in the chest.

This elevated heart rate typically coincides with emotional fluctuations—symptoms worsen during heightened anxiety and gradually subside as emotions stabilize. It is often accompanied by other physical symptoms of anxiety, such as chest tightness, shortness of breath, sweating, and trembling. Although not caused by structural heart disease, it can significantly impact quality of life.

In daily life, maintaining a regular sleep schedule and avoiding late nights and excessive fatigue are important. Practicing deep breathing, meditation, and other relaxation techniques, engaging in mild physical activities such as walking or yoga, and reducing intake of caffeine and spicy foods can help alleviate anxiety-induced rapid heartbeat.
