Why Does My Heart Beat Faster While Sleeping?

At night, which is a time for deep sleep, a sudden increase in heart rate can not only affect sleep but also cause feelings of panic and worry about potential health issues. A rapid heartbeat during sleep is not a good symptom and may be related to conditions such as insufficient blood supply, coronary heart disease, arrhythmia, and autonomic nervous system disorders. It is recommended to seek medical attention immediately to address the underlying cause and prevent the recurrence of this phenomenon.

Causes of Rapid Heartbeat During Sleep

1. Insufficient Blood Supply to the Cardiovascular System: When the cardiovascular system does not receive sufficient blood supply, it can lead to a noticeable increase in heart rate upon waking in the middle of the night, accompanied by palpitations and chest tightness. Individuals in this situation should prioritize rest, avoid excessive fatigue, maintain a balance between work and rest, avoid staying up late, and adhere to a diet that is light and low in salt, avoiding greasy foods.

2. Coronary Heart Disease: Coronary heart disease can lead to psychological imbalance and accelerated heart rate. If the heart rate and palpitations are severe upon waking in the middle of the night, it may indicate the presence of coronary heart disease. In such cases, it is crucial to seek treatment at a reputable hospital, undergo a comprehensive physical examination, and communicate closely with doctors. Delaying treatment can lead to more severe health issues. Additionally, maintaining a healthy lifestyle, avoiding greasy foods, and consuming foods that promote vascular health, such as black fungus and onions, is recommended.

3. Autonomic Nervous System Disorders: Disorders of the autonomic nervous system can lead to dysfunction of various organs and manifest as accelerated heart rate and leg weakness. People experiencing these symptoms should engage in gentle exercises such as swimming, playing sports, or running. Those with poor physical fitness are particularly prone to autonomic nervous system disorders, so appropriate exercise is essential for regulation.

4. Arrhythmia: Arrhythmia can accelerate the heart rate, disrupting sleep and leading to severe palpitations upon waking in the middle of the night. When the heart rate becomes excessively abnormal, it is essential to seek medical attention promptly and undergo an electrocardiogram to rule out arrhythmia as the cause. It is also important to maintain a calm and peaceful mindset, avoid excessive emotional excitement, and ensure sufficient sleep.

Rapid heartbeat during sleep may be caused by the above four reasons. It is crucial to seek medical attention promptly to rule out potential health issues and avoid delays. Maintaining a positive and optimistic attitude, avoiding excessive psychological burden, and engaging in appropriate physical exercise to improve physical fitness are also essential. Additionally, it is recommended to avoid watching stimulating programs or eating spicy and stimulating foods before bedtime, and to eat a moderate dinner to avoid overeating.
