Getting up in the morning and having your heart pounding may be due to lack of sleep, low blood sugar and arrhythmia. 1. Lack of sleep: If you fall asleep late the night before because of late night work, insomnia, etc., and are suddenly woken up by the alarm in the morning, your body is not fully rested, and your body functions are not restored, so your heart may skip a beat. 2. Hypoglycemia: when you sleep at night, the body’s metabolism is still running, after a night of metabolism, consuming the blood sugar intake the day before, you may wake up in the morning with hypoglycemia, which leads to the heart jumping in the morning. 3. Arrhythmia: Arrhythmia, including sinus tachycardia, atrial premature beats and ventricular premature beats, can lead to an increase in myocardial oxygen consumption in the morning and the phenomenon of the heart beating in the morning. If you have a racing heart in the morning, you should go to a regular hospital to find out the cause of the problem and choose the right treatment for yourself under the guidance of a professional doctor.
