What harm does staying up late have to the heart

Staying up late will cause a lot of harm to the heart. Staying up late will show obvious heart blood supply and oxygen deficiency due to excessive fatigue. The heart will show obvious myocardial ischemia and insufficient blood volume. At this time, it will show chest distress, shortness of breath, palpitations and other clinical symptoms and manifestations. If you stay up late, for example, when you are still engaged in intense work at night, it will cause nervous system dysfunction. When the sympathetic nerve and vagus nerve are out of control, the heart will show symptoms of arrhythmia, frequent ventricular premature beats, arrhythmia, etc., and there will be obvious clinical symptoms and manifestations of palpitations. In addition, staying up late will cause the body to show nervous system dysfunction and endocrine system dysfunction, which is also harmful to the heart.
