What is the relationship between sweating and the heart?

There is no direct relationship between sweating and the heart, but certain heart conditions can be accompanied by sweating. There are multiple causes of sweating, including exercise, hyperthyroidism, angina pectoris, emotional stress, calcium deficiency, and more. Specific explanations are as follows:

1. Exercise: Intense exercise leads to increased sweating. The body's own temperature regulation mechanism dissipates excess heat through sweating to maintain normal body temperature.

2. Hyperthyroidism: One of the clinical manifestations of hyperthyroidism is excessive sweating. A thyroid function test can be conducted at the hospital for a definitive diagnosis.

3. Angina Pectoris: During an angina attack, patients may experience excessive sweating due to pain in the precordium, with particularly high sweating on the forehead.

4. Emotional Stress: When stimulated or frightened, emotions become tense and excited, causing the sympathetic nervous system to become activated, leading to sweating.

5. Calcium Deficiency: Patients with calcium deficiency may also experience excessive sweating. Calcium supplements and vitamin D can be taken orally as prescribed by a doctor to replenish calcium, and more time should be spent in the sunshine daily.
