What causes frequent palpitations and hand tremors?

Generally, frequent palpitations and hand tremors may be caused by factors such as emotional stress, excessive caffeine intake, anemia, arrhythmia, or hyperthyroidism. If discomfort occurs, it is recommended to seek medical attention promptly. Specific analyses are as follows:

1. Emotional Stress

When experiencing emotional stress, the sympathetic nervous system becomes activated, triggering a series of physiological responses including increased heart rate, elevated blood pressure, and muscle tension. This can lead to recurrent palpitations and hand tremors, often accompanied by symptoms such as rapid breathing and dizziness. It is recommended to learn relaxation techniques such as deep breathing and progressive muscle relaxation, which can help alleviate stress.

2. Excessive Caffeine Intake

Consuming too much caffeine—such as from drinking large amounts of coffee, tea, or energy drinks—may cause frequent palpitations and hand tremors, usually accompanied by symptoms like anxiety and headaches. It is advisable to reduce caffeine intake and avoid consuming caffeinated beverages in the evening.

3. Anemia

Anemia results from insufficient quantity or quality of red blood cells in the blood. Due to reduced oxygen-carrying capacity, the body's tissues and organs cannot receive adequate oxygen, leading to persistent palpitations and hand tremors, along with symptoms such as dizziness and fatigue. It is recommended to follow medical advice and use medications such as ferrous sulfate tablets, vitamin C tablets, and folic acid tablets for treatment.

4. Arrhythmia

Long-term irregular作息 (daily routines) may lead to arrhythmia. Arrhythmia disrupts the heart’s normal pumping function and stimulates the sympathetic nervous system, resulting in frequent palpitations and hand tremors, possibly accompanied by shortness of breath or fainting. It is recommended to take medications such as enteric-coated aspirin tablets, simvastatin capsules, and metoprolol succinate sustained-release tablets under medical supervision to regulate heart rhythm.

5. Hyperthyroidism

Hyperthyroidism refers to the overproduction of thyroid hormones by the thyroid gland, which accelerates the body's metabolism and leads to persistent palpitations and hand tremors. Common accompanying symptoms include excessive sweating and bulging eyes. It is recommended to follow medical guidance and use medications such as methimazole tablets, propylthiouracil tablets, and levothyroxine sodium tablets for treatment.

In daily diet, it is advisable to avoid spicy and raw cold foods to prevent bodily discomfort.
