What should I do if I experience palpitations and hand tremors after drinking coffee?

Coffee has a stimulating effect on the human brain and nervous system. Palpitations and hand tremors after coffee consumption are likely due to excessive nervous system stimulation. Temporary bed rest, maintaining emotional stability, and avoiding excessive anxiety are recommended. Drinking some sugar water or plain boiled water may help accelerate caffeine metabolism. If necessary, an electrocardiogram (ECG) should be performed; if arrhythmia or other abnormalities are detected, medications such as propranolol (Inderal) or Wenxin Keli may be prescribed for treatment.
