Caffeine is a xanthine alkaloid compound, and for some people, caffeine intolerance may occur, manifested by sweating, tightness in the chest, and panic attacks.
Caffeine intolerance may be caused by the body’s immune system treating the caffeine substances entering the body as harmful substances and then producing a protective immune response against these substances, which may be related to factors such as sympathetic overexcitation and physical fatigue.
Caffeine usually stimulates the sympathetic nerves, and if a large amount of caffeine is ingested at one time, some caffeine-intolerant people may experience sweating, tightness in the chest, panic attacks, and tremors. In addition, if caffeine is ingested during periods of fatigue, the heart may become overloaded, resulting in increased heart rate, weakness in the arms and legs, as well as nausea and headache.
Caffeine intolerance is characterized by many symptoms. If you experience discomfort, it is recommended that you consult a doctor in a timely manner and receive targeted treatment under the guidance of the doctor.
