Dizziness after anger is caused by increased blood pressure and excessive carbon dioxide excretion, resulting in respiratory alkalosis. Sympathetic excitement when a person is angry will lead to symptoms such as increased blood pressure, increased heart rate, and faster breathing, which will manifest as dizziness when blood pressure is mildly elevated. When breathing is accelerated, excessive carbon dioxide will be expelled from the body and more oxygen will be inhaled, but excessive carbon dioxide emission will lead to a state of respiratory alkalosis, which can lead to dizziness, facial numbness, numbness of the limbs, twitching of the limbs and other symptoms. This situation should be calmed down, usually should develop a good character, avoid emotional excitement. If dizziness occurs it is recommended to find a place to rest first, you can relax and breathe, or you can breathe into a paper bag to re-inhale the exhaled carbon dioxide to correct the symptoms of respiratory alkalosis.
