There are several reasons why dizziness improves after exercise: 1. In patients with low blood pressure, dizziness is caused by low blood pressure, and appropriate exercise or a lot of exercise will cause blood pressure to rise. After the blood pressure rises, the symptoms of dizziness will improve. 2, dizziness improves after exercise, mostly in patients with emotional disorders, such as anxiety and depression, when the activity can promote the release of neurotransmitters in the brain, such as dopamine, which can also cause sympathetic excitation, sweating, and then an increase in metabolism, which then increases with the release of neurotransmitters in the brain and the excitability of the sympathetic nerves. The patient’s mood is more pleasant, and the dizziness is relieved after the sweating exercise, which is also related to the improvement of concentration.
