What causes dizziness while running?

Modern people are paying more and more attention to their physical health, and running is a low-carbon and cost-saving sport. However, many people who do not exercise much will feel dizzy when running, especially some middle-aged people. What caused that willingness?

After strenuous running, your blood vessels will dilate extra, and dizziness may occur. Therefore, we will experience dizziness caused by orthostatic hypotension after finishing running training. For most people, this dizziness will disappear quickly after the body adapts and adjusts.

4. Stop suddenly after running

It is normal to feel dizzy when you get off the treadmill after running.
