Introduction

Headaches and dizziness after running may be caused by physiological factors, or by insufficient cerebral blood supply, brain hypoxia, and other reasons. If a person who has not exercised for a long time suddenly engages in intense physical activity, it may lead to cerebral blood vessel dilation, resulting in headaches and dizziness. Usually, no special treatment is required. Regular participation in recreational activities can help improve immunity.

Headaches and dizziness after running may be caused by physiological factors, or may result from insufficient cerebral blood supply, brain hypoxia, and other reasons. The specific details are as follows:

I. Physiological Factors

If a person has not exercised for a long time and suddenly engages in intense physical activity, it may lead to cerebral vasodilation, resulting in headaches and dizziness. Usually, no special treatment is required. Regular participation in appropriate recreational activities can help improve immunity.

II. Pathological Factors

1. Insufficient Cerebral Blood Supply

During running, significant energy is consumed and blood flow shifts toward the limbs, leading to inadequate perfusion of brain tissue, which may cause symptoms such as dizziness and nausea. Treatment may include medications such as flunarizine hydrochloride capsules or betahistine hydrochloride tablets, taken as directed by a physician.

2. Cerebral Hypoxia

This generally refers to a condition where oxygen supply or utilization fails to meet the minimum level required for brain metabolism, leading to varying degrees of brain dysfunction. Symptoms may include slowed reaction times and excessive sleepiness. Treatment options under medical guidance may include Naoluotong capsules or Ginkgo biloba leaf tablets.

In addition to the above causes, headaches and dizziness could also be due to conditions such as sinusitis, subarachnoid hemorrhage, or cerebral infarction. It is important to get adequate rest, avoid overexertion and strenuous exercise, and seek prompt medical attention if symptoms occur.
