The main reason for dizziness is that the head is cold after blowing wind, which may cause cerebral vasoconstriction, which may lead to insufficient local blood and oxygen supply to the brain and can cause dizziness. If you have similar symptoms frequently, it is recommended that you wear a hat or scarf when you go out to avoid the symptoms of dizziness. If the examination suggests the presence of cerebrovascular spasm or insufficient blood supply and oxygen supply to the brain, cerebral arteriosclerosis, you can apply ginkgo biloba to activate blood and nimodipine to improve cerebrovascular spasm under the guidance of physicians. It is recommended to review the cerebrovascular condition regularly and observe the recovery.
