The weather is hot, why is it dizzy?

I don't know whether you are overweight or not, and whether your blood pressure and blood lipid are normal.

Is dizziness a symptom from air-conditioned room (low temperature environment) to outdoor (high temperature environment)? The above dizziness symptoms are caused by the expansion of capillaries on the body surface from low temperature environment to high temperature environment, which leads to the increase of blood circulation and the decrease of relative blood supply to cerebral vessels, which leads to temporary ischemia of cerebral vessels and temporary hypoxia of the brain and dizziness.

It is recommended to measure blood pressure and blood lipid, if it is high in fat. It is recommended to eat less and exercise more (moderate weight loss) and eat less greasy food.
