The weather is hot and I feel dizzy. Why do I feel dizzy?

I wonder if you are obese and if your blood pressure and blood lipids are normal.

Does dizziness occur when you move from an air-conditioned room (an environment with a low temperature) to an outdoor environment (an environment with a high temperature). The above-mentioned dizziness symptoms are caused by the dilation of capillaries on the body surface from a low temperature environment to a high temperature environment, which causes an increase in blood circulation. The relative blood supply to the brain blood vessels is reduced, resulting in temporary ischemia of the cerebral blood vessels, and temporary hypoxia of the brain causing dizziness.

It is recommended to measure blood pressure and blood lipids, if they are too high or too fat. It is recommended to eat less, exercise more (moderately), and eat less greasy food.
