Signs Of Heat Exhaustion & Heat Stroke

Dizziness Or Lightheadedness

Being overheated can cause blood pressure to suddenly drop too low, leading to a feeling of dizziness or lightheadedness. The reason this occurs is due to a chain reaction that results in the brain not having enough blood flowing to it. When you are too hot, your body dilates your blood vessels in a process called vasodilation and sends more blood to your skin, which is why individuals have a red, flush look when they are overheated. This then causes blood to pool into the legs, and since blood will be flowing downward instead of up, the brain doesn't get as much blood flowing to it resulting in the feeling of dizziness or lightheadedness. A person can also faint from the restricted blood flow.
