The body logic
Cooling the body is work. Blood moves toward the skin, sweat evaporates, fluid drops, and the heart may work harder. If cooling cannot keep up, dizziness and weakness can appear.
Quick answer
why does heat make me dizzy and weak
Heat can make you dizzy or weak by causing sweating, dehydration, salt loss, lower blood pressure, faster heartbeat, and overheating. Confusion, fainting, seizure, chest pain, severe weakness, or no improvement needs urgent care.
