Extreme heat can trigger headaches by causing dehydration, heat stress, and changes in blood flow. High temperatures make the body lose fluids and electrolytes through sweating, which may lead to dehydration-related headaches and fatigue. Heat can also dilate blood vessels and increase body temperature, contributing to discomfort and dizziness.
In severe cases, prolonged exposure may increase the risk of Heat Exhaustion, which often includes headache as an early symptom. Staying hydrated, avoiding direct sunlight during peak hours, wearing light clothing, and resting in cool environments can help prevent heat-related headaches and protect overall health.
