Heat Stroke Headache: Why Home Remedies Are Not Enough

Heat stroke occurs when the body cannot release heat effectively, and brain function can become affected. Headache may occur alongside confusion, unusual behavior, fainting, weakness, hot skin, nausea, or vomiting. It can be difficult to distinguish early heat illness from heat exhaustion; see Heat Exhaustion for comparison. A headache alone does not prove heat stroke, but headache plus altered alertness or severe overheating should be treated as urgent.

Move the person to shade or an air-conditioned place. Remove extra clothing and cool the skin with wet cloths, cool water, fans, or cold packs wrapped in fabric placed near the neck, armpits, and groin. Stay with them and note when symptoms began. Do not give drinks to someone who is confused, drowsy, vomiting, or unable to swallow safely. Do not delay emergency care to try pain medicine or a home remedy. Medical teams may use IV Fluid Therapy when fluids cannot be taken safely or dehydration is severe.

Call emergency services immediately for confusion, collapse, seizure, trouble breathing, severe headache, repeated vomiting, or a very hot body. A measured fever can also signal a serious problem; read about Fever, but do not wait for a thermometer reading before acting. Keep cooling during transport if it can be done safely.

Ask what caused the overheating, whether medicines or illness increased risk, when normal activity is safe, and which warning signs require reassessment.
