Outdoor events, hot rooms, restrictive clothing, physical exertion, and prolonged scenes can all contribute to overheating. Early symptoms of heat exhaustion can include heavy sweating, weakness, headache, dizziness, nausea, and muscle cramps. Do not assume a submissive who looks exhausted is simply experiencing an intense scene.

Move to a cooler environment, stop strenuous activity, and begin cooling down if symptoms appear. Hydration and regular breaks are especially important during hot weather. Confusion, collapse, or other signs of severe heat illness require urgent medical attention. Heat is not something you prove your endurance against.
