Hydration and exercise in heat
Exercising in the heat of the coast or lowlands requires adjusting routine and hydration. This guide offers general ideas; it does not replace assessment by a health professional.
Why it matters
In heat and humidity you sweat more and lose fluids and salts. Dehydration can cause fatigue, dizziness, headaches and cramps, and reduces performance.
Practical hydration
- Drink water before, during and after exercise.
- Increase intake on long or intense days.
- Watch urine colour: darker usually means low hydration.
- For prolonged effort, consider electrolyte drinks.
Timing and clothing
Train early or at sunset, in light breathable clothing, a cap and sunscreen.
Warning signs
Severe dizziness, confusion, nausea, strong cramps or lack of sweating call for stopping exercise, finding shade and hydrating; if they persist, seek medical care.
Adaptation
Your body adapts to heat in one or two weeks. Start with lower intensity.
