AI Overview
AI Overview
To acclimate to hot weather, gradually increase your heat exposure over 1-2 weeks by doing light activity in the heat (like walking or jogging for 30-90 mins daily), staying hydrated with water and electrolytes, taking breaks in the shade, and wearing light clothing; this process trains your body to sweat earlier and more efficiently, lowering your core temperature and heart rate. Listen to your body and slowly build up activity, as full adaptation takes time but significantly reduces heat stress.
Gradual Exposure
Start Slow: Begin with shorter periods (e.g., 20% of the day) and gradually increase daily exposure by about 20% over 7-14 days.
Combine with Activity: Physical exercise (jogging, marching) in the heat is more effective than just resting.
Aim for Two Hours: Build up to about two hours of daily heat exposure with activity for optimal acclimatization.
Hydration & Nutrition
Drink Plenty of Water: Don’t wait until you’re thirsty; stay ahead of dehydration.
Replenish Electrolytes: Consume sodium and electrolytes (through food or sports drinks) as you sweat more.
Eat Light: Opt for smaller meals with fresh fruits and vegetables.
During Heat Exposure
Listen to Your Body: Reduce intensity or duration as needed; you won’t perform as well as usual initially.
Take Breaks: Rest in the shade frequently.
Dress Appropriately: Wear lightweight, breathable clothing and a ventilated hat.
Consider Saunas: If you can’t exercise outside, a sauna can help, but active exercise is best.
What Happens to Your Body
Your body learns to sweat sooner and more effectively.
Blood plasma volume increases, making your heart work less hard.
More blood is directed to the skin for cooling.
You retain more salt, reducing electrolyte loss.
Important Considerations
Time Off: Heat tolerance decreases after about a week away from heat; prolonged breaks (over a month) return you to baseline.
Health Factors: Alcohol, illness, and obesity can hinder tolerance; fitness improves it.
