Fans and Heat Waves: Why They Can Make You Hotter and How to Stay Cool

The Illusion of Fan Cooling

• 💡 Fans create a feeling of coolness by tricking our brains, but they do little to prevent heat exhaustion.
• ⚠️ In extreme heat, fans can actually increase body temperature and dehydration.

The Science Behind Heat Strain

• 🌡️ Fans increase air velocity, which can lead to a gain in dry heat and increased dehydration.
• 🧠 As we age, our ability to sweat diminishes, making us more vulnerable to heat-related issues.

Effective Cooling Strategies

• 💧 Wetting your skin before using a fan is crucial for effective heat strain reduction.
• 💦 Using a spray bottle, sponge, or drenching clothes helps your skin lose heat through evaporation without excessive dehydration.
• ✅ The combination of fans and skin wetting can help manage heat strain even in temperatures as high as 116°F.
