When the summer heat intensifies, many people instinctively turn on a fan for quick relief. However, experts warn that a fan isn’t always the safest option — especially when the air temperature is higher than your body temperature.
When a Fan Works Against You
Your body works hard to regulate its temperature in hot weather. If you run a fan while the surrounding air is hotter than you are, you’re essentially blowing heated air directly onto your skin. Instead of cooling you down, this can raise your core temperature, putting more stress on your heart and vital organs.
One health expert compares it to stepping into an open sauna — the air moves, but the heat still surrounds you.
Heat-Related Illnesses You Could Face
Using a fan incorrectly in high temperatures can lead to:
- Heat exhaustion
- Heat stroke (potentially fatal)
- Muscle cramps
- Severe dehydration
Watch for warning signs such as:
- Headache
- Dizziness or loss of balance
- Nausea
- Heavy sweating without relief
- Elevated body temperature
- Weakness or fatigue
If these symptoms appear, heat stroke may be developing — a medical emergency that requires immediate attention.
Are Portable Fans Any Better?
Small handheld fans, popular in summer, often offer little relief in extreme heat. The exception is a misting fan, which sprays water onto your skin and uses evaporation to remove heat — a much more effective cooling method.
How to Know a Fan Is Doing More Harm Than Good
- The air feels hot rather than refreshing.
- You’re sweating more but not feeling cooler.
- You feel dizzy or nauseous while it’s on.
Safer Alternatives for Staying Cool
- Spend as much time as possible in air-conditioned spaces (home, malls, libraries).
- Drink plenty of water; avoid excess caffeine or alcohol.
- Wear loose, light-colored clothing.
- Eat smaller, lighter meals throughout the day.
- Stay in shaded areas when outdoors.
- Cool pulse points (neck, wrists, underarms) with cold water or damp towels.
- Position a fan to blow air out of a window to expel hot air, rather than directly on your body.
Best Cooling Drinks During a Heatwave
Avoiding a fan is only part of the solution — your body needs proper hydration to stay safe. Here are some of the best drinks for hot weather:
- Cold water — the simplest and most effective choice.
- Yogurt drinks — rich in probiotics and hydrating.
- Cold milk — high in calcium and protein, helps reduce body heat.
- Fresh fruit juices — such as watermelon, orange, or lemon-mint, for vitamins and freshness.
- Chilled herbal teas — like hibiscus or mint, known for cooling properties.
💡 Pro tip: Avoid sugary sodas and high-caffeine drinks like coffee or energy drinks — they can accelerate fluid loss.
