‘OVEN EFFECT’ IN EXTREME HEAT, WHO WARNS: BE CAREFUL WITH ELECTRIC FAN USE
The World Health Organization (WHO) does not recommend using electric fans as the primary means of cooling when the temperature exceeds 40˚C. In such extreme heat, electric fans no longer provide cooling; instead, they simply push hot air onto the skin, resulting in the so-called "oven effect".
Why are electric fans dangerous at 40˚C and above?
Heat Gain: When the air is warmer than normal body temperature, it heats people up faster rather than cooling them down.
Dehydration: Fans speed up the evaporation of sweat, which may provide short-term relief but quickly dehydrates the body, increasing the risk of heat stroke and heat exhaustion.
Smart Cooling Tips:
If you have air conditioning (AC), you can use the "AC + Fan Combo" for maximum savings:
Set the AC to 27˚C: This is higher than the standard setting but still comfortable.
Turn on the Electric Fan: This helps the cool air to spread quickly.
Result: According to WHO, the room will start 4˚C cooler. Since the AC compressor does not have to work as hard, it can save up to 70% on your electricity bill.
Important Reminder from DOH:
Don't forget to drink 8 to 10 glasses of water every day. If your area is very hot and does not have proper ventilation, it is better to move to public places with air conditioning such as malls or libraries to avoid the risk of extreme heat.
