"When Temperatures Top 40°C, Electric Fans Can Become Dangerous"... WHO's Unexpected Warning

It is truly hot these days.

The daytime high in Yangsan, Gyeongsangnam-do, reached 42°C (108°F). It broke record highs, and a nationwide heat wave continues.

However, it is said that when temperatures exceed 40°C (104°F), electric fans can actually induce more heat.

Let us look at the recommendations from the WHO together.

First, they emphasized that electric fans should be used when temperatures are below 40°C (104°F).

The breeze from a fan promotes the evaporation of sweat to cool the body, but when the air temperature exceeds skin temperature, you end up blowing hot air, which can actually raise your body temperature.

Sufficient fluid intake is also important.

The WHO recommended drinking 1 cup of water per hour and at least 2 to 3 liters of water a day.

They also introduced that wearing light, loose-fitting clothing, taking a cool shower, or using a wet towel to lower body temperature are effective methods.

The WHO estimates that heat waves have been associated with an average of 489,000 deaths worldwide every year from 2000 to 2019.

As climate change increases the frequency and intensity of heat waves, they emphasized that individuals practicing preventive measures is more important than anything else.
