When the temperature exceeds 30 ° C, the air temperature is not much worse than our normal body temperature, and the heat on our body mainly relies on sweat evaporation to dissipate heat.

If the wind is too strong, the surface temperature of our skin will drop quickly, the pores will be closed, and the sweat on the body will not evaporate, so it will still feel hot.

People who stay in a strong wind environment for a long time may also suffer from fatigue, back pain, headache, dizziness, nausea and vomiting and other “holding sweat” and discomfort.

So from this point of view, the air volume is not the greater the better, want to comfortably cool, continue to blow soft wind is better.
