If we have long clothes and long sleeves in summer, we must be laughed at by our mother: Is your brain watt~
Why can Arabic robes fight against the heat of Takaar, but are not suitable for the hot summer in our country Southern ?
Qatar World Cup takes Arabic robe with a strong Middle Eastern characteristics as mascot
Let’s first look at the climatic conditions in Qatar.
Qatar climate
Qatar is a tropical desert climate and has several characteristics:
1. Dry and less rain 2. Strong ultraviolet rays 3. High wind and sand
, and the white robe can perfectly deal with these problems.
First, maintain humidity;
In summer, the human body mainly relies on evaporation to dissipate heat. The robe blocks the exchange of dry air between the body surface and the outside world, and can keep the body from evaporating too quickly at a high temperature of 40 degrees, resulting in dehydration. Dehydration will be a very serious consequence if the desert is dehydrated.
Although most of the earth in southern my country is hot in summer, the relative humidity is relatively high, and belongs to the humid and heat type. And the water source is abundant, and dehydration is unlikely.
Second, reflecting sunlight;
The ultraviolet rays in the desert area are extremely strong, and wrapping from head to toe is also better to resist ultraviolet rays.
White can reflect light . We have all had this experience. In summer, you can reflect sunlight by riding an electric bike with a white cushion. It won't get hot even if you sit on the cushion.

Most of us in the south are hot in summer, but there are more clouds and rain, and the ultraviolet rays are not that strong, so the necessity is not that great.
Third, forming air convection ;
robe design, the collar and sleeve openings of the robe are relatively large, and they are considered from the perspective of being loose in the wear and good internal and external ventilation.
Wearing such a loose robe can play a role in blowing during activities, and when walking and moving, air flow can be formed to promote ventilation in the robe. The flow of air takes away the body's heat.
Long gown forms air convection
I wonder if you have this experience. The places where the sun shines in the north are very hot in summer, but as long as there is shade, it will become cooler.
Because North is relatively dry and not as heavy as moisture. There is less water vapor in the air, and is lower than that in the south with more water vapor than . So the temperature difference will be large.
The air humidity in the south is high and the specific heat capacity is large. It is also hot when there are shades of trees. It's hot during the day and at night. Even if there is air flowing, it is hot air blowing. Therefore, the formation of air convection will not help much in the humid and hot summers in the south.
So Arabic robe is indeed only suitable for dry, rainy, windy and sandy desert areas, and is not suitable for humid and hot southern climates. Of course, if you travel to the desert in summer, you can also try wearing wide robe and large sleeves~
