Popular belief recommends white for hot summer days, however, science says otherwise, the best option is black and loose clothing.
White clothes can make you feel fresh, but not for long. Mundo scientist Arturo Quirantes, a professor at the University of Granada, Spain, told the BBC that physics plays an important role.
White color repels the sun's rays, so external solar energy will not be absorbed by white clothes, but the factor that people don't consider is that the body also generates heat, and white clothes do not allow come out.

The color black on the contrary absorbs energy. On the one hand, it may feel a little hot when receiving the sun's rays on the garment, but due to the convection process, black clothing also absorbs body temperature, and the wind will simply release everything, from the body and from the garment to the time.
Convection is one of the three ways in which heat is transferred: conduction, convection, and radiation, by which heat is transported between areas with different temperatures. Convection occurs only through materials, the evaporation of water or fluids
According to the scientist, the best alternative is to wear loose black clothing, which absorbs outside temperature, body temperature and with the help of the wind, and in this way you will stay cool.
"We emit thermal energy. If we wear white clothes, the heat we emit bounces off the fabric and cannot escape," says the scientist. "On the other hand, if the fabric is black, it absorbs it. And if there is a breeze, it carries the heat by convection, which is an efficient mechanism to keep us cool." ends.
Keep in mind that this solution only works if there is wind and if the clothes are loose, if the clothes are tight or not breezy, the best alternative will be white.
