Living in the tropical region can be a torture sometimes, since the sun shines so mercilessly on us all year round. Most of us know that wearing black will make you feel hotter under the sun, while wearing white will make you feel cooler. But what about the other colours?
According to an experiment carried out in June 2019 by Japan’s National Institute for Environmental Studies, apart from wearing lighter colours, it seems that wearing warm colours will, ironically, make you feel cooler too.
In the experiment, nine different coloured polo shirts were placed on mannequin torsos under the Japanese summer sun. After five minutes of exposure, the fabrics’ surface temperatures were measured.
The results revealed that the white shirt was the coolest, followed by the yellow shirt. Both shirts had temperatures of around 30 degrees Celsius. The next coolest were the light grey and red shirts. In the middle were the purple, blue and green shirts, while the dark green and black shirts were the hottest, with surface temperatures of over 50 degrees Celsius.
This essentially meant that the white shirt and the black shirt had around 20 degrees Celsius difference in surface temperature!
