Interestingly polar bears combine darks skin and hair that functions much like a fiber optic to absorb more heat from the sun. Some heat is still absorbed based on the nature of the object's material, but minimal additional heat is absorbed, making white the coolest possible color. And thirdly, when I refer to "black skin," I don't mean black as in black sky, you know EXACTLY what I mean. Not all the effects of pigmentation are advantageous. Black absorbs more heat because it also absorbs more light, and light energy changes into thermal energy, which gives off heat. However, because light clothes reflect more light when a person is outside, the accompanying heat from the sun is reflected as well. Vitamin D is involved in the absorption of calcium and is required for good bone strength as well as other things. Asian skin is more sensitive because the stratum corneum is thin.

Dark colors absorb a lot more heat than lighter ones because they absorb more light energy. Rather, black pigments absorb all visible wavelengths of light that happen to hit them. Try using thermometer strips sold at pet stores (to stick on the insides of reptile cages to monitor temperature). In cold climates dark skin entails more heat loss by radiation. If a certain substance reflects most light wavelengths, most heat energy will be reflected as well. In the beginning, in Africa, we lived in sunny areas with rapid natural changes. Black as a colour does absorb more heat. I’m a Scientist is like school science lessons meet the X Factor! My head gets VERY VERY HOT in the sun, which in turn makes me hotter. Nitrogen Zone.

Garlic and onion rubbed on the skin will work after a fashion, but are best applied internally, raw, and allowed to sweat out, in my opinion.

They do not absorb more heat, but rather more energy (Ultraviolet) which is then converted to heat through molecular motion in the dark pigment. black absorbs & RADIATES heat better, stay in the shade= Kirchoff's law. I’m not a physics specialist but I found this when I did some reading: “While dark skin is better protected from ultraviolet radiation, it does absorb more of the energy in visible light than light skin. The darker the object, the better it emits heat, because it’s a better absorber of light. Regardless, the heat absorption hierarchy of colors will always remain if all other factors are equal. Therefore, due to the nature of visual light, colors that reflect most wavelengths of light tend to be cooler than those that only reflect a few. Dark clothing can absorb more heat but if it is loose fitting it can set up a convection current with hot air leaving the top of the clothing and refreshing cooler air flowing in from the bottom.The air flow can further enhance the cooling effect by increasing the rate of evaporation of sweat from the skin.A nice example … Cold weather often leads to dry skin and irritation, both of which are more visible in darker skin tones.
