White is the best color for clothing in hot weather because it reflects sunlight rather than absorbing it, which helps keep the body cool by limiting heat absorption.
When the sun is beating down, the choice of clothing becomes important. White has a nice feature: it naturally reflects a large part of sunlight, unlike dark colors which tend to absorb that light and thus heat up more quickly. Very concretely, wearing white allows you to keep a good amount of solar radiation at bay, especially the infrared rays responsible for the intense heat felt on the skin. As a result, you feel cooler and less overwhelmed by the heat because the white garment retains much less thermal energy. It's like having a mini reflective shield on you, light and comfortable, which helps avoid the unpleasant sensation of burning in the sun.
Wearing white helps your body better control heat. White clothing absorbs much less sunlight compared to dark colors, which reduces the rise in temperature of your skin. As a result, your body expends less energy trying to lower this excessive temperature through sweating. Sweating less means a lower risk of dehydration, which in turn promotes better temperature regulation. Simply put, with white on you, your body stays more easily at a comfortable temperature despite the sun.
Wearing white when it's hot gives an immediate impression of freshness, simply because this color reflects heat instead of absorbing it. As a result, one enjoys a more airy and pleasant sensation directly on the skin, even aiding in the evaporation of sweat. The body breathes better, one feels less stifled by the ambient heat, and everyday comfort naturally increases. While dark colors quickly give the impression of being too hot, white provides a slight cooling effect that is very appreciated as soon as the sun shines brightly.
Wearing white when it's hot reduces the risk of heat strokes and hyperthermia, as it prevents the body from absorbing too much sunlight. By limiting excessive sweating, it also reduces the chances of becoming dehydrated. Since white decreases the feeling of overheating, it helps to avoid skin discomforts such as irritations or heat rashes. Overall, the less the body has to exert itself to regulate its temperature, the better your overall energy and comfort level in the sun. There is also less accumulated fatigue because the body spends less energy managing its coolness.
Several studies have proven that white effectively reflects sunlight, significantly reducing heat accumulation. An experiment published in the journal Applied Ergonomics demonstrated that individuals wearing white clothing exposed to the sun have a lower internal body temperature than those dressed in dark colors. Even the WHO recommends wearing light-colored fabrics, particularly white, to mitigate the risks associated with intense heat. Scientists also confirm that choosing light colors like white limits excessive sweating and thus indirectly improves body hydration. In short, science clearly supports the choice of white clothing in high heat.
A scientific study conducted in 1980 revealed that wearing white clothing can keep body temperature up to 5°C lower than wearing black clothing under the same climatic conditions.
Astronauts wear white space suits precisely because this color has a maximum reflection rate against the extreme solar radiation of space.
By choosing natural fibers such as cotton or linen for your white clothing, you further enhance their refreshing properties due to their superior ventilation and sweat evaporation capabilities.
In ancient cultures, such as that of Ancient Egypt, wearing white clothing during warm periods was already common, as it represented purity, cleanliness, and helped to shield against the scorching sun.
Indeed, wearing a white garment dampened in hot weather can significantly enhance the feeling of coolness. As it gradually evaporates, the water absorbs body heat, and the white garment optimizes this effect by reflecting external heat while the internal moisture promotes natural thermal regulation.
Absolutely, the fabric of clothing plays a crucial role in thermal regulation. Opt for lightweight, breathable, and absorbent materials such as cotton or linen, which promote sweat evaporation and thereby enhance the feeling of freshness, while wearing white to maximize the thermal benefits.
Wearing black absorbs a significant amount of solar energy, quickly increasing body temperature. This can lead to an increased risk of heat stroke, dehydration, or heat exhaustion, especially with prolonged exposure to the sun or during intense physical activities.
Although rare, a dark color can be beneficial in certain specific cases, such as when there is a cool breeze or strong air circulation. In these particular situations, the dark color absorbs more external heat, but air convection allows for better dissipation of this accumulated heat around the body. However, in general, white remains the preferred choice for most usual summer situations.
Yes, light colors such as beige, pale yellow, or pastel also reflect sunlight better than dark colors. However, white remains the most effective color, as it reflects almost all wavelengths of the light spectrum, further reducing heat transfer to the skin.
