Choosing Summer Clothing: Color, Fabric, and Fit Affect Comfort in Heat

During hot summer days, it is commonly recommended to wear white, lightweight, and loose clothing, but scientific findings show that the best choice is more complex. Light-colored clothes reflect more sunlight, while dark clothes absorb heat. However, loose black clothing can still be comfortable because the air circulation between the fabric and skin helps dissipate heat better than tight white clothes. The fit of the garment is crucial: loose, thin clothes allow air to flow around the body and help sweat evaporate, whereas tight fabrics can stick to the skin, especially in humid conditions, hindering the body's natural cooling.

Fabric type also matters. Cotton and linen are comfortable for everyday wear, but cotton that absorbs a lot of sweat can become heavy and wet. For physical activity, synthetic fabrics designed to wick moisture dry faster and may be more effective. In direct sunlight, wearing long, light-colored, and lightweight clothes is advisable to protect against UV radiation. The Centers for Disease Control and Prevention (CDC) recommend wearing loose, lightweight, and light-colored clothing during extreme heat, along with drinking plenty of fluids, using sunscreen, and reducing activity during peak heat hours.

The conclusion is that no single fabric or color suits all situations. For regular days, thin, airy, and loose clothing is best, while for sports, moisture-wicking and quick-drying garments are preferable. The Israeli Meteorological Service recently issued a warning about temperatures exceeding 44 degrees Celsius, emphasizing the importance of appropriate clothing choices in extreme heat.
