The best fabric for extreme heat? It’s more complicated than you think
Summary
Choosing the best clothes for extreme heat is more complex than just wearing light, loose fabrics. Scientists say the fabric type, weight, weave, fit, color, and activity level all influence how well clothing helps keep the body cool by allowing sweat to evaporate.Key Facts
- The body cools down mainly through sweat evaporating from the skin, so clothes should allow this process.
- Lightweight, breathable fabrics that let air flow easily are best for cooling in hot weather.
- How fabric fibers are woven or knitted affects breathability more than just fiber type.
- Natural fibers like cotton and linen tend to be more breathable than synthetic ones.
- "Wicking" fabrics move sweat away from the skin to help it dry faster but may not cool the skin as directly.
- The fit of clothes matters; loose clothes help ventilation, but tighter fits may be better for active people.
- Clothing designed to manage heat is an active area of scientific research due to rising global temperatures.
- Other factors like clothing color and treatments on fabric can also impact heat comfort.
