As temperatures soar during extreme summer heatwaves, choosing the right clothing can significantly affect comfort and health. Experts recommend prioritizing loose fits, light colours, and natural fibres to help the body regulate temperature.
Why Fabric Choice Matters
Natural fibres such as cotton, linen, and bamboo allow air to circulate and wick moisture away from the skin, aiding evaporative cooling. Synthetic fabrics like polyester and nylon trap heat and moisture, increasing discomfort and risk of heat-related illness. According to Dr. Sarah Johnson, a thermal physiologist at the University of Portsmouth, 'Linen can be up to 3 degrees Celsius cooler than synthetic fabrics in direct sunlight.'
Colour and Fit: Key Factors
Light-coloured clothing reflects sunlight, while dark colours absorb heat. A study by the University of California found that white shirts reflect about 90% of visible light, whereas black shirts reflect less than 10%. Loose clothing also promotes airflow, reducing skin temperature by up to 2 degrees Celsius compared to tight garments.
Accessories and Sun Protection
Wide-brimmed hats, UV-blocking sunglasses, and lightweight scarves provide additional protection. Cooling towels or neck wraps soaked in water can lower body temperature for hours. Sunscreen is essential even under clothing, as standard fabrics offer only UPF 5-10; specialized sun-protective clothing with UPF 50+ blocks 98% of UV rays.
Footwear and Layering
Open-toed shoes or breathable sneakers help keep feet cool. Layering lightweight pieces, such as a cotton shirt under a linen shirt, can provide adjustable insulation. Avoid wearing multiple layers in direct heat, as this reduces sweat evaporation.
In extreme heat, staying hydrated and limiting outdoor activity during peak hours (10 a.m. to 4 p.m.) remains crucial. With the right clothing choices, individuals can reduce heat stress and enjoy summer safely.
