Western Europe is experiencing its most severe heatwave on record, forcing over 1,000 schools in the UK to close and causing a surge in hospital admissions.
The central and eastern United States also face intense heat ahead of the Fourth of July holiday, according to The Guardian.
Extreme temperatures raise difficult questions about daily wardrobe choices.
Los Angeles stylist Sophie Strauss notes that dressing for extreme heat remains a constant struggle for most people trying to stay comfortable while masking body sweat.
Warm-weather dressing requires garments that effectively move heat and moisture away from the body.
Experts generally recommend prioritizing natural fibers like cotton and linen, though final choices regarding fit and form remain personal.
Choosing the Right Fabrics
Sophie Strauss observes that most individuals prefer clothing that is a bit looser and more flowy. These silhouettes prevent materials from clinging to the skin during high temperatures.
Dr. Saetbyul Park, assistant professor of apparel and textile design at Michigan State University, states that linen is one of the coolest fabrics for summer due to its breathability and moisture absorption.
Its lightweight and stiff structure prevents it from clinging when wet.
Dr. Park also recommends cotton because it is absorbent, breathable, easy to care for, and durable.
However, heavy cotton fabrics like denim trap heat and become heavy with sweat, making lighter alternatives like chambray preferable.
While silk is a natural fiber, experts suggest avoiding it in extreme weather.
Sophie Strauss explains that silk fiber is insulating, meaning covering a lot of the body in silk might increase warmth.
The Risks of Synthetic Textiles
Synthetic fabrics such as polyester, nylon, or acrylic present distinct disadvantages during extreme heatwaves.
Materials like polyester and nylon have moisture-wicking properties but often remain highly uncomfortable when temperatures spike.
Synthetic options feature tight weaves that lower breathability and trap heat against the body.
Dr. Doris Day, a board-certified dermatologist and associate professor at NYU Langone Medical Center, notes this can impede natural temperature regulation and cause heat rash.
Polyester garments also tend to retain unpleasant odors.
A 2014 study confirmed that polyester attracts odor-causing bacteria, resulting in a smell that is significantly stronger, more sweaty, and more sour compared to breathable cotton.
Environmental data adds another reason to avoid these materials.
A 2020 report revealed that 4,000 metric tons of microfibers from synthetic clothing had been released directly into California's natural environment.
Sophie Strauss points out that synthetic materials are widespread in modern closets.
Many people do not realize how much of their everyday clothing is made from polyester or poly blends instead of pure natural textiles.
Managing Moisture and Smart Color Selection
Dermatologists emphasize the importance of changing out of wet garments quickly.
Dr. Doris Day warns that staying in sweaty clothes too long can cause heat rash, acne, or fungal acne breakouts within hair follicles.
Color choices play a significant role in masking visual sweat stains.
Sophie Strauss identifies heathered grey as the worst choice because its black undertones create a severe, highly visible contrast when wet.
Darker colors like navy or dark green hide moisture much better because their appearance changes very little when wet.
However, these dark shades absorb more heat than light colors, though they offer significantly more protection against harmful sun rays.
Sophie Strauss suggests using large patterns as an alternative method for hiding sweat stains.
She compares a busy pattern to a busy tablecloth because it effectively covers visual imperfections on the fabric.
Visible sweat patches remain an indicator of proper biological functionality during severe heatwaves.
Dr. Doris Day notes that sweating is a healthy process that should not be entirely eliminated through procedures like neuromodulator injections.
