Dermatologist Advises One Shower a Day to Protect Skin During Israeli Heatwave

As Israel faces a heatwave, dermatologists warn that common responses like frequent showers and prolonged exposure to pools or the sea can worsen skin dryness and irritation. Dr. Efrat Bar Ilan, a pediatric dermatologist at Clalit Health Services in the Dan-Petah Tikva district, explains that the skin’s protective barrier is already compromised during heatwaves, making it more vulnerable to external irritants. Excessive washing strips natural oils, leading to dryness, cracking, and heightened sensitivity.

Research published in Asia Pacific Allergy supports limiting showers to one short, lukewarm session daily to reduce skin irritation, especially in children. Frequent bathing increases dryness and exacerbates skin conditions. Sweat, containing salts, can further irritate the skin and cause itching, which may lead to cracks that allow bacteria to enter, intensifying inflammation. This explains why patients with atopic dermatitis often experience flare-ups during hot months rather than winter.

Air conditioning, while reducing sweat and heat discomfort, also dries out the skin, necessitating regular moisturizing and adequate hydration. Dr. Bar Ilan recommends using fragrance-free creams with ceramides or hyaluronic acid and mineral-based sunscreens containing zinc oxide or titanium dioxide for sensitive or atopic skin. She stresses that sun protection is essential in Israel due to cumulative sun damage risks.

For managing skin health in the heatwave, Dr. Bar Ilan advises limiting showers, moisturizing immediately after drying off, rinsing off saltwater after swimming, wearing breathable cotton clothing, and drinking water consistently. She also cautions to seek medical advice if red, itchy rashes persist beyond a few days or worsen, as secondary infections may require treatment. Understanding and adjusting skin care habits can prevent heatwave-related skin problems without fear of the summer heat.
