Dermatologist urges lukewarm, short showers to protect skin
Experts say brief cleansing with mild products helps preserve the skin’s barrier, with cautions against hot water and aggressive routines
A dermatologist at Iowa Health Care is advising that lukewarm, short showers are better for the skin than long, hot sessions, arguing that hotter water can strip away natural oils that the skin relies on as a barrier. The guidance emerged in coverage compiled by The Associated Press and has been reflected in a downstream Health section story published December 16, 2025. The advice comes as researchers and clinicians emphasize approaches that protect skin’s moisture and reduce irritation.
Negbenebor notes that many people default to hot water and extended shower times, which can leave skin dry and irritated. She recommends a brief shower using lukewarm water and cautions against overusing expensive body products, including strong cleansers, exfoliators, or shower oils. The goal, she said, is to treat the skin gently and avoid overdoing any single product that can disrupt the barrier. In the broader discussion, doctors highlight that showering helps remove dirt, sweat, and oils, but the routine should be restrained to minimize potential harm.
Experts outline a practical, five-point approach to lathering up without causing damage. First, time and temperature matter: a short, lukewarm shower is preferred over a long, hot session, as prolonged exposure and high heat can strip away essential oils needed to keep skin moisturized. Second, soap selection matters: choose a mild cleanser suited to sensitive skin and avoid highly perfumed or antibacterial formulas unless medically indicated, since these can increase dryness. The original guidance also emphasizes washing the hair first, using shampoo followed by conditioner, before moving on to the body, to minimize irritation on the skin after cleansing.
Third, don’t double-cleanse. While influencer trends push layering an oil-based cleanser with a water-based cleanser, dermatologists warn that this can be unnecessary for most people and may not improve cleansing outcomes. Fourth, consider applying an oil or oil-based moisturizer after stepping out of the shower to lock in moisture and support the skin barrier. Fifth, exfoliation should be limited. Aggressive scrubbing or frequent exfoliation can leave skin dry or irritated; if exfoliating, milder options containing lactic or glycolic acids are suggested for many users due to their gentler action. In cases of specific conditions such as hidradenitis suppurativa, clinicians may adjust product choices to minimize irritation.
The guidance is framed as a general, skin-friendly routine designed to protect the barrier, rather than a one-size-fits-all prescription. Health professionals stress that individual skin types and conditions can alter recommendations, and people should consult a clinician if they notice persistent dryness, itching, or irritation after bathing. While the public health framing emphasizes simplicity and restraint, critics note that consumer products vary widely in ingredients and that what works for one person may not suit another. The overall message, however, centers on reducing exposure to hot water, limiting product layering, and using products tailored to sensitive skin when possible.
