Health experts warn of temperature impacts on skin and neurological symptoms

Health experts highlight how temperature and hygiene habits impact skin health and neurological symptoms. Dermatologists warn that during winter, oily skin still requires hydration, as cold temperatures, low humidity, and hot showers can damage the skin's natural protective barrier. The Sociedade Brasileira de Dermatologia emphasizes the importance of maintaining a cleaning and sun protection routine year-round.

For individuals over 60, hot and prolonged showers are particularly risky, as they can strip the epidermis of essential lipids, leading to dryness and irritation. Experts recommend lukewarm water and limiting bath time to 5–10 minutes.

Additionally, neurological health can be affected by heat through the Uhthoff phenomenon. In patients with multiple sclerosis, increased body temperature—caused by hot weather, exercise, or hot baths—can lead to a temporary worsening of symptoms like fatigue, visual changes, or weakness due to interference with nerve impulse conduction. These symptoms are typically transient and subside once body temperature returns to normal.
