Hand hygiene: Temperature is secondary to washing technique

Andrea Rückle from the Federal Institute for Public Health (BIÖG) states that water temperature is not a decisive factor for hygiene when washing hands. While warm water is more effective at dissolving fats, the use of soap makes the temperature of the water secondary to the actual washing technique.

Experts emphasize that thoroughness and time spent scrubbing with soap are the most critical elements for preventing the spread of pathogens such as colds, flu, and gastrointestinal infections. Additionally, using cold water is noted to be gentler on the skin, as it helps prevent dryness.
