Four-month-old babies should avoid taking hot spring baths due to their lower sensitivity to water temperature. Long-term immersion in hot water may wash away the skin’s lipids, reducing its protective barrier. While parents can take their children to hot springs, it is important to control the duration and not stay too long. Hot springs have therapeutic effects, and it is recommended to visit regularly, but each session should not be too lengthy. When treating pediatric healthcare issues, it is advisable to adopt general treatment methods and seek professional help as soon as possible to avoid affecting the child’s growth and development.
