External factors that cause dry, cracked hands
Environmental influencescan on the one hand cause the skin of the hands to dry out, especially when it is cold and windy. The humidity outside is lower in the cold season than in the summer. And indoors, the warm and dry heating air removes additional moisture from our skin. In addition, the skin's sebaceous glands produce less sebum at lower temperatures. Due to the lack of an oily film, the moisture on the surface of the skin evaporates faster.
But it's not just cold temperatures that affect our hands. In the summer, too much sun, swimming in chlorinated or sea water and dry air can also cause the skin of the hands to dry out.
Frequent intensive hand washing with drying washing water and soaps or alcohol-based disinfectants can also dry out the skin. People who work in a lot of contact with water or skin-damaging substances often suffer from rough and cracked skin on their hands. This applies, for example, to hairdressers, nursing and cleaning staff, but also employees in the construction industry and catering.
