Regular handwashing is one of the most effective measures to reduce the spread of viruses and bacteria. However, frequent washing, the use of sanitizers, and temperature changes between the cold outdoors and heated indoors can dry out the skin, weakening its protective function.
“If the skin loses too much moisture, it cannot fulfill its barrier function effectively. Although coronavirus is not transmitted through the skin, other pathogens and harmful substances can easily enter our bodies,” warns Dr. Mira Jakobs, Scientific Affairs Manager at Bayer.
Why does handwashing protect us so much?
Thorough handwashing can reduce the number of germs on the hands by up to a thousand times. This lowers the risk of pathogens entering the body through the mouth, nose, or eyes, and also prevents spreading them to others.
Soap plays a key role in this process: it acts as a detergent capable of breaking down the lipid membrane of bacteria and viruses, destroying their structure and inactivating them.
What about sanitizers?
In addition to washing, hand sanitizing remains necessary in many situations. It is important to choose products specifically made for the skin and not for surfaces, as the former usually include moisturizing agents that protect the skin barrier.
According to the Robert Koch Institute, you should check the label for indications such as “limited virucidal efficacy” or “virucidal,” which guarantee effectiveness against enveloped viruses, such as those that cause colds and flu.
The vital role of the skin
The skin is the largest organ of the human body, with a surface area between 1.5 and 2 m². Its outer layer, the epidermis, constantly renews itself and acts as a shield against external agents. When it becomes excessively dry, it loses its ability to protect us.
That’s why, in addition to washing and sanitizing our hands properly, it is essential to care for them: regularly moisturizing the skin with creams is just as important as hygiene itself.
