Final answer:
It is true that to avoid skin exposure to chemicals, you should wash your hands with soap and water. Following CDC guidelines and using the proper handwashing technique is essential for reducing the risk of chemical exposure and infections.
Step-by-step explanation:
To avoid skin exposure to chemicals, it is indeed true that you should wash your hands with soap and water. This process helps in removing harmful substances and reducing the risk of skin irritation or absorption of chemicals into the body, which can lead to various health issues. The CDC handwashing recommendations suggest thorough handwashing procedures, which include wetting hands with clean, running water, applying soap, and scrubbing for at least 20 seconds, especially the backs of the hands, between fingers, and under the nails.
Overuse of antimicrobial soap may lead to increased risk of infection, possibly because it may contribute to the resistance of bacteria to antibacterial agents, affect the skin's natural flora, or cause damage to skin, which serves as a physical barrier against pathogens. Another physical barrier against pathogens is the intact skin itself, which provides a chemical barrier through various secretions like sweat and sebum that can also have antimicrobial properties. However, the skin alone is not sufficient for preventing infections; hence, appropriate hand hygiene is crucial.
