In the United States, many shoppers wear new clothes immediately, mistakenly believing they are clean. However, experts warn that these garments can contain harmful chemicals, bacteria, and even pests. Chemicals such as formaldehyde, used to prevent wrinkling, can irritate the skin, causing symptoms like itching and redness. Additionally, artificial dyes, particularly azo dyes, may lead to allergic reactions. Washing new clothes before wearing them is crucial to eliminate these risks. The Cleveland Clinic emphasizes that residues from dyes can cause skin irritation, especially for those with sensitive skin. Moreover, newly purchased items may carry bacteria like Staphylococcus and E. coli, which can pose health threats. Experts recommend washing clothes with soft, unscented detergent on a delicate cycle and separating them by color to maintain fabric quality. Despite these recommendations, research indicates that nearly 50% of Americans do not wash their new outerwear before use, highlighting a significant awareness gap regarding clothing hygiene.
