Health experts have warned that thermal paper receipts commonly used in shopping malls may pose serious health risks due to the presence of bisphenol A (BPA) and bisphenol S (BPS). These chemicals can quickly be absorbed through the skin, sometimes within 10 seconds of contact, and the absorption rate increases significantly if hand lotion or sanitizer is used beforehand. Studies suggest that BPA and BPS can disrupt hormonal balance, potentially causing irregular menstrual cycles and increasing the risk of breast cancer in women. Pregnant women are particularly vulnerable, as exposure may affect fetal development, leading to low birth weight, weak immunity, or premature birth. Experts recommend opting for digital receipts instead of printed ones, washing hands immediately after handling receipts, and avoiding the use of sanitizers before touching them to reduce exposure to harmful chemicals.
