A study conducted by Kaiser Permanente reveals that the types of thermal paper and ink that are used for most supermarket, ATM and POS receipts contain high levels of bisphenol-A (BPA), a chemical that increases your body’s production of the female hormone oestrogen.

The scientists warn that oestrogen boost — along with some other BPA-triggered hormonal changes — harms your erection.

According to the researchers, ATM receipts, airport baggage tags, POS printouts, lottery tickets, etc., are all printed on this BPA-heavy kind of paper.

As you’ve probably heard before, hard plastics and canned foods are also common BPA sources.

So, as much as possible, limit your contacts with items containing BPA.

Instead of tucking your ATM or POS printouts into your pocket, get a wallet for them, and always wash your hands before you eat each time you touch them.
