Those exposed to cleaning products—farmers, hairdressers, and printing workers— were found to have increased risk of getting asthma. Besides cleaning products, flour, enzymes, metals, and textile exposure at the workplace are also linked to higher rates of asthma. Occupational asthma holds a message for us all. Use green products and ventilate when you clean, especially if you have young children who spend lots of time on the floor and put most things in their mouths.
