Is rain water safe?
Rain water’s generally soft, which is great. But if you’re thinking of stepping out for a little dance of joy in the rain, think again. If you live in a big city or a polluted area, rain water’s usually full of diluted pollutants from car fumes and the like, which you certainly don’t want to let anywhere near your skin. All these pollutants will damage and weaken skin cells.
If you want to wash with rain water, it would require boiling and cooling off. This process helps get rid of pollutants and other environmental nasties, but is it worth the hassle? Probably not.
So can I ditch the umbrella or not?
Even if (treated) rain water can be great for your skin, untreated rain can cause problems, so be sure to take precautions before — and after — heading outside in downpours.
Waterproof sunscreen provides a barrier against harmful chemicals in the rain. You’ll also want to cleanse well after you’ve been in a downpour.
