We randomly tend to throw our towel on the bed or anywhere on a surface which catches bacteria and transfers it to our skin. Also when you wipe yourself with a towel, bacteria and dead skin cells transfer to the fabric leading to skin infections if reused for too long.
Experts suggest that we should dry our towel properly under the sun after every use and wash it twice a week to keep germs and bacteria away.
Pro tip- Keep your towel separate to avoid germs from skin of other people living with you.
Also watch: How often should you really be washing your bras? It's probably more often than you think!
