Underwear's Shelf Life: When to Toss Your Old Undergarments
Your underwear is like a team member that works hard to keep you comfy, but it also traps yucky stuff like sweat and germs.
That's why it's important to change them daily, and sometimes even twice a day, especially if you're sweating a lot.
Think of it like brushing your teeth; you wouldn't use the same toothbrush for a year, right?
Experts suggest replacing your underwear every 6 to 12 months because even washing can't get rid of all the bacteria.
You'll know it's time to toss them if they're stretched out, have holes, stains, or smell bad.
Choosing cotton underwear helps your skin stay healthy.
Keeping on top of this might be a small thing, but it keeps you feeling fresh and healthy!
Underwear should be replaced every 6 to 12 months.
Wearing old innerwear can lead to skin irritation and infections.
Even with washing, underwear can harbor bacteria and fungi.
Daily washing is recommended, and more frequently in hot or humid conditions.
Look for signs like loss of elasticity or persistent odor to know when to replace.
