If you don't wash your clothes properly or often enough, the oils can start to accumulate. The more the oils accumulate, the more likely it is that your clothes will begin to develop odors, and stains may start to appear under the arms or around the collar where most oils tend to collect.
"If you're wearing something for a few hours, and not sweating, it's probably okay to wait 2 to 4 wears before washing. Or, after a full day's use," says Dr. Gonzalez. "If you're working from home, it's probably okay to wait after 3 to 4 wears before washing your clothes."
There's no hard and fast rule for how many times you can wear clothing again, but experts say there are a few types that should be washed after every use: underwear, socks, tights, leggings and activewear. This advice also applies to any other clothes with stains, sweat, odor or visible dirt, Mohammed said.
Germs on clothes and towels can come from our own body. We all have bacteria on the surface of our skin, in our noses and in our gut. These are often harmless, but some can cause infection, particularly in people with skin problems or wounds.
If you skip the wash and develop contact dermatitis, Rebecca Baxt, MD, MBA, FAAD, a New Jersey-based dermatologist, says your skin will get red, itchy, and sometimes flaky. If very severe, she says it can even be blistered. Dr. Chi explains that the rash will occur where the clothing touches the skin.
Gerba: Yes. Clothing from ill individuals can become highly contaminated with germs, and it is best to have a strategy for proper handling and washing.
Another dermatologist, however, Will Kirby, M.D. of Hermosa Beach, CA told SELF that the chance of transferring viruses, bacteria, or other infections via unwashed garments is “not impossible — but the risk is very, very slim.”
The chemicals in clothing have been linked to health issues that can include neurotoxicity, liver, kidney, and lung disorders, and cancer – however, these symptoms are associated with long-term exposure. Whereas short-term exposure can lead to allergic reactions, skin irritation, and respiratory irritation.

Look for Oeko-Tex® or BLUESIGN® Certifications
Oeko-Tex and BLUESIGN are two international authorities that specifically address chemical safety. For example, Oeko-Tex 100 Standard certified textile means that every element of the textile is tested and contains no harmful substances to human health.
Most people should wash their sheets once per week. If you don't sleep on your mattress every day, you may be able to stretch this to once every two weeks or so. Some people should wash their sheets even more often than once a week.
For pajamas, they suggest washing them after three or four wears. That's about two pairs of pajamas a week. While this standard is a recommendation, it's not the general norm.
From the point of view of hygiene, it's ok to wear the same pair of trousers/pants for a week, and ok to wear the same jumper, providing they're not dirty or stained. Shirt, Tee shirt, socks, underwear should all be changed every day, (and washed in between wearing).
It is perfectly fine to wash clothes with just water, but the results won't be as quick or as effective as washing with laundry detergents. Laundry detergents have been developed to be very good at working with the water to lift away stains and leave your clothes spotless.
Baking soda is one of the first go tos for many people looking to get rid of that chemical smell on their new clothes. Fill a bucket or sink with water. Add 2 cups of baking soda and soak the clothing overnight. Wash the clothing as normal, adding ½ cup of baking soda to the rinse cycle.
After laundering, clothing can be tested with the D-Lead® test kit for lead dust (for procedure, see: www.esca-tech.com). If the test is positive, it maybe necessary to re-wash; add additional detergent to wash cycle, or switch to a detergent formulated to remove lead and metal dust.
PFAS have been found in a wide variety of garments such as rain jackets, hiking pants, shirts and yoga pants and sports bras made by popular brands like Lululemon and Athleta. Forever chemicals are used as surface treatments to block water and stains.
New Clothes Are More Used Than You Think
Probably not. But their hands and germs were on the clothing, and the clothing will go on you—so it only makes sense to wash the clothing prior to wearing it.
Some skin diseases such as dermatitis, scabies and fungal diseases can be transmitted by wearing unwashed second-hand clothes (1, 2).
Avoid unwashed fresh produce. Eating fresh produce provides important health benefits, but sometimes raw fruits and vegetables may cause food poisoning from harmful germs such as Salmonella, E. coli, and Listeria.
Viruses and fungi may die within days. But E. coli and salmonella, which can cause diarrhea, may survive a few weeks. Staphylococcus aureus, which causes staph infections on skin, may survive a month.
Germs such as E. coli, salmonella, and Klebsiella oxytoca can cause pneumonia, skin infections, abdominal cramps, vomiting, and diarrhea, especially in people with compromised immune systems. In fact, this nasty germ can live in the place that you clean your dirty clothes. That's right.
A good rule of thumb is to wash your jeans after every 3-10 wears, or when they start to smell. If you're regularly active in your jeans (think: manual work, anything where you work up a sweat), wash them every 3 wears, but if you're working at a desk, you can probably go through multiple wears without washing.
Dress pants or slacks: after 2-3 wearings. Jeans: after 4-5 wearings. Sweaters: up to 6 wearings, if worn with an undershirt; 1-2 wearings if worn without an undershirt. Suits/blazers/casual jackets: after 5-6 wearings.
The researchers found that a “sufficient” wardrobe consists of 74 garments and 20 outfits in total. As an example, they've suggested six outfits for work, three outfits for homewear, three outfits for sports, two outfits for festive occasions, plus four outdoor jackets and trousers or skirts.
