Summer time travels usually imply seashore time, with every little thing that this entails: from salt and sand to chlorinated pool water, sunscreen, sweat and every little thing in between.
Soiled towels is usually a quiet reason for bother for these with delicate pores and skin, exacerbating circumstances like pimples and eczema. So, how dangerous can it get once we depart our seashore towels and pool towels unwashed for days?
Humidity, sweat, sunscreen and sand are the proper breeding floor for micro organism, and moisture performs an enormous function in microbial progress. Micro organism want water to develop, in response to Dr. Joseph Battistelli, an affiliate professor of biology at Virginia Commonwealth College.
So, how usually ought to we wash our seashore towels on trip, and what components contribute to this calculation? HuffPost spoke to 4 specialists on micro organism to get some solutions.
How a lot micro organism can actually stay on a towel?
“A towel that’s been used multiple times, especially when it’s stayed damp, becomes a breeding ground for bacteria,” mentioned Dr. Hannah Kopelman, a board-certified dermatologist at Kopelman Hair Restoration.
“The most common bacteria found on beach towels are: Staphylococci, Micrococci and Diphtheroids (Coryneforms), in addition, environmental bacteria from sand and water would also be found on beach towels left unwashed,” defined Megan Meyer, a science communications guide with a Ph.D. in microbiology from the College of North Carolina at Chapel Hill.
Mayer mentioned seashore sand additionally contains these widespread forms of micro organism: Escherichia coli (E. coli) and enterococci, Salmonella spp., Campylobacter spp., Staphylococcus aureus, and methicillin-resistant Staphylococcus aureus (MRSA).
“Under ideal [for bacterial growth] conditions, E. coli populations can double every 20 minutes. Microbial growth on a beach towel would be much slower than this because it is not an ‘ideal’ environment,” Battistelli mentioned.
“A lot of pathogens are what we call ‘opportunistic pathogens,’ he continued. “They are native members of our skin microbiome and don’t normally do us any harm. However, if we are injured, immunocompromised, or transfer the bacteria to a new person, especially an at-risk person, then the bacteria can take advantage of the opportunity to cause infection. Towels can harbor yeasts and fungi, too,” he added.

Can soiled towels trigger infections?
“I’ve seen everything from folliculitis to ringworm in patients who’ve reused moist, unwashed towels, especially after sweating or swimming. Fungi and bacteria thrive in damp, warm environments, and a rolled-up beach towel can be just that. If you have any cuts, shaving nicks, or even inflamed hair follicles, bacteria can sneak in and cause an infection. It can become a medical issue,” defined Kopelman.
“The difference between using a towel after the beach versus after a shower at home will mainly result in differences in microbial profiles. It’s important to note that beach sand often contains fecal bacteria from wildlife, runoff contaminants or toxins, and microplastics,” mentioned Meyer.
When utilizing a towel at residence, the micro organism current are completely different. “I would expect the towel [at home] to mostly have skin-associated bacteria since the towel was used to dry off a person,” mentioned Battistelli.
The kind of water publicity additionally issues. “Ocean water contains salt, which tends to inhibit bacterial growth. Towels used briefly after a swim in clean saltwater may remain relatively clean. However, freshwater environments, like lakes or rivers, are more likely to harbor bacteria, fungi, or other microbes, particularly in warm, stagnant conditions,” mentioned Prodanovich.
For swimming pools, it’s not at all times as clear-cut for the reason that temperature and the focus of chlorine or different disinfectants play an vital half in bacterial progress.
When you’ve got circumstances like eczema or athlete’s foot, this could improve the chance of infections, particularly with recurring reuse of unwashed towels, Prodanovich mentioned.
Your towel may impression pimples and different pores and skin circumstances.
The pores and skin on the physique will be severely impacted by an unwashed towel. “I’ve seen patients develop acne-like breakouts or flare-ups of eczema simply from using dirty towels. Towels trap sweat, oils, dead skin, and bacteria; all of which can irritate sensitive skin and clog pores,” defined Kopelman.
For acne-prone individuals, towels which are used on the physique can reintroduce acne-triggering micro organism. Kopelman encourages her sufferers to vary towels and pillow instances very often for related causes.
“If you have sensitive skin or eczema, the risk or irritation is heightened, as the skin barrier may already be compromised. In those cases, even mild microbial buildup can lead to inflammation or flare-ups,” mentioned Prodanovich.
Are you able to share towels with others?
Keep away from sharing towels with others, as this could unfold fungal infections like ringworm or athlete’s foot, particularly in case you have any abrasions or open wounds that are available in contact with the towel; this is usually a recipe for catastrophe.
“I wouldn’t recommend it, especially if you are immunocompromised or have other ailments that put you at risk for infection,” agreed Battistelli.
Does the fabric of the towel make a distinction?
It actually does, defined Meyer: “Research has shown that bacteria can survive nearly 2.5 times longer on synthetic fabrics like polyester or microfiber, compared to cotton towels. It’s also been shown that bacteria stick more to fabrics like polyester and, therefore, are more active in polyester towels.”
Right here’s the best way to understand it’s time to clean your towel.
There are some warning indicators, just like the odor (musty or bitter odor) and texture (stiffness or slimy texture), that your seashore towel is overdue for a wash. “If your towel smells even slightly musty, has any stiffness to the fabric, or feels damp hours after use, it’s time to wash it. That musty smell is often mildew or bacterial overgrowth,” mentioned Kopelman.
“And if it’s been sitting in a beach bag for hours, even if it seems dry, it may still be loaded with microbes,” she added.
So, how usually do we actually want to clean our seashore towels?
“Realistically, I recommend washing beach towels every two to three uses at most, but ideally daily, especially if you’re lying on it, sweating, or it stays damp for long periods,” famous Kopelman.
“I would wash the towel every day or get a fresh towel between beach sessions,” mentioned Battistelli.
“If possible, use a fresh towel daily, or at a minimum every other day, and allow it to air in direct sunlight and dry fully. Choose 100% cotton towels for their superior breathability and natural antimicrobial qualities,” mentioned Meyer.
Per the specialists, the perfect situation is washing your towel each few days, and even each day. This may not be potential on trip, so there are just a few alternate options specialists suggest.
First, shake out sand and any particles after use. Then depart the towel to dry within the solar when potential, as UV publicity can assist lower bacterial progress. “UV rays have natural antimicrobial effects, so laying your towel out in direct sun is better than leaving it bunched up,” famous Kopelman.
“Hang the towel fully stretched out in a well-ventilated area or direct sunlight,” agreed Prodanovich. Earlier than you employ it once more, make sure the towel is totally dry.
Observe that if you’re in a damp setting, even air-dried towels should still retain moisture that helps bacterial progress. Keep away from leaving moist towels bunched up or in a bag.
“If daily washing is not practical, allowing the towel to dry thoroughly between uses and washing it every two to three uses is a reasonable compromise,” mentioned Prodanovich.
Have one towel to lie on and one to dry your self with, to reduce the buildup, and rotate between a number of towels, if potential, to permit extra drying time.
It’s additionally vital to clean your seashore bag or tote infrequently, since “it holds damp towels and swimsuits and can become just as funky,” mentioned Kopelman.
Lastly, a behavior that’s usually neglected is drying the towel utterly earlier than reuse, which is much more vital than how often you wash them, defined Prodanovich.
Needless to say these are short-term fixes when correct washing shouldn’t be an possibility. When you may wash your towels, you may add white vinegar to the rinse cycle to remove micro organism and odors.
