Mistake #1: Too-tight underwear
  Not only is too-tight underwear generally unflattering (hello, visible
 bulges and puckering), but it can also promote chafing of the skin and 
vaginal irritation, especially if you’re post-menopausal. “For women who
 are menopausal, their vaginal walls tend to be thin,” says Raquel B. 
Dardik, M.D., clinical associate professor, Department of Obstetrics and
 Gynecology at NYU Langone Medical Center. From that perspective, any 
underwear that’s tight enough to rub your skin can result in irritation,
 she explains. “If your skin doesn’t get irritated, then great — tight 
underwear won’t hurt you. But if you do get irritated because of 
friction, then it’s not recommended.” 
Mistake #2: Shapewear
  If your tight undergarment happens to be shapewear, like the popular 
hip- and tummy-slimming kinds or waist-cinching corsets, you run the 
risk of health complications beyond your appearance. “If it’s really 
tight, you could have nerve impingement and decreased circulation,” says
 Donnica Moore, M.D., a women’s health expert, who speculates that tight
 girdles and shapers can even produce numbness or tingling in your 
extremities. Furthermore, shapewear is notoriously difficult to take 
off. “Shapewear makes it very difficult to go to the bathroom, so when 
women wear them, they tend to hold it more than they should,” she says.
 
Mistake #3: Synthetic Fabrics And Silk
   When it comes to material, experts agree that your personal 
preference can dictate the fabric—as long as you make sure the crotch is
 lined with cotton. “Most of the underwear that’s available is fairly breathable,” says 
Dr. Dardik. “As long as they have a cotton liner where the vaginal area 
is, you’ll be fine.” But if you’re looking for optimal underwear 
conditions, steer clear of synthetic materials, and only wear silk on 
special occasions. “Silk and synthetic fabrics are not breathable, which
 increases the risk of moisture being trapped and retained, which can 
create a yeast or bacterial infection,” says Dr. Moore.
    
  
Mistake #4: Thongs
Even if thong underwear is more your granddaughter’s speed than yours, keep this tip in mind: If you have a propensity to get yeast or bacterial infections, thongs will only make things worse. “Thongs can be a unique transport vehicle for bacteria from the back to the front,” says Dr. Moore, referring to the spread of E. coli from the anus to the vaginal area. “There’s a lot of movement with the thongs, sliding back and forth—it doesn’t stay in place,” she says.
    Dr. Dardik agrees: “Thong underwear can be more irritating, because 
it has more contact with vaginal and vulval area, but that doesn’t mean 
women can’t wear them — you just have to find right type for you,” she 
says. Meaning, if you like wearing thongs and they don’t cause you 
discomfort, then go for it. “Just because women become grandmothers, it 
doesn’t mean they need to wear big ‘granny’ underwear,” she adds.
   
Mistake #5: Underwear at night
Most experts are proponents of sleeping in completely the nude — as long as you’re comfortable in your birthday suit. “Though it’s a matter of personal preference, from the perspective of breathing and airing things out, you should sleep without underwear,” says Dr. Moore. For women who are going through menopause, going underwear-less may make even more sense. “The more you wear, the more you have to take off when you get night sweats,” she says. No one wants to linger in cold, wet panties once a hot flash passes.Mistake #6: “Going commando” during the day
If breathable underwear is good, is wearing no underwear better? In a word: no. “No underwear causes a whole host of other problems, particularly because clothing doesn’t tend to have a liner,” says Dr. Dardik. “For one, if you’re wearing pants, the seam sits right in the vulval area and will constantly be rubbing the area,” which can irritate sensitive tissue. Secondly, the natural moisture produced by the vagina has nowhere to go when you’re not wearing underwear. “If you are wearing dresses or skirts, there’s nothing there to absorb vaginal moisture,” she adds. “Then you can become hot and sweaty down there, which, in itself, can irritate the skin. In theory [no underwear] makes sense, until you think of the details.”Mistake #7: Sweaty undies
       Women and men who tend to sweat should change their underwear 
regularly — twice a day, as opposed to once a day for people who 
typically stay dry. And anyone who works out should put on a clean pair 
of undies as soon as they’re able. “A warm, moist environment is the 
perfect place for yeast to grow,” says Dr. Moore, who recommends that 
sweat-prone people invest in underwear made of moisture-wicking material
 and avoid cotton underwear, which tends to stay wet once it gets wet. 
“All of these problems are compounded if you have incontinence to any 
degree — even a drop or two,” says Dr. Moore. “When you work out, you 
can try wearing a panty liner. That way, if you’re not in a position to 
change underwear, at least you can change the panty liner or take it 
off.”
      
Mistake #8: Non-hypoallergenic detergent
       Have unexplained itching in an uncomfortable place? Even if you 
don’t consider yourself to have sensitive skin, your vaginal area may 
disagree. “Another common irritation is a form of contact dermatitis,” 
says Dr. Moore. “The No. 1 cause of that is your laundry detergent. The 
tissues that your panties come in to contact with are a lot more 
sensitive than your elbows.” She also identifies dryer sheets as 
irritation culprits. “Many brands have a very high concentration of 
perfumes in them,” she continues. “I don’t know why we need our vaginas 
to smell like a garden, but I recommend that women use hypoallergenic 
cleaning products as much as possible.” Dr. Dardik concurs, the milder 
the better.
      
The good news
While you can make mistakes with the undergarments you choose to wear, infection typically isn’t a big concern for women over 50. “The good news about menopause is that your pH changes, making you less likely to get yeast infections and bacterial infections,” says Dr. Dardik.
         Smart underwear habits mostly boil down to personal preference,
 how easily your skin gets irritated, and your propensity for infection.
 “With all of these questions, it’s not like we have a wealth of double 
blind placebo trials to rely on,” says Dr. Moore. “It’s mostly 
conventional wisdom with a little medical thoughtfulness. Vaginal health
 depends on a lot of factors.”
