It might seem like a fundamental hygiene rule, but many individuals are quietly neglecting the habit of changing their underwear daily. Experts now caution that wearing dirty underwear is not only unpleasant – it can also pose genuine health risks, making it essential to change daily.
As alarming as it may be, a study conducted in 2021 discovered that an average pair of underwear harbors about 0.1 grams of fecal matter. With this in mind, going more than a day without switching to a clean pair is not just uncomfortable – it could lead to serious health issues, according to health professionals.
Dirty underwear
Despite clear hygiene recommendations, a significant number of young adults are not adhering to the practice of changing their underwear daily. A 2023 Newsweek survey indicated that 36% of Gen Z participants – those aged 18 to 24 – confessed to wearing the same underwear for over 24 hours, with an additional 14% stating they do this regularly. This means that nearly half of Gen Z has reported wearing the same undergarments for at least one full day or longer.
However, this behavior is not confined to the youngest demographic. The survey also revealed that 24% of millennials – individuals aged 25 to 34 – frequently wear the same pair of underwear multiple times.
In contrast, older adults demonstrated significantly better hygiene practices. Among those aged 55 to 64, 67% reported that they never wear underwear for more than one day, and only 3% admitted to reusing pairs.
Skin irritation or infection
Medical professionals warn that this increasing trend of extending wear-time is more than just a cosmetic issue. Bacteria, yeast, and moisture can accumulate in snug clothing, creating a perfect breeding ground for skin irritation and possible infections – particularly in areas with limited airflow.
“Both men and women can experience skin irritation, rashes, or aggravation of existing conditions like eczema or psoriasis if they wear the same underwear too many times without washing it; this is attributed to friction and moisture retention,” stated Sarah Roberts, a licensed skincare expert, in an interview with the Daily Mail.
‘Retain moisture and bacteria’
Roberts cautioned that prolonged use of underwear can result in infections such as yeast overgrowth and bacterial vaginosis.
Yeast infections can lead to symptoms like itching, burning, and a thick white discharge when the candida fungus proliferates. Bacterial vaginosis, which is often confused with yeast infections, typically presents with a fishy smell and gray or yellow discharge due to a bacterial imbalance.
“The vulva has folds and crevices that can trap moisture and bacteria more easily than male genitalia,” Dr. Archit Aggarwal, a dermatologist at ClinicSpots, explained to the publication.
Jock itch
Hygiene-related health risks are not exclusive to women; men are equally at risk, particularly concerning jock itch, a fungal skin infection characterized by an itchy, red rash in the groin, buttocks, and upper thighs.
While some believe that looser clothing like boxers provides better protection, experts caution that neglecting daily changes still carries significant risks.
“Men’s boxers, despite making less contact with the skin than women’s underwear, are not immune to these dangers – especially when worn repeatedly without being changed,” Roberts added.
Change your underwear at least once a day
While some might wear a pair of briefs for a second day in an emergency, medical professionals strongly advise changing your underwear at least once every 24 hours to minimize the chances of skin irritation and infections. This recommendation is even more crucial in situations where you sweat a lot.
“For individuals involved in vigorous physical activities or those who sweat profusely, it’s best to change your underwear more often,” stated Dr. Hannah Kopelman, a dermatologist at Kopelman Aesthetic in New Jersey. “In hot and humid conditions, changing your underwear more than once a day may be essential for maintaining proper hygiene.”
Dr. Aggarwal supported this advice and highlighted the need to be aware of early warning signs. “If you notice any discomfort, itching, or unusual discharge, change your underwear right away and consult a healthcare professional if needed,” he advised the Daily Mail.
