"It's best to change your pajamas every day" Dr. Freestone stated, "If possible, it's best to change your pajamas every day," adding, "If you shower before bed and don't sweat much, you can wear them up to three or four times. " However, she pointed out that most people repeatedly wear the same pajamas, exposing themselves to body odor and infection risks.
She especially emphasized that those who sweat heavily should change their pajamas daily, as odors can intensify more easily. Because pajamas are in direct contact with the skin, they provide an environment where microorganisms can easily thrive. Millions of bacteria, fungi, and viruses reside on human skin.
The frequency of washing pajamas varies from person to person. Some people change them daily, while others wear the same set for several days or even over a week. On the 23rd (local time), Primrose Freestone, Associate Professor of Clinical Microbiology at the University of Leicester, emphasized the importance of pajama hygiene in an interview with the Daily Mail.
About half a cup of sweat is released during sleep, most of which is absorbed by pajamas, creating warm and moist conditions ideal for microbial growth. These microorganisms feed on dead skin cells, sweat, and sebum, producing substances that cause body odor. Additionally, eating while wearing pajamas can leave food particles behind, further promoting bacterial activity.

Throughout the day, passing gas can leave several milligrams of fecal matter on underwear.
If these contaminants accumulate on pajamas, they can become a source of unpleasant odors. Pajamas can serve as a route for infection transmission between people According to research by the London School of Hygiene & Tropical Medicine (LSHTM), bedding and pajamas can act as pathways for infections to spread among individuals. Pajamas that come into direct contact with genital areas and bodily fluids are particularly susceptible to transmitting infections compared to other clothing.
Attention should also be paid to infectious diseases such as Norovirus, which can be transmitted via fecal matter. In addition, skin cells left on pajamas can become food for house dust mites or fungi, potentially causing allergies, asthma, or lung diseases, posing a greater threat to those with weakened immune systems. Not only is it important to change pajamas frequently, but proper washing methods are also essential.

If high-temperature washing is not possible, using laundry disinfectants can be an alternative.
To suppress the growth of any remaining bacteria, using a high-temperature dryer or steam iron is also effective.
