3. The Risks of Waiting Too Long
Pajamas sit close to your skin for 7–9 hours a night. If you wait too long to wash them, you are essentially sleeping in a cocktail of:
Dead skin cells: Humans shed millions of skin cells every night.
Body oils and sweat.
Microorganisms: Bacteria like Staphylococcus can build up on the fabric. While usually harmless, they can cause infections if they get into small cuts or pores.
4. Tips for Staying Fresh
Shower before bed: If you go to sleep clean, your pajamas stay clean longer.
Air them out: Instead of folding your PJs and putting them under your pillow immediately, hang them up to air out during the day.
Choose Cotton: Natural fabrics like cotton breathe better and hold onto fewer odors than synthetic materials like polyester.
The Verdict
The person in the post washing weekly is on the edge of “too long,” while the friend washing daily is likely doing more laundry than necessary (unless they sweat heavily). For most people, changing your pajamas every 3 days is the perfect balance between hygiene, skin health, and being eco-friendly with your laundry habits.
