Pajamas may feel clean after just one night, but professionals say they’re one of the most overlooked sources of bacteria in your home. Because sleepwear absorbs sweat, body oils, and dead skin cells for hours every night, washing them the right way matters more than most people think.
Here’s what laundry and hygiene experts recommend:
How Often Should You Wash Pajamas?
Professionals agree:
Every 3–4 wears if you shower before bed
Every 1–2 wears if you sweat at night or don’t shower before sleeping
After every wear if you’re sick, have sensitive skin, or sleep in warm weather
Wearing pajamas too long can allow bacteria, yeast, and allergens to build up—leading to skin irritation and breakouts.
Choose the Right Water Temperature
Warm water (30–40°C / 86–104°F) is best for most cotton pajamas—it cleans effectively without damaging fabric.
Hot water should be reserved for illness or heavy sweating, as it can shrink fabric and fade colors.
Cold water is acceptable for delicate or silk pajamas but may not remove oils as effectively.
Use Less Detergent Than You Think
Overusing detergent leaves residue in fabric, which can trap bacteria and irritate skin. Professionals recommend:
Measuring detergent carefully
Using mild or fragrance-free detergent for sleepwear
Avoiding fabric softener, which coats fibers and reduces breathability
Turn Pajamas Inside Out
This allows detergent to better clean the areas that touch your skin most, removing sweat and oils more effectively.
Don’t Overload the Washing Machine
Overcrowding prevents proper rinsing. Pajamas should move freely so detergent and water can do their job.
Dry Them Completely
Damp fabric encourages bacterial growth.
Tumble dry on low heat or
Air-dry in a well-ventilated space
Avoid leaving pajamas in the washer after the cycle ends.
Store Pajamas the Right Way
Only store pajamas once they are fully dry. Fold them neatly and keep them away from humid areas like bathrooms to prevent mold and odor buildup.
The Bottom Line
Clean pajamas aren’t just about comfort—they protect your skin and sleep quality. Washing them correctly helps reduce irritation, bacteria buildup, and unpleasant odors, keeping your nights healthier and more restful.
