How Often Should You Replace Your Panties?
When considering how often to replace your panties, two main factors should guide you: hygiene and personal comfort.
Hygiene: The Essential Factor
Philip Tierno, a professor of microbiology and pathology at New York University, highlights that even after a thorough wash, your panties can still harbor bacteria. This is because your panties are in constant contact with skin that may contain E. coli. While regular washing reduces bacterial presence, it doesn’t eliminate it entirely. According to Dr. Charles Gerba from the University of Arizona, a typical pair of washed panties might still contain about a tenth of a gram of fecal matter.

Fortunately, these bacteria aren't a major health threat as long as you wash your panties regularly. The recommended practice is to wash panties after every wear. Ideally, use hot water and bleach for optimal sanitization. If the fabric can’t handle hot water, a detergent with peroxide in cold or warm water is also effective. Additionally, drying your panties in the sun can help sanitize them due to the UV rays.
Replacement Frequency
For panties that you wear regularly, it’s generally a good idea to replace them every year. However, Tierno mentions that with proper care, panties can last longer. If the elastic remains intact and there are no holes, your panties can be worn until they start to show signs of wear.

Signs It's Time to Replace
Laetitia Lecigne, Jockey’s creative director, suggests looking for signs like loss of stretch, poor fit, and aesthetic degradation. Sagging, drooping, or deformities indicate it’s time for a new pair. Even if unused, the spandex and elastics in panties can degrade over time, losing their stretch and recovery properties.

Laundry Habits Matter
The lifespan of your panties is influenced by how often you wear and wash them, particularly in high-activity situations like workouts. Proper washing and timely replacement will keep your panties in good condition.

For optimal hygiene and comfort, ensure you wash your panties regularly and replace them when they show signs of wear. This will keep you feeling fresh and comfortable every day. Visit Souszy for a wide selection of high-quality panties designed to provide lasting comfort and support.
