If you can’t recall the last time you changed out your bath towels, it’s probably been too long. While you likely don’t change it daily, it’s crucial to understand the hygiene importance. So, should you be changing your towel after just one use? We asked health experts for insight on when it makes sense to swap it out.
Why You Need to Wash Your Towel to Begin With
Your towel does more than just help you dry off—it acts as a secondary cleaning tool. “The friction helps exfoliate your skin and removes any residues that didn’t wash off in the shower,” explains Ryan Sinclair, PhD, MPH, a professor of environmental microbiology at Loma Linda University. This means that your towel picks up skin cells, natural bacteria, and even fecal bacteria from the shower, which can transfer onto your body. “The towel essentially becomes an incubator for bacteria to multiply, as it provides a warm, moist environment with an abundant food source from your skin oils and cells,” Sinclair says.
When You Should Change Your Towel After One Use
The science behind towel changing is complex, with several factors at play. Humidity and airflow are critical elements. “If your bathroom remains steamy, your towel stays damp, creating an ideal breeding ground for bacteria,” Sinclair explains. “A towel that dries within two hours is much safer than one that stays damp for six.” To help towels dry properly, you should spread them out as much as possible.
For most healthy individuals, changing your towel every three uses is reasonable, as long as you allow it to dry completely, suggests dermatologist Michelle Henry from Skin & Aesthetic Surgery of Manhattan. However, there are instances where you should change your towel after a single use: “Any time there’s an infection, towels should be washed daily,” Henry adds. This includes cases of skin infections, colds, flu, or norovirus. Additionally, if you have compromised skin due to conditions like eczema or cuts, using a fresh towel each time is recommended. And naturally, if the towel becomes soiled, you should replace it immediately.
Summary
Understanding when and why to change your bath towel is crucial for maintaining hygiene. While it’s typically safe to reuse towels up to three times if properly dried, there are certain circumstances—such as infections or compromised skin conditions—where you should switch to a fresh towel after every use.
