In an unexpected move focused on environmental conservation, the French government has issued a recommendation that could change how fitness enthusiasts handle their post-workout laundry routine.
Earlier this year, France’s Ecological Transition Agency advised citizens to wear their exercise clothing three times before washing them, citing significant environmental benefits. The same guidance suggested wearing jeans up to 30 times between washes.
The recommendation comes as part of France’s broader environmental initiatives, highlighting how everyday habits like laundry contribute to resource consumption. According to the agency, excessive washing requires substantial water and energy while accelerating fabric deterioration, leading to faster clothing replacement and increased textile waste.
“Using the laundry excessively requires a lot of water and energy, and can also damage fabrics,” a spokesperson from the agency explained. “This can result in going through clothes faster and adds to the issue of textile waste.”
But this raises questions about hygiene, particularly for athletic wear that endures sweat-intensive activities. Health experts weigh in with nuanced advice, suggesting several factors to consider before extending the time between washes.
Dr. Michelle Laurent, a public health specialist, notes that fabric choice matters significantly. “Clothes made of natural fibers multiply fewer bacteria than synthetics, so cotton is generally a better choice than polyester if you’re planning to re-wear workout gear.”
The intensity of exercise also plays a role. Low-intensity workouts that produce minimal perspiration may allow for safer re-wearing than high-intensity training sessions that leave clothes soaked with sweat.
Seasonal considerations matter too. “Weather plays a significant role as temperature, humidity, and airflow all contribute to bacterial growth,” explains Dr. Laurent. “We generally sweat less in winter months, making it potentially safer to extend wear between washes during cooler seasons.”
However, health experts emphasize that personal factors should guide individual decisions. Those with skin conditions, compromised immune systems, or who naturally perspire heavily should wash their gear more frequently.
And this is just wild. For practitioners of contact sports like Brazilian Jiu-Jitsu or wrestling, not even a daily wash isn’t enough. These activities create ideal conditions for spreading skin infections like Staphylococcus aureus (staph), which can enter the body through minor skin breaks.
Staph infections can initially resemble ingrown hairs or pimples but tend to be more painful, red, swollen, and may develop a pus-filled center. Unlike minor skin irritations that improve with gentle care, staph infections typically worsen without treatment and may cause systemic symptoms like fever.
It’s truly something to behold when recommendations to limit machine washing get touted as a major environmental solution, especially when you consider the massive contributions from the real culprits—transportation and agriculture. So, by all means, let’s stop running the washing machine and avoid that 50 grams of CO₂ per load—while we continue to let cars and farms spew out tons of carbon into the atmosphere. Priorities, right?
