The next time you head to the gym or a yoga class, think about taking along your own floor mat for workouts. The rubber or vinyl mats provide cushion when doing sit-ups or yoga stands. But the mats are also potential incubators for bacteria and other germs.

Many gyms and aerobics classes provide mats for students. But think about it. Dozens of different people use the mats each day with sweaty hands and feet. Although many gyms ask patrons to wipe equipment and mats off after each use, many people don’t.

Experts say viruses and bacteria can survive for up to 2 hours on the surface of everyday objects like door handles, countertops and, yes, your exercise mat.

The gym or workout room is the perfect (hot and humid) environment for harboring germs, bacteria and viruses. Some facilities provide anti-bacterial spray or cleaners for members to clean the equipment after each use. Cleaning and sanitizing procedures for yoga mats vary. Some gyms spray mats daily, while others spray daily with a weekly washing. Ask the attendants how often the mats are sanitized.

If you aren’t sure about your gym’s cleaning regimen or you want to take additional precautions against spreading germs, you can:

• Take your own mat
• Take sanitizing wipes and clean mats prior to using them
• Wear gloves and socks
• Take a long, thick beach towel to place over the mat
