Hotspot #1: Water Fountains
Studies have found that water fountains can actually harbor more bacteria than toilets, as their wet surface makes them a breeding ground for germs. The basin is most likely to be contaminated, but the handle may also contain some nasty microbes.
The safest way to hydrate is to bring your own water bottle. If you must use the fountain, follow these precautions: Turn it on for a few seconds before drinking from it, don't let your mouth come in direct contact with the spigot, touch only the handle and wash your hands afterward.
Hotspot #2: Locker Rooms and Showers
Germs thrive in wet, humid areas--putting locker rooms and showers right in the danger zone. The biggest threat is Methicillin-resistant Staphylococcus aureus (MRSA), a bacterium that can cause skin infections. Showers can also pass along warts, ringworm, strep, athlete's foot and other not-so-fun fungi.
The best way to stay safe is to shower at home—but if you must lather up in the locker room, wear flip-flops to avoid coming in direct contact with floor-dwelling microbes (and to prevent slipping). Other best practices include bringing your own antimicrobial soap and shampoo, drying your feet thoroughly after showering, and wearing a towel when sitting in the steam room or sauna.
Hotspot #3: Yoga Mats
Next time you're doing crunches or settling into your favorite stretch, consider that your exercise mat most likely absorbed the sweat and germs of whoever last sweated on it. The best precaution is to bring your own mat. If you must use a shared mat, wipe it down with a disinfecting spray before and after each use, and place a towel on the mat as an extra germ barrier.
Hotspot #4: Cardio Machines
Treadmills, ellipticals and stationary bikes are great for burning calories, but the trade-off could be a burning fever later. To reduce the threat, use hand sanitizer after your workout. Most gyms provide sanitizing spray to wipe down machines before and after each use.
Hotspot #5: Weight Machines & Free Weights
As people do full-body exercises with shared weight machines, there's a bigger chance of spreading germ-filled sweat. Again, sanitizer is the best defense: Spray down and wipe each machine before and after each use, and apply hand sanitizer between sets.
Hotspot #6: Gym Bags
In addition to clothes and gear, your gym bag could pick up some unwelcome passengers—like E. coli, Norovirus and staph—through contact with benches and floors. To prevent this, choose a bag in a material that's less germ-friendly, such as plastic or vinyl, and wipe it down with disinfecting spray when you get home. Store sweaty clothes in a separate plastic bag.
Hotspot #7: Towels
Even if the gym's towels have been washed, they could have picked up bacteria or viruses from baskets, benches or lockers. To stay clean, dry and germ-free, bring your own towels from home: One to absorb sweat during workouts and another if you're showering.
