If you still get maxed out, you should clean the toilet seat with an alcohol-based wipe before you sit down. David Jay Weber, an epidemiologist and doctor at the Gillings School of Global Public Health, University of North Carolina, Chapel Hill. You can also lay out the seat with toilet paper, but try not to touch the seat – and remember that the paper you use to trim the seat may also contain germs since the toilet was flushed the last time, probably aerosol Germs from the toilet into the air that may have been deposited on the paper you are using.
What about squatting? Research suggests that most women prefer to squat over a toilet seat to avoid germ and urine exposure. However, some doctors fear that this position can make it difficult to completely relax the pelvic floor, which can be a risk. For example, some research suggests that squatting women may take longer to urinate their urine than release all their urine, which may increase the risk of urinary tract infections. But in healthy people, these risks are likely to be low, Dr. Doreen Chung, Urologist at the New York Presbyterian / Columbia University Irving Medical Center. And it's much better to squat than to give up the toilet, she said. "There are patients who hold their urine and are then unable to relax their pelvic floor muscles to urinate," she said. But if you squat, be nice and clear up when necessary. (Ladies, you know what I'm talking about.)
Wash and dry your hands and do not touch anything.
It is very important to wash your hands afterward to use a public bathroom – they inevitably become germinated by the touch. For example, a study from 2011 found fecal germs on bathroom handles in the public bath and skin-related bacteria, including staphylococci and streptococci, on bathroom doors, stall doors, faucet handles, and soap dispensers. But many people either do not wash their hands or do it right. "There are areas that people miss, like the back of the fingertips," Dr. Matthew Zahn, Chairman of the Public Health Committee of the Infectious Diseases Society of America. Dr. Weber suggested washing with water at a comfortable temperature for at least 15 seconds, so you're in no hurry.
However, think twice before turning off the faucet with the hands you just washed. "This is probably the dirtiest place in the bathroom," Dr. Judy Stone, a Maryland-based infectious disease doctor – they all turn the tap on with dirty hands. Instead, consider drying your hands with a paper towel, and then use this towel to turn off the faucet. (If it's an automatic faucet, congratulations: you've just won the lottery.) If there are no paper towels, use toilet paper or an alcohol swab if you have one.)
