UTIs occur when harmful bacteria (such as E.coli) travel up your urethra and multiply. Bacteria can flourish when you go too long without changing your underwear or wear ones made of synthetic materials like lycra or nylon.

If you’re prone to UTIs, it doesn’t hurt to take precaution when selecting your underwear and lubricant.

Thongs: due to the cut, all it has to do is move an inch or two and any bacteria you may have back there is now right next to the vagina and urethra. If you choose to wear thongs, opt for cotton ones and avoid wearing during physical activities as they tend to shift.

Lycra, nylon, lace and polyester: these synthetic fabrics don’t “breathe” and can trap moisture and bacteria inside the panties. Avoid wearing all together or for long periods of time.

Shapewear: if a certain occasion lends to wanting to wear shapewear, don’t let it stop you from going to the bathroom and urinating frequently! Wash after use and try not to wear regularly!

Cotton undies: cotton wicks moisture away from the skin and when your genital area is kept dry, bacteria is less likely to grow, which lessens the risk of a UTI. Make sure they don’t fit too tight and change daily and after workouts!

Commando when you can: when it’s time for bed, let your vagina breathe! Go full-on commando or wear loose-fitting, breathable pajama bottoms.

It’s no secret that sex is a leading cause of UTIs, but there are ways to minimize risk with your condom and lubricant choices. The data regarding the use of lube during sex leading to UTIs is less consistent than the data involving the use of condoms, but some people argue that certain types of lubricants can contribute to UTIs.

Spermicide-coated condoms: data has shown that spermicide is harmful to “good bacteria” in the vagina. Make sure you check the ingredients list before you use!

Unlubricated condoms: this increases friction during intercourse, which can lead to inflammation of the urethra.

Lubes containing glycerin: glycerin (a sugar) encourages the growth of bacteria which can lead to UTIs. You may want to avoid lubricants which contain glycerin, or any other forms of added sugar.

Oil-based or water-based lubes: studies show mixed opinions here — some argue that natural oils such as coconut oil are a good substitute for lubricants, while others say that oil seals bacteria into the vagina. In general, it is safer to stick to water-based lubes when you can.

It's important to note that not all lubricants are compatible with condoms. For example, oil-based lubricants can dissolve latex condoms.

With all this in mind, it’s important to remember to find a solution that works for you!

Every person (and body) is different; however, a good general rule of thumb is to avoid synthetics as much as possible and practice good hygiene, especially after any physical activities.
