For sure, if and when people aren't wearing underwear made from natural fibers, it can trap body odor more and create more heat, which means more sweating. So, if you don't already wear underwear made of natural fibers, that would be a thing to try.
You might also want to just try hydrating more and just check in with your general health and self-care. For example, if you've been eating poorly, your body may be reacting to that.
Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has. - Margaret Mead
