Los Angeles Dodgers pitcher Rich Hill has been dealing with a troublesome blister all season long, and he has tried everything to cure the ailment, including peeing on his hand. The above Tweets went viral, and everyone is grossed out by Rich Hill admitting to pissing on his hands, but the reality is baseball players have been urinating on their hands for quite some time. This article from 2012 published by Gizmodo quotes several major leagues, including Moises Alou and Kerry Wood, discussing peeing on their hands to treat blisters. Urine is 95% sterile, with the only chemical being present is urea, a nitrogen metabolite which is actually used in several hand creams meant for treating skin (after being synthesized in a lab, don’t worry, nobody is peeing in your Aquaphor). So while peeing on your hands consistently could alter your hands, it’s more likely to soften the skin, and eliminate callouses than treat blisters under the skin. Also, creams that have urea in them have more of it than what’s in your urine, so you are better off using a cream than peeing on your hands if you are convinced urea is the cure for your blisters. However, baseball players are a superstitious bunch, and you can expect players to continue pissing on their blistered hands for the foreseeable future. Science, from SportSmasher.com.
