One day when I was in high school, I was in line at a coffee shop to grab my favorite iced coffee when a strange man told me, "Better be careful. That'll put hair on your chest." You've probably heard this idea before, but besides the fact that this theory was both creepy and unsolicited, it's scientifically false. Still, it made me second-guess my frapp order or mug of regular drip coffee for a while, because I genuinely had no idea how drinking caffeine was affecting my body. I'll admit, coffee does do some weird things to your body, but I feel pretty confident saying it won't put hair on your chest.
From improved vision to a high pain tolerance, coffee has so many health benefits that it should basically be classified as a superfood, in my opinion. But don't get discouraged if you don't notice some of these things after your morning cup. According to Grace Derocha, a registered dietitian, certified diabetes educator, and certified health coach at Blue Cross Blue Shield of Michigan, the effects of caffeine can vary a fair amount depending on different factors, like how dehydrated you are, how much or little you've exercised, the last time you ate, and even the amount of sleep you get.
Regardless, in honor of National Coffee Day, drink up and read about some of the cool, and sometimes weird AF things coffee can do to your body.
