The human body can get up to some weird stuff, including something called "sad nipple syndrome."
There are a lot of different ways our body reacts to stimuli and not all of them make sense, whether it's sneezing when we look at a bright light, our fingers wrinkling when they get wet, or that weird full-body jerk that happens sometimes when we're about to fall asleep. One specific way called "sad nipple syndrome" is going viral on TikTok right now and has many people wondering if they also have this phenomenon happening to them.
