A recent study inspired headlines and tweets the likes of “drinking young people’s blood could help you live longer and prevent age-related diseases.” We at Popular Science would rather you not do that. Here are several arguments against drinking human blood.
Drinking human blood can make you very sick
For starters, a lot of blood you’ll encounter on the street carries some kind of pathogen. Drinking infected blood is a great way to get your very own infection. And unlike animals who’ve evolved to live on blood, humans can actually wind up with iron overdoses if they overindulge.
There are people feel compelled to drink the blood of others, and even follow rules to make sure they’re doing it safely and consensually. Some of the people who do this feel they have a genuine medical condition that is improved through the drinking of blood, but it’s important that you discuss these symptoms and feelings with your physician. And you definitely shouldn’t just take a shot of the first blood you’re offered.
