Getting anesthesia is a great way to endure difficult medical procedures without having to be awake for the whole ordeal. It's like magic, really. But the creepy things that happen to your body under anesthesia might unnerve a lot of people outside the medical community. Still, it's much better than trying to get through a long surgery without any help. Even if it does some weird things to the body, I'll take anesthesia over the alternative any day.
First, though, it's important to remember that going under anesthesia is very different from just taking a nap for a couple hours. Although it may just feel like going to sleep for the patient, there's a lot more going on. The body goes into a sleep-like state, sure, but general anesthesia prevents the brain from responding to pain or reflex signals, according to the Mayo Clinic. To make sure there aren't any complications, the anesthesia care team monitors the patient during the whole procedure, and in fact going under general anesthesia is considered safe even for many patients with serious medical conditions, as further explained by the Mayo Clinic. However, even in this deep sleep-like state, there's still a lot of action happening in the anesthetized body.
