Have you ever taken a dump that made you feel like you’d just slept for 12 hours?
You bet we have, Ryan. And we call it “poophoria,” as do some gastroenterologists, a fun bunch. Here’s one likely explanation from Neil Stollman, of the East Bay Centre of Digestive Health. He says a large bowel movement causes distension of the rectum, followed quickly by decompression. This may stimulate the vagus nerve, a command centre that modulates many of our bodily functions. Next, your blood pressure and heart rate drop slightly, which can make you feel lightheaded or even euphoric. But mind the plop: the effect has caused some to pass out mid-evacuation; it’s called defecation syncope. Sounds like a good story to tell the kids.
