You're pushing too hard. You should breathe through it, don't hold your breath. Look into getting a step for your feet. We're designed to squat, not sit, and getting your feet higher can get things to line up better internally
At work they had to put signs up to tell all the Indian workers who came to the UK not to do this as they were always breaking the loo seats! Better to get a step for your feet and get those angles better aligned.
I agree but I am also genuinely impressed how many serious answers are here. When I read the post I was sure it was just a troll, but troll or not, there are so many people here to give good and based advice. It's just great. We should keep it!
It’s a bit of a shock to see so many serious/informative comments near the top isn’t it? But it doesn’t detract at all from my overall enjoyment of the site. They’res still funny comments, just not always at the top. It would be wonderful if lemmy grew large enough to have active communities to match the majority of subreddits, but not too large that it becomes hateful and hive-minded.
Not so fun story: when I did my civil service in a hospital I once was called in a room from a patient, because the other patient from that room didn't come out of the toilet. I found her in the toilet. She had a stroke while pushing really hard. She had asked for a laxative for days, but the physicians didn't want to giver her one (don't know ow why).
Vagal tone, is the technical answer. A nerve (vagus) runs through your body and, among other things, slows the heart. When straining to "void", you cause that nerve to activate more strongly. It's also related to the Valsalva maneuver.
