I just got off a nasty bout of viral fever that had me down for about a week. I was puking every now and then, and after each session I’d be totally exhausted, and feel completely drained out (no pun intended). This feeling would last for about a minute or so, and then I’d go back to feeling miserable.
So how come vomiting is so damn exhausting?
I always understood it to be because you are expending a good deal of energy while you are suspending breathing. And when you try for a full breath, it’s interupted again. Add in the fact that you are in poor health/ weakened condition and possibly dehydrated during many illness/conditions that lead to vomitting and you have the recipe for being exhausted.
One thing I always found ‘cool’, was that one actually starts beading sweat before episodes…as the body prepares for a pre-emptive cool down. That takes energy too.
I wonder how much easier it’d be to puke hanging upside down from gravity boots. Seems like it you didn’t have to throw up first that the effort required would be appreciably lessened.
Well, in that case you would probably choke. With an involuntary action your body is not going to learn that it does not need to use the same amount of force as before, and then you have to deal with vomit in your sinuses.
