When you got a #2 brewing, and you start sweating, it's normal!
You ever sit down and have to quickly take all your clothes off because you cant stop sweating for whats about to go down in the restroom? It happens to all of us.
This is because theres swelling and inflammation in the colon, probably from that big burrito you just ate, and your immune system raises the temperature in your body. If this has ever happen to you, you know that when it passes, you cool down almost immediately.
