This is a little gross. If you don’t want to read about my sweat, you might want to skip this entry.
As I’ve mentioned previously, I’ve reluctantly taken up running. I run 5 km three or four times a week. When I get home from my run, I often have the oddest ammonia smell in my nose. It’s not like you can smell me across the room or anything, but I’m definitely aware of it.
After noticing this two or three times, I was all ‘what gives, body? Why do you smell like Windex?” So, I asked the Internet. This seemed to be the most cogent explanation:
The smell of ammonia in sweat is common among runners. Ammonia comes from the breakdown of amino acids (the building blocks of proteins) within the body. It is made up of nitrogen and hydrogen. The hydrogen atoms are converted to glucose and used as fuel. The nitrogen is a waste product that needs to be excreted by the body, and is processed in the kidneys to form urea that is excreted in urine. If there is too much nitrogen for your kidneys to deal with, it will be excreted as ammonia in your sweat.
So how does one address this peculiar issue? From another article:
The key to avoiding that ammonia smell is to ingest sufficient carbohydrates. If you eat an ample amount of carbohydrate with every meal, then you should have plenty to fuel your exercise activity. Even people who work out on an empty stomach should have some glucose in their bloodstream upon rising – unless they subscribe to the myth that cutting out carbohydrates before bed helps you lose fat. If you find that the ammonia smell persists (even when you consume carbohydrate with every meal), try having a low glycemic carbohydrate before you workout.
A little oatmeal, a small apple, or even a piece of sprouted grain bread can provide the fuel that your body needs. Remember, your body requires fuel to burn fat! So don’t think that providing some carbs before cardio is going to eliminate the fat burning process.
And here I thought the only side effects from exercise would be looser-fitting clothes and smugness.
