So being allergic to exercise is an actual thing. Sure you may jokingly say you are allergic to working out because you don’t feel like hitting the gym, but there are actually people with a real condition that makes them allergic to exercising. It’s called exercise-induced anaphylaxis, and while it’s pretty rare – only about 50 in every 100,000 people have it – symptoms include flushing of the skin, hives, swelling and nausea. Worst case scenario: You can actually go into anaphylaxis and swell to the point you can’t breathe. Sadly, there’s no real rhyme or reason to it either. Some people get it based on the food they eat prior to exercise, while some people feel the effects after taking ibuprofen. Some women even experience symptoms when exercising during their time of the month. There is no specific amount of exercise or intensity that seems to trigger it either. You either get it or you don’t. In severe cases the allergy can be treated with an epi-pen, but most doctors say it’s manageable and doesn’t require you to avoid physical activity. There goes that excuse to quit the gym! (Cosmo)
