The World's Oddest Allergies


If you've ever joked that you're allergic to working out while huffing and puffing through a class at the gym, you're in luck: Both sweat and exercise are among a number of strange and unusual allergies that people actually have.

An allergic reaction happens when our immune system decides that some neutral substance, called an allergen, is actually harmful. As we inhale, swallow, touch, or inject, we take in allergens and our immune system responds by attacking.

Most of us are likely allergic to some degree to dust and pollen, but some have unusual allergies that few share.

Among them:

  • Cold
  • Hot
  • Estrogen
  • Water 
  • Chocolate (THE HORROR!)

There are more, too.

You can be allergic to pressure on your skin, a condition known as "dermatographic urticaria," in which the skin becomes raised and inflamed when stroked, scratched, rubbed, and sometimes even slapped.

You could be allergic to sex, which, in my opinion, is way worse than chocolate. Some women are actually allergic to semen, which brings burning in or around the genitals after sex, as well as swelling and itching.


You could even be allergic to your cell phone. Or at least the nickel in it.

Be thankful you aren't.

Do you have any odd allergies?  Heard of any you want to share?

My sister is allergic to nickel.  She literally has to paint the buttons on her jeans with nail polish to keep them from touching her slin.

My DH is actually allergic to gold.  So allergic that any gold in contact with his skin causes chemical burns.

Nickel for me. I get burns on my neck and fingers from jewelry. I finally gave up on earrings, the pain and reaction was just too much.

I swear to god I'm allergic to the cold. I break out in hives if I get to cold. But I have never been to a doctor and tested. I just wear alot of layers in the winter and stuff but whenever I come into a building my face is all in hives but it goes away pretty quickly.

DH is allergic to real gold...he gets burned from was a slight issue when looking for a wedding ring, because even whote gold would cause a reation after the rhodium started to wear off (which it does, I've had to have my rigs dipped twice in the 4yrs we've been married) we eventually found Tungsten...awesome it won't crush if anything happens, it will shatter...

I'm allergic to chlorine. If its in bleach i break out in hives. If its fumes it causes respiratory problems, like an asthma attack.

I'm allergic to red food dye.. makes me vomit in no time! I'm also very sensitive to dyes and fragrances in general. Orange peel gives me hives. I'm weird.
