We’ve all had to deal with the coughing, sneezing, itchy eyes, a rash or some other skin irritation, and maybe even hives. And for what? Usually do to some substance that our body is allergic to, causing annoying and sometimes painful symptoms.

It’s safe to say that most people are allergic to something. Whether it be pet dander, dust, chocolate, or that lovely yellow powdery substance we like to call pollen, most people have to deal with being allergic to one thing or another. Being allergic to dust or pollen or certain types of foods seems common these days, but can you imagine being allergic to something else? Say…the sun? Here’s a list of the top ten oddest allergies.

5. Computers – Electromagnetic Hypersensitivity

Allergies to computers seems almost impossible these days, and even more impossible to imagine. However, computer users have complained or nasal congestion, sneezing, itching, and even headaches after using the computer. Studies have found that computer monitors and other parts contain a chemical called triphenyl phosphate, which is used as a flame retardant. Fortunately, levels of the chemical usually decrease after the computer is used for a longer amount of time.

4. Exercise – Anaphylaxis

You’ve probably heard someone joke and say that they are allergic to exercise out of the mere cost of being funny and probably lazy. However, there is in fact a real allergy that makes some allergic to exercising. Only 1,000 people are said to have the allergy. Called exercise-induced anaphylaxis, this allergy is only noticed after someone eats a certain type of food, say peanuts, and goes to exercise. That person can easily eat peanuts without having a reaction, but when exercise is added, the person may experience fainting, vomiting and difficulty breathing.

3. Cold – Familial Cold Autoinflammatory Syndrome

Not many people love being in the cold, but imagine being allergic to it. Known as familial cold autoinflammatory syndrome (FCAS) or simply cold urticaria, this allergy is caused by cold temperatures. The cold weather will trigger the body to release histamine in the skin which causes rashes, hives, redness, and swelling. This condition can be deadly, especially if undiagnosed, as most people may at times swim in a cold pool or take a cool shower. Both of these can cause the body to go into shock.

2. Sun – Erythropoietic Protoporphyria

It is very rare that people are allergic to the sun, but the allergy does exist. It is said that only 300 people in the world are allergic to the sun. It’s medically known as solar urticaria. There is also a more serious condition known as erythropoietic protoporphyria. When exposed to direct sunlight, the immune system activates inflammatory cells that are within the skin. Most people allergic to the sun are told to limit their exposure and to wear sun block. Others need to wear special clothing or avoid the sun at all costs.

1. Water – Aquagenic Urticaria

Known as aquagenic urticaria, this condition is said to only affect one out of every 23 million people in the world. Being allergic to water is extremely rare, and most that are allergic to it are confined to their homes. Being allergic to water means being allergic to sweat as well as tears, and even allergic to foods that contain water, such as juices, tea, and coffee. This means that bathing and showering are extremely difficult. The person is hypersensitive to the ions found in non-distilled water, so most have to be very careful when drinking water, or they drink non-distilled water. Here is an article from an actual case of aquagenic urticaria
