Allergies are an increasingly common affliction and can range from mild to life-threatening. The most common allergies are usually food-related, but some are incredibly rare. 

Some of the rarest allergies may not be caused by an environmental trigger but by a person’s immune system. These allergies are known as auto-immune disorders and can be difficult to diagnose. 

No matter what the cause of the allergy is, all can be life-altering. In this article, we will explore the five rarest allergies in the world and how they can be managed.

1. Water

Aquagenic urticaria is a medical condition where people develop itchy and painful hives when their skin comes into contact with water. The hives are caused by the body’s mast cells releasing histamine, which causes the skin to react. The severity of the reaction does not change with the temperature of the water, and there is no cure, although some treatments, such as creams and lotions, can help soothe the itching.

2. Sunlight

Solar urticaria is an allergy to sunlight that can cause a person to break out in hives. When exposed to the sun, the body’s mast cells release histamine, making the skin red and itchy. To avoid this reaction, it is important that exposure to the sun is limited and that antihistamines and sunscreen are used to minimize the effect. 

Unfortunately, there is no known cure for this condition, although it can sometimes resolve independently. It should not be confused with heat urticaria, a separate allergic reaction that occurs when the body is exposed to extremely high temperatures.

3. Money

If you have an allergy to nickel sulfate, you may overreact to certain objects containing nickel. You should avoid contact with these objects, such as jewelry, metal clothing parts, hair pins, lighters, and even some door handles. It is also important to wear gloves when you have to handle money and avoid carrying loose change in your pocket.

4. Exercise

For those suffering from exercise-induced anaphylaxis and urticaria, it is important to know that regular exercise may be impossible. Anaphylaxis is an extremely rare and severe allergic reaction triggered by physical activity, leading to hives, gastrointestinal issues, and even anaphylaxis. This is a life-threatening condition, so sufferers should exercise with a partner and carry an adrenaline shot to be taken in case of emergency. Although regular exercise is encouraged for a healthy lifestyle, those with anaphylaxis must take extra caution regarding physical activity.

5. Human Touch

Dermographism is a skin condition that causes an allergic reaction when someone’s skin is touched. When someone with this condition is touched, the skin will swell up, creating a raised mark or rash. This reaction can be so severe that it can cause a person to write on their skin. Treatment for this condition includes taking antihistamines to prevent the histamines from causing swelling.


The world of allergies is incredibly vast and varied. While the most common allergies, such as pollen and pet dander, may affect many people, some rarer allergies can be found worldwide. Despite their rarity, these allergies can be incredibly disruptive to the person affected and should be taken seriously. Those affected can lead full and active lives with proper diagnosis and management.
