Stranger than fiction: strange allergies you might not know about

Allergies can affect different people in different ways, and there are plenty of common allergies we all know about. You’ll probably be familiar with hay fever, asthma, and eczema, but what about the strange allergies in the world? From exercise to water, there are plenty of surprising things an individual can be allergic to.


All allergies can feel overwhelming if there’s a high risk of anaphylaxis, the life or death reaction to a trigger. But what if exercise-induced anaphylaxis? Unfortunately, this is a reality for some people and can trigger through physical activity. Usually caused by higher intensity exercise, in rare cases it can lead to an anaphylactic shock.

Symptoms of the allergy include hives, inflamed skin, and fatigue. Although these symptoms are uncomfortable, they are considered to be minor. Severe symptoms include difficulty to breathe or swallow, and wheezing, along with the aforementioned anaphylaxis. Treatment for the allergy is usually an EpiPen.


Water allergy (or aquagenic urticaria) although rare, with only an estimated 35 cases in the world, is a real thing and is difficult to navigate as humans require water to stay hydrated and wash. In as little as 60 seconds after exposure to water, the skin can break out in a rash.

It is usually inflamed and itchy, and can cause the skin to feel uncomfortably hot. It can even be triggered by sweat or tears. Although treatment in the form of antihistamine is common, there is only so far this will go in cooling the effects of this awkward allergy. Unfortunately, the cause is a mystery, but it’s thought to be a reaction to substances in the water.


Believe it or not, some individuals are allergic to sunlight. While the UK try to soak up every sunbeam come summer, for some people this isn’t possible. The condition, known as polymorphic light eruption, is a surprisingly common allergy that results in itchy rashes that can last to up to three days and can take two weeks to heal. Estimates say the allergy affects 10-15% of the UK.

The cause of the allergy is possibly due to the UV light altering a substance in the skin which causes the immune system to react negatively. Unfortunately, there is no known cure for the disorder and treatment includes sunscreen, avoiding the sun especially between 11 am to 3 pm, and wearing long sleeves and trousers.

The odds of you having one of these strange allergies is extremely low, but you never know what you could be allergic to. We highly recommended testing for allergies so that you don’t risk any of the symptoms mentioned, allowing you to live comfortably.
