Allergies are common problems. Usually the allergies you suffer from are very common, of which there are thousands if not millions of cases in the world. But there are those who suffer from rather unusual allergies: here are the 10 strangest ones.

WATER ALLERGY

This type of allergy affects one person every 23 million, and sufferers often cannot leave home. The reason would be a hyper-sensitivity to ions present in non-distilled water. The young Ashleigh Morris suffers for example: the only contacts with the water are only short (and for her very painful) showers.

WOOD ALLERGY

Some are allergic to specific types of wood or wood dust, but some are allergic to any type of wood: it is a very debilitating condition, since wood is a widespread material and used for all kinds of objects. The Englishman Dan Hill discovered that he had become allergic to wood shortly after he quit his job as a carpenter.

EXERCISE ALLERGY

It seems the classic joke for those who are lazy, but in the world there are about 1,000 people who suffer from EIA (“Exercise-induced anaphylaxis“), and it is usually combined with other pre-existing allergies, which amplifies the effects in case of physical effort, with potentially very serious consequences.

APPLE ALLERGY EATEN NEAR BIRCH TREES

The young Grace Morley has a decidedly unusual allergy, which combines not only what sheeats but also where she eats it: she can’t eat apples near birch trees. Normally, eating apples or staying close to the birch trees does not have any negative effects, but if it combines the two, it risks a severe anaphylactic shock that could even be fatal. Apparently, the cause is the combination of substances contained in birch pollen with other substances contained in apples.

ALLERGY TO UNDERWEAR

This type of allergy can cause severe skin irritations: the cause is typically in the tissues (and chemical dyes) used for the production of underwear. Usually, the use of high quality clothing solves the problem. In 2007, after being photographed several times without underwear, Britney Spears explained that she suffered from this allergy .

SUN ALLERGY

Sun

Feeling uncomfortable in the sun is not unusual, but there is a particular type of suffering, called “Solar Urticaria“, which is very rare and suffers from a handful of people around the world. Contact with sunlight in these subjects causes severe irritation, which also affects areas of the body that are not directly affected by sunlight.

SEX ALLERGY

Some women are allergic to their partner’s seminal fluid: in some cases, anaphylactic shock can even lead to death. There are only 100 confirmed cases in the world : the treatment is rather complex, and also requires regular sexual relations between the patient and the partner, to strengthen the immune system.

ALLERGY TO YOUR CHILD

36-year-old  Joanne Mackie began to suffer from painful redness and even blisters shortly after giving birth to her son James. The pain was so strong that he could not hold the baby in his arms, unless he used a cloth to not touch it directly. The allergy was traced to a form of  pemphigoid gravidarum.

ALLERGY TO TECHNOLOGY

The English Debbie Bird is particularly sensitive to electromagnetic fields, so widespread today because of modern technologies: wi-fi, cell phones, computers, but also microwave ovens. The woman can have painful skin irritations and her eyelids swell if she gets too close to a spring. To protect himself, he also had to make a Faraday cage around the bed so he could sleep soundly. His case is very controversial, because it ended up at the center of the debate on the harmfulness or otherwise of electromagnetic fields: his condition, however, would not be representative of the effects on average people

ALLERGY TO KISSES

The kisses (we speak of those “passionate”, a kiss on the cheek almost never hurts) can cause irritations of various kinds, but the most serious effects occur when one of them suffers from a serious form of food allergy. In 2003, the then seventeen-year-old Jamie Stewart risked death after kissing a friend at a party: Jamie was suffering from a severe peanut allergy, and she had just eaten peanuts.
