8 Weird and extremely unusual allergies

World's most common allergies


In recent decades, medicine and science are really advanced but human health remained at the same level. Allergies are the leaders in the number of new forms of diseases. Statistics show that from allergies suffer even 25% of the population in the world. But, what are allergies exactly?

Allergies are actually a hypersensitivity disorders of the immune system. At the core of most allergies are immune processes that are activated by the entry of some uncomfortable substance or microorganism in the body. But if you wonder what cause allergies, there is a huge number of causes for allergies. Traditional allergens are viruses, drugs, bacteria, pollen, wool and food products. In the twentieth century among these factors can be added plastics, synthetic cosmetics, radio waves and artificial building materials. Every day there are more and more new allergens discovered. But sometimes even doctors can be surprised by the results and manifestations of allergies and by the unusual reaction to them.

Weird and extremely unusual allergies

Weird and extremely unusual allergies

Allergies can be manifested in different ways and there are many visible signs of allergies, such as painful and prolonged bouts of sneezing to watery eyes or to skin rashes. Rapidly developing allergic reaction may result in anaphylactic shock. We present you some of the most unusual allergies in the world!

Sun allergy

Spring is almost over, summer is coming. People can’t wait to show some skin and soak up the sun. But what about those people who get redness, rashes and even blisters from the sun? Sun allergy is very widespread and the reason for this reaction (called dermatitis or photodermatitis) is the effect of sunlight on human skin. Rays themselves have allergen, and irritation can be caused by other external or internal factors. External factors are all allergenic substances that accumulate on the surface of the skin – the pollen of flowering plants, cosmetics, essential oils. Under the influence of sunlight they cause an allergic reaction in the exposed areas of the skin. Internal factors usually are diseases and disorders of the immune system as well as the side effects of some drugs. All this increases the sensitivity of the skin to the sun and her vulnerability. The combination of ultraviolet rays and drugs can be extremely dangerous, causing severe allergic reaction. The symptoms are redness, burning and itching on the skin. Sun allergy can manifest in the swelling of the mucous membranes and the skin.

Allergy to water

We all know that water is life. Therefore, it’s surprising to hear that there are people who are allergic to water. Usually this disease occurs in a sharp drop in the water temperature, and is most common among people of Africa, India and other countries with hot climates. People there rarely have access to water, so when they get in contact with cold or hot water, their skin becomes covered with red spots and rashes. Similar but weaker symptoms may occur in long bathing in hot water. Although this type of allergy is quite rare, scientists have not yet discovered the real reason for this unusual effect of water on the human body.

Allergy to alcohol

There are also people who are allergic to alcohol and the allergy manifests as redness on the hands, face and body. The skin is covered with rashes and itches and in particularly severe causes may extend to strangulation. Most common case is intolerance of red wine and from this allergy suffer even 15-20% of people. This allergy is most often caused not by the alcohol itself, but the polyphenol compounds that are contained in beverages. Therefore it’s practically impossible to be allergic to vodka for example.But what is interesting is that the alcohol reduces allergenic properties of other food products. French doctors recommend that people who are allergic to strawberries, can drink wine while they eat.

Allergy to meat

Allergens in meat are specific and their impact decreases significantly after heat treatment. It is believed that the strongest allergens are chicken meat and pork. Beef and lamb cause allergic reactions very rarely, and most neutral is the rabbit meat. Recently, scientists found that allergy to meat is not as rare as previously thought. An allergic reaction is cause by the substance alpha-galactose contained in the meat of mammals. Upon consumption of the substance, the human body begins to produce antibodies. This reaction may occur 5-6 hours after a meal, and it is possible to get an anaphylactic shock.

Allergy to fish

This disease is quite common, especially in countries and regions where fish is a traditional food. About one third of patients have selective allergy to one type of fish. The others get side effects after consumption of various types of fish. Marine fish is much stronger allergen than the freshwater fish, and the caviar is also strong allergen. However, fish oil usually does not cause allergies. The human body can react badly on crab, lobster and shrimp.

Allergy to vegetables and fruits

Many fruits and vegetables can cause various allergic reactions. Most often these are tomatoes, citrus fruits, bananas, carrots, peaches, garlic and onions. It is interesting that the incidence of allergy to these products may be due to the climate and geographical location. Most allergenic fruits are apples, pears, peaches, cherries, apricot, walnuts, peanuts and chestnuts. Among the most dangerous vegetables are tomatoes, spinach, celery and parsley. Sometimes even cutting or holding kiwi fruit can cause a severe reaction in sensitive individuals. But here’s a comforting news – allergens from fruits and vegetables do not withstand heat and are destroyed by heat treatment.

Allergy to people

Nowadays we often hear someone saying that is allergic to some people, thus expressing his annoyance. But it turns out that this can be a real physiological problem. It was discovered that human scent, or the odor of sweat may cause allergy. Moreover, the male sweat causes many side effects. Similar reaction have been recorded for first time in the mid of the twentieth century.Then the scientists do not consider this as unusual, as environmental conditions were stable and there were no preconditions for the development of new allergies. Recently, however more and more women suffer from allergy to male sweat. According to researchers, this is due to the overall increase in the number of allergic diseases. This allergy is manifested by asthma attacks, fever, diarrhea, vomiting, edema, skin rashes, itching and sometimes even loss of consciousness and impaired blood flow to the brain.

Allergy to new technologies

Today we are surrounded by hundreds of objects that are the result of the technological progress. Our mobile phone, our laptop or the tablet, the TV and the microwave alleviate our life, but in some people can cause allergy. There have been registered case of allergic attack after two hours working on a computer. And this phenomenon has a scientific explanation. 5 of 15 people have an increased susceptibility or sensitivity to magnetic fields. Wireless devices such as Bluetooth, Wi-Fi and even ordinary mobile phone not just emit electromagnetic waves, but also create their own magnetic field. In more developed countries, the radio signals are found practically everywhere and the people who are allergic can’t live easily in such conditions. In the U.S. patients have had protests against the wireless internet. In Sweden, even those with increased sensitivity to electromagnetic waves are sent in special sanatoria entirely on government expense. However, this allergy is less widespread.
