What does sun allergy look like

The sun is an object of desire for many Poles. Unfortunately, in our climate zone we suffer from a lack of sunlight. In autumn and winter, the days are often gloomy, which negatively affects our mood. No wonder that when the sun finally comes out, we want to take full advantage of its benefits. Unfortunately, not everyone can afford it. What does sun allergy look like? Sun allergy is a problem that affects more and more people every year. Both the sun's rays and some chemicals that interact with the sun can contribute to these troublesome symptoms. What to watch out for when exposing your skin to sunlight ADVERTISING In the case of sun allergy, we are dealing with an overactive immune system that misdiagnoses the threat. As a result, it starts combating substances that pose no real threat to it, e.g. pollen. Depending on what causes the allergic reaction, there are several types of allergies. When annoying symptoms appear during the first contact with the sun, for example on the first day of sunbathing on the beach, we are dealing with idiopathic photodermatosis. Sometimes, however, chemicals are at the root of troublesome symptoms. In the case of exogenous photodermatosis, i.e. having its cause in the external environment, there are phototoxic and photoallergic reactions. Idiopathic photodermatosis makes itself felt during the first prolonged exposure of the skin to sunlight. After winter, we have pale skin, which means that it lacks melanin, which is a natural dye that protects the skin from sunburn. Idiopathic photodermatosis can take the form of solar urticaria, summer scabies, and herpes simplex. Generally, the phototoxic reaction results from our ignorance. It can be prevented very easily by avoiding sun exposure after taking certain medications or herbs. Do not spray perfume on your body before going to the beach, as it may react with the sun. You should not sunbathe if you take antibiotics, use hormonal contraception or relieve pain with painkillers. It is also inadvisable to consume infusions of St. John's wort. The substances contained in this herbal material increase the risk of a phototoxic reaction. What is the difference between a photoallergic and a phototoxic reaction? To see the difference, the immune system is not involved at all in the phototoxic reaction, while it plays a key role in the photoallergic reaction. In the photoallergic reaction, the photohapten has contact with the skin, its spatial configuration changes under the influence of sunlight. The altered molecule attaches to the protein to form a hybrid that the immune system treats as a stranger and triggers a cascade of defense responses aimed at annihilating the "enemy". The immune system produces antibodies, which means that each subsequent contact with the photohapten will lead to an allergic reaction. The substances that may participate in phototoxic reactions include some drugs, including sulfonamides, fragrances, e.g. musk ambergris and plant compounds - many of us are not aware that garlic contains diallyl disulfide, i.e. a potential photohapten. the sun suffers from vitiligo because their skin does not produce a natural protective barrier in the form of melanin. They should absolutely avoid strong sun, and when in the open air, protect their skin with SPF 50 sunscreen. The sun is also a huge threat to patients with lupus erythematosus and porphyria. A light, Slavic complexion also predisposes to sun allergy.
