Spring is a difficult season for people with sensitive bodies. Troubles may appear on the skin, especially on the face, which is more common and prone to allergic dermatitis. Because the body’s metabolic capacity gradually increases in spring, the sebaceous glands secrete more and more, and the skin is changing itself. During this period, the skin is very sensitive, and if you do not pay attention to protection and maintenance, you will suffer from dermatitis. Spring allergies are mostly seen in people with allergies, and are especially common in young and middle-aged women. If these damaged cells are not repaired in time, they will continue to divide into skin cells with poor immunity and incomplete sebaceous membrane secretion, resulting in various sensitive skin problems and many sequelae. Therefore, skin allergies should be treated promptly and suitable care should be taken in daily life.
(A) Factors causing atopic dermatitis
1, ultraviolet radiation. The skin is less resistant in spring and is most susceptible to allergies. The ultraviolet rays in the sun enhance in spring, and the skin is allergic to the ultraviolet rays in the sun, which can easily induce solar dermatitis. In addition, the cosmetics applied to the face are also prone to skin allergies after sun exposure and changes in temperature rise. Throughout the year, the UV content of the sun is the lowest in winter, and people seldom move outdoors, while in spring, the UV content in the air increases, and the skin receives sunlight with high intensity and long duration. In winter, the human body has adapted to a low UV environment, and when it enters spring, the skin cannot adapt at once, and the sensitivity to UV rays increases, and the epidermal cells of the skin are more vulnerable to UV rays than in winter. Injury, prone to inflammation, produce degeneration, decomposition, so that the skin capillaries dilate and congestion, erythema, papules, allergies.
2. Insects. Many office buildings are now installed with central air conditioning, long-term ventilation without opening windows, the climate has turned warm, air conditioning breeding some microorganisms such as mites, floating in the air, some people inhaled will also cause allergies. As the weather warms up, some small insects such as whiteflies and midges also become active. These small insects burrow into the human body to bite the human skin, including their secretions on the human body, will induce papular urticaria.
3. Pollen. Spring is the period when most pollen is scattered. Some people have pollen allergy as soon as they come into contact with flowers. In mild cases, symptoms such as itchy eyes, nasal congestion, sneezing, runny nose and tears can occur, and in severe cases, bronchial asthma, allergic dermatitis, laryngeal edema, urticaria, neurovascular edema and other allergic conditions can be induced.
4. Food. In addition to the above-mentioned contact allergies to pollen and ultraviolet light, many people are allergic to certain foods in their daily lives, for example, some are allergic to allogeneic proteins in eggs, fish and shrimp, some are allergic to foods containing histamine such as shrimp and eels, some are allergic to foods containing porphyrin-like sun-sensitive substances such as mud snail, ashwagandha, rape and safflower, and some are allergic to proteases in lychee and pineapple. There are many foods that can easily cause allergies, and the symptoms caused by various food allergies vary and the clinical manifestations are intricate. Some people may even develop itchy skin, rash patches or fever, dizziness, nausea and vomiting immediately after eating allergic foods, which can trigger bronchial asthma and lead to breathing difficulties. Some people may also experience drunkenness or gastroenteritis symptoms such as abdominal pain and diarrhea. Others will develop sun allergic dermatitis with fever and headache after eating food with sun sensitive substances and then being exposed to sunlight. Some people continuously eat a large number of fresh litchi will appear dizziness, pale, cold sweat, palpitations, limb weakness and other allergic symptoms. Therefore, when eating discomfort symptoms, do not easily judge themselves food poisoning and so on, because it is likely to be a food allergy performance, and food allergies are said to cause varying degrees of heart damage, especially need to pay attention.
(B) Symptoms of allergic dermatitis

3, insect bite dermatitis clinical damage to the papule, the wind mass or petechiae as the most common, but also appear papule herpes
or blisters. The central part of the damage is often seen with prickly sucking points, scattered or in groups of several. Scratching often causes secondary infection or local lymph node enlargement. The lesions are mostly found on exposed areas. However, those caused by fleas and bedbugs are mostly in the covered area, and they feel itchy, burning or painful.

(D) How to prevent atopic dermatitis?
Spring has arrived, especially those who have a history of spring dermatitis should strengthen self-protection, so here is a reminder that people should pay attention to the following points.

Avoid eating saltwater fish, shrimp, crab and other foods that can easily cause allergies. Try to eat less or not to eat photosensitive foods that can easily trigger spring dermatitis, such as mud snail, capers, rape, spinach, lettuce, marjoram, buckwheat and figs.
2, plain for allergic people, the first use of a cosmetic product should be very careful, prior to the skin patch test should be done, such as no reaction, before use, otherwise not to use. Can not change cosmetics frequently, containing too much fragrance and too acidic and alkaline skin care products can not be used. High-grade cosmetics contain complex chemical ingredients and fragrances, which have more chances of causing allergies. When selecting and using skin care products, avoid using products that are irritating, such as those containing high concentrations of fruit acids, fragrances, preservatives, etc. Do not think that natural products will not cause sensitivity.
3, sensitive skin, cleansing, toning and moisturizing is the basic procedure, which can be toned depending on individual needs, but to choose something soothing non-alcoholic, as for scrubs, masks, one to two weeks to do once has been enough, and be careful to choose, such as whitening, anti-wrinkle, unless really need, it is best to wait for the sensitive phenomenon to improve before using. Remember to prevent and improve sensitive skin to have great patience, do not just apply products, to let the skin have the opportunity to “recuperate”, this is the most important!
4, enjoy the warm spring light at the same time, do not take it lightly, excessive UV exposure may cause skin burns at any time, red spots, blackening, peeling and other terrible allergy symptoms. Increase outdoor activities, first receive small doses of ultraviolet radiation, gradually increase the amount of light to gradually improve the body’s ability to tolerate light exposure, and beware of sudden and prolonged strong sun exposure. Try to avoid going out between 10:00 and 14:00. If you are traveling, it is best to wear a broad-brimmed protective hat or use a sunshade, and wear light-colored long-sleeved clothing. Also after rubbing on the basic maintenance products, make sure to apply sunscreen products again. However, the composition of certain sunscreens is also one of the factors of allergy. You should choose some physical sunscreens with simple ingredients, and try to avoid applying them directly on the skin surface, so that the stimulation of the skin is relatively less.
5. Spring pollen can be inhaled through the respiratory tract, and the flying willow flakes can easily cause allergic reactions when they come into contact with the skin. Allergy-prone people should go to parks and other places with more pollen and willow in the spring, and wear a good mask whenever they go out, and close doors and windows at home to prevent pollen and willow from entering the house with the wind, so that they can do their daily protection.
6, thoroughly clean indoor hygiene. The air conditioner, indoor corners should be thoroughly cleaned, especially if the family has pets, and sprayed with insecticide to remove microorganisms that may breed. Longer placed clothing do not take out on wear, it is best to get the sun for exposure, to drive away the possible existence of insect mites.
7, spring cold and warm air, the weather is hot and cold, may lead to immune disorders. To strengthen exercise, moderate exercise can activate immune cells and enhance immunity. Stress can affect the body’s hormone secretion, so that the immune system becomes poor, stimulating all kinds of allergic reactions. So even if life is busy and tired, do not forget to get enough sleep.
