Copy allergies in summer, look at experts to support

The most common causes of skin allergies in summer are sunlight and mosquito bites.

Summer ultraviolet rays are strong and long time. After sun exposure, allergies such as erythema and itching are prone to appear on the exposure site, especially in women or lighter skin colors.

In the early summer, the incidence of light allergies is higher. Before the early summer, the skin is rarely irradiated with ultraviolet rays. As soon as it enters the summer, the ultraviolet rays have suddenly strengthened, and the skin cannot be adapted in a short time. In addition, people prefer outdoor activities in early summer, extending the time of ultraviolet exposure to a certain extent, which is also the main factor that causes sunlight allergies.

On the contrary, in the midsummer, after the ultraviolet rays in the early summer, the skin has a certain tolerance to ultraviolet rays. At the same time, due to the hot weather, people's outdoor activities have decreased or increased sun protection measures, and the incidence of sun allergies has decreased.

Preventing sunlight allergies, Gao Tao suggested:

1. To go out in summer, we must take sunscreen measures, such as playing with a sun umbrella, wearing a sun hat or applying sunscreen.

2. Do not "greedy" in early summer, gradually extend the time of outdoor activities or ultraviolet exposure, and establish the skin's tolerance to ultraviolet rays.

3. Few photovoltaic foods (such as gray vegetables, spinach, amaranth, amaranth, fennel, radish, purslane, lettuce) or photosensitive drugs (such as tetracycline antibiotics, ninosone antibiotics, pheaside diuretic drugs, non -non -diuretic drugs, non -non -diuretic drugs, non Anti -inflammatory drugs, oral contraceptives, etc.).

4. Dermatology is required for sunlight allergies. Specialists guidance and treatment, and do not abuse drugs on their own.

Summer temperature and humidity are suitable for mosquito breeding, especially mites and fleas. At the same time, people like to wear short sleeves, shorts, skirts and sandals. Some of the skin is exposed and provided conditions for mosquito bites. "After some allergic people are bitten by mosquitoes, there will be obvious red pimples to the size of broad bean -sized red pimples. When the allergic reaction will be severe, blisters will occur. Itching is unbearable.

Prevent mosquito bite allergies, Gao Tao suggested:

1. Try to wear trousers and socks as much as possible in summer to protect the skin. It really needs to wear shorts, skirts and sandals to spray mosquito repellent water.

2. Less contact with dust or humidity, these places contain a large amount of mites and fleas.

3. The clothes that have not been worn for a long time should be cleaned or wear after the sun.

4. Animals are easy to breed fleas. Pets at home need to be treated with pet deworming.

Prevention methods are quickly collected, stay away from allergies and enjoy healthy summer

Gao Tao introduced that finding and avoiding allergens is the best way to prevent skin allergies, especially for people who are allergic and people who are currently allergic. Possible causes of allergies can be speculated according to the shape and distribution of rash when allergic. There are mainly the following methods for finding allergens: 1. People who have limited skin allergies are often related to contact with exogenous allergens. They need to pay close attention to whether the skin in the allergies is exposed to metal, chemicals, plastic, cosmetics, and cosmetics, and cosmetics, and cosmetics, and Sunlight is easy to cause sensitive objects.

2. People who appear allergic to skin allergies are often related to food or drugs that are easy to cause allergies. It should be considered whether it is related to eating allergens such as seafood, milk, nuts, and allergens.

3. For allergens that have not been determined, you can make a allergic diary and record all suspicious allergens. After a period of time, count the frequency of allergens that appear in the diary.

4. You can go to the hospital for allergen examination or spotting test to further find allergens.

Finding and avoiding contact with allergen can effectively prevent skin allergies through the above methods. In addition, strengthening skin moisturizing and avoiding scaling and scratching can also prevent skin allergies to a certain extent.
