Allergic diseases have been listed by the World Health Organization as one of the three important diseases for the 21st century. Summer is also a period of high incidence of allergic diseases. Today, Xiaobian will take stock of the causes of summer allergy problems and ways to avoid allergies.

Air conditioners are always on

There are many pathogenic bacteria in the air-conditioning area, such as mites, dust, pollen and mold. Summer temperature and humidity are very favorable for mite growth and reproduction, so it is easy to cause summer mite allergy.

The mite body is very tiny, and it is difficult for humans to find it with the naked eye. The toxins released after it bites the human body can easily make people allergic to urticaria symptoms such as papules and erythema. If it is scratched by hand, it can also cause skin infections and purulence.

Jewelry allergy

In patients with contact dermatitis in the summer, many are caused by wearing metal necklaces, and others are caused by wearing bracelets, anklets, and earrings. The allergic symptoms of these people are manifested in the parts where the jewelry is in contact with the skin, and some people will have a systemic allergic reaction, first the skin is red and swollen, and then they start to have small pimples, blisters, and even itching all over the body.

food allergy

There are many kinds of food in summer, some of which are allergic factors, such as fish, shrimp, crab, etc. These foods are prone to cause skin redness, rash, itching, wheal and other symptoms. In addition, food additives such as condiments, colors, preservatives, etc. can also cause allergies.

UV allergy

After exposure to the sun, erythema and blisters appear on the exposed skin of the neck, arms, shoulders and back, and itching is unbearable. The erythema and edema subside after a few days, followed by desquamation, molting, and leaving temporary Pigmentation. This process is an acute damaging reaction of the skin under strong sunlight. Repeated sunburns will make the skin sensitive to light and produce a photosensitizing reaction.

Changes in temperature and humidity

Many white-collar workers sit and work in the office every day. The moisture of the skin is dried up by the air conditioner, which causes the skin's stratum corneum to be seriously dehydrated, the skin circulation is disordered, and there is redness or red blood on the face.

Antiperspirant allergy

Some people are worried about excessive sweating in summer, and the underarm clothes will be soaked in large pieces, which greatly affects the image, so they use deodorant antiperspirants. Its main function is to temporarily close the sweat gland duct as an astringent, transforming the sweat glands into small sweat glands, and the natural spices play a role in aroma masking and deodorization.

From a pharmaceutical point of view, the principle of antiperspirant is reasonable, but from a physiological point of view, forcibly antiperspirant can cause clogged pores and metabolic products can not be discharged normally. In addition, some people will also be allergic to certain substances in the deodorant bead, which can cause allergic dermatitis in severe cases. Once there is redness, swelling, itching, etc. in the smeared area, you should seek medical treatment in time to avoid expanding the condition.

Pay attention to details to avoid allergies

To deal with allergies, the most effective measure is to find out allergen-inducing factors and stay away from this substance. Second, pay attention to some details in life.
