The reasons why people are prone to allergies in autumn are revealed, and what to do

Summer will soon be gone, and we can feel the cool autumn weather now. However, many people are prone to skin allergies in autumn. Why is this?

1. The air conditioner is often turned on, which can cause mites

There are many pathogens accumulated in air conditioners, such as mites, dust, pollen and mold. Mites are very small and difficult to detect with the naked eye. The toxins released by them after biting the human body can easily cause allergies, and symptoms of urticaria such as papules and erythema will appear; if you scratch them with your hands, it will cause skin infection and suppuration.

2. Allergy to jewelry

Many patients who develop contact dermatitis in autumn are caused by wearing metal necklaces, while others are caused by wearing bracelets, anklets, and earrings. These people have allergic symptoms where the jewelry touches the skin, and some people may have systemic allergic reactions, first with redness and swelling of the skin, followed by small papules, blisters, and even itching all over the body.

3. Food allergies

There are many kinds of food in autumn, some of which are factors that induce allergies, such as fish, shrimp, crab, etc. These foods are prone to cause skin redness, rashes, itching, wheals, etc. In addition, food additives such as seasonings, pigments, preservatives, etc. can also cause allergies.

4. Ultraviolet light allergy

Although autumn is not as hot as summer, the sun is still scorching. After being exposed to the sun, red spots and blisters will appear on the exposed skin of the neck, face, arms, shoulders and back, which will itch like fire. After a few days, the red spots and edema will subside, followed by scaling and flaking, and temporary pigmentation. This process is an acute injury reaction of the skin under strong sunlight. Repeated sunburn will make the skin sensitive to light and produce photosensitivity reaction.

5. Temperature and humidity changes

Many white-collar workers sit in the office to work every day, and the moisture of the skin is sucked away by the air conditioner, causing serious lack of moisture in the skin's stratum corneum, disordered skin circulation, and facial redness or red bloodshot. The huge temperature difference between indoors and outdoors can also cause skin allergies.
