The change of season is a high-risk period for various diseases. How can we prevent them? Let's take a look at the four common allergic diseases together with the editor!
Four common allergic diseases during the change of season
1. Allergic rhinitis
During the change of season, some people may have continuous clear nasal discharge, unbearable nasal itching, and frequent sneezing. These are typical symptoms of seasonal allergic rhinitis.
Allergic rhinitis is caused by flowers, grass, trees, etc. It has obvious seasonality and mostly occurs in spring and autumn, with autumn being the most common.
2. Allergic asthma
The allergens for allergic asthma mainly include pollen, dust mites, pathogens, climate, etc.
In autumn, the temperature is unstable, and there is a large difference between day and night. Asthma patients are often sensitive to the cold and hot stimulation of the air, which can trigger asthma attacks.
3. Allergic conjunctivitis
Allergic conjunctivitis is caused by pollen from plants dispersed in the air. The main symptoms include itchy eyes, irritation, photophobia, and tearing.
After being infected, the conjunctiva of both eyes becomes congested, there is increased secretion, and sometimes mild keratitis occurs.
4. Allergic dermatitis
Allergic dermatitis usually manifests as large patches of red papules on the body and face, accompanied by itching of the skin, and even itching of the scalp.
Patients with skin allergies should avoid excessive cleansing of the skin.
Prevention of the four common diseases
1. Allergic rhinitis
To prevent allergic rhinitis, first try to minimize outdoor activities. For those who are allergic due to the cool weather, they should maintain the humidity of the indoor air and avoid drying out the nose.
2. Allergic asthma
The surrounding environment of allergic asthma patients should be cleaned regularly to reduce dust in the air. Patients can go to a reputable hospital to test their own allergens and avoid them.
3. Allergic conjunctivitis
People who usually wear contact lenses or circle lenses should suspend their use. When traveling, wearing glasses or sunglasses can reduce exposure to allergens.
4. Allergic dermatitis
The sebum film and stratum corneum on the surface of the skin are the first line of defense for protecting the skin. Excessive cleansing destroys this barrier function, making it intolerant to various external stimuli such as temperature, causing allergic reactions.
