How to survive pollen allergy season?

Allergies can occur in people of any age

Is a minor allergy the sixth most common chronic disease in the world? Yes! The World Health Organization has long listed allergic diseases as one of the diseases that require key research and prevention in the 21st century.

Allergies can be divided into seasonal allergies and perennial allergies. Seasonal allergies often break out in a certain season, and pollen is the most common and important airborne allergen in the world.

There are two types of pollen transmission

Wind-borne pollen is the main allergen

Many people are confused

Why do I still get pollen allergies even if I stay away from flowers?

Expert introduction

Pollination in nature is mainly

There are two forms: wind-borne and insect-borne

The "culprit" of spring pollen allergies is often not the brightly colored ornamental flowers, but rather trees and weeds that do not look like they will bloom.

Insect-pollinated pollen → pollen from rapeseed, peach, and pear flowers is spread by insects such as butterflies and bees. It is characterized by brightly colored flowers with fragrance or other odors, large pollen particles, and small amounts of pollen. It is not easy to spread everywhere and usually does not cause allergies.

Wind-borne pollen → such as pollen from cypress, poplar, willow, birch, sycamore, etc., is characterized by small flower shape, high pollen content, light weight, and can be flown to far places by the wind. Wind-borne pollen is the main allergen.

Spring pollen allergy

Can cause a variety of adverse reactions

Spring pollen allergy

An allergic reaction disease

Cui Yong, deputy director of the China-Japan Friendship Hospital and director of the Dermatology Department, said that mild allergies may only cause itching and rashes, while severe allergies may cause laryngeal edema, shock and other symptoms, which may cause death if not treated in time. Allergies can occur in people of all ages, and people with allergic constitutions should be especially careful.

Some patients have

Eye symptoms usually include itchy eyes and tearing

Or conjunctival congestion

It may also cause photophobia in the eyes.

✍Precautions:

Wang Lianglu, executive deputy director of the Department of Allergy at Peking Union Medical College Hospital: There are indeed some targeted preventive measures now, such as wearing masks and goggles during the pollen season. Goggles must be sealed to cover the eyes completely.

Expert introduction

Allergic rhinitis

Common diseases caused by pollen

Nasal congestion, itchy nose, runny nose, sneezing, and itchy eyes are the main symptoms of allergic rhinitis. Compared with colds, allergic rhinitis generally does not cause sore throat, fever, or other systemic discomfort. It usually lasts for more than 2 weeks, and patients with allergic rhinitis often develop the disease at a fixed time every year. At present, there is no way to completely cure allergic rhinitis, but early intervention can alleviate the patient's symptoms.

✍Precautions:

Wang Lianglu, executive deputy director of the Department of Allergy at Peking Union Medical College Hospital: When you wake up in the morning, you can first do nasal irrigation, then use nasal spray hormone, and then use pollen barrier. This can prolong and enhance the effect of nasal spray hormone, which can play a good preventive as well as therapeutic role.

Pay attention to prevention and medication control

'Two-pronged approach'

Now is the pollen transmission season. Professor Zhang Jianzhong, director of the Department of Dermatology at Peking University People's Hospital, recommends that everyone pay attention to a "two-pronged approach" of prevention and drug control.

✍Prevention:

People with hay fever should go out less and keep windows closed;

Wear a mask when going out and avoid areas with high pollen concentrations;

After going out and coming home, remember to wash your face, especially your nose and eyes, and change clothes that are stained with pollen.

✍Medication:

People with hay fever can use sea salt water to clean their nasal cavity and use anti-allergic eye drops to control symptoms such as itchy eyes of allergic conjunctivitis;

Patients who develop cough or wheezing may need additional oral and/or inhaled medications to control symptoms.

Patients with severe symptoms and long duration should go to the hospital for desensitization treatment in time.
