Allergic constitution is generally due to genetic factors or bad habits in life, which leads to abnormal autoimmune mechanism and loss of normal immune tolerance function, so it is called allergic constitution for some people who are prone to allergic reactions.
Spring is the season of high incidence of allergies. Pollen, dust, dry air, changeable weather and enhanced ultraviolet radiation are the reasons for frequent allergies in spring. The peak time of pollen appearance is from 5 am to 10 am. People with allergies should try to avoid going out at this time. If they have to go out, it is recommended to take protective measures when they go out. Of course, masks are necessary for us.
When going out for an outing and meeting many plants, it is best to wear anti-allergic drugs and take them according to the doctor's advice to avoid sudden symptoms and physical discomfort. People with allergic history should pay attention before flowering. There are many anti-allergic drugs now, which not only have indirect effects, but also have preventive effects. Therefore, people with a history of allergies can start taking anti-allergic drugs one week in advance.
Allergic people should not stay outdoors for a long time, stay outdoors as little as possible during the day, wear masks when going out, and avoid places with high pollen index. Usually around noon, the pollen concentration is the highest. Try to wear that kind of high-density mask, because it can effectively prevent the harm of dust. I think we should judge whether we have symptoms of pollen allergy in time and pay attention to prevention at ordinary times. Try not to eat some irritating fishy food often, which is good for the stomach.
