During the seasonal change, be careful of "weather allergies"!
As autumn enters, the temperature difference between day and night continues to increase, and the atmospheric humidity also drops significantly. The autumn wind is blowing and the weather is getting cooler day by day. During this season, many people are prone to allergic symptoms.
Allergies are divided into many types. There are hundreds of allergens such as pollen, dust, chemicals, ultraviolet rays, etc. One type that is more likely to appear during the seasonal change is called meteorological allergy, which refers to the human body’s response to the weather. Various symptoms caused by excessive sensitivity to environmental changes belong to the category of medical meteorology. The root cause of weather allergies is the body's poor adaptability to weather changes. The symptoms of weather allergy vary from person to person, and may include inattention, memory loss, drowsiness, depression and anxiety, headache and dizziness, nausea, insomnia, sweating, rapid heartbeat, elevated blood pressure, etc.
Research shows that in the process of slow and cyclical changes in climate, meteorological allergies in the human body are caused by changes in temperature, humidity, air pressure and other factors (mainly seasonal changes), which cause the oxygen uptake of human cells. caused by changes in quantity.
Domestic experts have made a more detailed analysis of meteorological allergies caused by non-periodic changes in meteorological conditions. Generally speaking, when the weather changes, the stimulating effects of cold, warm, dry, wet, wind, frost, rain, snow and other meteorological factors are reacted to the hypothalamus through human skin. The hypothalamus in turn controls the pituitary gland to secrete corresponding hormones to regulate endocrine functions to maintain the body's balance after weather changes, that is, the stability of the human body's internal environment. However, everyone has different adaptability to climate. When the human body is temporarily unable to adapt to weather changes and the human body's adaptability decreases, symptoms will appear in breathing, blood circulation, metabolism and other body functions, and "weather allergy" will occur.
Autumn is a season when meteorological conditions change significantly. On the one hand, compared with summer, the temperature and humidity in autumn decrease, the air pressure increases, and the oxygen uptake of human cells also changes. For some people, symptoms of weather allergies such as depression, insomnia, and headaches are The physiological response of the body to adapt to climate change; on the other hand, autumn is also a season when the weather system is more active. Cold and warm air often invade alternately, and meteorological elements change more violently and frequently, which is most likely to cause more serious meteorological allergies, so special attention should be paid to prevention .
In addition, pollen allergies, which are relatively common in life, also have obvious seasonality. Most areas in my country have two pollen periods in a year, one in spring from March to May, and the other in summer and autumn from June to September. Pollen in spring is mainly from trees, while pollen in summer and autumn is mainly from grass and trees, such as chrysanthemums, lilies, osmanthus, roses, begonias, etc. Generally, there are more pollen allergy patients in summer and autumn than in spring, and the symptoms are more severe.
