Entering spring, some people are prone to sneezing, runny nose, itchy eyes, coughing, and chest tightness. What is the cause and how should we respond? In most cases, it may be caused by allergies, especially pollen allergies, "said Ma Yanliang, chief physician of Peking University People's Hospital. In spring, wind pollinated flowers such as pine trees and poplar trees can cause allergic conjunctivitis, allergic rhinitis, and allergic asthma. Ma Yanliang reminds pollen allergy patients that clinical practice believes that early prevention is more effective than treating symptoms after they appear. "For example, allergic rhinitis patients can use nasal spray hormones such as budesonide and fluticasone 2-4 weeks before the spring pollen season to effectively alleviate hypersensitivity symptoms. She emphasized that during the pollen season, it is important to avoid contact with pollen allergens as much as possible and pay attention to the pollen concentration monitoring information released by the meteorological department. Once the pollen concentration increases, it is advisable to avoid areas with relatively high pollen concentrations. At home, try to close doors and windows as much as possible, use efficient air filters, and ensure that the indoor pollen concentration is relatively low. Once symptoms appear, seek medical attention promptly, especially for asthma patients who must carry inhalants containing emergency drugs such as salbutamol or formoterol with them. After the rainy season, humidity increases, which can easily lead to symptoms such as decreased appetite. Wang Hongbing, chief physician of Beijing Traditional Chinese Medicine Hospital, pointed out that during this period, the focus of health care was on strengthening the spleen and dispelling dampness, especially in southern regions. In terms of diet, we should follow the principle of "more sweet and less sour", eat less sour foods such as hawthorn and plum, and eat more sweet and sweet foods such as jujube and yam. At the same time, eat less raw, cold, greasy, high sugar and other foods that can easily increase moisture. He reminded that removing dampness is not suitable for everyone, because different people have different constitutions, and dampness is also divided into different syndrome types - "people with yin deficiency constitution and blood deficiency constitution who blindly remove dampness may further damage yin or consume qi and blood, so they should use dampness removal methods with caution. Spring is still a high incidence period for digestive diseases, especially symptoms such as diarrhea and vomiting are more common. Regarding this, Li Jingnan, chief physician of Peking Union Medical College Hospital, reminds us to start with daily hygiene habits: wash hands carefully before and after meals, thoroughly cook food, and clean raw fruits and vegetables. Food stored in the refrigerator should be heated before consumption, and overnight food should be avoided. At the same time, parents should cultivate good hand hygiene habits in their children to avoid cross infection. When mild symptoms such as nausea, vomiting, and diarrhea occur, Li Jingnan suggests drinking plenty of water, having a light diet, and taking relevant medications if necessary to control the symptoms. But if the symptoms persist or worsen, especially with fever, abdominal pain, etc., it is necessary to seek medical attention promptly. Recently, there have been media reports that some countries and regions still have high levels of influenza virus outbreaks. Regarding this, Peng Zhibin, a researcher at the Chinese Center for Disease Control and Prevention, stated that although acute respiratory infectious diseases in China continue to decline, self-protection measures still need to be taken. In densely populated places such as schools, it is recommended to strengthen environmental cleaning and ventilation to promote indoor air circulation. At the same time, health monitoring should be strengthened, and students and faculty should be encouraged to attend classes or work without illness. In terms of health care, Wang Hongbing reminds that in spring, attention should be paid to emotional regulation: maintain emotional balance in daily life and rest, sleep at night and wake up early, and add some green plants in moderation to help soothe liver qi; Increase exercise time and choose gentle aerobic exercises such as Ba Duan Jin, which are beneficial for blood and qi circulation; Eating more green foods can help relieve diarrhea, and it is also recommended to pair roses, jasmine, and chrysanthemums in moderation with tea to regulate emotions and maintain a positive mindset.
