Experts reminded that Qingming period is vulnerable to emotional fluctuations, diet, weather, cardiovascular and cerebrovascular diseases, gastrointestinal discomfort, allergies and other "festival diseases", Qingming health should not be quiet. Statistics show that during the Qingming Dynasty every year, there are always some people who have physical problems. Experts reminded that Qingming period is vulnerable to emotional fluctuations, diet, weather, cardiovascular and cerebrovascular diseases, gastrointestinal discomfort, allergies and other "festival diseases", Qingming health should not be quiet. Attention should be paid to keeping warm and adjusting mood to prevent the recurrence of cardiovascular and cerebrovascular diseases. Experts warn that the prevention of cardiovascular and cerebrovascular diseases is much more meaningful than the most effective treatment. Because the temperature difference between morning and evening is large during the Qingming Dynasty, the cold and hot weather has the greatest impact on people with poor resistance. These people are most vulnerable to wind and cold, causing physical discomfort or aggravating the original condition. Experts said: "At the turn of the season, stroke, cerebral hemorrhage and other nervous system diseases are most likely to be caused. Running around tired, neglecting warmth, emotional fluctuations are often likely to aggravate the condition." Although most people know that people with poor intestines and stomach are not suitable for cold and indigestible food, many people still do not "hold on" to some traditional diet, which is related to greedy mouth. "In fact, not only during the Qingming Dynasty, almost every holiday, there are many patients with digestive system diseases caused by improper diet, and even some people know it is not appropriate to eat, but they still take chances." Expert introduction. It is understood that Qingming dumplings are mostly mixed with green juice and glutinous rice flour from Aicao, and then packed with stuffing. This kind of food contains starch and fat. For people with weak spleen and stomach and cold constitution, excessive consumption will increase the burden of intestine and stomach, and easily cause indigestion. Infectious diarrhea is also a predisposing disease around the Qingming Dynasty. "Because of the intake of unclean food and water, coupled with some people's unhealthy eating habits, make the disease from the mouth. Its clinical manifestation is diarrhea, accompanied by abdominal pain, fever, nausea, vomiting and other symptoms. Experts suggest that during the three-day short and long vacation period, especially the citizens who intend to travel, they should pay attention to food hygiene and not greedily eat roadside snacks. Men and women, old and young, should be active, clear and healthy, not quiet for three days. Some people choose to go out for a long vacation, while others choose to rest and adjust. "Especially the number of people who still fall asleep on the three poles of the day is not small. After the Qingming Dynasty, many young people came to report headaches, which made it difficult for them to get into work and even affected their sleep." Experts warn that this season is best to be able to go out for activities. Not only young people should refuse to become "homemakers", but the elderly should also go out more and relax, because in the Qing and Ming Dynasties, the middle-aged and old people will be more or less affected by the affection of the family atmosphere, and have the symptoms of depression. If there is no optimistic attitude to adjust, in the long run, it will hurt the liver and do harm to health. Therefore, health preservation in the Qingming Dynasty should be "moving" rather than "quiet". At this time, all things in nature are in a state of growth. People should also maintain a positive and optimistic attitude and go out more activities, such as traveling in the green, exercising and so on, can help maintain an optimistic attitude. Wearing masks and sunglasses to prevent allergies is the season of flowers, trees, leaves and flowers. The beautiful scenery often makes tourists forget to return, but Qingming is also a period of high incidence of pollen allergies. Peach blossom, willow and other pollen, flying floss is very easy to flutter with the wind, causing allergic people to produce nasal congestion, sneezing, runny tears, nasal itching and even systemic symptoms. Experts warn that tomb sweeping in the field during the Qingming Dynasty should also prevent dry lips and ultraviolet radiation. People with allergic constitution should wear masks and sunglasses as far as possible when visiting tombs in the field. In windy weather, it is better to walk in the direction of trees and flowers, and take medicines to prevent allergies when necessary.
