Spring is the season when asthma attacks easily. According to Chinese medicine, everything revives in spring, Yang Qi gradually rises and Yin Qi gradually disappears, asthma patients mostly have the physical characteristics of persistent phlegm in the lungs. This is the intrinsic reason why asthma is prone to occur in spring. The concentration of pollen particles in the air rises significantly in spring, and these pollen floating in the air can trigger or aggravate asthma. In addition, spring sand and dusty weather increase the concentration of respirable particles, which can also cause asthma attacks. There is no medical cure for asthma, but as long as we adhere to a scientific lifestyle and prevent and treat it properly, the chances of developing asthma will be greatly reduced. Scientific prevention and control of asthma attacks in spring should start from daily life and living. First, the living environment should be improved to eliminate triggering factors. Indoor cleaning to keep clean, often open the windows for ventilation, but in the case of pollen, fog and dusty weather, full of car exhaust factory pollution, etc., it is best not to open the windows. Do not smoke, burn incense, do not use mosquito spray, perfume, etc. to avoid stimulation caused by the aggravation of the disease. Do not use a variety of decorative materials containing a lot of chemicals, do not keep cats, dogs, rabbits, pigeons and other hairy pets, because animal fur in the parasitic bacteria, mold, mites, etc. may become the bane of asthma attacks. In spring, everything revives and various pests hidden in the living room start to move, mosquitoes, flies, dust lice, bedbugs cockroaches can be the culprit of asthma attacks, especially cockroaches, every part of its body, may be the allergen of asthma attacks. These pests can be eliminated by spraying insecticide, but when spraying insecticide, make sure to keep patients and children out of the living room, and after the insecticide has taken effect, ventilate thoroughly before inviting them home. Second, a healthy diet is an important safeguard to avoid asthma attacks. Avoid eating too much fatty, sweet, thick, salty, spicy and fishy food, high sugar, high salt and high fat diet, so as not to brew dampness and produce phlegm, which will trigger asthma attacks. To properly supplement vitamin-rich foods, vegetables such as radish, winter melon, loofah and pumpkin have the effect of lowering gas, resolving phlegm and clearing the lungs, so it is very beneficial to asthma patients to eat more in spring, in addition, fruits can eat more pears, bananas, grapefruit, Chinese medicine believes that pears have the effect of resolving phlegm and relieving cough, clearing the heart and moistening the lungs. Bananas are rich in A, B, C, E and other vitamins, and contain a chemical substance that can stimulate mucosal resistance and enhance mucosal protection. Grapefruit is rich in vitamins that can lower blood pressure and relieve the heart, expectorant and moisten the lungs, calm asthma and stop cough. Asthma patients should constantly summarize the foods that may induce their condition to worsen in their daily life so as to avoid eating these allergenic foods. Again, asthma patients should stay away from the stimulation of tobacco and alcohol. It has been found that the smoke in tobacco or the vapor of wine will stimulate the surface receptors of the trachea, and through the vagus nerve reflex, the smooth muscle of the trachea will spasm, which can induce an asthma attack. Asthma patients who drink strong alcohol can cause immediate attacks in eliminated patients, and patients who drink low levels of alcohol also experience a significant increase in respiratory resistance. Therefore, asthma patients must be fully aware of the dangers of tobacco and alcohol to their condition and stay away from tobacco to be able to reduce attacks.
