Several attacks of hazy weather not only make the weather difficult to get rid of the foggy entanglement, but also directly affect the air quality, which can easily trigger acute upper respiratory tract infections, acute bronchitis, bronchitis, pneumonia, asthma attacks and other diseases. Hazy weather persistently does not dissipate, will increase the burden on the circulatory system, may induce angina pectoris, myocardial infarction, etc.. In particular, the hazy weather reduces sunlight, the body does not produce enough vitamin D, the absorption of calcium is greatly reduced. Now many areas of the hazy weather phenomenon as a catastrophic weather warning forecast, anti-hazy weather healthy diet should include four aspects of dust removal, calcium supplementation, lung anti-virus, enhance immunity, etc., for diabetic patients to supplement calcium is particularly important. Calcium intake by the human body needs to be absorbed with the participation of vitamin D. Ultraviolet rays from the sun can make the human skin produce active vitamin D, thus promoting the absorption of calcium. Due to the lack of ultraviolet radiation, the body’s active vitamin D production is insufficient, making it easy for people to become mentally lazy, depressed and other “calcium deficient” phenomena. For children, the lack of vitamin D production in the body, the absorption of calcium is greatly reduced, which can cause serious infantile rickets, child growth slowdown. For diabetic patients, calcium deficiency also affects the treatment of the disease. Insulin can stimulate the formation of bone collagen to help bones retain calcium and rebuild, while the low level of insulin in the blood of diabetic patients or insufficient insulin action can easily cause disorders of sugar, fat, protein and mineral metabolism, thus affecting bone tissue metabolism and imbalance of calcium-regulating hormones, resulting in calcium deficiency in the body, so diabetic patients are more prone to osteoporosis than non-diabetic patients, and if fractures occur their Wound healing is also slower. The persistence of foggy weather will increase the burden on the circulatory system of the elderly and may induce angina pectoris and myocardial infarction. Many studies have shown that calcium can lower the concentration of cholesterol in the blood, thus playing a role in protecting the heart, and can also trigger coronary heart disease if there is a serious calcium deficiency for a long period of time. Therefore, proper calcium supplementation can prevent the occurrence of diabetic cardiovascular disease and greatly reduce the incidence of diabetic complications. You should drink more water during foggy weather, pay attention to a light diet, eat less stimulating food, and eat more milk, sea fish, black fungus, black sesame, seaweed, seaweed, hairy vegetables, tofu, lean meat, nuts, etc. These foods are rich in vitamin D, which is beneficial for calcium supplementation. Commonly used synthetic calcium salts include calcium carbonate, calcium phosphate, calcium citrate and calcium gluconate. Patients with osteoporosis can use vitamin D, bisphosphonates and calcitriol under the guidance of physicians. Bone must be in a weight-bearing state in order for calcium to be effectively absorbed into bone tissue. Therefore, maintaining a certain intensity and frequency of exercise can enhance the ability of bones to withstand load and muscle tension, which can effectively improve the effect of calcium supplementation and prevent osteoporosis. Although the hazy days are not suitable for outdoor exercise, diabetic patients can exercise at home through Tai Chi, indoor health exercises, indoor exercise machines, etc. Bad habits should be overcome. Smoking, drinking, sweet drinking coffee, etc., will not only lead to an increase in blood sugar, but also interfere with the absorption and utilization of calcium, which can easily trigger osteoporosis and should be quit.
