Recently there has been serious haze weather in many parts of China, and Nanjing is no exception. The haze weather brings great hidden dangers to people’s health. Diabetic patients have poor immunity and should be more careful in dealing with it. In 2013, “haze” became the keyword of the year. By now, people are used to the word “haze”, as it has been occurring in recent years. So what exactly is “haze”? Fog is a non-toxic and harmless natural phenomenon, while the formation of haze is mainly the result of a large number of particles suspended in the air and the combined effect of meteorological conditions. Haze is mainly composed of sulfur dioxide, nitrogen oxides and respirable particulate matter, which combine with fog to make the sky instantly gloomy and gray. The abbreviation for particulate matter is PM, and Beijing monitors fine particulate matter (PM2.5), which are pollutant particles with an aerodynamic equivalent diameter less than or equal to 2.5 microns. The particles themselves are both a pollutant and a carrier of heavy metals, polycyclic aromatic hydrocarbons and other toxic substances. Haze is known as an invisible “health killer”, and its mixed harmful substances can cause direct harm to human health. Since diabetes patients have low resistance and poor immunity, and winter is a “difficult time” for diabetic patients to control blood sugar, it will be worse if they get sick at this time. In this reminder: hazy days travel, beware of respiratory diseases, sugar lovers should do the following: 1, travel to wear a mask. Although ordinary masks can not block all the harmful substances, but can block the air toxic and harmful, relatively large organic particles. Adding a filter layer inside the ordinary mask can play a better effect. However, the mask must be worn tightly, especially at the bridge of the nose, otherwise the particles will still enter the respiratory system through the gap at the bridge of the nose. 2.Change outdoor sports to indoor sports. Proper outdoor sports can enhance physical fitness and fresh air. However, if it is a hazy day, it is not suitable to carry out outdoor sports. Therefore, it is recommended that when the air quality is bad, sugar lovers can choose health exercises, tai chi and other indoor sports. 3, diet help to keep up. Vitamin C, E has an antioxidant effect, appropriate supplementation can help reduce air pollution caused by oxidation or peroxidation reaction to the body damage. Sugar lovers eat more vitamin C-rich vegetables, fruits, but also appropriate to eat some animal offal to supplement vitamin E, but must ensure a balanced diet. 4, maintain a good mental state. The mental burden of diabetic patients is usually heavy, plus the air gray cloud to a certain extent affect the mood. Diabetics themselves should be optimistic about the disease, establish a strong belief in overcoming the complications of diabetic disease, to prevent negative emotions. In addition, diabetic nephropathy patients in the hazy weather to pay more attention to their bodies, haze easy to make diabetic nephropathy patients infected. There are a lot of dust, sulfuric acid, nitric acid, and organic hydrocarbons in the haze that are harmful to health, and diabetic patients with poor resistance are very likely to have lung and airway infections that aggravate their condition. Therefore, in the face of disappointing air quality, diabetic patients also need to prevent infection, which is likely to aggravate the burden on the kidneys and worsen the condition of diabetic nephropathy. Try not to go out in hazy weather, and wear a mask when you go out. Diabetic nephropathy patients try to avoid crowded areas. Clean your face and skin immediately after returning, and most importantly, in your mouth and nasal cavity. The unsatisfactory foggy weather will not last long, and the fog will have to escape when spring blooms. But in these days, diabetics should pay good attention to the above hazards brought by the haze, take action, pay attention to it, and step up prevention in hazy weather.
