Winter is a cold climate, is a good season for all kinds of diseases. And cold winter is always frozen out of the disease, the following to understand the freeze out of the six kinds of disease, then how to do a good job in winter to prevent cold and keep warm? Winter is easy to be frozen out of five kinds of disease? 1, sudden heart attack The normal internal body temperature is generally 37 degrees Celsius, if it falls to 35 degrees, the symptoms of hypothermia began to appear. At first, people can stay awake and raise their body temperature through chills. However, when the body temperature drops to 33 degrees, the person may lose part of their memory. At a body temperature of 28 degrees, most people lose consciousness and choke as a result. Body temperature is lower than 21 degrees, the limbs of the blood vessels have contracted, blood reflux, blood pressure rises sharply, heart attack may therefore, from death is not far away. 2, joint rheumatism In winter, wear less, every time by the cold wind blowing legs will hurt, night pain in the bones, can not sleep. There are generally two reasons for this situation: one may be the previous legs and feet have suffered from wind, cold and dampness and other attacks, with the increase in age, the body’s immunity gradually low, a cold wind induced by. In addition, it may also be caused by a deficiency of kidney yang, yang deficiency body will be cold limbs and fear of cold. Cold is induced arthritis and rheumatism factor of a powerful external factors, can not be ignored, please pay attention. 3.Facial paralysis If you wear thin winter and long time outside in the cold wind, the face by cold stimulation caused by local nutrient nerve vasospasm, resulting in ischemia and edema of the nerve tissue and lead to facial paralysis. Prevention of facial paralysis mainly starts from reducing cold wind stimulation. Do not drive or sleep with the windows open for a long time to blow cold wind, and wear a good scarf and mask to wrap your face outdoors. If facial paralysis occurs, you should go to a specialized hospital in time to receive antiviral, hormone, neurotrophic drugs and other symptomatic treatment. 4.Frostbite frostbite Frostbite is common in winter, due to the cold climate caused by local skin recurrent erythema, swelling damage, blisters, ulcers can occur in severe cases, the course of the disease is slow, the climate warming self-cure, easy to relapse. Cold is the main reason for the onset of frostbite. The cause of its onset is frostbite patient’s skin in the encounter cold (0 ~ 10 ℃), damp or cold and warm rapid change, local small arterial contraction, long time arterial vascular paralysis and dilation, venous stasis, poor local blood circulation and the onset of the disease. In addition, the patient’s own skin moisture, terminal microvascular malformation, autonomic nervous dysfunction, malnutrition, endocrine disorders and other factors may also be involved in the onset. Lack of exercise, sweaty and moist hands and feet, tight shoes and socks and long-term outdoor work at low temperatures and other factors can lead to the occurrence of frostbite. 5, repeated colds The lowering of the body temperature will lead to the contraction of capillaries in the nasal mucosa, followed by a reduction in blood supply, the number of immune cells will also decline, the virus into the nasal cavity will have a greater probability of infected cells. Although cold temperatures are not the direct cause of colds, they can lower a person’s immunity and aggravate the condition of those who are already infected with the virus but have no visible symptoms. Colds due to freezing temperatures are often not easy to treat and tend to recur once cured. How to keep warm in winter? 1, dress to science does not have to be more In order to prevent the cold, we tend to add three layers of clothing, wrapped up tightly, turtleneck sweaters, small vests, thick cotton, in short, can be cold things are used, thinking that this can keep warm, in fact, wear more, the body’s own thermoregulation will decline, but easy to get a fever and a cold. At the same time, clothing is too tight, the human blood circulation will be hindered, but not conducive to warmth. 2, winter clothes to choose how to choose to choose light and warm down jacket or can withstand the cold wind of the leather jacket, you can wear a slightly loose inside the soft sweater, but do not let the neckline is too tight, otherwise it is easy to cause cerebral blood supply. Scarf mask precautions In addition, some people in order to block the wind, love to put the scarf around the mouth, or wear a mask, the nose and mouth are hidden. In fact, if the scarf around the mouth, when the person in the whistle, small wool fibers and bacteria will be inhaled into the lungs, causing respiratory tract infection. If you wear a mask all day long, the nasal cavity and the mucous membrane of the whole inhalation tract can not get exercise, the processing function of the cold air is artificially weakened, a little cold, but easy to catch a cold. Therefore, wear a scarf to expose the mouth and nose to keep the whistle open; if not air pollution is serious, try not to wear a mask.
