The cold winter months are here and many diseases strike during this time of low temperatures. According to statistics, more than 70% of all winter deaths peak within three days of the impact of strong cold air. People with diabetes need to protect themselves in winter. The cold will stimulate sympathetic excitation and increase the secretion of catecholamines in the body, making it easy for blood sugar to rise and platelets to gather and form blood clots, which can contribute to blood sugar fluctuations and blood pressure increases. Diabetic patients have low resistance, and the cold is more likely to cause patients to catch a cold, thus inducing lung infection. In addition, the cold also causes peripheral vascular constriction, increasing the risk of diabetic foot. It is especially important to prevent infections. In cold winters, people tend to close their doors and windows tightly, which causes no air convection and makes it difficult to discharge the smoke, dust and carbon dioxide exhaled by the human body, making the indoor air dirty and especially prone to respiratory diseases. The correct approach is to set up air windows in the room or regularly open windows for ventilation. When ventilating, diabetic patients pay attention to avoid the body from cold wind to avoid catching cold. In terms of diet, although the secretion of digestive juices increases in winter and people have a better appetite, they should also control their diet to be light, varied and rich in a variety of nutrients. The decrease of temperature in winter will cause the respiratory mucosa resistance to decline, skin elasticity, skin infections, urinary tract infections, etc. are the most common complications of diabetes, especially patients with chronic pharyngitis, sinusitis, bronchitis, it is easy to occur lung infections, and even become the main cause of life-threatening. Therefore, it is especially important for diabetics to prevent infections. Three reminders in the winter Increase the frequency of blood glucose monitoring: Cold causes an increase in glucagon hormones such as adrenaline, while insulin secretion is reduced in diabetic patients, so blood glucose is prone to fluctuations, so the frequency of blood glucose monitoring should be increased, and special attention should be paid to blood glucose fluctuations at night Avoid diabetic foot: Cold can cause peripheral peripheral vasoconstriction, which affects blood supply to the lower limbs and feet and aggravates or induces the occurrence of diabetic foot, so it is necessary to keep warm in time. Winter sweat less, dry skin, feet are easy to crack, so check the feet every day, every night with about 40 degrees Celsius hot water soak feet for 15 minutes, do 10 minutes of foot massage helps to prevent cold and improve local blood circulation, after washing feet can rub some skin cream to keep the skin lubricated. Wear loose and warm shoes to avoid frostbite. Avoid tearing the skin of your feet and rubbing your toes to stop itching, to prevent skin breakage that could lead to septic bacterial infection. Prevention of depressed mood: 50% of diabetic patients suffer from varying degrees of depression, while the winter cold, go out less activities, friends rarely meet and chat, prone to mood swings. Emotional excitement can cause sympathetic excitement, which can prompt the release of glycogen in the liver into the bloodstream, and increase blood sugar levels, leading to aggravation of the disease or reduce the effectiveness of treatment. Therefore, diabetic patients should learn to control their emotions, avoid negative emotional influences and maintain emotional stability.
