Some time ago just into the volcano, around the partners have said “hot to faint”. While it’s nice to seek refreshment in the summer heat, it’s important to pay attention to health issues, especially for people with chronic diseases. So what do diabetics need to pay extra attention to in the summer? 1. Do not overdo it. Common complications of type 2 diabetes include high blood pressure and heart damage, and these complications are more likely to occur in the hot summer months. While advocating moderate exercise for people with diabetes, summer exercise must be moderate. There are two reasons for this: first, excessive exercise in the summer is more likely to increase the burden on the heart, and second, many diabetic patients will have nerve damage, which will affect the sweat glands to secrete sweat, without the support of the glands that help the body to naturally cool down, it is easy to lead to heat exhaustion and heat stroke, so you can choose to exercise in the early morning and late afternoon in the summer. 2, do not dehydration Diabetic patients themselves will be more than normal urine, in the summer without attention to replenish water from time to time, it is easy to cause dehydration. After dehydration, the body burden is further increased, which will lead to a further increase in blood sugar, thus forming a vicious circle. If the urine is dark yellow, or if you feel sluggish or dizzy, it may indicate that you are dehydrated. But be careful, it is best not to rely on iced tea, sugary soda, alcohol and other beverages to hydrate, these drinks will give you the illusion of “having drunk enough” because you will no longer feel thirsty, but the body may actually still be in a state of dehydration. So hydration is still appropriate with pure water. 3, sweating Diabetic patients may not easily feel hot, and can not be as effective as healthy people can excrete sweat, so often ignore the health threats brought about by high temperatures. In addition, summer humidity is also high, more likely to cause damage to the body. There is a concept called “heat index”, which refers to the fact that when the relative humidity increases in high temperatures, the real temperature felt by the body exceeds the actual temperature, and studies have shown that the temperature felt on the body surface may be 15° higher than the actual temperature. Therefore, diabetic patients must not feel that they are not hot to stay outdoors for a long time, and must prevent overheating, heat stroke and dehydration in summer. 4. Hypoglycemia A common early sign of hypoglycemia is sweating, which may be confused with sweating after the heat in summer. Therefore, diabetic patients should eat reasonably, take medication or insulin injections on time, and also monitor their blood glucose levels more often to never ignore the early symptoms of hypoglycemia. 5. Sunburn You definitely know that too much sun will make you darker, but you may not know that sun exposure may also raise your blood sugar level. Exposure to the sun is inherently a stimulus to the body, just like getting a cold or suffering other trauma, the body is in a state of stress, which can easily lead to an increase in blood sugar. Therefore, for diabetic patients, pay more attention to the summer sun protection. 6, avoid barefoot Summer is too hot, barefoot opportunities, but for diabetic patients it is best not to do so. Diabetic patients are often combined with nerve endings damage, will lead to limb (especially the foot) of the sensory dullness, foot injuries may not feel anything themselves. Combined with a reduced immunity, even small wounds or injuries may lead to serious infections or ulcers. 7, insulin injections also have a study High temperature will make the blood vessels dilate, insulin absorption accelerated, not only the maintenance time of the drug effect will be discounted, but also aggravate the risk of letting hypoglycemia. Therefore, when injecting insulin in summer, it is best to choose the injection site to avoid sweating and sun exposure. In addition, do not inject insulin immediately after outdoor activities, it is best to cool down indoors for 15~20 minutes before injection. Things such as glucose test strips, glucose meters and insulin should also be kept away from high temperatures.
