Why is it difficult to control blood sugar after the weather is cold?

In different seasons, the increase of blood sugar will be affected to some extent. Generally speaking, the increase of blood sugar will be more obvious in winter than in summer.

It's freezing in winter, and when the weather is very cold, our human body will increase the sympathetic nerve tension in the body while sensing cold air, which will lead to an increase in blood sugar. Moreover, some patients with hypertension and cardiovascular and cerebrovascular diseases should also take care of themselves in winter, because the probability of cerebral hemorrhage and myocardial infarction in winter is much higher than that in summer.

If I ask you a question, would you like to go out in summer or in winter? I believe many people are willing to go out in summer. Although it is very hot in summer, many people will take a walk outside after dinner and blow a cool breeze. Therefore, the human body consumes a lot in summer, and blood sugar is easier to lower. Some people with hypoglycemia even have hypoglycemia. In winter, people will also become lazy, and few people will insist on exercising outside. When human consumption slows down, blood sugar will rise slowly.

I believe many people eat more food in winter than in summer. It is very hot in summer, and many people have no appetite. Some people can't get much calories in a dog's day. Eat less staple food, and blood sugar will naturally not rise. But winter is different. It is cold in winter, and the human body will take the initiative to eat more food for the protection of its own body functions. Sometimes you have to eat several bowls. Eating so much food will naturally raise blood sugar.

Therefore, some patients with hyperglycemia should be strictly controlled in winter to prevent blood sugar from rising, and some friends with hypertension should also pay special attention.
