When the weather turns cold, it should be the time to arrange the long clothes and long pants, but a group of people insist on wearing single clothes, even if they are shivering in the cold wind, in order to avoid the bloated body Also “packed lightly”. There are even many beauty-loving ladies who don’t forget to wear short skirts and stockings to show their youth and vitality even in the sub-zero winter.
However, there are some rumors on the Internet, saying that “low temperature will lead to fat accumulation, the less you wear, the easier it is to gain weight”, and even say “the more you expose your legs in cold weather, the more likely your legs will become fat. The longer the meat, the thicker it is.” This can frighten the majority of fashion people who “want style but not temperature”!
Here, scientific rumors first tell everyone the conclusion: Don’t panic, this kind of argument is a “take it for granted” wrong argument.

In low temperatures
Fat burns faster
First of all, a low temperature environment will stimulate the body’s metabolic rate to increase, including fat metabolism. In order to resist the loss of skin temperature, the body will accelerate the metabolic rate and increase the energy supply. The main source is to burn sugar and release more energy.
Of course, prolonged exposure to cold and adequate energy supply does promote fat synthesis. However, this does not mean that the decomposition rate will decrease. When the body does a lot of exercise or needs a lot of fat, and the carbohydrate decomposition and energy supply cannot meet the demand, the fat will also be decomposed for energy supply, which is called “fat mobilization”. . Therefore, fat metabolism may not necessarily slow down in the cold state of winter.

Where does fat selection end up
It’s not about heat or cold, it’s about exercise
Secondly, fat itself is not as intelligent as we think, and it will not go wherever it is cold. The distribution of fat in the body can be found regularly. Generally speaking, the place where fat is most likely to be deposited is mostly the place with the least amount of activity. For example, the belly of men is most likely to develop a “beer belly”, while the buttocks and chest of women are fat deposits. most.
Of course, there is another place where fat deposits are more hidden, and that is visceral fat, such as liver and mesentery, where there is more fat. If according to the rumor that “fat is very smart, where does it go cold”, is it only our big belly that is afraid of cold? Don’t forget, it’s often the most tightly wrapped part. Besides, the parts of the body that are most afraid of cold are actually the joints, but whose knees have you ever seen “fat”?

The root of fat and thin
is the supply and consumption of energy
The human body does not completely adjust the thickness of subcutaneous fat in response to the external environment. Although people living in the cold zone are generally fatter than those living in the tropics, this is indeed the result of the body’s self-protection awareness in the process of natural evolution. However, the fundamental factor determining the thickness of subcutaneous fat is the ratio of energy supply and consumption, that is, when the intake is greater than the consumption, the fat will increase, and vice versa.
Of course, ambient temperature does affect energy metabolism in the body, but it is only one of many factors. That is to say, if we eat and eat without exercising in winter, no matter how much you wear, you will gain weight. However, if you eat a balanced diet and exercise properly, your body will not be affected by the temperature. What’s more, no one is exposed to the cold for long periods of time, especially these days, when short periods of outdoor cold temperatures don’t have a substantial effect on body fat distribution.

Good manners
Don’t sacrifice your health
Although cold clothing doesn’t make us grow fat legs, it can also affect our health. Some people say that young people have a lot of firepower and are strong enough to withstand severe cold. In fact, it only depends on a high metabolic rate. This high metabolic rate state also brings health risks. Moreover, the cold will still stimulate the body, especially the bones and joints, causing discomfort. If you do not pay attention to keeping your legs and feet warm, it will also increase the risk of urinary system diseases.
Some young people wear thin clothes and use warmers on their knees and belly to keep them warm, hoping to reduce the irritation from the cold. Here to remind everyone, be sure to pay attention to how to use it, and don’t rely too much on it. High temperature contact or prolonged low temperature contact will have an impact on the skin, and gradually develop into scalding of the deep layers of the dermis and subcutaneous tissues, and will also make the skin dry and itchy, leading to skin allergies and dermatitis. Not worth the loss.

The world is beautiful because of its rich diversity. Spring has hundreds of flowers and autumn has the moon, summer has cool breeze and winter has snow. In the warm June and July, we wore elegant dresses, and in the cold winter, we experienced the care and wrapping of warm cotton-padded clothes. It is not a blessing in life. Fashion and taste do not need to stick to their teeth. It is very important to keep warm in winter, and dressing that fits the season can also become a beautiful scenery in the snowy winter.
