It is unscientific to lose weight with plastic wrap.

May cause a variety of skin diseases.

Plastic wrap can keep food delicious, but now some slim women have developed its new "function". They wrapped themselves in plastic wrap to lose weight before exercise, and even some stars introduced it to women as a "slimming secret". Huang Guangmin from the Institute of Sports Medicine of the State General Administration of Sport pointed out that this "folk prescription" for losing weight is unscientific, which not only can not fundamentally achieve the effect of losing weight, but may also cause various skin diseases.

The reporter found in some fitness centers that many women wrap their bodies with plastic wrap before fitness.

An "experienced person" who often goes to the gym said that you can wrap several layers on the part where you want to lose weight most until it is airtight, and then you can exercise hard in the gym or on the treadmill. In a fitness center, Miss Zhang, who often wraps the waist, abdomen, thighs and other parts that are easy to accumulate fat with plastic wrap before fitness, told reporters: "Sometimes I wrap it for an hour or two, and sometimes I wrap it for three or four hours." Asked about the feeling of being wrapped, she said that being wrapped in plastic wrap was really boring, hot and uncomfortable, but after exercise, she obviously sweated more than being wrapped.

Director Huang said: "It is unscientific to lose weight with plastic wrap, and you can't lose weight fundamentally. Because the limbs are wrapped with plastic wrap, it affects the heat dissipation of the body surface, increases the local temperature, increases perspiration, and then makes the water of local fat cells and other tissue cells temporarily penetrate outward, but this will not increase the consumption of fat. After drinking water and eating, these cells return to their original state. In this way, it will also increase the loss of electrolyte, which is easy to cause fatigue and is not good for the body. Wrapping the body with plastic wrap for a long time will make the skin unable to dissipate heat, make sweat accumulate locally, and easily cause skin diseases such as eczema and folliculitis. In addition, plastic wrap itself is a chemical substance, which is easy to cause skin allergies and other potential hazards to the body. "

"Wearing thick sportswear or corsets can only temporarily reduce weight. Once hydrated, the weight will recover. " Director Huang introduced that the best way to lose weight is to exercise a little for a long time, and at the same time pay attention to the requirements of a balanced diet. The general principle is that the exercise center rate is 120 times/minute, the exercise time lasts for more than 45 minutes, once every other day or every day, and attention should be paid to the diversification of exercise.

The body relaxes better after exercise.

The "cooling" after exercise can not be ignored, just like the "preheating" before exercise, so as to achieve the effect of exercise. This is a report on the American Daily Health website.

In real life, we often see some people leave without relaxing after strenuous exercise, which is incomplete and unscientific. According to the report, the human body needs to gradually return to a relatively quiet state after exercise, which is a relaxation means to relieve physical and mental tension during exercise.

"From a psychological point of view, relaxation after exercise needs to be carried out properly, and the first is mental relaxation. A good mood can promote people's behavior, and a negative mood may also make the original interesting things boring. " The report said.

In addition, from the physiological point of view, only when you are in a good mood can you relieve the physical tension formed during exercise in time, so that the respiratory system, cardiovascular system, muscles, joints and ligaments can be relaxed after exercise, which is helpful to eliminate fatigue.
