In the era of “thin” beauty, weight loss is always the theme of the times. There are a lot of ways to lose weight, and exercise to lose weight is recognized by everyone, and running is the most common way of exercise to lose weight. In the process of running, the human body will sweat a lot, so in a lot of sweat at the same time, the fat will also be consumed with the sweat? Is it possible to achieve the effect of weight loss through running? I believe that this is the most concerned issue for runners. As we all know, people sweat when they are hot. When running, people’s metabolic ability will be enhanced, the body’s energy storage material will be metabolized into heat energy, people’s body temperature rises, sweat glands will release sweat. When sweat evaporates, it lowers the core temperature, keeping the body temperature as close as possible to 37°C, which is the most comfortable level for the human body to feel. If sweating is not done in a timely manner, overheating of the body temperature can occur, leading to fainting, heat stroke, and even death. As you can see, it is important for the body to perspire. But today we want to know is in the process of sweating, the body fat is also in a large amount of consumption? The answer is not, the reason is: under normal circumstances, sweating is a reflex activity, the secretion of sweat glands can be caused by warm stimuli or mental tension. When heat causes vasodilatation, water in the blood transfers heat to the surface of the skin and then evaporates with the sweat, transferring the heat to the surroundings. In hot environments, the human body can sweat as much as 8-12 liters per day. This loss of water does make the number on your scale a little smaller, but it’s only temporary, as long as you rehydrate in time, your weight will go back up. This means that the sweat a person breaks during a run is primarily water, not fat burned. Sweating more does not necessarily mean that more fat is consumed. The real weight loss should be to reduce fat, proper exercise every day, consume a certain amount of calories, so as to achieve effective weight loss. Weight loss is a long-term process, not overnight. Running can indeed consume a certain amount of calories, which is favorable for weight loss, but this has little to do with how much sweating, not much. Losing weight still requires burning more calories in order to reduce the fat on your body.
