Does exercising to lose weight without sweating mean there is no weight loss effect?

　　Many women who want to lose weight like to exercise to lose weight, thinking that the more they sweat during exercise, the better, and the more effective weight loss will be. If they don’t sweat, they will complain that it has no effect. But is this really the case? Let’s listen to what experts say.

　　The more you sweat during exercise, the better.

　　Many people will sweat after just a little exercise, while some people often exercise for a long time without sweating much. What is going on? Experts say that under normal circumstances, the greater the intensity of exercise, the more sweat is produced, but the amount of sweat produced during exercise varies from person to person. People with a large number of sweat glands sweat relatively more. The amount of water consumed before exercise also has an impact on sweating. If you drink a lot of water before exercise, it will lead to an increase in body fluids and increase the amount of sweat. In addition, it also depends on the individual's physical fitness. People with strong physiques have stronger muscles and sports organs. healthy , even if you perform high-intensity exercise, it will be effortless and you will naturally sweat less; on the contrary, people with poor physical fitness will sweat profusely if they move a little.

　　Experts say that the more you sweat during exercise, the better. As long as you sweat slightly, moderate exercise is the most important. Exercise can burn calories, improve microcirculation, and regulate the body nerve sensitivity. People always regard sweat as exercise gist, but sweat-free exercise can also prevent or reduce various chronic disease risk, research shows that working in the garden for just one hour a week can reduce the risk of a heart attack by 66%. Walking for one hour per week can reduce this risk by 73%. In the Netherlands, people who walk or cycle for at least one hour a week have a 29% lower mortality rate than those who are inactive, and can also help reduce the risk of stroke, diabetes, dementia, fractures, breast cancer and colon cancer risk.

　　There is no scientific basis for sweating to lose weight

　　It is understood that there are about 3 million sweat glands distributed in the human body. One end of it is the secretory part, which secretes sweat; the other end is the excretory part, which opens directly into the skin surface, called sweat pores. The discharge of sweat regulates body temperature and also discharges some metabolic waste. Under normal circumstances, sweating is a reflex activity, and the secretion of sweat glands can be caused by thermal stimulation or mental stress. When heat causes blood vessels to dilate, the water in the blood transfers heat to the surface of the skin, and then evaporates with sweat, transferring the heat to the surrounding environment. In high-temperature environments, the amount of sweat produced by the human body can be as high as 8-12 liters per day.

　　Of course, some diseases can also cause the body to sweat. If you suffer from rheumatism or tuberculosis, you will sweat a lot. The sequelae of encephalitis are often accompanied by sweating. If this happens, you should seek medical advice in time. Hospital Carry out relevant inspections. “There is not much basis for the view that "sweating all over will help you lose weight", because the process of sweating is mainly to dissipate excess heat from the body. A large amount of sweating causes the human body to lose water, which can only temporarily reduce weight. Real weight loss should reduce fat, perform appropriate exercises every day, and consume a certain amount of calories, so as to achieve effective weight loss.

　　Pay attention to the following points after exercise

　　Regarding sweating during exercise, you should also pay attention to the following situations:——

　　Not sweating during exercise can lead to heatstroke. Many people often do not sweat much after exercising for thirty or forty minutes, but the surface of their skin is very hot. This is because the sweat in the body cannot be discharged, causing an imbalance in body temperature regulation. If you feel your body is burning, you should stop exercising immediately, otherwise you may easily develop symptoms of chest tightness and dizziness. At this time, you can drink some ice water, apply a cold towel on your forehead, or urinate in time, which can lower the body temperature.

　　Be wary of rheumatism if you sweat profusely during exercise. Many people believe that the more you sweat during exercise, the better the effect. In fact, a large amount of sweat will take away potassium ions, sodium ions, salt and other substances from the human body. For people with poor physical fitness, excessive sweating may cause dehydration of the human body, resulting in dizziness, dizziness, stomach ache and other symptoms. In addition to poor physical fitness, if you also sweat profusely when doing sweatless exercises such as walking and Tai Chi, you should go to the hospital to check whether you may have rheumatism.

　　Don't take a shower immediately after working out and sweating. Just after exercise, the human body is still in a state of strong metabolism and dilated blood vessels in the skin. If you take a bath immediately at this time, the skin will be stimulated and the skin blood vessels will contract through nerve reflexes, which will make it difficult to dissipate heat and increase body temperature. At the same time, the blood flow to the skin decreases and the amount of blood returned to the heart increases, increasing the burden on the heart. Since sweat contains a lot of sodium chloride, if you sweat a lot, you should supplement your diet with salt and calcium. Therefore, in summer, you should drink some salt water after exercise, and then rest for about an hour before taking a bath. Of course, it is best to take a bath with warm water.

　　Precautions for exercise and weight loss

　　1. Varies from person to person. Dieters must undergo a physical examination before exercising. If you suffer from serious coronary heart disease People with diseases such as high blood pressure, hepatitis, and nephritis are not suitable for a large amount of physical activities. They must first treat the disease and choose gentle and appropriate activities such as walking and Tai Chi. The elderly, children, pregnant women, etc. should also choose their own appropriate sports.

　　2. Step by step. Obese people usually lack physical exercise and have poor cardiopulmonary function and bone and joint flexibility. Therefore, it is not advisable to exercise with a heavy load at the beginning. The amount of exercise should be increased step by step. It usually takes 2-4 weeks to adapt.

　　3. Be well prepared. You should do some preparatory activities before each exercise, such as moving the upper and lower limbs and waist to fully activate the ankle joints, leg muscles and tendons, increase the gas exchange of the lungs, and increase the blood output of the heart to avoid muscle and ligament strains, palpitations and shortness of breath.

　　4. Exercise in moderation. If the amount of exercise is too small, the purpose of weight loss will not be achieved. If the amount of exercise is too much, side effects will occur. Especially obese people and the elderly with other serious chronic diseases must pay special attention. Generally speaking, the amount of exercise should be at moderate intensity, and the post-exercise pulse rate should not exceed 150 beats per minute for young people and 110 beats per minute for the elderly. Symptoms such as dizziness, nausea, vomiting, and pale face should not occur during exercise. My muscles are sore after exercise, but my sleep and appetite are normal. If symptoms such as headache, loss of appetite, and insomnia occur, it means excessive exercise.

　　5. Relax after practice. Relaxation activities are also called tidying up activities. After each exercise or between exercises, do some slow-paced activities such as walking, jogging, deep breathing, etc., so that the heart, breathing, blood pressure, etc. can return to normal from the exercise state as soon as possible.

　　6. Be persistent. Physical exercise must be consistent. You cannot practice whenever you want, or just don't practice when you don't want to. Practicing intermittently is not conducive to weight loss and health. Parents should supervise children's exercise, lead by example, and practice it.
