In fact, the amount of sweat during exercise varies from person to person. Some people sweat a lot and naturally sweat a lot. Secondly, it depends on the physical quality of the individual. People with strong bodies have healthier muscles and motor organs. Even if they exercise harder, they naturally have no strength and sweat less. On the contrary, people with poor health will sweat a little. So what effect does excessive sweating have on the body? The following powerful xiaobian tells you to reduce your athletic ability. If you sweat too much during exercise, the water in your body will be greatly reduced. If water is not replenished in time, it may lead to dehydration. At this time, your body will be tired and dizzy, and even faint and unconscious in severe cases, but you can't continue to exercise. After sweating a lot, potassium ions and sodium ions in the blood are lost. Potassium is an important element to maintain water and salt metabolism in the body. Lack of potassium can lead to weakness of limbs, and low sodium can lead to loss of appetite, nausea and low blood pressure. If these nutrients are not supplemented in time, it will affect future exercise. Sweating a lot after exercise and supplementing the missing nutrition in time can help us lose weight better.
