Do you need to wear underwear when swimming?

It depends:

1. If you are wearing a tight swimsuit, you don't need to wear underwear. Because the design of the swimsuit is more scientific and reasonable, it meets people's sports requirements. It has good elasticity and is always stretchable. The general swimsuit material is also non-irritating to the skin. There is also a lining in the crotch of the swimsuit for basic friction protection. However, underwear is different. When the underwear is soaked, it is easy to collect water, and you don't know if it will be on your body in the next second or at any moment.

2. If you are wearing a loose swimsuit, it is best to wear tight underwear. Because during swimming, especially breaststroke, the vagina will also open. And because the swimming trunks cannot fit tightly to the body, action and reaction forces will be generated during exercise. The water in the swimming pool will flow into the vagina and bring bacteria into the vagina. If sexually transmitted diseases are spread, it will not be worth the loss. Therefore, it is recommended to wear underwear.

Is swimming good for your heart?

The benefits of long-term swimming to the cardiovascular system are that it increases the volume and mobility of the heart, makes the myocardial contraction stronger, slows the heart rate when at rest, increases the stroke volume, thickens the blood vessel walls, increases their elasticity, and improves the efficiency of the cardiovascular system.

At the same time, swimming creates resistance with water, which has the effect of losing weight and maintaining body shape, which is beneficial to control blood pressure, blood lipids, blood sugar, etc. However, swimming can also cause a sudden increase in blood pressure in patients with hypertension, which may induce the risk of stroke and cerebral infarction.

At the same time, swimming involves a lot of exercise, and heart disease patients may suffer from insufficient blood supply during exercise, leading to coronary artery ischemia, vascular spasm and other phenomena, which may lead to myocardial infarction and sudden death.

How to swim to lose weight faster

1. Freestyle vs. Breaststroke

Usually, the speed and intensity of the breaststroke are not as good as the freestyle. The freestyle is a continuous and fast movement. If the time is compared, the calories consumed by the freestyle are three times that of the breaststroke. In particular, many people like to swim the "head-up breaststroke", which is an effortless way of swimming. Therefore, if you want to use swimming to lose weight, it is best to choose the freestyle. However, the freestyle and the breaststroke will exercise different parts of the body. The freestyle mainly exercises the arms and core, while the breaststroke is the thigh, which is suitable for sculpting lines. People who can do both can use them alternately.

2. Swimming pool water temperature

The higher the body temperature, the higher the fat burning rate. Swimming already takes a long time to achieve the fat burning rate of general exercise. If the water temperature is too low, it will take longer. And if you take a short rest, you have to spend more time waiting for the body temperature to rise.

3. I feel very hungry after swimming, so I eat more

Everyone may have the same experience that they always feel very hungry after swimming. That's because swimming really uses the muscles of the whole body to fight against the buoyancy and resistance in the water, so the body is more easily tired. If you are a person who can't control your appetite, you may consume more food calories than usual after swimming. Not only will you not lose weight, but you will gain weight.
