Can drinking hot water help improve your exercise performance?

Sports performance is affected by factors such as body temperature regulation and fluid balance. If the exercise time exceeds 60 minutes, the body will sweat a lot, resulting in the loss of sodium, potassium and water, which in turn causes decreased judgment, muscle cramps, etc. Therefore, it is very important to replenish water in time.

Generally speaking, sports drinks are not needed for exercise of less than 60 minutes. If the exercise lasts for more than 60 minutes, it is best to use sports drinks to replenish electrolytes and lost fluids and reduce fatigue.

There is no consensus on the effect of drinking cold water on athletic performance. Some studies have shown that drinking cold water can help lower core body temperature faster and improve exercise endurance. Other studies have shown that although drinking cold water can lower core body temperature, it has no significant effect on improving athletic performance.

It should be noted that everyone's intestines have different tolerance to water temperature. For some people, drinking cold water will cause gastrointestinal discomfort and cramps, which will affect athletic performance.

In summary, whether to drink hot or cold water during exercise depends on the individual.

Should you take a shower immediately after exercising?

In the eyes of many people, there is nothing more refreshing than taking a shower after exercise. However, it is best not to take a shower immediately after exercise.

When people exercise vigorously, blood will be redistributed, and the heart will pump more blood to the muscles. After exercise, the brain remains in a highly tense state. This circulation pattern of the cardiovascular system takes a certain amount of time to return to normal. If you take a shower immediately after exercise, it may induce a variety of adverse consequences.

Taking a cold shower will cause the cold stimulation to further excite the sympathetic nerves, which may induce cardiovascular and cerebrovascular events such as cerebral hemorrhage and myocardial infarction in patients with hypertension.

Taking a hot bath will cause further dilation of peripheral blood vessels (muscles and skin), further aggravating ischemia of organs such as the brain. In addition, the loss of body fluids caused by exercise can induce fainting, etc.

So, how should you shower after exercise?

1. The best time to take a bath is about 30 minutes after exercise. During this period, you should do some relaxing exercises, dry your body with a towel to avoid catching cold, and replenish water or electrolytes.

2. It is best to take a bath in alternating hot and cold mode.

The hot and cold water alternation mode is an effective way to stimulate blood circulation, help muscle recovery, improve body stiffness, and even improve immunity and improve skin aging. The water temperature of a cold shower should be between 10-15℃, and the water temperature of a hot shower should be between 35-40℃. The alternating hot and cold time is 1-2 minutes.

Who is healthier, the one with a pale face or the one with a red face after exercise?

In general, exercise causes breathing to become faster, delivering more oxygen to the blood. The heart beats faster, causing the small blood vessels and capillaries to dilate, increasing blood flow to the muscles, delivering oxygen to the muscles and removing waste products. The blood vessels in the skin dilate and become red, especially on the face, which has a rich network of capillaries.

However, if the blushing is accompanied by dizziness, nausea or fatigue, it may be due to other reasons (such as dehydration, heat stroke, high blood pressure, etc.), and you should stop exercising immediately. In addition, rosacea and lupus erythematosus can also cause the face to become particularly red.

The most common reason for blanching during exercise is a redistribution of blood supply. The blood that normally flows through the small blood vessels in the skin is pumped to the muscles to meet the increased demand for oxygen in the muscles. This is more common in cold weather, when there is less blood demand from the skin.

If your face is too pale, you should also be careful of other diseases, such as anemia. If you have high blood pressure, diabetes, or are accompanied by dizziness, precordial discomfort, etc., you should seek help from a professional doctor.

How to exercise scientifically?

1. Spend about 10 minutes warming up.

2. Don't rush for success, and gradually improve your athletic ability and intensity. Excessive exercise intensity can lead to sports injuries, such as stress fractures, joint and muscle pain, and tendon and ligament injuries. Combining different types of exercise can help avoid similar situations.

3. If you are sick or feel very tired, you should stop exercising or reduce the intensity of exercise. When exercising, pay attention to replenishing water and electrolytes.

4. Choosing appropriate sports equipment, scientific exercise posture and techniques are also very important.

5. Pay attention to extreme weather and do not exercise at times and places that are not suitable for exercise.
