Of course, the benefits of swimming are not only the benefits mentioned above. The benefits of swimming mentioned above are just some of the benefits of swimming. In fact, swimming can also strengthen the blood circulation of the human skin and enhance resistance.

During swimming, due to the stimulation of water temperature, the body participates in an important regulatory role in order to ensure sufficient temperature. The stimulation of cold water can cause the skin blood vessels to shrink to prevent heat from spreading out of the body.

At the same time, the body has stepped up the production of heat, dilates the skin blood vessels and improves the blood supply to the skin blood vessels. This way, long-term persistence in exercise can strengthen the blood circulation of the skin.

In addition, water is a very soft liquid. Due to the effect of water waves, it constantly rubs the human skin, so that the skin can be relaxed and rested better. Therefore, people who often participate in swimming exercises have smooth, white and soft skin.

Moreover, when people are swimming, water plays a good massage effect on the skin, sweat glands, and fat glands, promoting blood circulation and making the skin smooth and elastic.

In addition, the salt contained in the sweat flowing out during ordinary exercise will cause some irritation to the human skin, and gradually the skin will begin to grow old. When exercising in water, the water flow greatly reduces the irritation of the salt in the human sweat on the skin.

Moreover, the water temperature in the swimming pool is often 26 degrees to 28 degrees. Soaking in the water dissipates heat quickly and consumes energy. In order to replenish the heat emitted by the body as soon as possible to provide the need for hot and cold balance, the nervous system responds quickly. It accelerates the human body's metabolism, enhances the body's ability to adapt to the outside world, and resists the cold.

People who often participate in winter swimming will not easily catch colds due to improved body temperature regulation function. They can also improve the endocrine function of the human body, increase the pituitary function, thereby improving resistance and immunity to diseases.

In modern society, as society develops faster and faster, people's living standards are gradually improving, and accordingly, people's bodies have also begun to experience a lot of obesity. Now obesity has become a bump in the hearts of many people. Swimming can also help people lose weight, strengthen their body shape, and the effect of losing weight and building their body shape is extraordinary.

When swimming, the body is soaked directly in water. The water not only has great resistance, but also has very good thermal conductivity and fast heat dissipation, so it consumes a lot of heat.

It's like a freshly cooked egg, which cools in the air far faster than in cold water.

Experiments have proved that the calories consumed by a person who runs in a standard swimming pool for 20 minutes are equivalent to 1 hour on land at the same speed, and the calories consumed by staying in water at 14 degrees for 1 minute is as high as 100 kcal, which is equivalent to the calories emitted by 1 hour in air at the same temperature.

In addition, swimming weight loss can avoid sports injuries to the lower limbs and waist.

When exercising on land to lose weight, due to the large weight of obese people, the body (especially the lower limbs and waist) has to bear a large gravitational load, which reduces the ability to exercise. It is prone to fatigue, which greatly reduces the interest in weight loss and exercise, and can damage the joints and bones of the lower limbs.

Swimming events are carried out in water, and a considerable part of the weight of obese people is subjected to the buoyancy of water, which makes the lower limbs and waist much easier, and the risk of joints and bones is greatly reduced.

It can be seen that exercising in water will make many people who want to lose weight achieve twice the result with half the effort, so swimming is one of the most effective aerobic exercises to maintain a body shape.

As for the ability of swimming people to build body shape, this is because when swimming, people usually use the buoyancy of water to lie on their backs, and their whole body is relaxed and stretched, allowing the body to develop in a comprehensive, symmetrical and coordinated manner, so that the muscle lines are smooth.

Moving in water reduces the impact of the ground on the bones during ground movement, reduces the chance of bones being damaged, making bones less likely to deform.

The resistance of water can increase the intensity of people's exercise, but this intensity is different from the equipment training on land. It is very gentle. The intensity of the training is easily controlled within the aerobic domain and will not grow very rigid muscle mass, which can make the lines of the whole body smooth and beautiful.

Last but not least, swimming can also increase the body's ability to adapt to temperature. This is because people do not have much clothing to protect themselves when swimming, so they have a certain effect on the body's resistance to cold, especially winter swimming.

Of course, you still need to pay attention to some precautions when swimming.

1. When children are swimming, they must be guided by their parents (guardians).

It is most likely that children will have problems when swimming alone. If your companion is not a parent (adult), it is difficult to ensure that you can get proper assistance when there is a danger.

2. People with illness should not go swimming.

Patients with chronic diseases such as otitis media, heart disease, skin disease, liver and kidney disease, hypertension, epilepsy, red eye disease, etc., as well as colds, fever, mental fatigue, and physical weakness, do not go swimming, because the above-mentioned patients participate in swimming, which not only aggravates the condition, but also prone to cramps, unexpected coma, and life-threatening. Moreover, infectious patients are prone to spread the disease to others. In addition, female students should not swim during menstruation.

3. After participating in strong physical labor or strenuous exercise, you cannot jump into the water immediately to swim, especially when you are sweating and feverish all over. You cannot go into the water immediately, otherwise it will easily cause cramps, colds, etc.

4. Cold, sick, physical discomfort or weakness, after meals, on an empty stomach, and drinking alcohol should not be suitable for swimming.

5. Polluted (poor water quality) rivers, reservoirs, rapids, intersections of two rivers, and rivers and lakes with drops are not suitable for swimming.

Generally speaking, it is not advisable to swim in rivers and lakes with unknown water conditions. In severe weather such as thunderstorms, winds, sudden changes in weather, etc., it is not advisable to swim in such a sudden weather. Swimming in such a sudden weather is very likely to cause problems.

6. It is best to experience the water temperature before entering the water. If there is too cold or overheated water temperature, try not to rush into the water. The water temperature of the pool water will affect blood circulation, heart, blood pressure, breathing, metabolism, human skin and muscles.

7. Before going into the water, you must prepare for activities on the shore. Warm up for 10 to 15 minutes and move the joints and muscles in each part. Otherwise, sudden and intense activities may easily cause muscle injury or other accidents.

For example, before going into the water, you can use raising your legs high, squatting down and standing up and other exercises to move your body.

8. Never dive blindly to avoid your abdomen and testicles being directly hit by the water surface due to improper diving. If you want to dive, you must follow the instructions of a special coach, otherwise it is best not to dive.

9. When swimming, you also need to pay attention to protecting your eyes. It is best to wear goggles. The damage to your eyes is also very harmful. When swimming by the sea, you should also prevent sunburn and pay attention to the ebbing time.

10. After swimming, you should rinse your whole body with clean water to avoid any disease transmission.

11. After swimming, you can restore your physical strength by replenishing sports drinks, relaxation training, breathing debugging, hypnosis hints, psychological adjustment, massage recovery, and roaming in the water.

12. We must fully understand the specific manifestations of these symptoms such as leg cramps, dizziness, headache, nausea, vomiting, chest tightness, ear pain, tinnitus, abdominal pain, abdominal distension, and itchy eyes, and know some solutions to these symptoms.

13. It is also important to note that it is best not to swim for some people with weak constitutions, because swimming can easily cause some diseases, such as conjunctivitis, otitis media, sinusitis, pharyngitis, contact dermatitis, allergic dermatitis, aspiration pneumonia, etc.

In short, swimming is not as simple as people think. Swimming is actually a very responsible sport.

"Okay, the monkey won't say these words. Now the most important thing is to pay attention to the movements of the brothers Xuchang and Xu Jie before. We cannot lose them, otherwise our fate is conceivable. Monkey, you have learned "Hawkeye" so, I will leave this matter to you to monitor Xuchang and Xu Jie's movements. Monkey, now it's up to you!"

"Don't worry. Brother, I won't let Xuchang and Xu Jie escape from my sight."

The monkey answered confidently. With the help of "Hawkeye", and in the endless sea with no cover, the two brothers Xuchang and Xu Jie did not want to escape his surveillance.

If the two brothers Xu Chang and Xu Jie could escape the monkey's surveillance like this, the monkey would go back and find a piece of tofu and kill him!

The monkey has such confidence, which is actually because of the powerful role of "Hawkeye" in surveillance. "Hawkeye" is an extremely powerful reconnaissance martial art. After the warrior practices "Hawkeye", his eyes are actually the same as those of an eagle, and he can clearly see things a few kilometers away.

Among birds, eagles have the best vision, not only have a wide field of vision, but also have extremely sharp eyes. Therefore, people often use the eyes of eagles to describe a person's sharp eyes.

So why does the eyesight of an eagle be so good? This is because the eyes of an eagle have two fovea, the central fovea and the lateral fovea, which makes the field of vision of an eagle similar to spherical shape, so the field of vision is very wide.

In addition, Hawkeye's pupils are also very large. Generally speaking, the larger the pupil, the higher the resolution, so they can clearly see the movement of prey on the ground from a high place.

A male eagle can detect prey 30 times the distance from the human eye. Even if it flys at an altitude of 2,000 meters, they can accurately detect and identify rabbits, mice and small animals that can become food in the water.

After aiming at the prey, they will dive down and nimblely chase the prey that is escaping desperately. Once they use their powerful claws to catch the prey, they will dismember the prey with their sharp and strong beak, and then have a full meal.

Scientists' research shows that the denser the visual nerves on the retina in the eyes, the more image points the eyes can capture. Correspondingly, the images that the eyes can see are clearer, and the visual nerves in the eyes of the eagle are very dense.

It is also because of this that the eagle's eyes can see such a long distance. Even when the eagle is flying at high speed in the sky, it can easily see what is on the ground clearly. After it finds its prey, it launches an attack without hesitation...

Therefore, if a person has such good vision, we can read newspapers 30 meters away or even further away.

It is precisely because the eyes of eagles are so strong. Therefore, in the world, many countries are studying related things. They want to make the eyes of human eyes as strong as those of eagles.

However, there are no substantial results in such research.

The most important result is that the US e2 early warning aircraft, named Hawkeye, which is also another way to achieve Hawkeye vision. Well, it can actually be regarded as a self-deception. Haha...

However, something that humans cannot achieve by using technology. Zhao Chaogang achieved through the knowledge of cultivation.

"Eagle Eye Kung" is actually because Zhao Chaogang envies the powerful vision of the eagle's eyes, and a kind of exercise that has been carefully studied to allow ordinary warriors to achieve the eyes of the eagle's eyes after practicing.

The "Eagle Eye Kung" produced by Zhao Chaogang is actually based on some secret methods of cultivation in Haotian Xiaolingtian and some auxiliary methods of cultivation. Finally, Zhao Chaogang combined some acupoints recorded in traditional Chinese medicine that are beneficial to the eyes in the human body. Once these things are combined, Zhao Chaogang's "Eagle Eye Kung" is completed.

Of course, the "Hawkeye" technique seems very difficult. After all, it requires people to have the same eyes as the eyes of an eagle. They have a strong vision and can see things two kilometers away clearly. This thing seems really difficult, but to put it bluntly, it is a very simple technique.

There are many acupoints in the human body that are very meaningful to the human eyes. Long-term health care actions on these acupoints will be of great benefit to the human eyes. At least, the chance of myopia will be much smaller.

Such as Qingming acupoint, Zanzhu acupoint, Sibai acupoint, Temple acupoint, Hegu acupoint, etc. These acupoints are beneficial to human eyes. Regular massage of these acupoints can help people's eyes.

Some of the eye exercises we do now are actually massages these acupoints.

Jingming point: Jingming, comes out of the foot Taiyang bladder meridian. The five meridians of the hand and foot Taiyang, foot Yangming, Yin Qiao, and Yang Qiao are intersecting.

The depression slightly above the inner canthus corner of the eye is in the medial ligament of the orbital inner lid, and the deep part is the rectus muscle in the eye; there are medial canthus movements, veins and trolleys up and down movements, veins, and veins above the deep layer, and veins are the trunk; there are upper and lower nerves of the trolleys, deep layer is the ophthalmic nerves, and nasal and ciliary nerves above.

It is mainly used to treat eye diseases such as redness, swelling and pain, dizziness, and myopia.

Zanzhu point: The name of the meridian point, from the Acupuncture Jia Yi Classic, also known as the Eyebrow, Eyebrow, Yuanzai, Zhiguang, Lunar Light, Bright Light, Guangming, Yuanzhu, belongs to the Foot Sun Bladder Meridian. On the face, when the eyebrows are in the sinking, the supraorbital notches.

It is distributed with medial collars and frontal artery and veins. It is mainly used to treat headaches, dizziness, cataracts, red and swollen eyes, tears in the wind, myopia, eyelid tummy, eyelid tummy, eyebrow ridge pain, as well as acute, chronic conjunctivitis, facial nerve paralysis, etc.

,.No moxibustion.

Temple: The temple is in front of the auricle, on both sides of the forehead, and above the extension line of the outer corner of the eye. Temple is called "the strange point of the meridian" in traditional Chinese medicine, and is also one of the earliest "fatal points" listed as key points by various martial arts and boxing books.

According to Shaolin Fist, once the temple is touched, "the light will faint, and the worst will die." Modern medicine has proved that hitting the temple can cause a person to faint briefly or cause concussions to lose consciousness.

The temple can be said to be one of the most important acupoints in the human body. It cannot be easily hit because the temple is the weakest part of the skull bone plate.

The temple is the intersection of the parietal bone, frontal bone, sphenoid bone and temporal bone, which is called the "wing point" or "wing separator". This is the thinnest part of the skull bone plate and is a fragile bone.

The skull is a hard layer of bone plates, which protects the brain. The skull bone plates vary in thickness, with an average thickness of 5 mm and a thickest part of 1 cm. The thickness of the bone plates at the temple is only 1-2 mm, which is the weakest part of the skull. If violently hit, it is easy to form a fracture. After a fracture, it can directly affect the function of the brain.

Also, there are numerous sources of bleeding in the deep skull of temples.

In this part of the skull, blood vessels are distributed quite abundantly, thus forming many sources of intracranial hemorrhage. The middle meningeal artery, which originates from the internal jaw artery, walks upward along the temporal bone scales in the epidural dural, and the partial branches of the temporal bone scales at the temple are the front and back of the middle meningeal artery. At the same time, the middle meningeal vein is also accompanied by the middle meningeal artery.

Under the deeper dura in the cranium, there are also cortical arteries and veins in the temporal lobe of the brain.

The violent blow to the temple can not only damage the middle meningeal artery due to fractures of the skull temporal scale, but also often damage the middle meningeal artery and veins while the skull is intact, and form epidural hematoma at the base of the middle cranial fossa.

The rupture of the middle meningeal artery forms a hematoma, which is not only very rapid, but also has extremely serious consequences.

The rupture of the middle meningeal artery can cause a person to fall into a coma immediately. The intermittent awakening period after coma is very short, at most less than 1 hour, and at least only 10 minutes. It is often completely unconscious after two hours of injury. If the bleeding cannot be effectively stopped 6 hours after the injury, it can be fatal.

Injuries in the two anterior and posterior branches of the middle meningeal artery and in the cortical groove of the temporal lobe of the brain will form a huge intracranial hematoma centered on the temporal area in the deeper layer of the meningeum. Because the bleeding site is deeper, it is more dangerous. (To be continued)
