The old lady who fell into the water was rescued by a passing man, what is the point of learning to

In the 3-4 meters deep river, although the man who rescued people can swim, it is still very difficult to save people smoothly. But in this incident, fortunately, the two people ended up safe, and the two families also established a deep friendship because of this incident.

Through this incident, we realized that being able to swim is a very important thing. It is not uncommon for us to fall into the water or fall into the water by accident, and if we don't know how to swim, we may end ourselves up in prison.

In my personal opinion, learning to swim has the following two very important meanings, each of which is very good for me.

1. To yourself: Fitness swimming is a very physical exercise, in the process of swimming, the whole body can be reasonably exercised. Many people who like to swim not only have a good body, but also a very young body.

People who swim regularly will have a corresponding lung capacity and will be larger than the average person. For those who can continue to swim all year round, the body is much better than the average person.

Compared with other forms of exercise, swimming is also more acceptable in many cases, and it can also be adhered to for a long time to achieve the purpose of exercise.

2. To others: Saving people in dangerAfter we learn to swim, it is not only very beneficial to our own health, but also can successfully save people in danger when others are in danger.

In the face of the overboard incident that happens around us, if it is a person who can't swim, it may only be in a hurry. If you rush into the water, you may not be able to save people, but you will also be implicated, and in serious cases, you will give your life because of this.

Of course, if you are a swimmer, the situation is very different. On the premise of being able to protect themselves, they can also successfully rescue the person who fell into the water.

It is precisely because of this situation that learning to swim has become a necessary survival skill. Have you mastered this survival skill?

Strengthen the body and save people. Learning to swim can strengthen your body, keep your life safe when necessary, and save lives in times of crisis.

There are many meanings of learning to swim, you can exercise your body, you can save yourself when you are in danger, you can also lend a helping hand when others are in danger, you can enrich your hobbies, and it is also a survival skill.

Of course, with this physical exercise, you can save your own life when necessary, and you can also save the lives of others when you have the ability.

On the one hand, it can help us strengthen our body, and on the other hand, when we encounter danger, we can urgently save ourselves from others.

The meaning of learning to swim is to be able to have a guarantee for your own life safety. Being able to save your own life at a critical moment, and maybe someone else's life, I think it's very important to learn how to swim.

Learning to swim can save people's lives at critical moments, and learning to swim can strengthen the body and make your physical fitness more perfect, mainly because you can.

The first role of learning to swim is to be able to protect yourself, and if you encounter a situation such as falling into the water, you can also save yourself. The second is that when someone else falls into the water, someone who can swim can also help.

The first is to protect one's own safety and save oneself in the event of an accidental fall into the water, and the second is to help others in a critical moment, perhaps to save a life and a family. Finally, learning to swim can also exercise your body.

In fact, the biggest significance of learning to swim is not to save people, because it is very difficult to save people underwater, and the biggest meaning of learning to swim is self-rescue and exercise.

Knowing how to swim is not only a way to exercise your body, but it is also a survival skill that can be rescued after someone else or yourself accidentally falls overboard.

Learning to swim adds a life-saving skill. Swimming is a necessary survival skill, and although it is often not used, it is a life-saving skill when necessary.

When encountering such a situation, it is extremely important to take a breath before sinking, and it is also the key to survival. When sinking, you should keep your composure, close your lips, clench your teeth, hold your breath, and if you want to struggle desperately in the water, you should raise your head, tilt your body, and maintain this posture, and you can slowly rise to the surface. Once on the surface, don't lift your hands out of the water, but paddle under the surface so that your head is above the surface so you can breathe air.

If possible, remove shoes and heavy clothing, look for floaters and hold on firmly. At this time, you should call for help to pedestrians on the shore and paddle regularly on your own, swimming slowly towards the shore.

1. Grade of underground waterproof engineering.

No water seepage is allowed, and there are no wet stains on the surface of the structure.

Second, will the roof of the downstairs be wet if the bathroom leaks?

This slight water seepage can cause changes in the roof of the downstairs bathroom to yellow, and over time, mold can develop in the seepage area. With the naked eye, it is black. This can make the air quality in the restroom very poor under such conditions.

In addition, if there is a noisy circuit in the bathroom, there may be a short circuit in the electricity.

The root cause of slight water seepage in the bathroom is that there is a partial damage to the waterproofing of our bathroom, but the damage is not particularly serious. In the process of using water, there is water through this broken area, which slowly penetrates into the roof below. After the bathroom does not use water, it slowly dries out again.

That's what it shows.

Summary. No, because when they fall into the water, they are very nervous, and they will still struggle like this. A variety of different movements.

When professional rescuers continue to tread water with the same force, they slowly raise their hands from the water in turn, and we will find that the human body will slowly sink when the hands are raised, and when the hands are completely lifted out of the water, the water basically spreads to the rescuer's chin, which is very unfavorable for self-rescue.

Firefighters said that the first time for drowning rescue is often only 5 minutes, and if you fail to save yourself or others in time in such a short time, the chance of survival of the drowning person will be reduced. Therefore, it is particularly important to do a good job in drowning prevention and master scientific self-rescue and other rescue skills. People who fall into the water should hold on to the water for as long as possible until rescue forces arrive.

Will a person who has fallen from a two-meter-high bank and fallen into the river remain in the posture he was walking in?

No, because when they fall into the water, they are very nervous, and they will still struggle like this. A variety of different movements. When professional rescuers continue to tread water with the same force, they will slowly raise their hands from the water in turn, and we will find that the human body will slowly sink when the hand is lifted high, and when the hand is completely lifted out of the water, the water basically spreads to the rescuer's chin, which is very unfavorable for self-rescue.

Firefighters said that the first time for drowning rescue is often only 5 minutes, and if you fail to save yourself or inform him to save in such a short time, the chance of survival of the drowning person will be reduced. Therefore, it is particularly important to do a good job in drowning prevention and master scientific self-rescue and other rescue skills. People who fall into the water should hold on to the water for as long as possible until rescue forces arrive.

The deceased was an old man, and when he was salvaged, he seemed to be very peaceful and without any pain, as if he was asleep, maintaining his usual walking posture.

It shows that the old man may regard death as home, and he has no fear of this, and it is possible to do so blindly. That's why I didn't betray any pain and struggle.

He usually walks with one hand in front of his chest, even if he sees death as home, he will have a normal reaction, right?

Because he sees death as if he were home, he won't have any struggle, so his reaction is not very obvious.

There was blood on his forehead, but there were no stones in that river. Besides, if you fall into the water of 1.5 meters, you can't touch a stone?

It may be that the head touched the bottom of the river, which is why the blood stains appeared. It was also due to the collision.

The first responder should swim behind the drowning person and use their left hand to hold the opponent's right hand between their left arm and upper body, or drag the drowning person's head and drag them to shore in a backstroke. First aid personnel prevent drowning from holding on, affecting first aid. In case of being caught, the first responder should let go and sink, first separate from the drowning person, and then save him.

Or push the drowning person's face back, pinch the nose so that he can let go, and then save him.

If the first responder is unable to swim, he or she should immediately use a rope, bamboo pole, wooden plank or lifebuoy to hold the drowning person and drag him to shore.

If there are no life-saving materials at the scene, you should immediately call others loudly.

Self-protection in case of overboard.

In life, we will inevitably fall into the water, and how to save ourselves is a very important issue. When you accidentally fall into the water, the first thing to do is to quickly acclimatize to the underwater environment, control your breathing at a normal level, and hold your head above the water at the same time. When consciously involved, try to swim forward or roll sideways to ensure that you can run far and fall.

In addition, when we fall into the water, we should slow down the pace of breathing, minimize the waste of oxygen, and keep our hearts and minds awake and full of energy.

How to use your surroundings to save yourself.

In the process of self-rescue, the surrounding environment is very conducive to our self-rescue. When we realize that we have fallen into the water, we can try to grab the floating objects around us, such as lifebuoys, tree branches, etc., to help us stay stable in the water. At the same time, you can also use the buoyancy in the water, lie on the water, relax your body and achieve the effect of balanced breathing.

If you can't stand in deep water, you can try to use a life belt to hang on your body to reduce the burden on your body, increase buoyancy on the water, and send out a distress signal at the same time.

We can also administer first aid on our own to ensure our own safety before waiting for rescuers to arrive. After falling into the water, you should rinse your body as soon as possible to wash away parasites and bacteria, and at the same time wrap your body in dry clothes or towels to keep warm and avoid hypothermia and hypothermia. If you have foaming in your mouth or weakness in your limbs, you should immediately reduce your breathing to prevent further deterioration, while conserving your strength and waiting for rescuers to arrive.

In the journey of life, we will definitely encounter emergencies such as falling overboard, and we need to stay calm and try to save ourselves without hurrying. There are many ways to save ourselves, such as using the surrounding environment to help us save ourselves, performing on-site first aid, and so on. In the process of self-rescue, you must keep your sanity, do not waste too much physical strength and breathing, and wait for the arrival of rescuers.
