We are the supplierof Muscle cramp self-rescue cramps in water are caused by excessive release of electrolytes in the water, cold water, excessive physical energy consumption, and insufficient preparations on land. Leg and toe cramps are the most common.
If this happens to you, first keep your body balanced in the water, straighten your legs as much as possible, then grab your ankles with your hands, hook your toes toward your body, and pull your toes toward you as much as possible until the cramps disappear. If the cramps are too heavy and the legs are shriveled and numb, you can swim to the shore while pulling, or you can call for help. Sudden sinking during swimming This hazard is common in beginner or inexperienced swimmers. During swimming, you will feel that your body suddenly loses strength, and then your body sinks. This situation is mainly due to insufficient estimation of one's own physical strength, uneven distribution of physical strength, excessive physical exertion, and no awareness of oneself.
When encountering such a situation, one must remain calm. The body is full of gas, and for a moment, the body will naturally float up. Then, stroke the small breaststroker (the hand is pressed down to the water), and the small breaststroke leg (mainly the calf, and the ankle is circled from the inside to the outside), and gradually transition to breaststroke. If there are auxiliary facilities such as water lines around you, you can take a rest for a while before swimming.
When swimming in natural waters surrounded by water plants, you must first observe the underwater environment. If you unfortunately encounter water plants or fishing nets entangled, you must remain calm and do not struggle. In such a situation, only by staying calm can there be a chance of relief. The sooner the entanglement is discovered, the easier it is to unwind. After being entangled, you should first relax your body, observe the entanglement, and find a way to get rid of it. If you can't get rid of it, you can call for help. (The water plants and the entangled rope tip will spread outward and upward as the body relaxes, as long as you carefully look for the root cause, you will be relieved.) Rescue and self-rescue when you encounter danger when saving others.
When swimming, it is inevitable to encounter others in water. When others are in danger, we all need to extend our hands to rescue. However, when we rescue the drowning person, the drowning person is confused due to panic, fear, and often grabs the lifesaver in the panic. It is possible that we are carrying out hauling. We have been caught or hugged before, in which case we need to calmly use the technique of release, get rid of the drowning person, and then rescue.
Waiting for rescue If the drowning person is physically strong in the water, scratching and scratching, the lifesaver can be not far from the drowning person, face the drowning person, lift one foot under the horizontal surface, face the drowning person, wait and persuade the drowning person ( To prevent the drowning person from grabbing and hugging), rescue the drowning person when their physical strength weakens. The drowning person grabs the rescuer's wrist to release the method. If the rescuer's one hand is grasped by the drowning person with both hands at the same time, the grasped hand should make a fist, and the other hand should pass between the drowning person's two arms from below. The grasping hand twitches downwards, forcing the drowning person's thumb to loosen before rescue. If the lifeguard is caught by the drowning person with one hand at the bottom, it is also relieved. The difference is that the lifesaver passes between the two hands of the drowning person with one hand from above, and clenches the grasped hand and twitches upwards. The lifesaver is the drowning person hugging the neck from the back. The rescuer presses the back of the drowning person's hand with one hand and the other hand against the elbow of the same hand of the drowning person. Press down hard on the back of the hand to release it.
At the same time, hold the drowning person's wrist, turn the drowning person with their backs to themselves, and carry out hauling. The rescue method of the drowning person holding the waist in the past, because of the drowning psychology, often clings to the waist of the rescuer and makes the face close to the abdomen of the rescuer, which makes it difficult to release. At this time, the lifesaver should use the principle of the human head posture reflex, as long as the drowning person's jaw is supported with one hand, the other hand is close to the other side of his head, and the drowning person's head can be turned slightly with both hands. It lets go and leaves the lifesaver to achieve the purpose of liberation. The lifesaver should approach the drowning person from behind and carry out hauling.
First, after the rescuer is hugged, touch the finger of the drowning person with his hand, find his index finger or ring finger, grab it and force it to separate outwards, and then separate the drowning person's hands. Stretch up and down, then release the down-stretching hand, and immediately retreat behind it until the drowned person calms down before hauling.
The rescue method of the lifesaver caught by the drowning person's hair If the lifesaver's hair is caught, the lifesaver should press the drowning person's hand with the same hand as the drowning person (hand with crossed position), look for the little finger of the drowning person's hand, the body Sink, at the same time lift his hand up with his hand, and push his elbow with the other hand, so that the drowning person turns his body and is hauled to himself.
