During this time, I believe that everyone will always pay attention to the "Beijing Winter Olympics".
Just so-called: ice and snow reflect the five rings, dream of yao Kyushu.
The blooming of the Beijing Winter Olympics not only showed the world a more prosperous, stronger and more confident China, but also made many people feel the charm of ice and snow sports.
Ice skating, skiing...... These seemingly cheerful winter sports are actually not so easy to operate.
Although ice and snow sports seem to be more fresh than running and jumping rope, it is easy to enhance the enthusiasm of teenagers to exercise, but this kind of exercise has relatively high requirements for lower limb strength, core control, and balance, and is a kind of aerobic exercise with high intensity.
Especially for beginners, it is not an easy task to maintain balance on ice and snow, and if the center of gravity is not well controlled, it is easy to fall or collide.
In the Winter Olympics, why are athletes required to wear "tights" in competitions?
In fact, tight tracksuits can effectively reduce drag, including reducing frictional resistance with air and differential pressure resistance, maximizing speed.
At the same time, tights with better compression can tightly wrap soft tissues and muscles, reduce the number of times athletes shake during the game, reduce athletes' soft tissue or muscle damage, and avoid excessive physical exertion of athletes.
In addition, different sports, the material of their tights also have different requirements.
For example, the alpine skiing competition suit adds cushioning materials to effectively slow the impact. The short track speed skating race suit, the overall use of high elastic cutting fabric, reduce air friction.
Once injured, do you choose hot or cold compresses?
Because snow sports are often carried out in relatively cold weather conditions, the body moves fast, and the risk of falling down increases. In the event of a collision, the risk of injury is higher.
If there is a muscle sprain, do I need hot or cold compresses? Let's first look at the advantages of two types:
1. Hot compresses
Hot compresses can effectively promote blood circulation and speed up the metabolism of the injured area, so as to strengthen the function of white blood cell engulfing bacteria in the body.
This can play a role in relieving the pain of the affected area, as well as preventing inflammation and infection in the affected area, and can also play a role in reducing swelling, stopping bleeding and soothing muscles and bones.
However, the premise of choosing a hot compress is that there is no obvious wound on the injured area, but only symptoms such as pain and bruising, or just ordinary injuries.
In this case, it is more effective to choose hot compresses, and it should be applied after the hot compresses to activate blood stasis and have an analgesic effect, only in this way can it play a therapeutic effect.
If the pain in the affected area is more serious, you should go to the hospital in time to check whether it hurts the muscles and bones, if it is not particularly serious, then you can continue to treat the drug for a period of time, so that the affected area can be restored to health.
During the treatment period, it is still possible to use the method of hot compresses to assist in treatment, but the temperature should not be too high when applying hot compresses, otherwise it is easy to burn the skin.
2. Cold compresses
On the one hand, cold compresses can effectively relieve the pain of the affected area, and on the other hand, it can also effectively reduce the chance of wound inflammation.
The use of cold compresses can also reduce muscle spasms and promote the speed of blood circulation, which in turn plays a role in relieving pain. However, for more serious sprains or strains, you should go to the hospital in time for examination and treatment.
In general, the method of cold compresses is mostly used for acute injuries, such as more obvious wounds, in this case, if the way of hot compresses is used, it will not only increase the pain but also the risk of inflammation and infection, so it is very important to choose the correct first aid method.
Don't use improper rescue methods because you are too flustered after the damage, otherwise it will only make things worse.
Is it a hot compress or a cold compress?
In this case, different rescue methods should be adopted according to the actual situation.
In case of sprains, strains, etc., you can choose cold compresses, on the contrary, if there is obvious trauma to the affected area, you should seek medical treatment in time. So as not to delay the best time for treatment, which will lead to aggravation of the injury.
As two relatively simple rescue methods, there is a big difference between the two.
If it is just an ordinary sprain, then you can use an ice pack or a cold towel to apply the wound every ten minutes, so as to reduce swelling, activate blood and dissolve stasis.
However, whether it is ice or hot compresses, you should grasp the temperature, otherwise it is easy to burn or frostbite the skin, so as not to cause the wound to worsen.
