The dragon and tiger leap into the auspicious stars, and Furui welcomes the spring and celebrates the New Year. On the occasion of the Spring Festival, Beijing Science and Technology News carefully planned and launched a series of articles with the theme of "Science and Technology for the New Year" from February 9 (Chinese New Year's Eve) to February 17 (the eighth day of the first lunar month), so that this Spring Festival holiday is full of strong "science and technology flavor".
Interview with the experts:
Zhao Bin (Chief Physician, Emergency Department, Beijing Jishuitan Hospital)
Wonderful holiday
Lazily nestled in the sofa to watch videos
It is the favorite of many people
I believe that many friends
I've all brushed it up
Clothing
A chic figure galloping on the snow field
They are like in Xianxia works
An ancient knight of Edgeworth's flight
Fight the sword rivers and lakes, happy and revenge
It's fascinating
It also lit a lot of maybe positive
"Comfortable nestled in the sofa" people's enthusiasm for skiing
But as a beginner
You know skiing that seems to be chic
In fact, are these "mysteries" hidden?
When is the best time to ski?
Skiing at different times of the day will have different feelings.
After 10 a.m., the surface of the snow slowly melts and the snow becomes softer, making it feel best for skiers, neither soft nor hard, and the skiing is very pleasant.
In the afternoon, the humidity of the snow increases, the friction increases, and the gliding speed is slower, making it relatively easier for beginners to control the skis. For advanced skiers, wax the underside of the skis to reduce frictional resistance during the run.
As the sun weakens and the temperature drops, the snow begins to crystallize, and the snow becomes harder, much like compacted powdery snow, with less friction and faster skiing, making it less suitable for beginners who are new to skiing.
Do you have to follow the "traffic rules" for skiing?
Just as you need to follow the traffic rules when driving a vehicle, you also need to follow the rules when skiing. On the slopes, people need to follow the 10 International Ski Federation Safety Guidelines (hereinafter referred to as the guidelines) in order to maintain a safe and smooth flow.
When driving, drivers need to be careful not to exceed the speed limit. The same is true on the slopes, where speeding violates the requirement of "maintaining a controlled speed and movement and keeping a certain distance from others" in the guidelines. And the danger factor of speeding is very high, which may not only make you fall badly, but also threaten the safety of others.
At the same time, when skiing, it is also necessary to comply with the rules of timely movement similar to the traffic regulations, which require "do not stay on the slope without an emergency, move to the edge of the slope as soon as possible after falling, and walk on the edge of the slope when you need to hike (to pick up fallen poles and snowboards)" to avoid being hit by others.
In addition, just as you can't drink while driving, you can't drink alcohol before skiing. Because this sport requires precise control of movements, alcohol not only affects control and increases the likelihood of falling, but also makes people seek excitement and make dangerous movements. It should be noted that not only should you not ski after drinking, but there is also a certain risk of drinking alcohol within 24 hours, and due to the influence of hangover and residual alcohol, even if you drink alcohol the night before skiing, the blood alcohol concentration may still be high, and the risk of skiing injury will also increase.

About skiing
Many people will feel that the risk factor is too high
I'm worried about sports safety
As a newbie
I don't know much about the precautions involved
To help you understand quickly
The reporter had a special interview
Zhao Bin, chief physician of the emergency department of Beijing Jishuitan Hospital
Help you answer your questions
Why is it often said that the end of skiing is orthopedics?
The complex environment outdoors and the acceleration of the ramp slide test the control ability and balance of all parts of the body...... A combination of factors has contributed to the fact that skiing is prone to falls. As for us with a "flesh and bone" body, falling on the hard surface of the snow will cause some soft tissue damage, and severe cases will easily cause fractures.
There was a screenshot of the group chat of "Snow Season Dry Staring and Recuperating Injury Group" circulated on the Internet, and behind the names of each member, one or more injured parts that looked very painful were marked, and some netizens carefully summarized and made a map of everyone's fracture distribution map, which was very shocking.
"Indeed, there are not a few injured people who go to the hospital's emergency orthopedic department for treatment because of skiing every winter. Whether you are a beginner or an experienced skier, it is possible to break a bone in skiing. Zhao Bin, chief physician of the emergency department of Beijing Jishuitan Hospital, said.
However, there is no need to worry too much, most falls are basically soft tissue injuries, sprains and strains, and fractures are relatively rare. In the event of an accidental fall, skiers need to make a preliminary judgment about their own situation. In this regard, Zhao Bin shared the method of preliminary identification: "Fractures, especially limb fractures, can cause severe pain, and even heart-rending pain can occur when you move a little. If possible, the injury can be viewed in a safe place, and the fracture site is often visibly swollen or even deformed. ”
Once the fracture is confirmed, try not to move the injured limb as much as possible and call for help as soon as possible. "While you wait, check for open wounds with the help of a companion or if your condition allows. Those who have conditions can be disinfected with wound disinfectants, and those who are unconditional can use purified water to remove dirt and small foreign bodies from the wound and its surroundings as soon as possible, and bandage it with clean gauze to avoid infection. Zhao Bin reminded.
After the rescuers arrive, they will first assess whether the injured person is in danger of life, and if the limb is fractured, they will generally use elastic bandages and wooden boards to simply fix the fractured limb to avoid secondary injury, and then send the injured to the hospital for treatment.
It is true that fractures can have varying degrees of impact on people's work, life and health. In order to reduce the possibility of fractures, Zhao Bin said that before exercising, especially before skiing and other strenuous exercises, it is important to warm up accordingly. Because during exercise, the load on muscles and ligaments will be greater than when they were relatively stationary before, and if the amount of exercise is too large or the movement is uncoordinated, it is easy to cause strains.
Therefore, before skiing, it is necessary to stretch the arms, thighs, calves, and buttocks that are stressed during the exercise. At the same time, the warm-up will also stimulate the local blood circulation, cardiovascular and respiratory systems of the whole body. When people get into skiing, the previous warm-up can give skiers better muscle coordination, not falling too hard, and the chance of fractures will be relatively reduced.
Why did skiing happen?
What are the risks of snow blindness?
In sunny weather, we often feel that the sunlight is very dazzling, but after the reflection from the ground, buildings and other objects, it generally does not cause harm to the eyes. However, on the highly reflective snow made up of countless ice crystals, and there are no buildings around it, the sunlight reflectivity is greatly improved, and skiers who ski on the slopes for a long time can basically look directly at the sun. Snow blindness is known as snow blindness due to excessive ultraviolet rays, redness and swelling of the eyelids, eye pain, photophobia, tearing, inability to open the eyes, and blurred vision.
In order to avoid snow blindness, Zhao Bin reminded everyone: when skiing in sunny weather, you need to wear special protective glasses, and those who have conditions can wear hats and masks to keep warm and shade the light. At the same time, you can choose to glide in a relatively shady place. During skiing, it is necessary to pay more attention to rest, and find a backlit place to rest every time you ski for a period of time to avoid the continuous exposure of your eyes to a large amount of ultraviolet rays for a long time.
What exactly is deadly "powder snow"?
Some time ago, the news of "Chinese tourists suffocated from inhaling powder snow while skiing in Japan" was widely concerned, which also made everyone curious about powder snow.
▲Kagura Ski Resort in Japan
In fact, powder snow is a very soft and dry, floury snow that is more common in cold, dry regions. The powder snow is soft and does not hurt even if you fall, so it is loved by many skiers. However, for beginners or non-professional skaters, the powder snow is so deep that the head of the skateboard may fall into the snow after falling, making it difficult to get up on its own without the help of others. If you accidentally fall your entire face into the snow, it is easy to inhalation suffocation, which can be life-threatening.
In order to avoid the fear of life, Zhao Bin suggested that beginners and amateurs should check the relevant introduction in advance when choosing a ski resort, try to avoid rashly trying powder snow resorts when the technique is not proficient, and do what they can when doing outdoor sports.
From a risk perspective,
How to choose a beginner's snowboard and a skier?
Whether it's skiing at breakneck speed or snowboarding with brilliant skills, beginners will be the envy of beginners. However, from the standpoint of their own safety, skis may be relatively more suitable for beginners.
"On the one hand, the double board has a larger area in contact with the ground, which can provide better adhesion between the human body and the ground, and the stability is better than that of the veneer. On the other hand, skis, which can be steered and speed controlled with the help of a cane, are easier to balance than snowboards, which require a strong core and skill. Stability and balance are prerequisites for avoiding falls in skiing, and the risk of injury is reduced. Zhao Bin explained the reasons why beginners are more suitable for skiing.
▲ Skiing
▲ Snowboarding
People often say that to learn to ski, you must first learn to fall,
Is that really the case?
It's often said that "no fall is no skiing", and it's true that almost no one can completely avoid falling in skiing, whether it's a beginner or an expert in the snow. Therefore, it is crucial to learn to fall in a way that protects yourself.
▲It is very easy to fall while skiing
Taking skis as an example, Zhao Bin said: "For beginners, the speed is generally not too fast, so you often feel that you are about to lose control or fall, and you need to quickly separate your feet outward. Try to reduce the risk of upper limb fractures by keeping the thick buttocks on the ground first, with your hands at your sides or crossed over your chest, and avoiding using your hands to push the ground hard. ”
It is true that during the practice phase before learning to fall, it is also important to equip all parts of the body with protective gear, and do not let off the protection of the body because you have not officially slid on the ramp.
The "little turtle" that sprouted out of the circle
Can it be used as a "fall prevention weapon"?
On the lively snow field, you can often see colorful "little turtles" worn by "ski newcomers", and it is loved by many people. But can it really act as a "fall prevention weapon"?
In this regard, Zhao Bin said: "This kind of 'little turtle' is more suitable for beginners, because their gliding speed is generally not very fast, and the impact is not too large, while the soft 'little turtle' can play a certain cushioning role and can better protect the skier's buttocks when falling." But for professional skiers who often gallop on advanced tracks, it is best to choose professional hip protectors as protective gear. ”
Cold winter
Snow always has a lot of charm
Attract us to conquer and gallop
But before the chic and wanton enjoyment
It is also necessary to have a clear understanding of one's own situation
Zhao Bin reminded everyone
Skiing is a great winter outdoor sport
But beware
It should be avoided after fatigue, cold, full food, and alcohol
Get involved in the sport
Pay more attention
Helmets, goggles, gloves, knee pads, elbow pads, hip pads, etc
Wearing snow gear
It is necessary to enjoy the joy of snow sports
You should also pay attention to your own health and safety
The balance of the holiday remains
