Is it snowing over there in your house?
In mid-January, the first heavy snow of 2022 went live, affecting more than 25 provinces.

Snowy days, step by step!

If you are not careful, you will rub, rub, rub on the smooth ground.
Drifting into storage is no longer a dream.
Heavy snow has put a silver coat on the world, but it has also brought a test to everyone's travel and health.
The ground is slippery after the snow, which brings a lot of danger to travel.
An investigation by Beijing Jishuitan Hospital found that among the patients who fell after the snow, the oldest was 91 years old and the youngest was only 4 years old.
The most vulnerable areas are the wrist joint, ankle joint, shoulder joint, calf, knee joint, and elbow joint [1].

If you are traveling by car, you should be more careful.
The risk of fatal traffic accidents caused by snow days decreased by 7%, but the number of non-fatal accidents increased by 23%, and the number of collisions that only caused property damage increased by 45%[2].
In simple terms, driving on snow days is more likely to occur small scratches. Even if there is no danger to life, it is quite disturbing.
So what to do? Can't you go out on a snowy day?
Even if I agreed, the boss wouldn't agree!
Don't worry! Put away the following "Snow Day Anti-slip Treasure Book" to make your travel stable.
1. Change into a pair of non-slip shoes
You can refer to the 3 standards of the sole material, softness and hardness, and texture to see if your shoes are non-slip.
Material: rubber bottom is selected
Other common sole materials include beef tendon soles, plastic soles, foam soles, etc., which are not as non-slip as rubber soles.
Softness: Choose soft
Soft soles increase the contact area with the ground, thereby increasing friction and making them more non-slip.
Grain: Choose both horizontal and vertical stripes
The sole of the longitudinal pattern has a large coefficient of friction on the smooth ground; the horizontal pattern has a large coefficient of friction on the rough ground. Therefore, on snow days, it is best to choose a sole with both horizontal and vertical patterns, such as wavy patterns, herringbone patterns, polyline patterns, etc.
Don't forget one thing: don't wear high heels or muffin shoes!
Their contact area with the ground is small, the sole material is harder, the grain is relatively thin, and they simply step on all the minefields.
(Don't wear it like that!) ）
2. Learn to walk with penguins
If you want to talk about ice walking experts, it must be penguins.
The penguin's walking posture is the most difficult to fall-
Leaning forward, with eight figures on the outside of his feet, taking small steps[3]...
(Left: Usually walk with alternate legs to support the body.) But walking on the ice in this way, each leg and the angle of the ice surface are not vertical, it is easy to fall. Right: Walk on ice and let the center of gravity fall on the leg in front of you. Source: References[3])
The action essentials are:
1. Lean forward and try to put the center of gravity on the leg in front of you, perpendicular to the ground.
2. Feet are the same width as the shoulders, arms are placed on both sides of the body, slightly bent knees, feet outside the figure of eight, with a swinging small step forward.
3. The most important point - go slowly!
(Penguins, go fast and fall.) Source: soogif)
Remember one more thing: don't stick your hands in your pockets!
Exposed hands on the outside to maintain balance. In case of accidental fall, you can also hold on in time to avoid falling on the more important head, neck, etc.
3. Find the right place to get off your feet
Walk on the snow and step on the soft snow.
Don't step on a compacted "snow shell"!
Also, don't walk on blind alleys, tiles, or on roads that are repeatedly crushed by vehicles.
When passing through alleys or shades, be more careful to watch the road.
(Take such a path, don't slow down)
(If you don't drive, you can directly pull down to the fourth part and see The Correct Fall Posture Tutorial" by Diange)
1. Before you go, remove the snow and ice from your windows
There is ice or snow on the front windshield, do not open the wiper to blow snow, and do not use hot water to de-icing.
You can start the engine first and blow it with the air conditioner for a while. Wait for the ice and snow to melt a little, and then use the ice and snow shovel for car glass to slowly remove the ice from the ice cracks.
The ice and snow covered by the roof should also be cleaned up, so as not to fly down and affect the line of sight when driving.
2. When driving, there is one word - stable!
When driving in snow, don't hit the steering wheel, accelerate sharply or brake sharply.
Before braking, tap the brakes a few times to remind the rear car to slow down to avoid rear-end collisions.
3. Don't be nervous about the vehicle slipping, remember one thing
In case of side slip or tail flicking, don't panic! The first thing to do is to close the throttle lightly and then slightly back to the steering wheel, constantly making small adjustments between steering and returning to positive.
After the vehicle returns to the right, then gently press the brakes until the body is completely stable.
If possible, it is best to add tire snow chains.
(This is mostly the result of the brakes being slammed straight to the end.) Source: soogif)
No kidding! "Falling" minimizes damage to the body [1].
1. When side slip occurs, let the body fall to the ground and try not to use your wrist to support the ground.
Winter cotton coats are relatively thick and are not prone to serious damage. But if you hold the ground with your hands, it is easy to cause a broken wrist.
2. When slipping backwards, squat or curl up in time and cover the head with your hands.
3. When slipping sharply and violently (such as slipping on a slope), try to hold your head and neck tightly with both arms to avoid hurting the cervical spine or head.

If you subconsciously support the ground with the palm of your hand, there are symptoms such as swelling and pain in the wrist joint, and the pain when you clench a fist, you should use the uninjured hand to support the injured hand and immediately go to the hospital to see the emergency department.
If you fall on your leg or ankle, it's best not to hold on and continue walking, but to dial 120 in the same place, or seek help from passers-by to the emergency department or orthopedic department.

It will definitely help more people
