Recently, a photo of a teenager with frostbite in Tonghua, Jilin Province has attracted widespread attention on social media.
The photos show that the girl's hands are severely frostbitten, which is shocking.
All this is because she runs outdoors in minus 18 degrees Celsius without any cold protection. Her hands were nearly amputated.
The risky decision almost made a big mistake
In the cold and biting winter, Xu's adventure was shocking.
In the extreme cold of minus 18 degrees, she desperately tried a gloveless running session.
At first, no one expected the consequences to be so severe.
During the training, Xu felt that his hands gradually lost strength, his complexion turned white, and the pain became more and more intense.
When the coach and classmates noticed this, they immediately tried to relieve the pain by rubbing each other's hands, but to no avail.
Eventually, Xu, who was sent to the hospital in the emergency room, was diagnosed with severe frostbite, which was caused by prolonged exposure to cold air. If she had been sent to the hospital later, she could have been at risk of having her leg amputated.
This rash decision almost made her lose her hands.
Face, hands, feet: areas with a high incidence of frostbite
Our parts of the body are not equally resistant to cold.
In particular, the face, hands, and feet are more susceptible to cold due to poor blood circulation.
In extreme cold environments, without proper cold protection, these areas are likely to feel cold pain first, or even lead to frostbite.
Mr. Sun, a running enthusiast in Harbin, is a case in point.
He exercised outdoors for a long time in an environment of minus 30 degrees Celsius and did not take warm measures, and as a result, he also developed frostbite symptoms on his face, and was diagnosed with frostbite II degree II area of the face.
These events are a reminder that we must pay attention to cold and warmth when exercising outdoors in winter, whether it is on the face, hands or feet, it should not be taken lightly, otherwise it can lead to serious consequences.
Caution should be exercised outdoors in winter
The case of frostbite underscores the seriousness of outdoor sports in winter. From a sports medicine perspective, extreme cold environments have multiple effects on the human body:
1. Imbalance in body temperature regulation
2. Effects of muscles and joints
3. Circulatory system adjustment
4. Challenges of the respiratory system
5. Protection of skin and soft tissues
In addition to this, keeping clothes dry is extremely important, especially for sneakers and socks.
A cold and humid environment not only leads to reduced comfort, but also exacerbates heat loss and increases the risk of frostbite and other cold-related injuries.
Choosing proper footwear and socks that are waterproof and breathable, as well as changing wet clothes in a timely manner, are essential to keep your body dry and warm during extreme weather.
The "Three-Tiered Principle" of Outdoor Training
When exercising outdoors in cold weather, especially when running, it is advisable to follow the "three-tier rule" to provide optimal warmth and flexibility.
This principle is not only based on the physical properties of the garment material, but also incorporates the knowledge of sports medicine to ensure the safety and comfort of athletes in cold environments.
First layer: Quick-drying perspiration layer
The quick-drying perspiration layer adheres to the skin, and the main purpose is to wick away sweat generated during exercise and keep the skin dry.
This layer is usually made of a quick-drying, breathable synthetic material, such as polyester, which is able to quickly transfer sweat to the outer layer, reducing the cooling effect of the skin in cold environments.
From a sports medicine perspective, keeping your skin dry can help reduce the rate at which your skin cools, reducing body heat loss, while preventing muscle stiffness and excessive drop in body temperature caused by cold sweat.
2nd layer: thermal layer
The insulating layer is located outside the quick-drying layer, and its main function is to provide the body with the necessary warmth.
This layer is usually made of down or high-quality synthetic fiber filler materials, which are lightweight and have good thermal insulation properties, forming an insulating air layer without adding too much weight and volume.
Sports medicine research has shown that proper warmth can maintain muscle temperature and reduce the risk of sports injuries, while helping to maintain the body's core temperature and ensure the proper function of major organs such as the heart and lungs.
The third layer: windproof and thermal insulation
Wind insulation is the outermost layer and is primarily responsible for protecting against cold air and bad weather.
This layer of clothing should be made of windproof and waterproof materials, such as synthetic fibers with a windproof film, which can not only block the cold wind but also prevent rain and snow from penetrating.
Sports medicine emphasizes that windproof insulation is essential for maintaining body temperature, especially in windy environments, as wind can quickly take away heat from the body, increasing the risk in cold environments.
At the same time, the breathability of this layer is also important to ensure that the heat and moisture expelled from the body can escape, prevent sweat from condensing inside the garment, and keep the body dry and warm.
By adopting this "three-tier principle", athletes can maintain a suitable body temperature in cold environments, reduce the risk of frostbite, and ensure sufficient flexibility and comfort for movement.
This dressing strategy is key to keeping you warm during outdoor sports, especially during long periods of time or high-intensity outdoor exercise.
The outdoors is fascinating, but safety is always a top priority.
In winter, it is especially necessary to pay attention to the cold and keep warm, so as not to bring heavy costs to impulsiveness and negligence.
We should advocate healthy and safe ways to exercise and enjoy the joy of life, rather than letting sports become a source of regret and injury.
