What is this dreaded hypothermia all about? Why does it happen in the summer? The first thing you need to do is to get your hands on a new pair of shoes or boots, and you'll be able to get them to fit in your pocket.
What is hypothermia?
Liu Gang:
These are a relatively common physiological phenomenon, generally speaking, the human body heat loss is greater than the heat supply, resulting in the human body's core temperature decrease, and finally produce a series of chills, confusion, cardiorespiratory failure and other symptoms, and ultimately cause the death of the disease.
The core of the human body mainly refers to the brain and trunk of the heart, lungs and other major organs used to maintain life, is relative to the human body limbs and surface skin.
The hypothermia is categorized as mild, moderate and severe.
Mild hypothermia, which is characterized by uncontrollable shivering, inability to perform complex movements, but the ability to walk and talk. When participating in a marathon, such as complex terrain, climbing on mountains, more demanding physical conditions, if in this case a mild hypothermia, it may cause deformation of movements, fall off a cliff or tripped over a stone, fall into a deep pit.
Moderate hypothermia, which is characterized by confusion and loss of motor coordination, especially in the hands, such as the inability to zipper. The sunscreen or windbreaker that you may be wearing during a run, if you have moderate hypothermia and you can't zipper it up, then the temperature loss is going to be much more rapid, and it's very dangerous. The reason for this is insufficient blood flow to the periphery. Slurred speech, violent shaking, erratic behavior, e.g., starting to undress but not feeling cold yourself. There will be intense shaking, muscular incoordination begins to be evident, such as inconsistency between arms and legs, talking head responds quickly but the mouth can't keep up, movements are slow and seem labored, the feet begin to stumble, and confusion begins to set in.
In severe hypothermia, there is a persistent, violent shaking, it is more difficult to speak, thinking is slow, forgetfulness begins to be evident, obvious decline in mobility, not able to use your hands, walking often tripping, more depressed, intermittent shivering, the skin outside will be bluish-purple and swollen, and the system is very poorly coordinated, and even the road can not be walked, thinking is also more confused. can't walk, and thinking is more confused and nonsense. But it is also possible to remain in one position and seem to show signs of wakefulness.
For the definition of temperature, mild hypothermia, where the core area is the heart, lungs, etc., is around 37 degrees to 35.5 degrees, moderate hypothermia is around 35 to 33 degrees, and severe hypothermia is between 33 degrees and 30 degrees.
Why is it possible to get hypothermia in the summer?
Liu Gang: Every 100 meters above sea level, the temperature will drop 0.6 degrees, first of all, Gansu Yellow River Stone Forest scenic area average elevation of about more than 2,000 meters or so, Gansu temperature is not too high, if you catch this regional temperature plummet, may be a moment instantly to 0 degrees.
In addition, as in the case of pyrexia, pyrexia does not necessarily occur in the summer, and does not necessarily occur outdoors. Sometimes when you wear thicker clothes and the heat doesn't get out, whether it's in the winter, summer, or fall, it's easy to get heat stroke.
Hypothermia, which is when the body loses more heat than it gains, is not absolutely related to temperature, so even in summer, hypothermia can occur.
How do you help yourself when you're out in the cold and you're alone?
Liu Gang: It is imperative that the first time, in the case of the body can control, the first time should call for help.
Rescue came on the road can not be idle, first look at their own equipment to carry, if anything, should be quickly to a wind, or the temperature is relatively warmer point of the place, at least to leave the original territory, resulting in loss of warmth shows that the climate of the place is certainly not right, to avoid the original site, quickly to a relatively windy, or even no wind, such as the triangular The most important thing is to avoid the original site, and quickly go to a relatively windy or even windless place, such as a triangle, a sheltered harbor, a cave, or the back of a windy hill, a low-lying area, etc., to avoid the loss of body temperature to the maximum extent.
When choosing a place to hide, you have to explore it well, and you can't choose a place that is prone to landslides, mudslides, or floods, or a place that is struck by lightning.
In addition to moving limbs, can not stand still, but not strenuous exercise, slowly moving hands and feet, pinch and knead, the action from small to large, slowly feel the body heat, slowly feel the phenomenon of heat loss gradually disappeared, and even appear normal, slowly comfortable situation.
As soon as the medical institution arrives, it is just about time for you to recover and better cooperate with the medical team to carry out in-depth treatment.
How do I help someone who is suffering from hypothermia?
Liu Gang: The first thing the witnesses need to do is to call with the professional medical institutions, we must find a person to help us find professional medical institutions to come over to save him, and then in the process of the medical institutions rushed to the scene of the incident, we have to transfer this person to a safer and more secure place to the next! The next step is to help him rub his palms, talk to him, divert his attention, if there is food or hot water to supply, and then get the clothes over to him to cover a cover, similar to such as the ability to do these things.
After the medical professional medical institutions came, then the handover, the medical institutions to the road process, the first witness and the survivor of all the things that happened between, including his signs of change, the process of doing something, dictated or written down to others to see, with him to understand the process of what happened, as the final hospital depth of treatment or follow-up treatment of a valuable reference material. The first step in the process is to make sure that the patient has a good understanding of what is going on in the process.
My partner and I are both experiencing hypothermia.
Liu Gang: Rescue, the United Nations common a concept called "to save others, first protect yourself", your own original can not, you not only can not help, may also help, and also to take themselves into, it is not worth it. So first of all, you have to make sure that you are safe, so you can save another person.
If you and your companions can support each other, then you help me to help you, who is conscious of who first came to get in touch with the medical institutions call, they are the last to save you. And companions should hand over to each other, encourage each other, support each other, maximize their life survival time, can not do nothing.
In the end, NetEase Health would like to remind everyone that when participating in extreme sports or tournaments, challenging oneself and pursuing breakthroughs is certainly a commendable spirit, but we must fear nature, respect science, and cherish life, and fully recognize the risk of extreme sports, fully understand our own physical conditions, and fully learn the knowledge of first aid and self-rescue, and do our best to be prepared for the worst before each departure. The most important thing is to be prepared for the event, so that you can better enjoy the competition and enjoy life.
