Ready to climb the mountain during the holiday? You need to make these preparations before climbing.The mountain scenery is beautiful, and you will be addicted to climbing once, but before climbing the mountain, learn 7 things to save your life.1. Really do a high degree of adaptationIn the high mountains above 2500 meters above sea level, due to the thin air and reduced atmospheric pressure, the amount of oxygen available to the human body is insufficient, which will cause physical discomfort. This is mountain sickness.Acute Mountain Sickness (Acute Mountain Sickness, AMS) is the most common disease when climbing a mountain. The incidence is as high as 36%. Patients will have headaches, dizziness, nausea and vomiting, loss of appetite, fatigue, weakness, and difficulty sleeping. In addition, 0.5 to 1% of people may have high-altitude cerebral edema (unsteady walking, changes in consciousness or mental state) or high-altitude pulmonary edema (lips and nose are not bloody, wheezing, breathing difficulties, chest tightness) , Hemoptysis, rapid heartbeat and breathing), all can be fatal.There are only two ways to prevent mountain sickness. One is to take medicine to prevent it, and the other is to properly arrange the climbing itinerary to make a high degree of adaptation.Rapid ascent, the destination is too high (especially the height of sleep when staying at night), and the history of mountain sickness will increase the chance of mountain sickness. People who have experienced high-altitude pulmonary edema should not take medication before going up the mountain. , The chance of recurrence is as high as 60%, and a cold or upper respiratory tract infection before going up the mountain will also increase the chance of high-altitude pulmonary edema.If you don\u2019t want to take medicine and have plenty of climbing time, you can slow down your ascent, spend the night in a mid-altitude area first, drink plenty of water and avoid alcohol, so you can slowly adapt to the altitude.It is best to control the climbing height of 600 to 800 meters every day when climbing. As long as you adapt to the height, you can reduce the chance of mountain sickness.2. Carry raincoats and warm clothing with youMany people know that severe mountain sickness can be fatal, but ignore the terrible temperature loss.Wearing the wrong clothes to go up the mountain is very dangerous. When climbing, you must pierce through the air-perspiration functional clothing. If the inner layer is wearing cotton clothing, the outer layer is just a general windproof jacket, and the moisture can't get out. It is easy to lose temperature. If your clothes are wet, you must change to spare clothes as soon as possible. It will be colder if you continue to wear wet clothes.How dangerous is hypothermia? When the body temperature drops to 35 degrees Celsius, there will be severe tremors, but the consciousness is still clear; once the temperature drops to 32 degrees, the consciousness will be blurred, the trembling will cease, and the body will gradually die.In order to avoid loss of temperature, even if you just pack lightly, you should carry the following items in your backpack: raincoat, spare warm clothing (wrapped in double plastic bags for waterproofing), headlights or flashlights, food, and water. Some people think that bringing raincoats and spare clothing is heavy, but these are magic weapons to prevent loss of temperature. It is very likely that they will not be used after climbing the mountain ten times, but as long as they are used once, they will save your life.3. Patients with chronic diseases should consult a doctor and adjust medication before climbingWith the consent of the doctor and adequate preparation, patients with chronic diseases can climb mountains. For example, people with mild high blood pressure who have been well controlled in recent months, patients with stable and mild heart failure can climb mountains (but there may still be sudden severe arrhythmia), and those with moderate, severe or unstable heart should be avoided.Once in the mountains, a mountain friend installed 6 heart stents. The risk is very high, like gambling! Hypoxia, low temperature and work will increase the risk of angina pectoris. If you use nitroglycerin regularly on flat ground, it is not recommended to climb the mountain because the thin oxygen on the mountain will increase the burden on the heart, angina and hypoxia. The situation will be more serious, and even sudden death may occur.Patients with chronic diseases must carry medicines when climbing mountains. It is very difficult to get medical treatment on the mountain. Once they feel uncomfortable, they should quickly dispose of and take medicine while the symptoms are still mild to relieve the symptoms.4. Walk slowly and do not drink too much water during the journeyCramps don't necessarily mean you haven't warmed up. Taking too many steps and drinking too much water can also make you cramps. Small steps and steady walks are more important than striding and walking fast. Inexperienced climbers often rely on good physical strength at the beginning, striding uphill and walking quickly, which is not only easy to get tired, but also easy to cramp. I usually walk slowly, but I can walk for more than 10 hours.You may wish to take exercise food during a short break and replenish calories at any time. If you wait until you are hungry, you will not be able to recover your strength in time. However, you should pay attention to the intake of water. It is not advisable to drink too much water during the journey, because you sweat a lot. Drinking water can easily cause cramps due to electrolyte imbalance in the body.Drinking plenty of water can help prevent mountain sickness, but drinking too much water during travel can easily cause cramps, so you need to adjust the timing of drinking water. Generally, you need to drink about 2 to 3 liters of water a day when you are climbing, and you can drink 700~ before departure in the morning. 800ml, drink less during the journey, wait for a big break or arrive at the camp, and then slowly drink enough water.5. Practice squats, jogging, and physical fitness before climbingOne or two months before climbing the mountain, it's time to start exercising. Nick said that the muscles used in mountain climbing tend to focus on the thighs and calves. It is recommended to practice squats and train the thigh muscles so that the knees will not be hurt when going downhill. You also need to train your lung capacity by jogging, at least to train. Can easily run 3 kilometers.If your knees are not good, you can wear knee pads and use two trekking poles when climbing, which can slightly reduce the pressure on your knees and avoid cramps.People who have the habit of running and other sports may not be more popular when climbing mountains, because the muscle endurance required when climbing is stronger than when running on flat ground. Therefore, in addition to squatting and jogging, climbing stairs (going downstairs to take the elevator) and climbing the suburbs are also good muscle endurance training.Step by step and adjust your physical fitness well, you will not be very tired and panty when climbing, and you will have enough time to appreciate the scenery along the way. You can only enjoy the beauty of the mountains by exercising your physical fitness. After climbing, you want to climb another mountain.6. Walk with your teammates, don\u2019t climb aloneClimbing alone has a high probability of mountain disasters. 70-80% of mountain disasters occur in the case of solo climbing. Therefore, it is very important to go together when climbing.When climbing the mountain, as long as the line is too long, people may get lost, especially if the weather is bad and the clouds are thick when going down the mountain, it is easy to get a fork in the road if you are not careful.7. The flight mode of the mobile phone is more power-savingThe mobile phone signal on the mountain is not as good as on the flat ground, and sometimes the cloud and fog can make the signal unstable. If you encounter a critical situation, the safest thing is to bring your own mobile phone (check the channel used by the mobile phone in advance) and satellite phone.If the mobile phone has no signal from time to time, it is better to change the text message than to make a call, because the mobile phone can send the text message as soon as it catches the signal.In the mountains, the temperature is low, and the battery consumes fast. At this time, turn the phone into airplane mode or turn off the phone, and the battery can last longer. If the phone is in flight mode, the battery can last for 3 days, if it is in normal mode, the battery will run out in 1 day.
