The climate in mountainous areas is often changeable. One second, the sun is shining. The next second, the wind and rain will make you fall into the ice room. Clothes soaked by rain will take away your heat, and cold air will aggravate your heat loss, which is prone to temperature loss. The key to prevent temperature loss is equipment. Follow? Wear layered clothes? Principle: change clothes frequently during the journey, put on and take off quickly, and refuse laziness. It is easier to add clothes when it is cold, and humidity will accelerate the conduction and evaporation of human heat to the outside world. At the same time, we should also pay attention to wind protection. Convective heat dissipation is the main cause of body heat loss, and attention should also be paid to the insulation of the exposed parts of the head and hands.
The way to cope with hypothermia is to wrap a life-saving blanket around the trunk and encourage slight shaking to restore body temperature. However, don't do strenuous exercise any more, and quickly supplement sugar to help the body generate heat. In case of severe temperature loss, please wrap the whole body with life-saving blanket or plastic sheet, then wrap the insulation layer and waterproof layer, and seek help for medical treatment immediately. Keep at least 100 calories at any time. These calories come from sugar, such as energy glue, or the same amount of honey as a first aid for mild hypothermia.
We all know the harm caused by altitude sickness. Keep your mood calm and relaxed, and don't let your heart beat faster, so as not to accelerate the occurrence of hypoxia. No matter what tools you take to the local area, don't exercise at once. Take a rest first and let yourself adapt to the environment slowly. It usually takes hours or days to get used to the environment here. You can buy some drugs to relieve hypoxia according to your own situation. Lack of oxygen is still very harmful to us. If the symptoms of hypoxia cannot be alleviated, oxygen therapy should be given in time. If possible, take the patient to a low altitude area. In terms of diet, we should choose some foods that are easy to absorb and high in vitamins, because foods that are not easy to digest will easily increase the workload of our stomach, increase the burden on our heart and aggravate altitude sickness. You can also bring chocolate or sugar, which can alleviate the effect of hypoxia.
