Summer outdoor climbing precautions --- drinking water Summer sports are sweaty and must be replenished in a timely manner. However, if the drinking water is not in the right direction, it will cause adverse consequences. Many models in beverage advertisements tend to pick up a bottle of beverage and drink when they are in exercise or during a break. They seem to be thirsty. In fact, from the exercise physiology point of view, it is very harmful. Drinking lots of water during and after exercise will give rise to the blood circulation system and digestive system, especially to the heart, causing more fatigue. The result of drinking lots of water is only sweating more, leading to further loss of salt, causing cramps and cramps. Response measures: A small number of times, drinking only a few drinks each time, the frequency of drinking water frequently, do not rely on thirsty feeling as a basis for additional water, when not thirsty but also to add water, so that water is added in a balanced manner. Do not drink plenty of water at a time, but do not control supplemental water. If water is lost in a large amount, it will not be supplemented and will cause severe renal failure. In general, one day of summer activity (5-8 hours) requires at least 2-3 liters of drinking water and even 6 litres of water at high temperatures. Summer outdoor climbing precautions --- fever (heat failure, heat stroke) In summer, when you participate in outdoor sports, because of the high temperature and the large amount of exercise, the amount of heat accumulated in the body is more than that emitted.

Response measures: In order to protect the sun from the event and prevent the body from being thatch, thorns and strains, marching in the need to wear a hat, wear long trousers, but this brings the problem of heat. To help spread body temperature, when you walk in the sun, you can soak your hat with water; when you walk in places where the sun cannot reach, remove the hat; when you rest, try to put the backpack down and unbutton the top collar buttons; The best place to rest is in areas where the sun does not reach and where it is ventilated.

Severe patients with heat stroke, unless the recovery is very good, it is recommended to find someone to accompany the patient out of activities. Summer outdoor mountaineering precautions - hot cold In summer, when the body is moving at high temperatures, the body produces heat quickly, and the skin's capillaries expand in large numbers to facilitate body heat dissipation. If excessive cold stimulation is encountered, the pores on the body surface that have been opened will suddenly close. This will result in dysfunction of the internal organs of the body, abnormal regulation of the body temperature of the brain, and illness. Usually, a "cold cold" occurs, which is also known as a cold in the summer and may even lead to more critical illness. Response measures: In the summer when you march, if you have sweating, if you have mountain springs, streams, ponds, etc., or you are passing by the sea, you must not cope with a cool moment and jump immediately to take a cold shower. Even if the activity is over, after reaching the destination, wait for the body temperature to drop and then take a cold shower. After the event is over, if the returning vehicle is an air-conditioned vehicle or in an air-conditioned room, it must not be turned on and directly blows into the body.

Summer outdoor climbing precautions --- cold drinks It is a pleasure to enjoy outdoor drinks in the summer when you have iced drinks.

Response measures: A small amount of cold drinks is good for cooling, but it should not be excessive. It should be treated according to specific conditions. The frozen drinks that we brought before we set off should be consumed in small quantities. After the event is over, do not drink frozen beverages or beer until after the body temperature drops sharply. Summer outdoor climbing precautions---clothes In summer, a lot of sweating happens in the outdoor sports. Soon the clothes get soaked. Many people often let the clothes wet when they arrive at the destination, trying to dry the clothes by their own body temperature. This is extremely harmful, and in the long run it will cause rheumatism or arthritis. Response: Before attending the event, bring a set of ready-to-wear dry clothes (especially the tops) and a coat to the backpack. Immediately after the destination, change the wet clothes. During the break in the middle of the event, if there is a lot of wind, if the rest time is long, you must put on the jacket in time, otherwise the wind will take away a lot of body heat, and the human body will alternate between cold and hot, and it is easy to cause illness. In order to facilitate the volatilization and heat dissipation of sweat, it is advisable to buy quick-drying garments made of chemical fiber as the outer clothing. The best is quick-drying and anti-ultraviolet ray clothes. The trouser legs are best to be removed.
