Question: I feel dizzy when I am climbing. Is it a heat stroke? A: There are several kinds of discomforts and diseases caused by high temperatures. In the wild, we can identify and treat them based on body temperature and consciousness.

In the summer, the rate of declining altitude is decreasing by approximately 0.6 degrees for every 100 meters. When the temperature in the flat area exceeds 36 degrees, the temperature in the mountain area below 1,000 meters above sea level will reach 30 degrees or more. The risk of fever is still not to be overlooked when it comes to other risk factors, such as old age and chronic diseases. 
Classification and characteristics of fever The discomfort and illness caused by high temperatures, called fever, are also called thermal injuries. The classification and name of fever can often be confusing and there is no clear line between different disease names. In fact, in the wild we do not need to make the correct diagnosis. According to the central body temperature below 38 degrees or higher, it is divided into two groups. The former can be disposed on the hill first, and the latter must be sent to the hospital urgently. For central body temperature measurements, an anal thermometer or a calibrated ear thermometer can be used.
A. Central body temperature below 38 degrees, a clear consciousness 
Hot cramps
The patient's perspiration function is normal, but due to excessive sweating in order to disperse a lot of heat, or simply adding water without salt, the imbalance of electrolytes in body fluids (mainly hyponatremia) causes muscle cramps (cramps) Phenomenon, called hot cramps. The patient's muscles may cramp and may feel weak, but the awareness is clear that the center temperature is normal or slightly elevated.
Heat syncope
The syncope that occurs when standing for a long time (such as military training) in a hot environment. The patient's central body temperature is normal or slightly elevated, so it is not heat stroke. May be due to excessive sweating, resulting in thick blood and low blood volume, coupled with long standing, so that the return of blood confined to the lower limbs, resulting in inadequate blood flow to the brain, resulting in syncope phenomenon. Patients may experience dark eyes or transient loss of consciousness, but they will soon return to consciousness after lying down and moving to a cool place.
Although the pathological changes of enthusiasm and fever syncope do not include body temperature regulation disorders, because they are similar to the environmental factors that promote heat stroke, they should remain alert and properly disposed of to prevent heat stroke from occurring.
2. Central body temperature above 38 degrees, disturbance of consciousness 
Heat exhaustion and heatstroke
Many people think that the skin of patients with heat exhaustion is clammy, while the skin of patients with heat stroke is dry heat, which is an arbitrary and dangerous classification.
In fact, these two terms represent different stages of the same course. The human body overheats (or poorly distributes heat) in the hot environment and causes sweating. Eventually, due to the overload of body temperature-regulating central compensatory mechanisms, the body temperature rises rapidly, causing multiple organ failure and death;
Heat exhaustion and heat stroke represent earlier and later changes in the course of the disease.
However, there is no clear demarcation between the two. Patients with wet or cold skin may have body temperatures as high as 40 degrees Celsius or higher. Conversely, although the perspiration function of patients with heat stroke may be hampered, it is because of previous massive sweating. The body surface may not be dry either.
The vigilance of the possible fever environment and the early recognition and treatment of possible symptoms are much more important than the differential diagnosis of fever. Early symptoms include fatigue, weakness, headache, confusion or hallucinations, gait instability and loss of sense of direction. Sometimes there are convulsion phenomena, followed by coma and death. For the patient to do a physical examination, often found: low blood pressure, rapid pulse and breathing, the central body temperature increased (usually higher than 40 degrees) and so on.
If the center body temperature exceeds 41 degrees, the mortality rate is very high.
Question: If you do not carry a thermometer with you, how can you confirm that there is no heat stroke?
A: If you do not have a measurement tool, you can touch the patient's skin with your hands. If you are very hot, you may be suffering from heat stroke. However, if you are not hot, you cannot rule out the possibility of heat stroke. If there is a disturbance of consciousness, it must be treated as severe. 
The first step in the diagnosis and treatment of heat stroke and other fevers, initial response:
As long as someone is unwell in a hot environment, central body temperature should be measured. Consciousness is also an important criterion for judgment. If the central body temperature is lower than 38 degrees and the consciousness is clear, drink cold water immediately and look for shade and rest. If the patient’s central body temperature is higher than 38 degrees or the consciousness is unclear or the vital signs are unstable, Immediately seek help from outside and begin to prepare for first aid and reduce body temperature.
The second step, lower body temperature:
Move the patient to a cool, well-ventilated place. If there is a stream or lake on the side, immediately soak the patient in cold water; if not, use an ice pack or a wet towel on the neck, chest, underarm or groin, and Accompanied by the fan, in short, all the methods that can be thought of.
At the same time, the body temperature was monitored, the rectal temperature was measured with anal thermometer (central body temperature), the anatomic thermometer was inserted into the anus instead, or the ear temperature was used to measure the ear temperature instead. The temperatures on the skin surface are not reliable.
Once the central body temperature falls below 39 degrees Celsius, the limbs and skin surface should be massaged at the same time, so that the cooler blood flow to the center and exchange with the hotter blood.
The third step, foreign aid and evacuation:
Patients with heatstroke often have multiple organ damages such as the brain nervous system, heart, kidneys, and liver. If patients have disturbance of consciousness or unstable life signs, regardless of first aid results, they should seek assistance from outsiders for the fastest possible time. Medical assessment and assistance. 
Prevention of Heat Stroke Three Tips People who have been in air-conditioned rooms or lack of exercise for a long time suddenly engage in intense activities in high temperatures and will be more prone to heat stroke.
Through proper training, the human body will have a certain degree of adjustment to the hot environment. The time required for such adjustment will vary from person to person. It usually takes two to three weeks.
In the summer outdoor activity before the start, leaving the air-conditioned room to do some outdoor physical activities, twice a day hot bath, or sauna steam bath, can help the body to adjust.
1. Active intake of water and salt:
Dehydration can prevent our body from radiating heat and induce heat stroke. When we are in violent outdoor activities, we will quickly lose a lot of water.
It is not enough to feel thirsty and drink water. It is recommended to use urine emissions and colors as indicators.
The frequency of urination is similar to that of peace, and the color is transparent or yellowish, indicating that the water intake is sufficient; if the urine volume is reduced or the color is very dark, there is a situation of dehydration, and it should take the initiative to drink plenty of water. When you drink plenty of water, you can add a little salt in the kettle or put a few plums, sports drinks can also be to avoid hyponatremia. There are good cold water bottles on the market today that can be used to hold cold drinks to help the body to radiate heat, but the total intake of water is the most important.
2. Light color clothing is preferred:
Light-colored clothing reflects sunlight, reduces absorption of infrared light into heat energy, and looseness facilitates exchange of air flow. For example, thin cotton yarn clothes are suitable for summer wear.
Or wear wicking underwear, sweat can be discharged to the surface of clothing to increase the effect of heat. Avoid wearing airless clothing and shoes at noon.
In addition, wearing a breathable hat, resting in a shaded area, fanning a fan, or washing your face with a towel is a good method of heat dissipation.
3. Avoid the daylight:
Poor environment sometimes does not discuss the room, please don't be forced. Every day from noon to about three o'clock in the afternoon is the hottest time of the day. If the sun is really hot, consider finding a cool lunch break and schedule the main trip in the early morning and early evening.
