Heat stroke, heatstroke, heat spasms, heat exhaustionHeatstroke was a disorder of the central nervous system and circulatory system caused by the body's body temperature regulation in a high temperature environment. According to its mechanism, it can be divided into heatstroke, heat spasm, and heat exhaustion.
Heat exhaustion was a relatively mild form of heatstroke. It was mainly due to long-term activity in a high-temperature environment. After sweating a lot, the body lost too much salt and water, resulting in dehydration and insufficient blood circulation. There were symptoms such as hyperhidrosis, wet and cold skin, pale face, nausea, dizziness, significantly increased heart rate, low blood pressure, oliguria, etc., which could be accompanied by dizziness and syncope. The body temperature often rose but did not exceed 40 ° C. Some patients only had high body temperature in the early stage.
Heat spasms are caused by excessive sweating and loss of vitamins (especially loss of Na), resulting in muscle spasms and pain. Common symptoms include muscle spasms, pain, and cramps, which mostly occur in the muscles of the limbs, masticatory muscles, and abdominal muscles (especially the calf muscle). They are symmetrical, and the body temperature is generally normal.
Heatstroke was the most serious form of heatstroke. It was extremely harmful to human life and had a high mortality rate. When the body temperature is too high (more than 40 ° C), and the heat cannot be distributed through sweating and heat radiation, there will be severe central nervous system malfunction and circulatory system failure, such as high fever, loss of consciousness, convulsions, increased heart rate, breathlessness, hot and dry skin, etc. There may also be general convulsions, rhabdomyolysis, multiple organ malfunction syndrome, etc., which can easily lead to multiple organ failure.
In general, heatstroke was a broad concept. Heatstroke, heat spasms, and heat exhaustion were different types. Heatstroke was the most serious.

Extreme TouchIn the reference materials, there was a discussion about " touching the limit of the shooting range." In military exercises, soldiers faced situations where the range of their equipment exceeded the theoretical limit, which led to thinking about the definition of limits. This meant that the limit might not only be the limit of the equipment's performance, but it was also related to people's perception. Based on the soldiers 'practice, after repeated pondering and breakthrough training on the various parameters of the weapon and equipment, the potential of the weapon and equipment would be activated under the circumstances of a good external environment and skillful operation. The actual distance of hitting the target might exceed the limit value marked in the equipment manual, which meant that the limit was not a constant and insurmountable scale.
