Heat stroke in Western clinical medicine, known as environmental and physical and chemical injury diseases, is a disease formed by the external environment and the human body together, and can be divided into aura heat stroke, mild heat stroke and severe heat stroke. “A little heatstroke” can be understood as aura heatstroke, usually after a period of work in a hot environment, generally manifested as dizziness, headache, sweating, thirst, general fatigue and other symptoms, body temperature can be normal or slightly elevated. You can first go to a cool and ventilated place to rest for a period of time, supplemented with salt water, and can generally return to normal. If there is an aggravation of the above symptoms, the body temperature rises above 38 ℃, there is a lot of sweating, flushed face, burning skin and other performance, or appear pale, wet and cold skin and limbs, pulse increases and other signs of deficiency, then it may be from the aura of heatstroke into the stage of mild heatstroke. At this time, in addition to quiet rest in a cool, ventilated place, supplemental saline. Glucose saline can also be given intravenously according to the situation to play a role in replenishing sodium ions and cooling, while body rubs or other methods of physical cooling can be given. If treated promptly, most patients can recover within a few hours. If they enter the stage of severe heat stroke, heat cramps, heat exhaustion, or even pyrexia, they must immediately go to the hospital for emergency treatment, or their lives may be at risk. Therefore, you should avoid activities in environments that can easily cause heat stroke, and reducing the temperature and humidity of the environment and enhancing ventilation are effective ways to avoid heat stroke. Improving personal habits, drinking more water or supplementing with light salt water in a hot environment, and not wearing tight and impermeable clothing and pants can also effectively avoid heat stroke. In short, for aura heatstroke or mild heatstroke, you can basically recover quickly under the premise of cooling, ventilation, and adequate rest.
