During military training, the eyes suddenly couldn t see anything

Sudden invisibility of the eyes during military training may be caused by insufficient blood supply to the brain, low blood sugar, or damage to the cornea by ultraviolet rays.

During military training, we often need to stand for a long time, and the long-term gravity makes the blood return of the lower limbs slower, resulting in insufficient blood supply to the brain, resulting in dizziness and dizziness symptoms.

High-intensity training during military training consumes a lot of energy, if you don't replenish energy in time, it is easy to have low blood sugar, and in severe cases, you will feel dizzy and even faint, at this time we should replenish blood sugar in time, such as timely replenishment of glucose water to relieve symptoms.

Military training is usually carried out under the scorching sun, long-term direct sunlight to the eyes is easy to cause corneal and fundus damage, compared to the above two conditions are more serious, if the eyes suddenly do not see during military training and the symptoms are still not improved after rest, activity and blood sugar supplementation, you should go to the hospital in time for examination, if there is a significant decrease in vision and obvious edema symptoms of the fundus, it means that the macular area has been damaged by ultraviolet rays, and you need to cooperate with the doctor in time**.

In short, when we are unwell during military training, we should report to the instructor in time, deal with it in time, and don't take our physical health as a child's play.

That's heat stroke!

Symptoms of premonitory heat stroke.

In a high temperature environment, symptoms such as headache, dizziness, thirst, sweating, weakness and soreness in the limbs, lack of concentration, and uncoordinated movements occur. Normal or slightly elevated body temperature. If you move to a cool and ventilated place in time and replenish water and salt, it can be restored in a short time.

Mild symptoms of heat stroke.

Body temperature tends to be above 38 degrees. In addition to dizziness and thirst, there are often manifestations such as flushing, profuse sweating, and burning, or clammy and cold limbs, paleness, decreased blood pressure, and increased pulse. If treated promptly, recovery can often occur within a few hours.

Severe heat stroke symptoms.

As the name suggests, it is one of the most serious cases of heat stroke, and if not treated in time, it will be life-threatening. This type of heat stroke can be further divided into four types: heat cramps, heat exhaustion, sunstroke, and heatstroke.

Characteristics of heat cramps: It mostly occurs when there is a large amount of sweating and thirst, drinking too much water and insufficient salt supplementation, resulting in a rapid and significant decrease in the concentration of sodium chloride in the blood. This type of heat stroke occurs when the muscles suddenly develop paroxysmal spasms.

Symptoms of heat exhaustion: This type of heat stroke often occurs in the elderly and people who are unable to adapt to the high temperature for a while. The main symptoms are dizziness, headache, palpitation, thirst, nausea, vomiting, clammy cold, blood pressure drop, syncope, or confusion.

Body temperature at this time is normal or slightly high. Symptoms and characteristics of sunstroke: The cause of this type of heat stroke is just like its name, because directly under the exposure to the scorching sun, strong sunlight penetrates the head** and skull, causing damage to brain cells, which in turn causes congestion and edema of brain tissue; Since the head is the main victim, the initial discomfort is severe headache, nausea and vomiting, irritability, followed by coma and convulsions.

Symptoms and characteristics of heat stroke: There are also some people who engage in physical labor in a high temperature environment for a long time, and the body produces too much heat, and the heat dissipation is insufficient, resulting in a sharp increase in body temperature. In the early stage of the disease, there is a large amount of cold sweat, followed by no sweating, shallow and rapid breathing, thin pulse, restlessness, confusion, and decreased blood pressure, and gradually develops into a coma with convulsions of the limbs; In severe cases, cerebral edema, pulmonary edema, heart failure, etc.
