Babies under the age of 4 are prone to heatstroke.

The so-called heat stroke, in short, is the body produced by the heat can not be eliminated by the normal pipe, and then a series of symptoms. If your baby is less than 4 years old, you should be very careful. Babies under 4 are easiest to get heatstroke.

1. Temperature regulation center is not yet mature: the children’s temperature regulation center is not yet mature (usually about 10 weeks old before gradual development), so for the changes in ambient temperature, poor adaptability.

2. Bigger body surface area: the relative body surface area of a child’s unit weight is better than that of an adult’s, and it is easy to absorb the heat in the environment, but the circulation ability is poor, so it is not easy to transfer excessive metabolic heat to the body surface for dissipation. If the external temperature is too high, it can not dissipate heat, but absorb heat. Moreover, the skin of children is thin and the blood vessels are distributed widely, which is more susceptible to external high temperature. Therefore, infants and young children are not good at high temperature and high heat.

3. Poor perspiration function: when sweat evaporates on the skin surface, it can absorb heat from the skin and cool down (accounting for 20-25% of human heat dissipation). However, due to the small number of sweat glands on the skin and limited water storage in the body, this method of heat dissipation is not very useful.

4. Balance of loss: the metabolic rate of children is higher, more heat production, it is necessary to cooperate with a larger body surface area and faster breathing air in and out to maintain normal body temperature, but if the temperature of the surrounding environment is higher than body temperature, inhaled is hot air, on the contrary, will cause the body temperature to rise. (accounting for 10% of the calorific value).

3 clinical manifestations of heat stroke

1. Augural heatstroke: Headache, blindness, tinnitus, dizziness, thirst, palpitation, normal or slightly elevated body temperature appear in the high temperature environment, short rest can be restored.

2. Mild heatstroke: In addition to the above symptoms, the body temperature above 38 degrees Celsius, flushing pale complexion, sweat, skin wet and cold, blood pressure dropped, pulse increased, after rest, the baby can return to normal.

3. Severe heat stroke: also known as heat exhaustion, performance: cool skin; excessive sweating; nausea, vomiting; pupil enlargement; abdominal or limb spasm; rapid pulse; often accompanied by coma, coma, high fever and even loss of consciousness.

If the baby has these 4 conditions, he is suffering from heat stroke.

In what circumstances do mothers need to suspect children of heatstroke? If your child measures anus or ear temperatures above 39 or 40 degrees (not recommended armpit or mouth temperature, easy to underestimate the actual temperature), and when combined with the following phenomena, the likelihood of heatstroke should be highly suspected:

1, though it is very hot, it may not sweat. (this is one of the most typical cases of heat stroke).

2, the skin will be red, hot, and dry.

3. Anxiety and crying, breathing and pulse acceleration; then appear tired, or even into convulsions or coma.

4, the older children will feel dizzy, nauseous, lose their sense of direction, and be dizzy.
