Guard against! Easy summer heat eight categories of people

Doctors advise: In the hot weather must be careful of heat stroke, and compared with ordinary people, some poor physical fitness or other diseases are more prone to heat stroke, so in the hot weather more should pay attention to themselves and their families .

　　The reasons are three heat

The body heat stroke and heat radiation at high temperature under a long time, body temperature regulation in problems of water and electrolyte metabolism disorders and symptoms of nervous system damage, collectively, is the heat balance function disorders and a kind of emergency occurs. Can be divided into three kinds:

 

One is in the hot room prone to heatstroke. Patients will feel headache, dizziness, thirst, and then the rapid temperature rise, the pulse speed up, facial redness, and even coma.

 

The second is a sunstroke. If people activities or stay under the hot sun for too long, directly in the sun exposure, the strong sunlight penetrate the skin and skull caused by head and brain cell damage, it will cause the brain tissue hyperemia, edema.

 

Is mainly due to head injury, so the beginning is only the head temperature increases, high over time can reach 39 ℃, and then there are severe headache, nausea and vomiting, irritability, followed by coma and convulsions can occur, but the temperature does not necessarily increased.

 

The third is called heat cramps. People in high-temperature environment, the body will sweat a lot, lost a lot of salt, so that the sodium content in the blood is too low, causing leg cramps and even limbs and muscles.

 

　　Heat stroke symptoms are light to heavy

In heat stroke, when there are the severity of different clinical manifestations. High-temperature environment, people could start a "sign of heat stroke," reflected in sweating, thirst, weakness, dizziness, vertigo, tinnitus, nausea, heart palpitations, inability to concentrate, numb extremities, incoordination and so on. At this time, if the timely transfer to a cool well-ventilated place to supplement the water and salt can be restored within a short time. If these symptoms get worse, the patient's body temperature rose to above 38 ℃, facial flushing or paleness, sweat, skin clammy, pulse thin and delicate, fast heart rate, blood pressure decline is likely to be mild heat stroke, the need for timely treatment, and rest.

 

Severe heat stroke, most patients are in the high-temperature environment, the onset of coma. Patients often had headaches, numbness, dizziness, anxiety or mental disorder, disorientation, physical symptoms such as not at liberty to exercise, the skin to stop sweating, dry, hot and bright red, the body temperature often above 40 ℃.

 

　　8 kinds of people tend to heat stroke

1. Older people: As the sweat glands of skin atrophy and circulatory function decline, poor body heat.

 

2. Pregnant women: they are pregnant or postpartum physical exertion big, physical weakness, if long-term stay in poor ventilation, high indoor temperatures, it is easy to heat stroke.

 

3. Infant and young child: Infant inadequate development of the various systems, body temperature regulation function is poor, subcutaneous fat and relatively more detrimental to the heat.

 

4. Cardiovascular disease: the hot weather will make cardiovascular disease the sympathetic nervous excitement, increase cardiovascular capacity. In particular, cardiac dysfunction, and they heat the body can not be timely dissemination of the savings, therefore, prone to heat stroke.

 

5. Diabetes: Diabetic patients with body temperature of the internal and external environment has been insensitive, although the heat has been stored in the body, but the patient's symptoms have emerged relatively late, easy to heat stroke.

 

6. Infectious disease: suffering from a number of infectious disease patients, because of bacterial or viral infections can make the body produce endogenous pyrogen, so that the body heat to accelerate. Inflammation also enables the body to release some material, so that contraction of vascular spasm, more heat is not conducive to heat dissipation and easy.

 

7. Malnourished people: people who are malnourished because of the lack of nutrients, leading to decreased blood pressure to rise to reflex contraction of blood vessels. They are prone to repeated diarrhea, leading to dehydration and electrolyte imbalance, leading to heat stroke.

 

8. Is medication for patients: taking anti-histamine drugs, anti-cholinergic drugs, sleeping pills and so people will vasoconstriction, so that the occurrence of impeding thermoregulation center, easy to heat stroke.
