Signs that heat stroke is approaching
Heat stroke is overheating. It happens when the body for some reason cannot cool, that is, return to a healthy temperature. It considers values up to 37.7 ° C.
The reasons for overheating can be different: heat, high physical activity, lack of moisture in the body … In general, it does not matter. Heat stroke is equally dangerous regardless of what caused it.
Sunstroke is a special case of thermal shock. This is a local overheating of the head caused by direct sunlight.
Fortunately, heat stroke does not occur simultaneously. He has a harbinger – thermal exhaustion. This is an increasing condition that signals: the body can not cope with thermoregulation, it needs to urgently help cool down.
Thermal exhaustion can be recognized by the following signs in various combinations:
- Pale, cold, clammy skin.
- Weakness and confusion.
- Sensation as if dark in eyes.
- Increased sweating.
- Nausea, slight vomiting.
- Muscle cramps and cramps.
- Dark urine (color indicates dehydration).
Symptoms of Heat Stroke
If you missed the stage of thermal exhaustion and it came to heat stroke, the symptoms will be even more unpleasant:
- Body temperature is above 40 ° C.
- Labored breathing.
- Profuse vomiting.
- Serious heart rhythm disturbances.
- Possible damage to internal organs due to heat shock.
- Brain malfunctioning.
All this is very dangerous, not only your health, but also your life is at stake. Therefore, take urgent action. Moreover, it is desirable already at the stage of thermal exhaustion.
First aid for heat exhaustion
If we are talking only about the initial symptoms of overheating, the first aid algorithm looks like this.
- Stop physical activity.
- To leave the sun (to leave a hot room) in the shade, in a light draft, into a room cooled by air conditioning.
- If possible, take off all clothing.
- Put cheesecloth or towel soaked in cool water on your forehead.
- Drink at least 1-2 glasses of water. This is necessary to eliminate possible dehydration and give the body moisture to produce an adequate amount of sweat.
- Drink rehydron or isotonic sports drink. Such a liquid contains electrolytes important for the metabolism and functioning of the nervous system. And you could lose them with intense sweating.
First aid for heat stroke
If you or someone around you has already suffered a heat stroke, on-site assistance may not be effective. There is vomiting, cardiac abnormalities, fainting – immediately call an ambulance.
Heat stroke refers to an emergency medical condition, and a person surviving it needs emergency assistance.
As the ambulance travels, follow the same procedures as for thermal exhaustion. To increase the effect, they can be supplemented with “heavy artillery”:
- Cover the victim with ice packs (frozen vegetables and berries are also suitable) wrapped in a thin sheet.
- Put the person in a bath of cold water to quickly reduce the critical temperature. Attention: this advice can be used only if other people help you (the victim). Diving into water alone is dangerous.
Arriving doctors will evaluate the patient’s condition. If the first-aid first aid for heat stroke was provided on time and it was effective, hospitalization will not be needed. Nevertheless, doctors can put a dropper to compensate for electrolytes lost with moisture, and will advise you to take blood and urine tests and an ultrasound scan to determine the condition of the internal organs. Go to the therapist with the test results. He will say what to do next.
If you have suffered a heat stroke, then in the coming week you will be especially sensitive to high temperatures. Therefore, carefully observe these precautions.
- Drink more water
Optimal – 2–4 cups of liquid (water, fruit and vegetable juices) every hour that you spend in direct sunlight at high temperature. Especially if in the heat you still do physical labor. To sweat effectively, your body needs more moisture than usual. Do not allow its deficit.
- Try to spend the hottest hours indoors
In summer, the interval between 11:00 and 15:00 is considered dangerous. During this period, avoid physical activity in direct sunlight.
- Wear light, light clothing
Clothing should be as loose as possible to facilitate air circulation around the body.
- Do not forget about the headgear
A hat or panama can help prevent sunstroke. A cap and a bandanna on a hot day are not very suitable: it is better to choose a light hat and with wide brim.
- Take a cool shower or bath more often.
This will lower body temperature.
- Do not drink alcohol or caffeinated beverages
They promote dehydration and spasm of blood vessels. Because of this, the body produces less sweat than is needed for cooling.
- Monitor urine color
Dark is a sign of dangerous dehydration.
