Sunstroke, mainly the result of body being exposed to a high temperature for too long a time, can be described as a condition in which the body's ability to regulate heat fails.
Symptoms of sunstroke: Headache, muscle cramps, fatigue, dizziness, hot dry skin, flushed skin, high body temperature, lack of sweating, rapid pulse, rapid breathing, seizures, loss of consciousness.
Treatment For Sunstroke:
Get yourself out of the sun as soon as possible. Get inside an air-conditioned building or at least go under some shade.
Next, remove as much of your clothing as is possible, especially your shoes, socks and hats. This is because such clothes make the heat remain trapped inside.
Drink lots and lots of water and other fluids, except alcohol and caffeinated beverages. Don't gulp it all down, in one go. Rather, sip as much as you can take in.
After resting for a few minutes, take a cool shower. If it is not possible to have a bath, at least apply water to your forehead, neck, face and arms.
Then lie down on a flat surface and place a cool, damp cloth over your forehead. Elevate your feet, above your head, allowing blood to circulate and get rid of headache and dizziness.
In sunstroke, the body does not only lose fluids, but salts as well. Replenish the same by drinking a sports drink especially formulated with electrolytes or eating something salty.
You should start feeling better by this time. However, if this is not the case, it is advisable to seek immediate medical attention.
Some More Remedies:
Place ice packs at the neck, armpits, and groin. You can also rub the limbs with ice cubes.
Massage the arms and legs gently. This will allow some cool blood to return to the brain as well as the core of the body.
If the temperature is not coming down, you can wrap up the body with a wet sheet or towel.
You can also apply a cold mud pack to the stomach and eyes. This will help keep the body cool.
