Heat stroke

This is some text inside of a div block.

Heat stroke is a medical emergency when the body cannot regulate its temperature. It is caused by prolonged exposure to high temperatures, usually in combination with dehydration. Heat stroke can be life-threatening if not treated quickly.

The cause of heat stroke is prolonged exposure to high temperatures. This can occur when a person is working or exercising in hot weather or a hot environment without adequate ventilation. Dehydration can also increase the risk of heat stroke.

The symptoms of heat stroke include a high body temperature (over 104°F), confusion, headache, dizziness, nausea, rapid breathing, and a rapid pulse. In addition, the skin may be hot and dry, or it may be sweaty.

If you suspect someone is suffering from heat stroke, it is essential to act quickly. Move the person to a cool, shaded area and remove any excess clothing. Apply cool, wet cloths to the skin and fan the person to help cool them down. Give them small sips of cool water if they can drink. Seek medical attention immediately.
