Heat stroke is a condition caused by your body overheating, usually as a result of prolonged exposure to or physical exertion in high temperatures. This most serious form of heat injury, heatstroke can occur if your body temperature rises to 104 F (40 C) or higher. After suffering a stroke you may be overwhelmed by confusion, concern, resentment and a host of questions regarding what to do next. May is stroke awareness month and everyone should set aside at least a few minutes this month to familiarize themselves with the signs and risk factors for stroke. Stroke – unlike other ailments, is a disease that is 80% preventable.
Stroke Warning Signs: Sudden weakness or numbness of the face, arm, or leg. Sudden confusion and trouble speaking or understanding. Sudden trouble seeing in one or both eyes. Sudden trouble with walking, dizziness, loss of balance or coordination. Sudden, severe headache with no known cause.
The risk of heat stroke can be reduced by observing precautions to avoid overheating and dehydration. Light, loose-fitting clothes will allow perspiration to evaporate and cool the body. Wide-brimmed hats in light colours help prevent the sun from warming the head and neck. Vents on a hat will help cool the head, as will sweatbands wetted with cool water. Strenuous exercise should be avoided during daylight hours in hot weather, as should remaining in confined spaces (such as automobiles) without air-conditioning or adequate ventilation. In hot weather, people need to drink plenty of cool liquids to replace fluids lost from sweating. Thirst is not a reliable sign that a person needs fluids. A better indicator is the colour of urine. A dark yellow colour may indicate dehydration.
