Heatstroke

What is it? The human body usually can regulate its temperature. When the body gets too hot, it uses several strategies to cool down, including sweating. But if a person spends too much time in the heat without taking in enough fluids, the body's cooling processes can't work properly. When the body becomes dehydrated, it can no longer cool itself by sweating. When this happens, body temperature can rise high enough to make the person sick. The first symptoms of heat illness occur as the body temperature climbs above normal, and can include headache, nausea, vomiting, muscle cramps and fatigue. These early symptoms sometimes are called heat exhaustion. If steps are not taken to reduce body temperature, heat exhaustion can worsen and become heat stroke. Heat stroke is a serious, potentially life-threatening form of heat illness. The body temperature rises to 105 degrees Fahrenheit or higher and you develop neurological changes, such as mental confusion or unconsciousness. At these high temperatures, body proteins and the membranes around the cells in the body, especially in the brain, begin to be destroyed or malfunction. The extreme heat can affect internal organs, causing breakdown of the heart muscle cells and blood vessels, damage to internal organs, and death. There are two main ca uses of heat stroke: • Exertional heat stroke occurs when someone is vigorously active in a hot environment, such as playing sports on a hot summer day or participating in military training a...

Heat stroke results in more than 600 deaths a year in the United States.

Young children or elderly adults left alone in a vehicle are at particular risk of succumbing to heat stroke. "Heat stroke in children and in the elderly can occur within minutes, even if a car window is opened slightly." Dogs are even more susceptible than humans to heat stroke in cars, as they cannot produce whole...

Michael V. Pettigano, NorthJersey.com The According to the NWS, Wednesday's heat index was projected to reach values from 105 to 108 degrees. What is a heat advisory? What temperature is considered a heat emergency? A heat advisory is typically issued by the National Weather Service in a 12-hour window before the onset of extreme or dangerous heat conditions. The rule of thumb for issuing a heat advisory is typically when the maximum heat index temperature for the day is anticipated to reach 105 degrees or higher. How long will The NWS announced Wednesday morning that most of South Florida could be under the extreme temperatures daily through Tuesday. Wednesday's heat advisory began at noon and extends until Friday evening. Heat index forecast: National Hurricane Center: What's the difference between heat index and real feel temperature? According to the The more moisture there is in the air, the harder it is for sweat to evaporate from your skin. We all know that sweat is your body's way of cooling you down, but that cooling process only happens when the sweat evaporates. The temperature's rising: How to avoid heat exhaustion or a heat stroke in dangerous temperatures According to the NWS, this is how you can prepare for a heat advisory to avoid a heat stroke in the extreme temperatures that South Florida will see this week. • Stay hydrated. • Stay out of the sun and in an air-conditioned space as much as possible throughout the day. • If possible, reschedule any strenuou...
