Perhaps we can provide a small service by addressing Dehydration.
What are the signs and symptoms of dehydration?
The body's initial responses to dehydration are
*thirst to increase water intake along with
*decreased urine output to try to conserve water. The urine will become concentrated and more yellow in color.
As the level of water loss increases, more symptoms can become apparent. The following are further signs and symptoms of dehydration:
*dry mouth
*the eyes stop making tears
*sweating may stop
*muscle cramps
*nausea and vomiting
*lightheadedness (especially when standing).
The body tries to maintain cardiac output (the amount of blood that is pumped by the heart to the body); and if the amount of fluid in the intravascular space is decreased, the body has to increase the heart rate, which causes blood vessels to constrict to maintain blood pressure. This coping mechanism begins to fail as the level of dehydration increases.
With severe dehydration, confusion and weakness will occur as the brain and other body organs receive less blood. Finally, coma and organ failure will occur if the dehydration remains untreated.
Can dehydration be prevented?
Environment: Dehydration due to the weather is a preventable condition. If possible, activities should not be scheduled in the heat of the day. If they are, adequate fluids should be available and people should be monitored to make certain they are safe.
Those working in hot environments need to take care to rehydrate often.
Exercise: People exercising in a hot environment need to drink adequate amounts of water.
Age: The young and elderly are most at risk. During heat waves, attempts should be made to check on the elderly in their homes. During the Chicago heat wave of 1995, more than 600 people died in their homes.
Heat related conditions: Know the signs and symptoms of heat cramps, heat rash, heat exhaustion, and heat stroke. Preventing dehydration is one step to avoid these conditions.
