• 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 cooler, shaded areas should be used if possible. Of course, people should be monitored to make certain they are safe. Those working in hot environments need to take care to rehydrate often. In heat waves, it is important to routinely check on neighbors, especially the elderly or those that do not have air conditioning.

• Environment: People exercising and working in a hot environment need to drink adequate amounts of water. People can become dehydrated in the ocean, lakes, or pools if the water and and environmental temperatures are warm enough.
• Age: The young and elderly are most at risk because of poor temperature regulation systems. 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 from heat exposure.
• 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.

• The body needs water to function.
• Dehydration occurs when water intake is less than water loss.
• Symptoms range from mild to life-threatening.
