Dehydration occurs when the body looses too much of its water content and its blood and tissues are unable to function properly. This is a common problem that occurs with beach goers who spend a large amount of time at the beach on a hot day while engaging in physical activities without keeping themselves hydrated.

Dehydration can lead to a multitude of hazardous health conditions such as cramps, exhaustion, elevated body temperature, and even deadly heat stroke. The body must have adequate fluids in order for its skin, muscles, and brain to work properly. In extreme weather conditions such as cold and heat, a hydrated body can better maintain its core temperature of 98.6 degrees. Therefore, it is important to come to the beach with adequate amounts water to prevent yourself from being overheated in the hot sun, or from getting too cold from the cool water temperatures of the ocean.
