Dehydration's Warning Signs
Sweat loss reduces blood volume and increases the concentration of sodium in the blood. This stresses the cardiovascular system and contributes to a faster increase in body temperature. Dehydration results in a number of symptoms that are important to remember.
Performance Tip
Don’t Wait for the Warning Signs
Dehydration’s warning signs only occur when the body is already dehydrated. An athlete’s best bet for peak performance is to drink to minimize weight loss during exercise but avoid over-drinking.
