It is important to be aware of symptoms of dehydration to help ensure the safety and effectiveness of a personal workout, as well as to recognize when a workout partner may be in need of fluids. Symptoms of dehydration range from mild and easy to severe and potentially life threatening.

Mild symptoms of dehydration are sometimes slight and easy to miss. Early signs of dehydration may include increased thirst, concentrated dark yellow urine, a dry mouth, headaches, weakness, irritability or cramping. Severe symptoms of dehydration are more blatant and need to be addressed quickly by a healthcare provider. Severe symptoms of dehydration include extreme thirst, no urine or tears, fainting, rapid heart rate, low blood pressure, fast and weak pulse, sunken eyes, altered mental status, and skin dryness.
