The Top 10 Signs of Dehydration

The human body is made up of approximately 70-percent water. So it makes sense that fluids are vital for the majority of our bodily functions—protecting our joints, maintaining organ function, transporting oxygen to cells, and sustaining body temperature. It also makes sense that the body can become dehydrated fairly quickly due to excess perspiration, hot weather, sun exposure, and lack of fluids throughout the day.

However, if you’re active or if you sweat excessively, replenishing water levels regularly throughout the day is even more detrimental to prevent dehydration. Here are the ten telltale signs (in no particular order) that your body is experiencing dangerous dehydration:

1. Fatigue Sets In

When the body suffers from chronic dehydration, blood flow and blood pressure drop due to a lack of water and oxygen in the blood. Basically, dehydration results when the body loses more water than it takes in. This naturally causes the muscles and nerve function to literally burn out due to profuse sweating after exertion. 

If you have the stomach flu, and are suffering from water loss (due to a combination of vomiting and/or diarrhea) you will often feel fatigued. This is why doctors will recommend plenty of rest along with plenty of fluids, like water, juice, and herbal teas to replenish lost water levels.
