Dehydration Tips

by Andrew Vertson

Summer is now here… as we approach the “heat of the summer” you should be aware of your need for fluids. If you are exercising, spending time in the sun, or are under the weather, you can more easily become dehydrated. Once dehydration starts your body begins to shut down, except for vital functions. Luckily the body gives us symptoms to prevent dehydration from happening.

The body will react to the need for water by giving of signs that you should recognize. The initial signs and symptoms of mild dehydration, in adults, start to appear when a person has lost approximately 2% of their total fluid.

Dehydration symptoms:

  • Dry lips and thirst
  • Dry, flushing , skin
  • Fatigue, muscle weakness

Urine color Warning Sign:

We don’t have a water gauge to determine how dehydrated our body is but our body does provide us some indication of our level of hydration. The best indicator is the color of our urine. A clear, or slightly colored, urine shows good hydration while a dark yellow urine color signals dehydration.

How much water should you consume?

You have probably heard many experts say eight, 8 ounce, glasses of water per day. That is a good start but if you are extremely active, work in a hot environment, or live in a warmer climate that might not be enough.
A good indicator of water intake is 50 to 75% of your body weight in ounces. For the average person: take your body weight, cut it in half, and that is the number of ounces you should drink in a day. If you are more active, or work/live in a hotter environment, then add 25% more to your number of ounces. Dehydration Tips
