Preventing the symptoms of dehydration requires you to drink the right amount of water. So, how much water is that? Typically, it is half your body’s weight in ounces of water. This means that a 200-pound person needs to drink half of 200, which is 100 ounces of water daily, to avoid dehydration. It is important to focus on more than just preventing the symptoms of dehydration. Make it your goal to be properly hydrated. This means drinking an extra 20 ounces. Therefore, a 200-pound person should drink 100+20=120 ounces of water each day. If you tend to perspire a lot, such as an athlete, you may need to drink more than 20 ounces of water each day to stay properly hydrated.

Preventing the Symptoms of Dehydration: Protein Deficiency
Your brain uses broken-down proteins, called amino acids, to signal thirst. If you do not have enough amino acids to signal thirst, you will not have a desire to drink water. Therefore, it is extremely important to keep your complete protein intake high enough to provide all the protein you need for your brain to signal thirst.
