Okay, as promised, although I only know of one person who took the quiz, here are the answers, and explanations.
1) B. Sleep troubles, and fatigue can signal dehydration.
So can dry mouth, thirst, decreased urine output, muscle fatigue, dizziness, and light-headedness.
2) D. Yep All of the above. The body can't tell the difference between wether it's getting water from a tap water, or lettuce. In fact, on average, 20% of total water intake comes from the food you eat.
3) C. The recommendation of 92-124 ounces comes fromthe Institute of Medicine. It may sound like a lot of water, but remember that you get more than a splash from your daily intake of food. Don't think you can rely on your parched throat to tell you when to imbibe. You should drink when you feel thirsty but that may not be enough, because by the time you are thirsty, you're already mildly dehydrated.
4) A. Pale yellow is the gold standard for urine color. Marked changes in your urine color may indicate that you are over or under hydrated.
5) C. Good news, java junkies. Caffeine is not a diuretic. Studies show that people who drink beverages containing up to 550 mg. of caffeine per day, (the amount of about 4 cups of coffee), produce no more urine than those who drink caffeine free beverages. In fact consuming caffeinated beverages, in moderation, contributes to your overall hydration for the day.
6) B. Cheers !An occasional beer or glass of wine counts as another source of fluid. The key is moderation. Alcohol is not recommended during times of increased physiological stress, including heat or before, during or after exercise.
7) D. Sports drinks may taste great, but they're not needed by typical weekend warriors. There is a lot of evidence to suggest that, for most people, water alone will get the job done. The sugar and electrolytes in sports drinks may improve serious athletes' performance, but most moderate exercisers don't require the added calories these beverages provide.
8) D. During exercise you lose water via sweat, and respiration. It's important to stay hydrated before, during, and after exercise, as well as throughout the day. Needs vary by person, but an extra 1 1/2 to 2 1/2 cups of water should be enough for most bouts of moderate activity. If you participate in strenuous endurance activities such as a triathlon, or marathon, you may need more.
Give yourself 5 points for every correct answer.

If you scored 0-20: Don't despair, now you know what your body needs.
