Find out with our True/False quiz.

1. For optimum health, drink 8 glasses of water per day.

 

False. Though water is inexpensive, other liquids will also hydrate

individuals, and some infused liquids have even more antioxidant benefit

than water. Adults should strive for 6-8 glasses of water per day, according

to Institute of Medicine recommendations, but those who exercise or stay

active should add one additional 8 ounce glass of water for each half hour of

moderate of strenuous exertion.

 

2. Yellow urine is a sign of dehydration.

 

False. The concentration of waste products in the urine determines the

color, and it is impossible to absolutely correlate urinary color with hydration

status. Other factors, such as good nutrition or multivitamin administration,

can also lead to yellow urine.

 

3. Sports drinks are superior to water in athletics.

 

False. Sports drinks may have a higher concentration of some minerals and

vitamins, but they are also loaded with sugar or other artificial sweeteners or

colors. Water, and especially infused waters, along with a whole-goods,

plant-based diet is the single best way to transport nutrients and energy and

remove heat during strenuous exercise. After exertion of longer than 2 ½

hours, however, the addition of salt tablets or other mineral and electrolyte

supplementation may be appropriate.

 

4. Drinking water flushes toxins from your body.

 

True. Water doesn’t neutralize toxins, but the kidneys, which are responsible

for waste management, are not able to remove metabolic wastes properly

without adequate water.

 

5. Drinking water can help keep your skin looking dewy.

 

True. Severely or chronically dehydrated people will experience to changes

in the largest organ of the body, the skin. The moisture level of the skin is

determined by external factors, such as humidity in the air or exposures, but

the amount of oil produced oil glands and water available for hydrating the

skin cells is directly related to the diet and hydration.

 

6. It’s possible to drink too much water.

 

True. People with severe psychological disorders can sometimes over

hydrate and experience very low body sodium levels, which can lead to

confusion and even seizures. Certain medical conditions often require

treatment with fluid restriction, such as heart failure or kidney failure.

 

7. Drinking water helps you lose weight.

 

True. Water not only replaces empty calorie-loaded beverages like pop or

flavored coffees; it also will make you feel fuller. So, you may eat less at a

meal if you start the meal with a stomach shrinking glass of ice cold water.

Ice cold water also uses up calories to warm to body temperature in your

stomach – between 25-40 calories per chilly glass – and that adds up to 5

pounds per year with regular consumption.

 

8. If you’re thirsty, you are already dehydrated.

 

True. Thirst begins when the concentration of substances in the blood

increases just under 2%. While dehydration is formally diagnosed when total

body water is decreased by 5%, it is better to avoid mild dehydration and

drink before actually sensing thirst.

 

9. You should not reuse plastic water bottles.

 

True. Plastic water bottles should be avoided unless they are clearly BPA

free. The bottles contribute endocrine-disrupting plastics that lead to thyroid

disorders and sex hormone instability. They can also harbor bacteria if they

aren’t properly cleaned between uses.
