How much of the average person's daily water intake is from food?
- A.

10%
- C.
20%
- D.
14.25%
Correct Answer
C. 20%Explanation
On average, 20% of a person's daily water intake comes from food. This is because many fruits and vegetables have high water content, contributing to the overall hydration of the body. Additionally, soups, stews, and other liquid-based foods also contain water. While it is important to drink water throughout the day, consuming water-rich foods can also help meet the body's hydration needs.Rate this question:

Exercise in hot, humid conditions can cause significant dehydration in as quickly as 30 minutes.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Exercise in hot, humid conditions can cause significant dehydration in as quickly as 30 minutes. This is because when we exercise in hot and humid conditions, our body temperature rises, causing us to sweat more in order to cool down. This excessive sweating leads to a loss of fluids and electrolytes, which can quickly lead to dehydration. Additionally, the high humidity in the air makes it harder for the sweat to evaporate, further increasing the risk of dehydration. Therefore, it is important to stay hydrated and drink plenty of fluids when exercising in hot and humid conditions.Rate this question:

While exercising, most people should break for water every 20 minutes.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
It is important to stay hydrated while exercising to prevent dehydration. Drinking water every 20 minutes allows the body to replenish the fluids lost through sweat and maintain proper hydration levels. This helps to regulate body temperature, prevent muscle cramps, and improve overall performance during exercise. Therefore, taking breaks for water every 20 minutes is recommended for most people to ensure optimal hydration and prevent any potential health risks associated with dehydration.Rate this question:

Which of the following beverages is considered to be the most dehydrating?
- A.
Coffee
- B.
Alcohol
- C.
Milkshake
- D.
Coke-cola
Correct Answer
B. AlcoholExplanation
Alcohol is considered to be the most dehydrating beverage because it is a diuretic, which means it increases urine production and causes excessive fluid loss from the body. This can lead to dehydration if not enough water is consumed to compensate for the fluid loss. Coffee and Coke-cola also have diuretic effects, but alcohol is generally more dehydrating due to its higher alcohol content. Milkshake, on the other hand, does not have diuretic properties and therefore is not as dehydrating as the other options.Rate this question:

You can't drink too much water while exercising
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Drinking too much water while exercising can lead to a condition called hyponatremia, which is a low concentration of sodium in the blood. This occurs when excessive water intake dilutes the sodium levels in the body, potentially causing symptoms like nausea, headache, confusion, seizures, and in severe cases, even coma or death. Therefore, it is important to drink water in moderation and listen to your body's hydration needs while exercising.Rate this question:

This includes water in organs, muscles, and other bodily fluids such as lymph and cerebrospinal fluid. The bloodstream only accounts for a smaller portion of the body's total water content.Rate this question:

Is being thirsty the first sign of dehydration?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Thirst is not the first sign of dehydration. By the time a person feels thirsty, their body is already experiencing some level of dehydration. Thirst is the body's way of signaling that it needs more fluids, but it is not the initial indicator. Other early signs of dehydration include dry mouth, dark urine, fatigue, and dizziness. It is important to drink water regularly throughout the day to prevent dehydration, rather than relying on thirst as a signal to drink.Rate this question:
