Question

Which of the following are possible outcomes associated with dehydration?

1) Increased fatigue
2) Increased thirst
3) Increased heat tolerance
4) Increased muscle weakness

Answer 1

Dehydration can lead to increased fatigue, increased thirst, reduced heat tolerance, and increased muscle weakness, with impaired heat regulation being a notable consequence. Increased heat tolerance is not a result of dehydration.

Step-by-step explanation:

Possible outcomes associated with dehydration include:

• Increased fatigue: Dehydration decreases blood volume and causes cells to shrink, which can lead to feelings of tiredness and weakness.
• Increased thirst: As the body loses water, it needs to signal the need for replenishment, leading to an increased sensation of thirst.
• Increased heat intolerance: Dehydration can impair the body's ability to regulate temperature, reducing heat tolerance and potentially leading to heat-related illnesses.
• Increased muscle weakness: Loss of water and electrolytes can lead to muscle cramps and weakness, affecting physical performance.

It's important to note that dehydration does not lead to an increased heat tolerance, rather it can compromise the body's ability to handle heat. Therefore, one of the listed potential outcomes, increased heat tolerance, is incorrect in the context of dehydration.
