Question

A person working in a hot environment who consumes more water without salt is likely to develop a condition called

• A. Heat stroke
• B. Heat exhaustion
• C. Heat cramps
• D. Heat hyperpyrexia

Hint:

Think about what happens to muscles when the body loses salt faster than it replaces it.

Answer 1

The Correct Option is C

Sweating in a hot job removes both water and salt from the body. This question describes someone who drinks a lot of water back but skips the salt, and asks what this causes.

1. Heat stroke: A severe, high body temperature emergency, often with no sweating and confusion. It is not about salt replacement, so it does not fit.
2. Heat exhaustion: Comes from losing both water and salt together, causing weakness and dizziness, but it is not defined by a water only replacement pattern.
3. Heat cramps: Happens exactly when someone replaces sweat losses with water alone and skips the salt. Blood sodium drops, and the working muscles cramp painfully. This matches the question perfectly.
4. Heat hyperpyrexia: Another term tied to a dangerously high core temperature, similar to heat stroke, not to a salt deficiency picture.

The clue, more water without salt, points straight at low blood sodium from unbalanced replacement, which is the defining cause of heat cramps.

Let's summarize:

• Sweat carries away salt along with water, so replacing only water can drop blood sodium.
• Low sodium from this pattern causes painful muscle cramps, known as heat cramps.

So the condition this worker develops is heat cramps.
