Question

which of the following is not an early sign of heat illness?
dizziness
headache
flushed face
excessive sweating

Explanation:

Dizziness, headache, flushed face, and excessive sweating are all common early - stage signs of heat illness. Since all the options are early signs of heat illness, this question may be misconstructed. But if we assume we must choose one, there is no correct 'not an early sign' among them.

Answer:

There is no correct option as all are early signs of heat illness.
