Which of the following is NOT an aspect of treating heat exhaustion?

Applying ice directly to the skin is not a recommended aspect of treating heat exhaustion. Instead, when treating heat exhaustion, the goal is to gradually cool the body without causing additional harm. Direct application of ice can lead to skin damage or further complications by constricting blood vessels and impeding the natural cooling process of the body.

The other approaches mentioned are effective in managing heat exhaustion. Seeking medical attention is crucial if symptoms worsen or do not improve; using fans or sprinkling water helps in evaporative cooling; and administering small sips of water aids in rehydration without overwhelming the stomach, which can lead to complications like nausea.
