Which of the following is NOT a sign or symptom of heat stress?

1. Dizziness and fainting

2. Clammy skin

3. Hot, dry skin

4. Feeling cold

The correct answer is: Feeling cold

Feeling cold is not a sign or symptom of heat stress. Instead, heat stress occurs when the body overheats, typically due to excessive exposure to high temperatures, physical exertion, or both. The body's natural response to overheating includes symptoms such as dizziness, fainting, clammy skin, and hot, dry skin. Dizziness and fainting are common signs as the body struggles to regulate temperature and can lead to fainting from heat exhaustion. Clammy skin indicates the body's attempt to cool down through sweating, which may occur with heat-related illnesses, especially when high humidity prevents effective evaporation. On the other hand, hot, dry skin occurs when the body has lost its ability to sweat effectively, which is typical of heat stroke. Therefore, feeling cold stands out as an outlier among these symptoms and does not align with the physiological responses seen in heat stress situations.
