Answer:
Paradoxical undressing
Step-by-step explanation:
Hypothermia is the condition in which the body's core temperature drops below 95° Fahrenheit, a temperature at which the body's organ physiology is altered and can potentially begin to shut down, causing heart attacks, brain damage, respiratory failure, and more.
Some symptoms to be expected would be shivering, confusion, weak, possibly thready pulse, slowed speech, loss of consciousness, and pallor. Think of what Jack experienced in the movie Titanic. Another symptom in patients experiencing severe hypothermia is the phenomenon known as "paradoxical undressing," in which the patient disrobes themselves for unknown reasons, likely as a result of the aforementioned confusion leading them to believe they are more warm than they actually are, a false sense of safety.
Excessive hydration would lead to excessive sweating which would inevitably cool the skin, and thereafter the body, even more than before. This would not be a symptom of hypothermia.
Same with warm skin. If the skin is warm to the touch, especially on the patient's core, this means the patient may not be experiencing hypothermia. They may be experiencing hyperthermia, or their skin is at normal body temperature of 98.6° Fahrenheit.
