What should someone do to prevent hypothermia?

1. take allergy medication

2. wear sunscreen and sunglasses

3. wear thin clothes and stay hydrated

4. stay inside when there is an extreme cold alert.

1. This answer is incorrect. Allergy medication does not prevent hypothermia.

2. This answer is incorrect. Wearing sunscreen and sunglasses is important for protecting against the sun's rays but is not directly related to preventing hypothermia.
3. This answer is partially correct. Wearing thin, layered clothing is important to regulate body temperature, but staying hydrated is not directly related to preventing hypothermia.
4. This answer is partially correct. Staying inside during extreme cold alerts can certainly help prevent hypothermia by avoiding exposure to dangerously low temperatures.

Correct answer: Wear warm, layered clothing, including a hat and gloves, to retain body heat. Avoid prolonged exposure to cold temperatures, especially in wet conditions. Seek shelter and warm up indoors if you begin to feel cold or experience symptoms of hypothermia.
