How can hypothermia be prevented?

Wearing layers of lightweight clothing is the most effective way to prevent hypothermia. This is because layers of clothing trap insulating air and prevent heat loss from the body. This option is better than fasting before a hunt (A) as fasting can actually make the body more susceptible to hypothermia due to its decreased ability to regulate body temperature. Hunting only in the daytime (C) may not always be possible and keeping movements to a minimum (D) can be counterproductive as physical activity generates body heat. Therefore, wearing layers of clothing is the most practical and effective way to prevent hypothermia.
