Later that evening, the friend with the bad sunburn is bundled up and shivering even though the night temperature is 78º F. She has a headache (6 on a scale of 1-10), is nauseous, and eventually vomits once. The last time she urinated was on the hike; she doesn't remember the color. Her core temperature is 100.2º F, her pulse is 88 and regular, and she is breathing easily at 22 breaths per minute. Her normal pulse is 62 and regular.
