Why do camels lie down for a long period of time?

Camels lie down for long periods primarily to conserve energy and regulate their body temperature. By resting, they reduce their metabolic rate and minimize water loss, which is crucial in their arid habitats. Additionally, lying down allows them to ruminate, helping with digestion, as they are herbivores that consume tough plant materials. This behavior also provides a chance for social interactions and rest after periods of activity.
