Why do all animals need sleep?

From a perspective of energy conservation, one function of sleep is to replenish brain glycogen levels, which fall during the waking hours. In keeping with this idea, humans and many other animals sleep at night. Furthermore, body temperature has a 24-hour cycle, reaching a minimum at night and thus reducing heat loss.

Why is sleeping necessary for humans and animals?

From a perspective of energy conservation, one function of sleep is to replenish brain glycogen levels, which fall during the waking hours. In keeping with this idea, humans and many other animals sleep at night.
