👉 Hibernation, also known as slumbering or lethargy, is a state of inactivity and reduced metabolic rate during sleep. It is often associated with periods of low activity and decreased energy expenditure. Inhibiting metabolism and reducing body temperature during sleep can help regulate the body's internal environment and prevent overheating. This is particularly important for infants who are still developing or older adults who may have a compromised immune system, as it helps to conserve energy and maintain optimal health.
