Every night, we say and hear "good-night." Sleep is an essential need, and a restful night's sleep is influenced by a number of things.
Over the course of an awake and conscious day, our cells get exhausted.

According to the restorative theory, getting enough sleep helps the body replenish its critical cellular systems and heal the wear and tear that comes with aging. A person's health and physical condition depend on getting enough restorative sleep.

Physical Recuperation: Following physical exertion, deep sleep promotes development and muscle, tissue, and cell repair.

Cognitive Function: It improves grasping, retention or memory consolidation, and deftness when solving problems. These abilities help you remain vigilant, focused, and aware throughout the day.

Emotional Parameter: Getting enough sleep is essential for reducing stress, controlling emotions, bolstering sound emotional intelligence, and maintaining clear thinking.

Immune Function: Getting a good night's sleep is essential to bolstering the immune system and defending the body against illnesses and infections.

Sleep deprivation is termed as a state when an individual does not get enough sleep. Though it may differ from person to person, anywhere between 7 to 8 hours of sleep is recommended and the quality matters as much since poor sleep inhibits essential happy hormones like dopamine.
