Maslow's Pyramid, often referred to as Maslow's Hierarchy of Needs, is a psychological theory proposed by Abraham Maslow in his 1943 paper "A Theory of Human Motivation". The theory posits that human beings have a set of needs that are hierarchical in nature; as one set of needs is satisfied, individuals seek to fulfill the next level of needs.

The pyramid is typically depicted with five distinct layers, from the most basic needs at the bottom to the highest form of needs at the top.

Physiological needs

At the base of the pyramid, these are the most essential requirements for human survival. They include food, water, warmth, rest, and breathing. If these needs are not met, the human body cannot function optimally.

Safety needs

Once basic physiological needs are addressed, individuals seek security and safety. This category includes protection from elements, security, order, law, stability, and freedom from fear.
