This concept was introduced by psychologist Abraham Maslow. The pyramid serves as a roadmap for understanding what drives human behavior and fulfillment. As it relates to trauma, and the mind, one's needs must be met physiologically first to regulate and move your body into a "safe" state, ironically the next phase of the hierarchy. The Pyramid of Human Needs: Physiological Needs: At the base of the pyramid lie our most fundamental needs—food, water, shelter, and sleep. These primal requirements must be met for survival and form the foundation upon which all other needs build. Safety Needs: Once our physiological needs are reasonably fulfilled, we seek safety and security. This encompasses personal security, financial stability, health, and protection from physical or emotional harm. Love and Belongingness: As we move up the pyramid, our focus shifts to social needs—affection, relationships, friendship, and a sense of belonging within communities or social groups. Esteem: Beyond social connections, we yearn for recognition, respect, and self-worth. Esteem needs involve both external factors like status, success, and prestige, as well as internal factors like self-confidence and accomplishment.
