According to Maslow's Hierarchy, what need category involves physiological requirements like food and shelter?

In Maslow's Hierarchy of Needs, the category that involves physiological requirements such as food, water, warmth, and shelter is identified as Basic Needs. This foundational level emphasizes the most essential requirements for human survival and health. Until these basic needs are met, an individual is unlikely to focus on higher-level needs such as safety, love, esteem, or self-actualization. Understanding this framework is crucial for individuals working in healthcare and caregiving, as it highlights the importance of addressing basic physiological needs in order to foster overall well-being and progress toward higher levels of emotional and psychological health.
