What does the 'physiological' level in Maslow's hierarchy encompass?

The physiological level in Maslow's hierarchy encompasses basic needs that are essential for human survival and functioning. This includes fundamental requirements such as hunger, thirst, sleep, and the need for shelter. According to Maslow, these needs are the most basic and must be satisfied before an individual can address higher-level needs such as safety, social interaction, esteem, or self-actualization.

The importance of the physiological level lies in its foundational role; without meeting these critical needs, individuals may struggle to focus on other aspects of their lives, such as relationships or personal development. This hierarchy underscores the idea that without the fulfillment of basic physiological needs, higher-level psychological and self-fulfillment needs cannot be adequately pursued.
