<P> Physiological needs are the physical requirements for human survival . If these requirements are not met, the human body cannot function properly and will ultimately fail . Physiological needs are thought to be the most important; they should be met first . This is the first and basic need on the hierarchy of needs . Without them, the other needs cannot follow up . </P> <P> Physiological needs include: </P> <Ul> <Li> Breathing </Li> <Li> Water </Li> <Li> Food </Li> <Li> Sleep </Li> <Li> Clothing </Li> <Li> Shelter </Li> </Ul> <P> Once a person's physiological needs are relatively satisfied, their safety needs take precedence and dominate behavior . In the absence of physical safety--due to war, natural disaster, family violence, childhood abuse, etc.--people may (re -) experience post-traumatic stress disorder or transgenerational trauma . In the absence of economic safety--due to economic crisis and lack of work opportunities--these safety needs manifest themselves in ways such as a preference for job security, grievance procedures for protecting the individual from unilateral authority, savings accounts, insurance policies, disability accommodations, etc . This level is more likely to predominate in children as they generally have a greater need to feel safe . Safety and security needs are about keeping us safe from harm . These include shelter, job security, health, and safe environments . If a person does not feel safe in an environment, they will seek to find safety before they attempt to meet any higher level of survival, but the need for safety is not as important as basic physiological needs . </P>
