A primary need is a fundamental requirement for survival and well-being, essential for sustaining life and maintaining physical and emotional health. These needs are universal and include basic necessities such as food, water, shelter, and clothing. They are the most essential and urgent needs that must be met in order for an individual to function and thrive. Primary needs are the foundation upon which all other needs and desires are built, and without their fulfillment, a person’s overall quality of life is greatly diminished.
