Physiological Needs[edit]

Are you getting enough restful sleep?

We all share simple requirements for sustaining life and health. Our physiological needs are the minimal requirements of survival. These physiological needs include:

  • Air—oxygen within a particular range of pressure, concentration, and purity is vital to survival. Lack of oxygen kills by asphyxiation within minutes.
  • Water—access to adequate safe drinking water, 8 cups of water per person per day, is a human need. Lack of water kills by dehydration within days.
  • Food—Adequate calories, meeting certain minimum nutritional requirements are required to sustain life. Lack of food kills by starvation within days or weeks.
  • Shelter—protection from extremes of heat, cold, intense sun, prolonged precipitation, or other exposure that can lead to hypothermia or hyperthermia. Protective clothing may fill this need in certain environments.
  • Sanitation—isolation or protection from toxins and pathogens—this includes removal of human wastes, basic cleansing, and protections from harmful infectious agents such as parasites, bacteria, and viruses.
  • Sleep—adequate sleep of sufficient depth. Research is incomplete or disputed, and sleep needs can vary by age and among individuals, however approximately 7-8 hours of uninterrupted sleep each night is a rough guideline.
  • Touch—Active touch, perhaps as a caring caress, is essential to the growth and healthy development of humans. [1]
  • Space—People require some amount of personal space, indoor living space, and outdoor space, to avoid overcrowding. The particular amount required is difficult to define.[2] Several benefits to urban space have been established.
