There is a strong relationship between housing and health:

  • Cold and damp housing contributes to respiratory disease, poor mental health and an exacerbation of chronic conditions. 
  • Overcrowded housing is associated with the spread of infectious diseases such as meningococcal disease. 
  • Housing size, location, structure, and materials also affect occupants' health, as does the way people heat, ventilate and generally use their homes.

New Zealand has very high rates of asthma and respiratory infections – with children, the elderly and those on lower incomes being worse off. New Zealand research into housing and disability shows that inappropriate housing is detrimental to disabled people's independence, social opportunity and safety. 

The WHO recommends that improved housing conditions can save lives, prevent disease, increase quality of life, reduce poverty, and help mitigate climate change. Housing is becoming increasingly important to health in light of urban growth, ageing populations and climate change.
