The Effects of a Cold Home on your Family’s Health

20 July 2020

A warmer, drier home makes it harder for germs to spread. That is the vital point when it comes to New Zealand’s predominantly cold and damp housing that results in a reported 1600 deaths every winter.

“The houses of the 48% of Kiwis who are shivering are extremely cold. Research published in 2010 by the Building Research Association (Branz) found that the average evening temperature of New Zealand living rooms during the winter was 17.8°C – below the World Health Organisation’s recommended minimum of 18°C. But some were a chilly 10°C.”

‘1600 deaths attributed to cold houses each winter in New Zealand’ – Ruth Nicol,

How does a cold home affect health?

The World Health Organisation recommends that our homes be at a minimum temperature of 18°C, or 20°C for homes with young children, elderly or ill people.

Effects of living in a damp house that is both cold and mouldy poses the following risks:

  • Increased risk of respiratory infections (when indoor temperatures are under 16°C.)
  • Stress on the cardiovascular system (when indoor temperatures are under 12°C).
  • Increased risk of the onset of asthma.
  • Asthma symptoms are likely to worsen.
  • Dampness and mould are associated with respiratory tract infections and bronchitis.
