The home environment we live in plays a huge role in our own health, and the health of our families. Every winter in New Zealand, about 1600 deaths are attributed to people living in cold, damp homes (1). Compared to many other developed countries, New Zealand has much higher rates of people being hospitalised for lung diseases such as asthma (2). Living in cold, damp, mouldy environments places our families at much greater risk of having acute attacks. It is incredibly important that people with such illnesses are not treated just to be sent home to the environment that made them sick.
The World Health Organisation recommends that houses should be insulated so that they are at least 18°C, a minimum temperature where lung (respiratory) illnesses are less likely to occur (3). Unfortunately up to a third of New Zealand’s homes do not meet this minimum standard, with the average temperature in poorer households being 13°C (3,4). This issue is therefore impacting on the health of our poorest communities and needs to be addressed by our government.
It is also clear that insulating homes well would be much more cost-effective for the government. Programmes such as “Warm Up New Zealand” have shown that the savings associated with subsidising insulation and heaters far outweighs the costs by nearly 4 times (cost-benefit ratio of 3.9) (5). The government currently spends $5.5 billion per year on lung (respiratory) illnesses such as asthma, with much of this being preventable (6).
Without a doubt, we strongly believe the Healthy Homes Guarantee Bill (No.2) is a step in the right direction. However there is still much that needs to be done. Together, we can make a difference in ensuring that New Zealand homes are warm and insulated, to improve the health of our children and families.
