Healthy homes
Houses that are warm, dry and well-ventilated help to keep us healthy and well.
How homes affect your health
Your health is affected by your home. How it affects your health includes:
- where it is
- how well it is built
- how warm, dry, well insulated and well-ventilated it is
- how many people live in it
- how much it costs you to live there.
Cold and damp houses can cause illness such as asthma and serious chest infections. Overcrowded homes are linked to the spread of infectious diseases such as rheumatic fever.
Tips to help keep your home warm and healthy
Reduce the risk of you and your whānau getting sick by keeping the indoor temperature of your home at least 18°C where possible, especially in winter.
You should try to keep your home temperature above 20°C if there are:
- pēpi
- tamariki
- elderly people.
Good home insulation is the first place to start in making a warm home — insulation keeps the heat in and lowers heating costs.
The safest, most efficient heaters include:
- heat pumps (especially with thermostats, which help keep costs down)
- electric heaters
- wood burners
- wood pellet burners.
Coal, gas and oil-fired methods of heating are not as safe or efficient. Unflued gas heaters can increase asthma and other respiratory problems and add pollutants to the air. Pollutants include dangerous carbon monoxide — high levels of this can lead to death. Gas braziers and patio heaters should never be used inside.

Burning treated timber or old furniture is dangerous as doing so releases poisonous chemicals into the air.

Consider using a dehumidifier to help warm your house.
- Dehumidifiers are more affordable to run than heat pumps.
- Dry air is less expensive to heat than damp air.
- Keep your dehumidifier in a central location and aim for humidity between 30% and 50%.
- If there is a pēpi in the household, consider keeping a dehumidifier in the room they sleep in.
If you have a heat pump, use the 'auto fan' mode. This keeps it working to maintain the set temperature.

How to keep heat in
- Close your curtains at night to prevent heat loss from the windows.
- Open your curtains during the day to let the sun heat your home.
- If you use an alternative to curtains, like sheets or lavalava, make sure they are snug-fitting to prevent drafts of cold air.
- Check that draughts of cold air are not coming in around your windows and doors.
- Using a draught stopper or a rolled up towel at the bottom of doors can help.
How to keep the damp out
Damp houses are harder to heat and condensation can lead to mould growth.
Condensation is moisture on:
- walls
- windows
- furniture.
Damp and mould affect our lung health and are associated with respiratory tract infections and asthma.
To reduce dampness:
- open doors and windows to air out your house
- dry clothes outside when possible
- reduce condensation — put lids on pots when cooking and use extractors fans in the bathroom and kitchen
- remove condensation from windows with a towel or a condensation squeegee
- pull beds and mattresses away from the walls to let air circulate
- remove any mould with white vinegar or a bleach solution (1 part bleach to 9 parts water)
- use a dehumidifier — they use less energy than a heat pump, and can help your heat pump run better.

You may be eligible for financial and practical assistance to make your home healthier. The Healthy Homes Initiative helps create warm, dry and healthy homes for:

The role of public health
Public health supports other agencies with advice and information about housing quality. They also provide assessments on housing issues related to disease and illness.
