Warm home, healthy family

warm home

Keeping your home cosy and dry this winter is vital. Cold, damp homes are the leading cause of asthma, chest coughs and colds. Insulation and effective heating is the key to a healthy family this winter.

Living in a dry and warm environment is essential for your family’s good health. During the wintertime, dampness, draughts and a lack of insulation make our homes more difficult to heat. Aim to keep the temperature at least 18C throughout your house (room temperatures under 16C are considered harmful).


Insulation is considered to be one of the most important things you can do to keep your home warm and dry. Unfortunately, many older houses in New Zealand were built without insulation. Insulating your ceiling and under the floor is a low-cost option to keep the heat in, and has an added bonus of reducing your heating costs, as the warmth actually stays in your house. Be aware though that if your insulation was installed a long time ago, it may no longer be doing its job properly, so it pays to check how old it is. There is government funding available to help with the costs of insulating and heating your house. Details can be found at www.energywise.govt.nz.


Keeping your house warm and dry also has the added bonus of avoiding mould and dampness which is really unhealthy. If you do have any patches of mould within your house, ensure you remove it quickly using very diluted household bleach. Use extractor fans in your kitchen and bathroom, and dry your clothes outside.


Floor-length curtains (or properly fitted pelmets) will help keep the heat in far more effectively than free-hanging curtains, and pulling your curtains before dusk also make a big differenceto your home’s internal temperature. You should also consider using draught excluders under doors (think: retro draught snake) and draught-proofing strips around windows and doors; as well as double-glazing your windows and insulating your hot water cylinder.


Minimising allergens in your home is another good starting point to keeping your family healthy this winter. Watch carefully for allergy triggers in your children. These could be anything from foods to cigarette smoke, pets to dust mite faeces. If someone in your family does suffer from asthma or has an allergy to dust mite faeces (very common), one of the most effective things to do is use a special bedding cover which provides a barrier to these nasties. Vacumming regularly is essential and having the right type of filter in your vacuum cleaner is very important. Vacuum cleaners with a micro-filter, an S-class filter, or an HEPA (High Efficiency Particulate Air) filter system are the best. Direct sunlight kills dust mites, so hang your washing out in the sun to dry, and air your blankets, duvets and rugs weekly. For children’s soft toys or cuddlies, wash them regularly and either dry in the sun or put them in the deep freeze for 24-48 hours every few weeks, as this will kill the dust mites.
