The short version: Winter brings three big dangers to a senior’s home: heating fires, carbon monoxide, and cold itself. Space heaters cause most home heating fire deaths, so use them by strict rules or not at all. Put working carbon monoxide alarms on every level, keep the home warm enough (68 to 70°F, because older bodies lose heat fast), seal drafts, protect the pipes, and arrange snow and ice removal at the entrance before the first storm.
Why winter is riskier for an older adult
The cold season quietly stacks hazards that hit seniors harder than anyone, so a little preparation before it arrives pays off.
Heating equipment is a leading cause of home fires, and those fires peak in December, January, and February.1 On top of that, carbon monoxide risk rises whenever furnaces and heaters run, and an older body loses heat faster, so a home that feels merely cool can turn dangerous. The steps below handle all three, and most cost little or nothing.
This is the winter companion to our heat safety for seniors guide, and part of the home safety checklist.
Service the heat before the cold
Start with the system that will run for months. Get ahead of it.
Have the heat pump or furnace checked and the filter changed before the first cold snap, so it runs safely and efficiently all season. A clogged filter makes the system strain, wastes money, and can be a breakdown or fire risk. If a room is always cold, our ductless mini-split guide covers an efficient way to warm one space.
Space heaters: the number-one winter fire risk
This is the single most important winter safety point, because space heaters are the deadliest common heating choice.
Most home heating fire deaths, about 81%, involve a space heater or other heating equipment, and more than half of those deaths happen when the heater is placed too close to something that can burn.1 Portable heaters alone cause roughly 1,700 fires and 80 deaths a year.2
If a space heater is used, the rules are strict: keep at least three feet of clear space around it, away from furniture, curtains, bedding, and clothing. Plug it directly into a wall outlet, never a power strip or extension cord, which can overheat. Use only a safety-tested model (UL or ETL listed) with automatic shut-off and tip-over protection. Never run it unattended or overnight while sleeping, and never use it to dry clothes. When in doubt, turn it off.
Carbon monoxide: the invisible danger
Every appliance that burns fuel can produce carbon monoxide, and heating season is when it matters most. You cannot see or smell it.
Put a working carbon monoxide alarm on every level of the home and near sleeping areas, test them, and keep the batteries fresh.4 Have the furnace, any chimney, and the vents checked so combustion gases go outside, not into the house.
Never run a generator, grill, or car engine in a garage or any enclosed space, even with the door open. Know the symptoms of carbon monoxide poisoning, headache, dizziness, nausea, and confusion, and if an alarm sounds or symptoms appear, get everyone outside into fresh air and call 911.4 Our smart smoke and CO detector guide covers alarms that also alert family.
Keep the home warm enough
This one runs opposite to a fixed-income instinct to turn the heat down, and it is a genuine health issue.
An older body loses heat faster and can develop hypothermia in a home that feels only cool to a younger person.3 Keep the home warm, generally around 68 to 70°F, and do not let a senior underheat to save money.
Watch for hypothermia: shivering, cold or pale skin, confusion, drowsiness, and slurred speech. It can come on slowly indoors. If you suspect it, warm the person gradually and call for help.5 Check on older adults living alone during cold spells, and if heating cost is the barrier, our guide to paying for home upgrades covers energy assistance.
Seal drafts and save on heat
Sealing the home warmer helps comfort, safety, and the heating bill at once.
Weatherstrip doors and windows, seal gaps where cold air leaks in, and add insulation where it is thin. This keeps the whole home warmer, reduces the temptation to underheat, and lowers bills, which matters on a fixed income. Income-qualified households may get this done free through the federal Weatherization Assistance Program; see our funding guide.
Protect the pipes
A burst pipe in a freeze can flood a home and displace a senior at the worst time of year. Prevent it.
Insulate exposed pipes in unheated spaces like basements, crawl spaces, and garages. During a hard freeze, let a faucet drip slightly to keep water moving, and open cabinet doors so warm air reaches pipes under sinks. Most important, know where the main water shut-off is, so a burst pipe can be stopped in seconds rather than minutes.
The entrance and the ice
Winter turns the walk to the door into one of the year’s biggest fall hazards. Plan for it before the first storm.
Arrange in advance who will shovel and salt the walk, steps, and ramp, and do not let an older adult with heart or balance problems clear snow themselves, since it strains the heart and invites a fall. Keep ice-melt and a sturdy shovel by the door, add bright motion lighting, and use slip-resistant surfaces. A cleared, lit, well-railed entrance is the goal; see our accessible entrance and stair safety guides.
Have a cold-weather emergency plan
Winter storms cause power outages, and a senior without heat is in real danger. Be ready before it happens.
Keep a safe backup heat plan, extra blankets, a flashlight and a charged phone with a battery pack, and stock a few days of food and any medication. Pick one room to keep warm if the power fails, and set a check-in schedule with family. Our hurricane prep guide covers power-outage planning that applies to winter storms too.
