How to Stay Warm During a Winter Power Outage

By Published May 13, 2026

A winter power outage is different from a normal blackout. Losing the lights is annoying. Losing heat when the temperature is dropping can become dangerous fast.

The mistake a lot of people make is thinking they can just “bundle up and wait it out.” Sometimes that works. Sometimes it does not. If the outage lasts long enough, your home can keep getting colder, pipes can freeze, phones can die, food can become harder to manage, and people may start using unsafe heat sources out of desperation.

That is where winter outages get risky.

Staying warm during a winter power outage is not about acting tough. It is about keeping body heat in, using your home wisely, avoiding carbon monoxide, protecting vulnerable people, and knowing when it is time to leave for a safer place.

Start by Trapping the Heat You Already Have

When the power goes out in winter, your first job is not to create more heat. Your first job is to keep the remaining heat from escaping.

Close exterior doors quickly. Do not go in and out of the house unless you truly need to. Every trip outside lets warm air escape and cold air push in.

Close curtains and blinds, especially after dark. Windows lose heat fast, and covering them helps reduce drafts. If you have heavy curtains, use them. If you do not, blankets, towels, or even cardboard can help block cold air around drafty windows.

Put towels at the bottom of doors where cold air leaks in. If you have weather stripping already installed, great. If not, this is where rolled-up towels actually earn their keep.

The goal is simple: slow the heat loss before the house becomes uncomfortable.

Choose One Warm Room

Do not try to keep the whole house comfortable during a long winter outage.

Pick one main room where everyone can gather. A smaller interior room is usually easier to keep warm than a large open living room with lots of windows. Bedrooms, dens, or interior rooms may work better depending on your home.

Close doors to unused rooms. If you have blankets, towels, or draft stoppers, use them around the door of the room you are staying in.

Move supplies into that room early:

Blankets
Sleeping bags
Flashlights
Phone chargers and power banks
Water
Snacks
Medication
Pet supplies
Warm clothes

Do this before the house is freezing. Moving around in the dark and cold later is miserable and unnecessary.

Dress in Layers, Not Just One Heavy Coat

Layering works better than relying on one bulky item.

Start with a base layer that stays close to your skin. Add a warmer middle layer like fleece, wool, or a sweatshirt. Then add an outer layer if needed. Loose layers can trap warm air better than one tight layer.

Pay attention to your head, hands, and feet. Cold feet make everything feel worse. Wear warm socks, slippers, shoes, or boots inside if the floors are cold. Wear a hat indoors if needed. It may feel silly, but staying warm beats pretending you are above it.

Avoid getting sweaty. Sweat makes clothing damp, and damp clothing can make you colder. If you start overheating while moving supplies or shoveling snow, remove a layer before you sweat too much.

This is one of those boring details that actually matters.

Use Blankets the Smart Way

Blankets are not just for beds during a winter outage.

Use them to create warmth zones. Sit under blankets together. Put a blanket over your lap. Add one under you if you are sitting on a cold couch, chair, or floor. Cold surfaces can pull heat away from your body.

Sleeping bags are even better if you have them. They are designed to hold body heat in.

If several people are in one room, shared body heat can help. That does not mean everyone needs to be miserable and cramped, but keeping the household together in one warm area usually works better than spreading out across cold rooms.

For babies, older adults, and anyone with health issues, do not rely on “they seem fine.” Check them often.

Block Drafts Around Windows and Doors

Drafts can make a room feel much colder than the actual temperature.

Check around windows, doors, fireplaces, vents, and floor gaps. Use towels, blankets, painter’s tape, plastic sheeting, cardboard, or draft stoppers if you have them.

Do not block anything that is needed for safe ventilation if you are using an approved heat source that requires airflow. That matters. Trying to seal everything while using unsafe combustion heat is how people get into carbon monoxide trouble.

But if you are just trying to hold warmth in a room with no combustion heat source running, blocking drafts can help a lot.

Never Use a Gas Stove or Oven for Heat

This is where people get hurt.

Do not use a gas stove or oven to heat your home. Do not bring a charcoal grill inside. Do not use a camping stove indoors. Do not run a propane heater indoors unless it is specifically rated for indoor use and you follow the manufacturer’s safety directions exactly.

The CDC warns that fuel-burning devices can create carbon monoxide, a gas you cannot see or smell, and says never to use generators, charcoal grills, camp stoves, or similar devices inside homes, garages, tents, or campers. The CDC also specifically warns not to use a gas range or oven to heat a home.

This is not overcautious advice. Carbon monoxide poisoning can kill people while they sleep.

If your only heat plan involves bringing outdoor equipment indoors, you do not have a heat plan. You have a hazard.

Be Extremely Careful With Generators

A generator can be useful during a winter outage, but only if it is used correctly.

Never run a generator inside your home, basement, garage, porch, shed, or any partly enclosed area. The CDC says generators should be kept at least 20 feet away from windows, doors, and vents.

That includes the garage with the door open. That is still not safe.

Use heavy-duty outdoor-rated extension cords that are in good condition. Keep cords away from water, snow buildup, and places where people can trip.

Do not plug a generator directly into your home’s wiring unless you have the proper transfer equipment installed by a qualified professional. Backfeeding power can be dangerous for utility workers and your home.

Also, every home using a generator should have working carbon monoxide alarms with battery backup.

Use Safe Backup Heat Only

If you have a fireplace, wood stove, or other backup heat source, use it only if it is properly installed, vented, maintained, and safe to operate.

A fireplace that has not been cleaned or inspected can create fire and smoke risks. A kerosene or propane heater that is not approved for indoor use can create carbon monoxide danger. A heater used too close to curtains, bedding, furniture, or clothing can start a fire.

If you use an indoor-safe space heater powered by a generator or battery system, keep it away from anything flammable. Do not place it near blankets, bedding, laundry, paper, or furniture.

A safe heat source still needs common sense.

Protect Babies, Older Adults, and Vulnerable People First

Cold affects people differently.

Babies, older adults, people with medical conditions, people with limited mobility, and anyone who cannot easily communicate discomfort may be at higher risk during a winter outage.

Check them often. Make sure they have dry clothing, warm layers, blankets, food, water, and necessary medicine.

Do not assume someone is fine because they are quiet. Cold can make people tired, confused, or less responsive.

If your home temperature keeps dropping and someone vulnerable is in the house, do not wait until it is an emergency. Start planning where to go while roads are still passable.

Keep Pets Warm Too

Pets need a winter outage plan.

Bring outdoor pets inside before conditions become dangerous. Give pets a warm place away from drafts and cold floors. Use blankets or pet beds if available.

Small dogs, short-haired pets, puppies, senior animals, and sick pets may get cold faster. If the floor is cold, get them off the floor. Put bedding in the warm room with the family.

Make sure pets have water that is not frozen and enough food. Keep leashes, carriers, medication, and vaccination records ready in case you need to leave.

A pet is not “built for it” just because it has fur. That is lazy thinking.

Keep Drinking Water and Food Nearby

Cold weather can make people forget to drink water. That is a mistake.

Keep water in your warm room so you are not constantly opening doors or walking through cold parts of the house. Eat simple food that does not require cooking if your normal cooking setup is down.

Good outage food includes:

Peanut butter
Crackers
Canned tuna or chicken
Granola bars
Trail mix
Applesauce
Cereal
Shelf-stable milk
Ready-to-eat soups or meals if you can heat them safely

If you cannot heat food safely, do not improvise with outdoor cooking equipment inside the house.

Warm drinks can help you feel better, but only make them if you have a safe way to heat water.

Protect Your Pipes If the Outage May Last

Winter power outages can create plumbing problems, especially if the house gets cold for a long time.

Open cabinet doors under sinks so warmer room air can reach pipes. This matters most for sinks on exterior walls.

Letting faucets drip slightly may help reduce freezing risk in some situations. Focus on faucets served by exposed or vulnerable pipes.

If you expect the home to become dangerously cold or you need to leave for an extended time, you may need to know how to shut off water to the house. That is something to learn before a storm, not while freezing water is already causing damage.

Pipes are not the top priority over people, but a little prevention can save a huge mess.

Use Your Car Carefully If You Need Warmth

A vehicle can provide heat, but it can also become dangerous if used carelessly.

If you use a car for warmth, it must be outside, never in a garage. Make sure the exhaust pipe is clear of snow, mud, leaves, or debris. Carbon monoxide can build up if exhaust is blocked or if the vehicle is in an enclosed space.

Do not sit in the car for hours with no plan. Use it briefly if needed, conserve fuel, and keep ventilation in mind.

If roads are unsafe, do not drive around just to warm up. But if your home is becoming dangerously cold and you have a safe route to a warmer location, leaving may be the smarter choice.

Watch for Signs of Hypothermia

Hypothermia happens when the body loses heat faster than it can produce it. It can become serious.

Warning signs may include shivering, confusion, exhaustion, slurred speech, clumsiness, drowsiness, weak pulse, or shallow breathing. In babies, warning signs can include cold skin, low energy, or unusual behavior.

Do not ignore confusion or extreme sleepiness in a cold house. That can be a danger sign, not just someone being tired.

If someone may have hypothermia, get medical help. Move them to a warmer place if you can do so safely. Remove wet clothing and warm the center of the body with blankets or dry layers.

Know When to Leave

This is the part people hate because it feels like admitting defeat.

Leaving is not failure. Staying in an unsafe cold house because of pride is stupid.

You should consider leaving if:

The indoor temperature keeps dropping
You have babies, older adults, or medically vulnerable people at home
You do not have safe heat
Your pipes are freezing and conditions are worsening
Phones are dying and you cannot get updates
You are running out of safe food or water
Local officials recommend sheltering elsewhere
You feel yourself making risky choices to stay warm

Go to a friend’s house, family member’s home, hotel, warming center, public shelter, or another safe heated place if available.

The right time to leave is before everyone is exhausted, cold, and desperate.

What Not to Do During a Winter Power Outage

Do not use a gas stove or oven to heat the house.

Do not run a generator indoors, in a garage, or near windows.

Do not bring charcoal grills or camping stoves inside.

Do not use outdoor propane heaters indoors.

Do not leave candles unattended.

Do not ignore carbon monoxide alarms.

Do not open exterior doors constantly.

Do not let pets stay outside in dangerous cold.

Do not wait too long to leave if the home becomes unsafe.

Do not assume the outage will be short.

Most winter outage disasters come from bad heat choices, not just cold weather.

The Bottom Line

A winter power outage is not the time to improvise with dangerous heat sources.

The safest plan is to trap the heat you already have, gather everyone into one warm room, dress in layers, block drafts, conserve phone battery, use only safe heating methods, and leave if the house becomes too cold.

The people who handle winter outages best are not the toughest. They are the ones who prepare early and avoid dumb risks.

Cold is serious. Carbon monoxide is serious. Fire risk is serious.

Stay warm, but stay smart.
