Cold weather and power outages: getting through winter together

Updated Well Day Media Editorial Team
The short answerCold claims more lives than heat, and the most vulnerable are older, sick and isolated people. During power outages, agreements with neighbors and family help: who checks on whom, where to warm up and how to stay in touch. The biggest dangers are hypothermia and carbon monoxide poisoning from generators and stoves used indoors.

Key points

Cold is a silent risk

A large study of more than 74 million deaths in 13 countries, including the U.S., found that cold is linked to more deaths than heat (Gasparrini et al., 2015). Cold raises blood pressure and strains the heart and lungs. Older adults, people with chronic illness and those who live alone are most at risk. Winter storms such as the February 2021 Texas outage showed how fast cold homes become dangerous.

Why connections matter

A meta-analysis of 148 studies found that strong social relationships are linked to about 50% higher odds of survival (Holt-Lunstad et al., 2010). In a crisis of cold, darkness and no phone service, that difference becomes very practical: someone notices you are unwell, brings you a hot drink or helps you get to a warming center.

Plan ahead

With family

What not to do

A review of carbon monoxide poisoning after disasters and power outages found the main causes were generators run indoors, in garages or basements, and cooking devices used for heat (Iqbal et al., 2012).

Small actions that matter

Steps like these protect others’ health, and, as research on kindness suggests, support your own well-being too.

Frequently asked questions

How do I help an older neighbor I do not know?

Start small: knock, introduce yourself and leave your phone number. Offer to check in during storms. Many people find it hard to ask for help first.

What should I have on hand for a long outage?

Water, food that needs no cooking, a few weeks of medications, flashlights, batteries, a power bank, warm clothes, sleeping bags and a paper list of phone numbers.

Where can I warm up if my home is too cold?

Warming centers, libraries, community centers, or the homes of family or neighbors with heat. Call 211 to find local resources.
