Three Ways to Stay Warm During a Power Outage
Cold weather during an outage can make things very uncomfortable, especially for families with young children or elderly members.
Here are three simple ways to stay warm:
1. Use Multiple Blankets
Wrap yourself in two or more thick blankets.
Layer the blankets around your waist or under your arms to trap heat more effectively.
Avoid overheating, as sweating can make you colder later.
2. Wear Gloves and Thick Footwear
Use gloves or place your hands inside your pockets to retain warmth.
Wear insulated or fluffy shoes to keep your feet warm.
Even inside the house, warm clothing helps conserve body heat.
3. Light Candles or Use a Fireplace
Use candles to provide a bit of warmth in closed spaces.
If available, gather around a fireplace or build a safe outdoor fire.
Make sure there’s proper ventilation to avoid carbon monoxide buildup indoors.
