Getting hypothermia in your own home.
It can happen - especially to older people.
Watching out for the elderly and your neighbors is very important in this weather.
The O'Neill Center in Marietta says if a home's temperature drops from 65 to 55 for some reason, their body temperature can also drop very easily.
This can cause hypothermia, even inside the home.
They should also be aware of what medications may be affected by the cold.
Nancy Matheny with the O'Neill Center says seniors have called, worried about their heating bill and how to regulate the temperature in their home.
If you live next to someone who is older or lives alone she says makes sure their lights are turning on and off and that they are moving around.
Also maybe bring over some hot soup, pick up the mail or shovel the sidewalk - something simple that may be difficult for them.
