With temperatures so cold Thursday morning, it's not just an inconvenience, it can be dangerous.
Local health officials warn if you don't bundle up, you could end up in the emergency room at the hospital.
They say hypothermia is one concern. That's when your body loses heat faster than it can produce. Frostbite also happens when exposed skin is damaged.
Rick Knochel, a nurse practitioner at Blessing Hospital, said both are dangerous, especially for kids and seniors. He adds you need to be on the lookout for certain things.
"As far as like Hypothermia, definitely if you are getting confusion, pain or if you're getting real weak, those things you need to come in and see us, as far as frostbite if you are getting extremities, cold white in color, those types of things that's when we get concerned," Knochel said.
He adds cold temps can also be especially dangerous for people with conditions including asthma.
"The biggest thing with cold temperatures is to cover, the areas where you are gonna have those problems, so if you think of your face or extremities those are the areas that are gonna get cold first because there are poor circulation to those area, so you definitely wanna be covering those areas," Knochel said.
The best way to protect yourself is make sure you are bundled up and all skin is covered.
He adds if you notice your limbs turning or if you feel extremely weak, you should seek medical attention.
