Cold weather can cause more than shivering
It affects every organ system, says UCI Health emergency medicine expert
IN THE NEWS: Cold weather isn’t just unpleasant — it can be dangerous.
UCI Health emergency medicine physician Dr. Isabel Algaze Gonzalez spoke with the New York Times about its effect on the body.
“Cold affects every organ system. It doesn’t just make you shiver, it makes your heart work harder.”
The extra strain is especially dangerous for anyone with preexisting heart issues.
Within 20 minutes of exposure, cold temperatures can raise one’s blood pressure. Cold weather has been linked to increased risk for heart attack, stroke and kidney injury. Strenuous activities, such as clearing snow off a path, are a common tipping point.
Algaze Gonzalez specializes in emergency medicine and is trained in primary hyperbaric medicine, avalanche medicine, dive medicine, mountain medicine and coordinating emergency medical teams.
Her clinical interests include wilderness medicine, hyperbaric medicine, dive medicine, expedition medicine, global medicine and humanitarian aid.
An assistant professor of emergency medicine at the UC Irvine School of Medicine, her current research interests are in the treatment of box jellyfish stings and the relationship between acute mountain sickness and cognitive impairment.
