Hypothermia is a dangerous drop in body temperature that may result in long term, serious health problems such as a heart attack, kidney or liver damage, or death.

Older adults are especially vulnerable to hypothermia because their body’s response to cold is often diminished by underlying medical conditions such as diabetes. Certain medications, including over-the-counter cold remedies, can also affect the body’s response to temperature.

According to the National Institute on Aging, hypothermia is generally defined as having a core body temperature of 95 degrees Fahrenheit or lower. It can occur when the outside environment gets too cold or the body’s heat production decreases. Hypothermia can develop in older adults even after relatively short exposure to cold weather or a small drop in temperature. Recent CDC data shows that nearly two-thirds (63 percent) of the 2,000 weather related deaths for all ages between 2006-10 were due to exposure to excessive cold, hypothermia, or both. Between 1999 and 2002, 49 percent of those who died from hypothermia were aged 65 or older, 67 percent were male. Continue reading

With much of the country feeling the “polar vortex” and some of the coldest temperatures seen in 20 years in some places, reporters may be called upon to write about health – and death – in cold weather.

Hypothermia is the unintentional lowering of the body’s core temperature below 95º F. According to the Centers for Disease Control and Prevention, common risk factors for hypothermia include exposure to cold while under the influence of alcohol or drugs, altered mental status and immersion in cold water. Other factors can include advanced age, chronic medical conditions, substance abuse and homelessness.

The CDC has some winter weather health and safety tips to help people protect themselves from frostbite, hypothermia, carbon monoxide poisoning, chainsaw mishaps and more. Here are some other general resources: Continue reading
