Temperature Regulation

As we head into the Fall, the weather will begin to cool.  Since our bodies try to maintain a temperature of 37C/98.6F, we will need to acclimatize to the outside.

Older adults have a difficult time with body temperature regulation in both the winter and summer months.  This puts them at risk for hypothermia (in the winter) and hyperthermia (in the summer).

As you age, temperature regulation changes because of:

  • loss of fat under the skin
  • sweat glands decrease in production
  • blood flow to the skin is reduced

When it’s cold outside, don’t forget to:

  • set your thermostat to a minimum of 68-70F/20-21C
  • keep in mind the wind chill factor if you go outside
  • if you do venture outside wear a hat, scarf and gloves
  • drink warm beverages
  • avoid alcohol as it can increase heat loss
  • be cautious if you have an underlying chronic health condition like diabetes, hypothyroidism and cardiovascular diseases as you are more susceptible to hypothermia

And when it’s warm:

  • turn on your air conditioning or visit an air conditioned place
  • keep in mind the heat index
  • stay indoors on hot days
  • if you need to go outdoors, pick a cooler time of day like early morning or evening
  • drink plenty of fluids throughout the day, as your thirst reflex diminishes as you age
  • be cautious if you have existing medical conditions like hypertension, diabetes or Parkinson’s disease as you are susceptible to heat-related injuries

Lastly, certain medications like beta blockers or painkillers can affect older adult’s ability to sweat and regulate temperature. 

Bundle up and stay warm this winter!
