Dementia Alert: Alzheimer’s a Cold-Weather Danger


People can lose body heat fast. That’s called hypothermia. Big chills and Alzheimer’s are a dangerous combination. Learn 9 ways to stay safe in cold weather.

Losing too much body heat is a serious problem called hypothermia (hi-po-ther-mee-uh).

Protect people with with dementia from hypothermia during those months when it’s cold outside. Check out these tips on how to stay safe. Share it with your family and friends.

What is hypothermia?

Hypothermia is what happens when your body temperature gets very low. For an older person, a body temperature colder than 95 degrees can cause many health problems, such as a heart attack, kidney problems, liver damage, or worse.

Being outside in the cold, or even being in a very cold house, can lead to hypothermia. You can take steps to lower your chance of getting hypothermia.

Bob’s story

Vermont winters can be very cold. Last December I wanted to save some money so I turned my heat down to 62 degrees.

I didn’t know that would put my health in danger. Luckily, my son Tyler came by to check on me. He saw that I was only wearing a light shirt and that my house was cold.

Ty said I was speaking slowly, shivering, and having trouble walking. He wrapped me in a blanket and called 911. Turns out I had hypothermia. My son’s quick thinking saved my life. Now on cold days, I keep my heat at least at 68 degrees and wear a sweater in the house.

Keep warm inside

Living in a cold house, apartment, or other building can cause hypothermia. People who are sick may have special problems keeping warm. Do not let it get too cold inside and dress warmly.

9 Tips for keeping warm inside:

  1. Set your heat at 68 degrees or higher.
  2. To save on heating bills, close off rooms you are not using.
  3. To keep warm at home, wear long johns under your clothes.
  4. Throw a blanket over your legs.
  5. Wear socks and slippers.
  6. When you go to sleep, wear long johns under your pajamas, and use extra covers.
  7. Wear a cap or hat.
  8. Ask family or friends to check on you during cold weather.
  9. Bundle up on windy, cool days

Stay warm outside

A heavy wind can quickly lower your body temperature. Check the weather forecast for windy and cold days. On those days, try to stay inside or in a warm place. If you have to go out, wear warm clothes.

Tips for bundling up:

  1. Dress for the weather if you have to go out on chilly, cold, or damp days.
  2. Wear loose layers of clothing. The air between the layers helps to keep you warm.
  3. Put on a hat and scarf. You lose a lot of body heat when your head and neck are uncovered.
  4. Wear a waterproof coat or jacket if it’s snowy.

Ask Your Doctor

Talk with your doctor about how to stay safe in cold weather. Some illnesses may make it harder for your body to stay warm. Taking some medicines and not being active also can affect body heat. Your doctor can help you find ways to prevent hypothermia.

Tips for talking with your doctor about hypothermia:

  1. Ask your doctor about signs of hypothermia.
  2. Talk to your doctor about any health problems (such as diabetes) and medicines that can make hypothermia a special problem for you.
  3. Ask about safe ways to stay active even when it’s cold outside.

Warning signs of hypothermia

Sometimes it is hard to tell if a person has hypothermia. Look for clues.

  • Is the house very cold?
  • Is the person not dressed for cold weather?
  • Is the person speaking slower than normal?
  • Is the person having trouble keeping his or her balance?

Watch for the signs of hypothermia in yourself, too. You might become confused if your body temperature gets very low. Talk to your family and friends about the warning signs so they can look out for you.

Early signs of hypothermia:

  • cold feet and hands
  • puffy or swolen face
  • pale skin
  • shivering
  • slower than normal speech or slurring of words
  • acting sleepy
  • being angry or confused

Later signs of hypothermia:

  • moving slowly, trouble walking, or being clumsy
  • stiff and jerky arm or leg movements
  • slow heartbeat
  • slow, shallow breathing
  • blacking out or losing consciousness

Calling 911

Call 911 right away if you think someone has warning signs of hypothermia.

Tips for what to do after you call 911

  • Wrap the person in a warm blanket.
  • Do not rub the person’s legs or arms.
  • Do not try to warm the person in a bath.
  • Do not use a heating pad.


Your questions answered:

Q. What health problems can make it hard for my body to stay warm?

So one to prevent the hypothermia is to judge the symptoms before it happens.

Cold effects thinking and performance.That's why offices have to be a certain temperature according to H&Saftey Rules.A person with Dementia is already impaired and cognitively challenged.Sitting in a cold room will make it even more difficult and aggravate this condition for the person.My father sometimes is taking clothes off when he should be putting them on.Strangely people who get hypothermia are also known to do this.Our house is warm.
