Almost everyone knows about winter dangers such as broken bones from falls on ice or breathing problems caused by cold air. But, cold weather is very risky for older people. The winter chill can also lower the temperature inside your body. That can be deadly if not treated quickly. This drop in body temperature, often caused by staying in a cool place for too long is called hypothermia (hi-po-ther-mee-uh).
A body temperature below 96° F may seem like just a couple of degrees below the body’s normal temperature of 98.6° F. But, it can be dangerous. It may cause an irregular heartbeat leading to heart problems and death.
What To Look For
When you think about being cold, you probably think of shivering. That is one thing the body does to stay warm when it gets cold. Muscles shiver in response to messages sent by the nerves. Shivering increases muscle cell activity that, in turn, makes heat. But, shivering alone does not mean hypothermia.
So, how can you tell if someone has hypothermia? It can be tricky because some older people may not want to complain. They may not even be aware of how cold it is. Look for the “umbles” — stumbles, mumbles, fumbles, and grumbles — these show that the cold is affecting how well a person’s muscles and nerves work. Watch for:
What Should I Do?
If you think someone could have hypothermia, take his or her temperature with a thermometer. Make sure you shake the thermometer so it starts below its lowest point. If the temperature doesn’t rise above 96° F, call for emergency help. In many areas that means calling 911.
The only way to tell for sure that someone has hypothermia is to use a special thermometer that can read very low body temperatures. Most hospitals have such thermometers. The person must be seen by a doctor. If possible, the doctor should know about hypothermia and work in a well-equipped hospital emergency room. There, the doctors will warm the person’s body from inside out. For example, they may give the person warm fluids directly into a vein using an I.V. Whether the person gets better depends on how long he or she was exposed to the cold and his or her general health.
While you are waiting for help to arrive, keep the person warm and dry. Move him or her to a warmer place, if possible. Wrap the person in blankets, towels, coats — whatever is handy. Even your own body warmth will help. Lie close, but be gentle. You may be tempted to rub the person’s arms and legs. This can make the problem worse. The skin of an older person may be thinner and more easily torn than the skin of someone younger.
What Things Put Me At Risk?
There are some things that put any older person at risk for hypothermia. What can you do?
Staying Warm Inside and Out
Maybe you already knew that your health, your age, what you eat or drink, even your clothes can make it hard for you to stay warm enough wherever you are. What you might not realize is that people can also get cold enough inside a building to get very sick. In fact, hypothermia can even happen to someone in a nursing home or group facility if the rooms are not kept warm enough. People living there who are already sick may have special problems keeping warm. If someone you know is in a group facility, pay attention to the inside temperature there and to whether that person is dressed warmly enough.
Homes or apartments that are not heated enough, even with a temperature of 60° F to 65° F, can lead to illness. This is a special problem if you live alone because there is no one else to comment on the chilliness of the house or to notice if you are having symptoms of hypothermia. Set your thermostat for at least 68° F to 70° F. If a power outage leaves you without heat, try to stay with a relative or friend.
Avoid using space heaters if your home seems cold or if you want to keep the thermostat set lower to keep your heating costs down. Some types are fire hazards, and others can cause carbon monoxide poisoning. The Consumer Product Safety Commission has information on the use of space heaters, but here are a few things to remember:
Don’t forget that you need to stay warm when it’s cold outside. Remember that this means knowing if weather forecasts are for very cold temperatures or for windy and cold weather. You lose more body heat on a windy day than a calm day. Weather forecasters call this the wind-chill factor. They often suggest, even when the outside temperature itself is not very low, that the wind-chill factor is cold enough for people to stay indoors. If you must go out, dress correctly. Be sure to wear a hat and gloves, as well as warm clothes.
Is There Help for My Heating Bills?
Sometimes older people need help making sure their home will keep them warm enough. Some help is available. If your home doesn’t have enough insulation, contact your state or local energy agency or the local power or gas company. They can give you information about weatherizing your home. This can help keep the heating bills down. You might also think about only heating the rooms you use in the house. For example, shut the heating vents and doors to any bedrooms not being used. Keep the door to the basement closed.
If you have a limited income, you may qualify for help paying your heating bill. State and local energy agencies, or gas and electric companies, may have special programs. Another possible source of help is the Low Income Home Energy Assistance Program (LIHEAP). This program supports some people with small incomes who need help paying their heating and cooling bills. Your local area agency on aging, senior center, or community action agency may have information on programs such as these.
Are you worried that your landlord may want to cut off the gas or electricity in cold weather if you cannot pay a utility bill? Many states and cities now have laws to protect you, at least until other plans are made. Do not wait for winter to find out about these programs. Check with your local government about the laws that may apply where you live.
