Know that changes in your body that come with aging can make it harder for you to be aware of getting cold.
Wear several layers of loose clothing when it’s cold. The layers will trap warm air between them. Don’t wear tight clothing because it can keep your blood from flowing freely. This can lead to loss of body heat.
Ask your doctor how the medicines you are taking affect body heat. Some medicines used by older people can increase the risk of accidental hypothermia. These include drugs used to treat anxiety, depression, or nausea. Some over-the-counter cold remedies can also cause problems.
When the temperature has dropped, drink alcohol moderately, if at all. Alcoholic drinks can make you lose body heat.
Make sure you eat enough food to keep up your weight. If you don’t eat well, you might have less fat under your skin. Body fat helps you to stay warm.
Some illnesses may make it harder for your body to stay warm. These include problems with your body’s hormone system such as low thyroid hormone (hypothyroidism), health problems that keep blood from flowing normally (like diabetes), and some skin problems where your body loses more heat than normal.
