What causes feeling cold?
Feeling cold is most often due to actually being in a cold environment. In some cases, such as with infections, you may feel cold despite being quite warm. Other reasons for feeling cold include hypothyroidism, anemia, bacterial or viral infection, and hypothermia.
Common causes of feeling cold
Feeling cold may be caused by a variety of conditions including:
- Bacterial or viral infections
- Blood transfusion
- Body temperature below 96 degrees Fahrenheit (hypothermia)
- Chronic illness, especially when untreated
- Exposure to cold environments
- Hypothyroidism (underactive thyroid)
- Intravenous infusions
- Raynaud’s disease (spasms of small blood vessels of the fingers and toes, reducing blood circulation; has no known cause)
Serious or life-threatening causes of feeling cold
In some cases, feeling cold may be a symptom of a serious or life-threatening condition that should be immediately evaluated in an emergency setting. These include:
- Immersion in freezing water or being exposed to other intense cold temperatures
- Meningitis (infection or inflammation of the sac around the brain and spinal cord) or other serious infections
- Venous thrombosis
Questions for diagnosing the cause of feeling cold
To diagnose your condition, your doctor or licensed health care practitioner will ask you several questions related to your feeling cold including:
- When did you first start feeling cold?
- Where do you feel cold?
- What other symptoms do you have?
- Does anything make you feel better?
- Are you taking any medications?
- Have you recently received a blood transfusion?
What are the potential complications of feeling cold?
The complications of feeling cold depend almost completely on the underlying cause. In most cases, a mild feeling of cold is not associated with serious complications. Feeling very cold, especially due to true hypothermia, can come with life-threatening complications.
Because feeling cold can be due to serious diseases, failure to seek treatment can result in serious complications and permanent damage. Once the underlying cause is diagnosed, it is important for you to follow the treatment plan that you and your health care professional design specifically for you to reduce the risk of potential complications including:
