Why do I feel cold when not outside?

* Hypothermia: Occurs when the body's internal temperature drops too low. Symptoms include shivering, confusion, pale or blue skin, and weakness. Seek medical attention if you think you have hypothermia.

* Anemia: Low red blood cell count. Red blood cells carry oxygen to your tissues, and a lack of them can make you feel cold. Symptoms include fatigue, weakness, dizziness, and shortness of breath.

* Hypothyroidism: A condition in which your thyroid gland does not produce enough of certain hormones. Symptoms include tiredness, weight gain, dry skin, and constipation.

* Vitamin or mineral deficiencies: Certain vitamin and mineral deficiencies can also lead to cold intolerance. For example, a vitamin B12 deficiency can cause fatigue, weakness, and cold intolerance.

* Raynaud's disease: A condition that causes your fingers, toes, and other parts of your body to become pale, numb, and cold when exposed to cold temperatures.

* Other medical conditions: Certain medical conditions, such as diabetes and heart disease, can also cause cold intolerance. If you have a chronic medical condition, talk to your doctor about whether it could be causing your cold intolerance.
