Cold Hands and Poor Circulation: What Is the Connection?

Cold is able to come through suddenly when the blood flow to your hands decreases. Your fingers are at the periphery of your circulatory systems, so even minor fluctuations in blood pressure or vessel caliber or cardiac output can leave you feeling disproportionately chilly in your hands. This is not just about cold weather — it tends to reflect how effective your body is at keeping extremities warm.

Sitting for long periods, or poor posture, can hamper the flow of blood to your arms and hands. You may be squeezing the blood vessels without being aware of it, by crossing your arms tightly, propping yourself up with your elbow or simply sitting too long. Over time, this can cause your hands to feel cold more often while at rest.

And in some cases, cold hands may be a warning sign of health issues, such as anemia. Diseases such as narrowed arteries (atherosclerosis), heart failure and a low blood pressure can reduce the flow of blood. Even smokers may have colder hands because of narrowed blood vessels. Poor circulation may be to blame if your hands are always cold, even if you have on gloves and feel that your body is warm.
