The Connection Between Cold Hands and Feet, and Your Thyroid


Cold feet and hands can be linked to a number of different health issues including hypothyroidism. 

Studies show that having poor circulation can also lead to heart problems.

The thyroid gland is a very important gland in the body. It controls the basal metabolic rate, or BMR. The BMR can be defined as the minimal rate of energy the body expends, or the rate at which the cells are able to make energy or heat. When the thyroid is working properly, the body will stay at the appropriate temperature—98.6 degrees Fahrenheit. Although the body may fluctuate up to one degree daily, if your temperature typically remains below 98.6 degrees, and you are sensitive to the cold, this may indicate a problem with your thyroid. 

According to, “The thyroid hormone affects the cardiac contractility along with components such as blood pressure, rhythm disturbances, and more. All of these are of great importance, but one that stands out is the cardiac contractility. Cardiac contractility is the measurement of cardiac pump performance. Cardiac contractility has a direct effect on the cardiac output, the amount of blood the heart pumps in one minute. So if the contractility is compromised, then the heart is pumping a lower amount of blood than optimal.”

According to the site, Hypothyroidism can also lead to heart disease caused by a buildup of mucin. Mucin is a protein substance in the body and can begin to accumulate in an individual with low thyroid function.

Mucin then attaches to water, which can lead swelling in the heart muscle and a weakened heart.
