The "frozen extremities", that is, the increased sensitivity of the hands and feet to the cold may be due to poor blood circulation, nervous system disorder, diabetes or frostbite. Depending on its exact cause, accompanied by symptoms such as pain, numbness and changes in skin tone.
What few people know is that frozen limbs may also indicate thyroid dysfunction..
Specifically, cold sensation in the hands and feet may be due to slowing of metabolic processes due to hypothyroidism.
The thyroid, the small butterfly-shaped gland located in the neck, is the "control center" of the metabolism of the human body. This means that it regulates how much energy (calories) utilizes the body and therefore how much heat it produces when burning calories. When the thyroid gland is functioning properly, the average body temperature is maintained at the desired levels, that is, about 37 Celsius degrees.
Reduced energy production
But when the thyroid gland works at a reduced rate, as in the case of hypothyroidism, not enough energy is produced to maintain the average body temperature. Alongside, Decreased glandular activity affects the heart's ability to pump blood to different parts of the body. The arms and legs are farther from the heart than any other system in the body, therefore the negative effect on these points is more obvious.
Cold extremities: indication that you need to take an exam
It is advisable to do a self-examination of your thyroid and consult your doctor to recommend the necessary tests if the sensitivity of the limbs to the cold is accompanied by the key symptoms of hypothyroidism., such as persistent fatigue, the unexplained increase in body weight, dryness and itching of the skin, hair and nail sensitivity and persistent constipation.
