5 foot symptoms that signal serious health problems

Feet feeling cold even in warm weather? That could be a sign of poor blood circulation. When blood doesn’t flow well—like in peripheral artery disease (PAD)—the feet start losing warmth. PAD happens when arteries narrow due to fatty deposits, making it hard for blood to reach the legs and feet. Sometimes, this also connects to heart problems or diabetes. A thyroid issue might also lead to cold feet, especially if it’s underactive (hypothyroidism). When the body slows down, so does blood flow, causing that persistent chill in the toes.
