Our feet do far more than support us—they can reveal early warning signs of heart problems. Because the heart pumps blood to every part of the body, circulation issues often appear first in the feet. Persistent coldness in the toes may indicate poor circulation from weakened heart function.

Swelling in the feet or ankles, especially after long days, can signal fluid buildup linked to heart failure. Discoloration—bluish or pale tones—suggests low oxygen or restricted blood flow. Tingling, numbness, or pain when walking could point to peripheral artery disease. Sores that heal slowly are another danger sign of poor circulation. If you notice these symptoms, seek a cardiovascular evaluation promptly—your feet may be warning you to protect your heart.
