12 Hidden Signs of Iron Deficiency You Shouldn't Ignore

Brittle Nails and Hair Loss

Iron deficiency can also manifest in physical changes such as brittle nails and hair loss. Nails can become thin, brittle, and prone to breaking, while hair may fall out more than usual. This occurs because iron is vital for the production of keratin, a protein that strengthens hair and nails. Without enough iron, the body prioritizes essential functions over non-essential ones like hair and nail growth. Although these changes might seem purely cosmetic, they can indicate a deeper nutritional deficiency that requires attention and correction.

Cold Hands and Feet

Feeling cold, especially in the extremities, is another symptom of iron deficiency. Iron plays a role in regulating body temperature, and insufficient levels can lead to poor circulation, causing cold hands and feet. This symptom can be particularly noticeable in colder climates or during winter months. While feeling cold can be attributed to various factors, persistent coldness, particularly when accompanied by other signs of iron deficiency, should prompt an evaluation of your iron status. Improving iron levels can enhance circulation and help maintain a more comfortable body temperature.
