12 Reasons You Might Be Feeling Cold All the Time

You have low iron levels

If you’re constantly wondering: ‘Why am I always cold?’, iron-deficiency anemia might be to blame. Red blood cells need iron to carry oxygen into the blood, and low levels of iron could hurt your circulation, says registered dietitian nutritionist Alyssa Tucci, RDN, a registered dietitian in New York, NY. “Coldness in extremities—hands and feet—is most pronounced, because the body is smart, so it diverts blood to vital organs like the heart and brain first,” she says. Meat is the most common dietary source of iron. Leafy greens and legumes are good sources, but pair them with a vitamin C-rich food like red pepper for maximum absorption, she says; it’s harder to absorb iron from plants.
