You’re a woman
There’s anecdotal evidence that women often feel colder than men (see who’s voted most likely to steal the covers or raise the office thermostat) but not a ton of scientific evidence. That said, a 1998 study did find that women’s core temperatures tend to be about 0.4 degrees Fahrenheit warmer than men’s, their hands are almost 3 degrees colder on average, a University of Utah study found. “It’s not a huge difference, but it might be why women have the sensation of feeling colder,” Dr. Rohr says. Now, find out how to feel warmer in cold weather.
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. Don’t ignore these other signs of iron deficiency, either.
