12 Reasons You Might Be Feeling Cold All the Time

You need more vitamin B12

“People might assume they’re not getting enough iron when it’s really a B12 issue,” says Andrea Moss, a certified holistic nutrition coach in New York, NY. Vitamin B12 anemia can cause coldness, numbness, and low energy, she says. Like iron, most B12-rich foods are animal products, so vegetarians might have a tough time getting enough. Vitamin B12 is found in eggs, yogurt, and cheese. Vegans can sprinkle nutritional yeast—a cheesy-tasting powder—on popcorn or baked potatoes. If you are a vegan, ask your doctor to periodically check your vitamin B12 levels to make sure you’re getting enough. Nutritional yeast isn’t always enough to ensure adequate levels of the vitamin.
