Are you cold all the time? There are several medical reasons

December 15, 2022

Experts share what could be behind your constant chills.

We share with you some medical reasons why you are always cold.

You have low iron levels

Iron deficiency anemia could be to blame. Red blood cells need iron to carry oxygen to the blood, and low iron levels could harm circulation, says registered dietitian nutritionist Alyssa Tucci, of New York, NY.

“Coldness in the extremities (hands and feet) is more pronounced because the body is smart, so it first shunts blood to vital organs like the heart and brain,” she says.

You need more vitamin B12

Vitamin B12 anemia can cause coldness, numbness, and lack of energy, she says. Like iron, most foods rich in vitamin B12 are animal products.

Vitamin B12 is found in eggs, yogurt and cheese.

Low body weight

Being underweight could mean you're always cold for two reasons. Fat works as an insulator, so having less fat may mean you can't retain heat well.

Plus, cutting calories can slow your metabolism, giving your body less energy to heat itself.

If you're trying to gain weight, it's recommended to stock up on high-calorie foods with good fats, such as nut butter, full-fat Greek yogurt, and dried fruit.

Dehydration

When your body doesn't have enough water, it can't circulate blood as effectively. Water also retains heat, meaning dehydration could leave your body without the temperature retention benefits of H2O .

It is recommended that, to stay hydrated, you try to drink half your weight in ounces of water. For example, if you weigh 150 pounds, try drinking 35 ounces throughout the day.
