I’m the type of person who is ALWAYS cold. Even when other people feel comfortable in pants and a t-shirt, I have to be bundled in a long sleeve shirt, hoodie, and blanket. I decided to do a bit of research on the topic, and here is a brief list of some of the most common and prevalent causes of always being cold.
Note: I have excluded common health disorders and illnesses, as I am not (yet) a healthcare professional, and I am not seeking to diagnose anyone.
1. Sleep deprivation
Chronic fatigue is known to slow down your metabolism, making you feel cooler than usual during the day. It can be hard, but try to get at least a good 7-8 hours of sleep per night!
2. Low iron
Iron helps your erythrocytes (red blood cells) carry oxygen throughout your body, bringing nutrients and heat to body cells. Eat some red meat, eggs, or take an iron supplement.
3. Not enough Vitamin B12
Low bodily vitamin B12 can cause coldness, numbness, and low energy. Getting more Vitamin B12 can be as simple as eating an egg, some yogurt or cheese- all good sources of B12. Of course, you can also always get B12 supplements (they come in gummy form too)!
4. Dehydration
Staying hydrated can improve many common, benign health issues, including feeling cold all of the time! If you are hydrated, the water will trap heat, releasing it slowly, allowing your body temperature to stay in an optimal range.
