Feeling a chill every now and then is normal, but if you constantly feel cold even when bundled up or inside a heated space, there might be an underlying medical reason. If you’re always cold while others feel comfortable, it’s essential to consult your doctor. “Healthy bodies can regulate temperature in cold environments for about an hour,” explains Kaley Wilson, a family medicine nurse practitioner at Marshfield Clinic Health System. “If your body doesn’t try to maintain core body temperature after spending time in the cold, or you consistently feel cold when others are warm, then it’s time to talk to your doctor.”
Six Medical Reasons You Might Always Be Cold
Several medical conditions can contribute to feeling cold persistently. Here are six common culprits:
1. Hypothyroidism
“This is one of the most common reasons people always feel cold,” says Wilson. Hypothyroidism, or an underactive thyroid, slows down metabolism, hindering the body’s ability to generate sufficient heat to maintain core body temperature.
2. Anemia
Anemia, characterized by a deficiency of healthy red blood cells or hemoglobin, impacts the body’s ability to carry oxygen, heat, and nutrients. Low hemoglobin levels directly affect heat transfer throughout the body.
3. Poor Circulation
Underlying arterial disease can restrict blood flow, making it difficult to maintain core body temperature, especially in the extremities. Smoking also constricts blood vessels, similarly affecting temperature regulation.
4. Raynaud’s Phenomenon
Raynaud’s phenomenon causes blood vessels, particularly in the hands and feet, to constrict excessively in response to cold temperatures. This leads to a noticeable coldness and often numbness or tingling in the extremities.
5. Diabetes
Poorly managed diabetes can lead to nerve damage (neuropathy), which impairs the body’s temperature regulation mechanisms. This can result in a persistent feeling of coldness.
6. Dehydration
Adequate hydration is crucial for metabolism, the process of breaking down food for energy and heat production. Dehydration slows metabolism, preventing the body from generating enough energy to stay warm.
Tips for Getting Warm and Staying Safe
While seeing a doctor is crucial to address the underlying cause of chronic coldness, there are steps you can take to stay warm:
- Dress in Layers: Opt for layers of clothing, with inner layers made of wool or polypropylene for optimal heat retention. Don’t forget a hat and gloves!
- Stay Hydrated: Drink warm beverages like tea or hot chocolate to help boost your internal temperature.
If you frequently feel cold and don’t know the cause, be cautious in cold weather. Your body may be more susceptible to cold-related injuries. “People who know they have medical conditions that make them feel cold can take precautions to be safe while enjoying winter activities,” advises Wilson.
Seek Medical Advice
If you’re concerned about constantly feeling cold, consult a healthcare professional. They can perform necessary tests to diagnose any underlying medical conditions and recommend appropriate treatment options.
