We all experience the feeling of cold now and then, but if you’re cold for a long time it’s worth finding out what’s behind it. This symptom is not only unpleasant, but it can also be a warning that your body is having trouble maintaining a normal temperature.
- A constant feeling of cold may signal a problem with maintaining body temperature.
- Common causes of cold are thyroid disorders, anemia, aging, and malnutrition.
- Persistent cold with fatigue or weight change requires a medical examination.
Body temperature regulation depends on a number of factors including metabolism, blood flow and hormone levels. If any of these systems are out of balance, you may start feeling cold all the time. Although this condition is not a disease in itself, it can indicate a more serious problem. Common causes of feeling cold include thyroid problems, anemia, aging, poor circulation, and low body fat.
The human body maintains its internal temperature through a complex process involving the brain, blood vessels, muscles and hormones. When you’re cold, your blood vessels constrict to keep warm and your muscles start to shiver. If any part of this system is disrupted, your body may have trouble keeping warm. This can lead to a constant feeling of cold even in a normal or warm environment.

Lifestyle factors such as diet and hydration can affect heat generation. A diet low in important nutrients, especially iron and vitamin B12, can worsen the feeling of being cold. The reason is that these substances are necessary for healthy blood circulation and sufficient energy. Sufficient hydration is also important, which maintains blood volume and improves temperature regulation. Therefore, the adjustment of eating and living habits is crucial in the fight against persistent cold.
Common medical causes of feeling cold all the time include:
Hypothyroidism – if the thyroid gland is less active, the metabolism slows down. This can reduce heat production and lead to frequent cold sensations. Other symptoms of hypothyroidism include fatigue, weight gain, dry skin, and depression.
Anemia – this condition occurs when you have fewer red blood cells or less hemoglobin than normal. As red blood cells carry oxygen around the body, the disease can cause a poor supply of oxygen to the tissues, leading to feeling cold, tired and weak. The most common cause of anemia is iron deficiency, but it can also occur due to vitamin deficiency or chronic diseases.

Poor circulation and vascular problems – when blood flow to the extremities is reduced, the hands and feet may feel cold or numb. Conditions such as peripheral arterial disease, Raynaud’s phenomenon or even prolonged sitting can aggravate this problem. Improving circulation by moving or avoiding smoking can help reduce the feeling of cold. Warm clothes and heated blankets will bring immediate relief.
Low percentage of body fat – body fat acts as insulation and helps maintain heat. If you therefore lack it, whether due to genetic reasons, an inappropriate diet or illness, you may feel more cold.
Other possible causes of a constant feeling of cold include chronic diseases (diabetes, kidney disease or autoimmune disorders), taking certain medications, living in a colder environment or stress and anxiety.
When should you see a doctor?
A persistent feeling of cold accompanied by other symptoms such as fatigue, weight changes or numbness should be a reason to visit a doctor. Early diagnosis of diseases can help prevent unpleasant complications. Use these tips to stay warm and comfortable:
- Dress in multiple layers to keep warm.
- Keep warm at home and use blankets.
- Be active to promote circulation and heat generation.
- Eat regularly and in a balanced way to boost your metabolism.
- Limit caffeine and nicotine, which can constrict blood vessels.
