What Are the Causes of Body Coldness?
Experiencing cold sensations occasionally, especially in cold weather, is quite normal. However, some individuals may feel cold most of the time. This condition may be attributed to various physiological processes occurring within the body. For instance, women tend to have a lower metabolic rate compared to men, which results in their bodies generating less energy naturally.
In certain circumstances, persistent coldness may indicate an underlying health condition. Below are some potential causes:
Iron Deficiency Anemia
Being diagnosed with anemia means having a reduced level of red blood cells, leading to insufficient oxygen in the body. This can induce feelings of coldness, fatigue, and additional symptoms, such as:
- Pale skin, fingernails, lower eyelids, and gums.
- Shortness of breath.
- Restless leg syndrome.
- Dizziness or weakness.
If you suspect you might have anemia, it is advisable to consult a healthcare professional regarding iron supplements and the appropriate dosage based on your condition.
Hypothyroidism
The thyroid gland plays a pivotal role in regulating metabolic processes, which are the chemical reactions that provide energy to the body. If the thyroid fails to produce adequate amounts of thyroid hormone, or if the body is unable to properly process this hormone, hypothyroidism may result.
Hypothyroidism can lead to feelings of coldness, along with the following symptoms:
- Dry skin.
- Thinning hair.
- Fatigue.
- Irregular menstrual cycles.
- Constipation.
- Weight gain.
Poor Circulation
Poor circulation refers to decreased blood flow to the extremities (hands and feet), often linked to other health conditions such as diabetes and cardiovascular diseases. Additional potential symptoms may include:
- Tingling and numbness in the hands and feet.
- Pain in the extremities.
- Muscle cramps.
Raynaud’s Phenomenon
Raynaud’s phenomenon is a condition affecting blood vessels, primarily narrowing the arteries in the fingers and toes, resulting in reduced blood flow and sensations of coldness in individuals affected by this condition.
Anorexia Nervosa
Individuals with anorexia nervosa exhibit significant weight loss and an intense fear of gaining weight. This disorder often leads to a lower core body temperature, reduced fat levels, and a decreased metabolic rate—all contributing factors that can result in a person feeling excessively cold.
Diabetes
Uncontrolled diabetes can also be a contributing factor to sensations of coldness. When sugar levels are not well-managed, they can gradually damage the nerves in the hands and feet, which are responsible for conveying signals to the brain regarding temperature. Consequently, nerve damage may lead to cold feelings in the extremities.
Other Causes
Several additional factors may contribute to sensations of coldness in the body:
- Inadequate sleep.
- Certain medications, such as:
- Beta-blockers, typically used for heart conditions.
- Cancer treatment drugs.
- Hormonal contraceptives.
- Hormone replacement therapy.
- Immunosuppressants.
- Statins used to lower cholesterol levels.
- Hormonal changes during the perimenopausal phase.
- Pneumonia.
- Fibromyalgia, also known as chronic widespread pain.
When to Consult a Doctor?
You should contact your healthcare provider or seek medical advice if you experience any of the following symptoms in conjunction with cold sensations:
- Tingling in your hands or feet.
- Severe fatigue.
- Unexplained weight loss.
- Pulsating pain in your extremities.
