Cold sensation causes: The underlying factors
Feeling constantly cold can be attributed to various underlying health conditions and factors affecting the body's temperature regulation.
Below are specific reasons why you may experience persistent coldness:
1- Iron-deficiency anemia
Iron deficiency leads to a decrease in red blood cells, which are responsible for carrying oxygen to tissues throughout the body.
Without sufficient oxygen delivery, metabolism slows down, resulting in a decreased production of heat and an increased susceptibility to feeling cold.
2- Hypothyroidism
Hypothyroidism occurs when the thyroid gland doesn't produce enough thyroid hormone.
Since thyroid hormones play a crucial role in regulating metabolism, a deficiency can lead to a reduced metabolic rate, impairing the body's ability to generate heat and maintain a stable internal temperature.
3- Low body weight
Individuals with a low body weight often have less insulation in the form of body fat, which serves as a natural barrier against heat loss.
Additionally, a low body weight may indicate a reduced metabolic rate, resulting in less internal heat production and a higher likelihood of feeling cold.
4- Poor circulation
Poor circulation occurs when blood flow is restricted or impaired, preventing adequate distribution of warmth to the body's extremities.
Factors such as narrowed blood vessels, blood clots, or vascular diseases can contribute to poor circulation, leading to cold hands and feet even in normal environmental conditions.
5- Peripheral artery disease
Peripheral artery disease involves the narrowing of arteries in the limbs, typically due to a buildup of plaque.
This restricts blood flow to the extremities, resulting in decreased heat delivery to areas such as the hands and feet, leading to feelings of coldness.
6- Raynaud's phenomenon
Raynaud's syndrome is a condition characterized by exaggerated vasospasms in response to cold temperatures or emotional stress, leading to temporary narrowing of the blood vessels in the fingers and toes.
This reduces blood flow to these areas, causing them to turn white or blue and feel cold and numb.
7- Atherosclerosis
Atherosclerosis is the buildup of plaque in the arteries, which can lead to narrowing and hardening of the blood vessels.
This restricts blood flow and can result in reduced circulation to the extremities, contributing to feelings of coldness in the hands and feet.
8- Diabetes
Diabetes can affect blood circulation and nerve function, particularly in the extremities.
High blood sugar levels can damage blood vessels and nerves, impairing blood flow and sensation in the hands and feet, leading to a sensation of coldness even in warm environments.
9- Blood sugar conditions
Fluctuations in blood sugar levels, such as hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar), can affect blood circulation and perception of temperature.
Low blood sugar levels can trigger shivering and a feeling of coldness, while high blood sugar levels can lead to dehydration, which can also contribute to feeling cold.
10- Dehydration
Dehydration reduces blood volume and can impair circulation, leading to decreased heat distribution throughout the body.
As a result, you may feel colder than usual, especially in your extremities, due to reduced blood flow and heat transfer.
11- Lack of sleep
Sleep deprivation can disrupt the body's natural thermoregulatory mechanisms, leading to fluctuations in body temperature and an increased susceptibility to feeling cold.
Additionally, inadequate sleep can affect metabolism and energy expenditure, further contributing to feelings of coldness.
12- Anorexia Nervosa
Anorexia nervosa is an eating disorder characterized by extreme calorie restriction and low body weight.
Individuals with anorexia often have reduced body fat and muscle mass, which serve as insulation and a source of heat production.
Additionally, malnutrition can impair thyroid function and metabolism, exacerbating feelings of coldness.
13- Vitamin B12 deficiency
Vitamin B12 plays a crucial role in red blood cell production and nerve function.
A deficiency in vitamin B12 can lead to anemia, which reduces oxygen delivery to tissues and impairs heat production.
Additionally, nerve damage caused by vitamin B12 deficiency can disrupt the body's ability to sense temperature accurately.
14- Beta blockers
Beta blockers are a class of medications commonly used to treat conditions such as high blood pressure and heart disease.
These medications work by blocking the effects of adrenaline, which can cause blood vessels to constrict.
However, this can also lead to reduced blood flow to the extremities, resulting in cold hands and feet.
15- Medication complications
Various medications may have side effects that affect blood circulation or metabolism, leading to feelings of coldness.
For example, certain antidepressants, antipsychotics, and antihistamines can interfere with the body's ability to regulate temperature, resulting in increased sensitivity to cold temperatures.
Additionally, chemotherapy drugs and medications used to treat thyroid disorders may also cause cold sensations as a side effect.
Cold sensitivity solutions: Key supplements to consider
Iodine & Selenium
If hypothyroidism is the root cause of your persistent cold sensation, it's likely due to iodine and selenium deficiency.
These minerals are vital for supporting thyroid function and hormone production, with iodine playing a crucial role in hormone synthesis.
Selenium and zinc are also essential for converting inactive thyroid hormones into active ones, helping alleviate cold sensitivity.
- Opt for a natural seaweed supplement for effective iodine supplementation aff).
- Recommended dosages: 200µg/day for selenium and 12 to 15mg/day for zinc bisglycinate.
Iron
Iron deficiency can lead to anemia, resulting in constant coldness.
Iron is also involved in metabolizing fats essential for thermoregulation.
Consider a laboratory blood test to assess ferritin levels before iron supplementation.
Vitamin B12
Deficiency in vitamin B12 can cause anemia, contributing to cold sensitivity.
- Opt for a methylcobalamin supplement to address potential deficiency and improve red blood cell production, alleviating cold sensations, particularly in the extremities (aff).
Vitamin B Complex
Cellular energy generation relies on B vitamins.
Deficiency in these vitamins can lead to decreased energy production and compromised thermoregulation.
Introducing a vitamin B complex can enhance overall energy levels and stabilize body temperature (aff).
Magnesium
Insufficient magnesium levels can result in muscle tension and narrowed arteries, leading to reduced blood circulation and cold extremities.
- Consider a magnesium glycinate supplement to promote blood vessel dilation and restore normal circulation (aff).
Gingko Biloba
If circulatory issues contribute to your cold sensitivity, Gingko Biloba supplement can be beneficial (aff).
Known for its positive effects on blood circulation, Gingko Biloba increases blood flow by dilating blood vessels, particularly in the extremities.
This helps prevent sensitivity to cold in the hands and feet.
Understanding the underlying causes of your cold sensitivity is essential for effective management and supplementation.
The influence of stress on cold sensitivity
In addition to physiological factors, such as thyroid function and blood circulation, stress exerts a significant influence on sensitivity to cold temperatures.
Chronic stress triggers the body's "fight or flight" response, directing blood away from peripheral areas like the hands and feet towards vital organs to prepare for potential threats.
This redistribution of blood flow can lead to reduced circulation in extremities, resulting in a heightened perception of coldness even in moderate temperatures.
Furthermore, prolonged stress disrupts hormonal balance, affecting the body's ability to regulate temperature efficiently.
Thus, addressing stress through relaxation techniques, mindfulness practices, and stress management strategies becomes crucial in alleviating cold sensitivity and fostering overall well-being.
Dietary considerations and hydration: Impact on cold sensitivity
In conjunction with physiological and environmental factors, dietary choices and hydration status significantly influence sensitivity to cold temperatures.
Suboptimal nutrition can disrupt metabolic processes crucial for heat production and circulation, intensifying sensations of coldness.
