Feeling cold can be attributed to various factors, including environmental conditions and individual variations in body temperature regulation. However, one potential underlying cause of feeling constantly cold could be a deficiency in certain vitamins. Vitamins play a crucial role in maintaining overall health and well-being, and when there is an insufficiency of specific vitamins, it can affect the body’s ability to function optimally. While there isn’t a specific vitamin deficiency directly linked to feeling cold, deficiencies in certain vitamins can contribute to symptoms that might make individuals more prone to feeling chilly. In this article, we will explore what vitamin deficiency causes you to feel cold?, shedding light on the importance of a well-rounded diet and adequate nutrient intake for maintaining optimal body temperature regulation.

What vitamin deficiency causes you to feel cold?
While there isn’t a specific vitamin deficiency that directly causes a person to feel cold, deficiencies in certain vitamins can contribute to symptoms that might make individuals more prone to feeling chilly. Here are a few vitamins that, when deficient, may impact body temperature regulation:
Vitamin D: Vitamin D deficiency has been associated with various health issues, including reduced circulation and impaired thermoregulation. This can make individuals more sensitive to colder temperatures.
Vitamin B12: Low levels of vitamin B12 can affect the production of red blood cells, which are responsible for carrying oxygen throughout the body. Insufficient oxygen supply can hinder proper metabolism and heat production, potentially leading to feeling colder.
Iron: Although not a vitamin, iron is an essential mineral involved in carrying oxygen in the blood. Iron deficiency anaemia can lead to reduced oxygen-carrying capacity, affecting overall metabolism and body temperature regulation.
Vitamin C: While vitamin C deficiency itself may not directly cause feeling cold, it plays a vital role in collagen synthesis and blood vessel health. Poor collagen production and compromised blood flow can affect body temperature regulation.
How does vitamin D deficiency affect body temperature?
Exact mechanisms are not fully understood, there are several ways in which vitamin D deficiency may impact body temperature:
Vitamin D deficiency has been linked to impaired cardiovascular function, which can lead to reduced blood flow. Proper blood circulation is essential for distributing heat throughout the body, and compromised circulation can make individuals more sensitive to colder temperatures.
Vitamin D plays a role in muscle function and strength. Inadequate levels of vitamin D may contribute to muscle weakness or fatigue, which can affect the body’s ability to generate heat and maintain optimal body temperature.
Vitamin D is involved in modulating the immune system, and deficiency in this vitamin may result in altered immune function. Impaired immune responses can make individuals more susceptible to infections, which can impact body temperature regulation.
Vitamin D deficiency has been linked to disruptions in hormonal balance, including the hormone leptin, which plays a role in regulating appetite and metabolism. Hormonal imbalances can affect metabolism and heat production, potentially leading to feeling colder.
Best Vitamins for maintaining body temperature?
Here are some vitamins that are essential for maintaining optimal body temperature:
- Vitamin B3 (Niacin)
Niacin is involved in energy metabolism and plays a crucial role in maintaining a healthy metabolic rate. Adequate levels of niacin help the body efficiently convert food into energy, which is necessary for maintaining body temperature.
- Vitamin B6 (Pyridoxine)
Vitamin B6 is involved in numerous enzymatic reactions that support metabolism, including the breakdown of carbohydrates and proteins. Proper metabolism is essential for generating heat and maintaining body temperature.
- Vitamin B12
Vitamin B12 is important for the production of red blood cells, which carry oxygen throughout the body. Sufficient oxygen supply is crucial for optimal metabolism and heat production, helping to regulate body temperature.
- Vitamin D
Although primarily known for its role in calcium absorption and bone health, vitamin D also plays a role in maintaining proper muscle function. Adequate vitamin D levels support muscle strength and coordination, which are important for generating body heat and regulating temperature.
- Vitamin E
Vitamin E is an antioxidant that helps protect cells from oxidative stress. It also supports proper blood circulation, which is vital for distributing heat throughout the body.
- Vitamin C
Vitamin C is involved in collagen synthesis and contributes to blood vessel health. Healthy blood vessels facilitate efficient blood flow and temperature regulation.
It’s important to note that a well-rounded diet, including a variety of nutrient-rich foods, is key to obtaining these vitamins. While supplementation may be necessary in certain cases of deficiency, it’s generally recommended to prioritise obtaining nutrients from whole foods. Additionally, individual vitamin needs may vary, and it’s advisable to consult with a healthcare professional for personalised guidance.
Link between iron deficiency and feeling cold?
Here’s how iron deficiency can contribute to feeling colder:
Impaired Oxygen Transport: Iron is a crucial component of haemoglobin, a protein in red blood cells responsible for carrying oxygen to tissues throughout the body. Inadequate iron levels result in reduced haemoglobin production, leading to decreased oxygen-carrying capacity. When tissues receive less oxygen, metabolic processes, including heat production, can be compromised, making individuals more sensitive to cold temperatures.
Reduced Metabolic Rate: Iron plays a vital role in energy metabolism, which influences body heat production. When iron levels are low, the metabolic rate may slow down, affecting the body’s ability to generate sufficient heat. This can lead to a feeling of coldness, especially in extremities like hands and feet.
Impaired Thyroid Function: Iron is involved in the synthesis and conversion of thyroid hormones, which regulate metabolism and body temperature. Iron deficiency can disrupt thyroid function, leading to lower thyroid hormone levels. Reduced thyroid activity can result in a lower basal metabolic rate and contribute to feeling cold.
Altered Blood Flow: Iron deficiency can lead to changes in blood vessel structure and function, affecting blood flow and circulation. Poor blood circulation can hinder the distribution of heat throughout the body, making individuals more susceptible to feeling cold.
Cold Hands and Feet: Iron deficiency can result in a condition called Raynaud’s phenomenon, characterized by reduced blood flow to extremities in response to cold or stress. This can cause hands and feet to feel cold and numb.
Q1: Is feeling cold a symptom of vitamin D deficiency?
Ans: While not a direct symptom, vitamin D deficiency can affect circulation and metabolism, potentially leading to feeling colder.
Q2: Can iron supplements help alleviate feeling cold?
Ans: Iron supplements can help address iron deficiency, potentially improving body temperature regulation and reducing feelings of coldness.
Q3: Is feeling cold a common symptom of vitamin B12 deficiency?
Ans: While not exclusive to vitamin B12 deficiency, feeling cold can be a symptom due to its impact on metabolism and red blood cell production.
Q4: Are women more prone to iron deficiency-related coldness?
Ans: Women are at a higher risk of iron deficiency due to menstruation, and this can make them more susceptible to feeling cold.
Q5: Can iron deficiency-related coldness be reversed with iron-rich foods?
Ans: Consuming iron-rich foods can help address iron deficiency and improve body temperature regulation, potentially reducing feelings of coldness.
