Feeling colder than usual, more tired or generally run down is often blamed on the weather, but for some people these changes can be linked to low iron levels. In this article, we explain why your symptoms can worsen in the colder months, and when it may be time to take action. [![Download Our Product Brochure](https://hubspot-no-cache-eu1-prod.s3.amazonaws.com/cta/default/143521365/interactive-230353293551.png)](https://www.suresign.com/hs/cta/wi/redirect?encryptedPayload=AVxigLISjKmuF0FBkzwkOx6E4HSdM1JVHafX1wPZ2%2F0%2BAE4%2F6UsOPfzWyfXod2p1p3ikzzAlfBUuGqapjhv6hzTM4xib5jdlwKYB3nj02U%2BdpPoo6xCFiulMGiEU0a4zoiwPXZ5cadKVLSzTiKeWolJN4x7RCAbl0yaF7alEtQA7OETsQwvJIAnLKL732EeSag%3D%3D&webInteractiveContentId=230353293551&portalId=143521365) ## What does iron do in the body? Iron plays a key role in making haemoglobin, the protein in red blood cells that carries oxygen around the body. When your iron levels are low, tissues and organs receive less oxygen, which can lead to fatigue, weakness and sensitivity to cold. During winter, when the body is already working harder to regulate temperature and energy levels, the effects of low iron can feel more noticeable. ## Why symptoms can feel stronger in winter: - Feeling colder than at other times: One of the lesser-known effects of iron deficiency is difficulty maintaining body temperature. Reduced oxygen delivery can affect circulation, making hands and feet feel cold, particularly in colder weather. - Increased fatigue: Shorter days, less sunlight and disrupted routines can all contribute to tiredness. When iron levels are already low, this seasonal fatigue can feel heavier and harder to shake. - Reduced immunity: Iron is involved in immune function. In winter, when coughs and colds are more common, low iron may make it harder for the body to recover quickly, adding to the feeling of being unwell. ## What are signs of low iron deficiency? Symptoms can vary, but common warning signs include persistent tiredness, shortness of breath, pale skin, headaches and dizziness. Some people also experience cold intolerance, brittle nails or restless legs. Because these symptoms overlap with general winter sluggishness, iron deficiency can easily be overlooked. NHS[low iron symptoms](https://www.suresign.com/ciga-healthcare-blog/monitoring-your-iron-levels-in-autumn): According to NHS guidance, symptoms of iron deficiency anaemia may include fatigue, lack of energy, breathlessness, noticeable heart palpitations and difficulty concentrating. In colder months, these symptoms may become more obvious or be mistaken for seasonal illness, delaying investigation and treatment. ## When to consider testing? If symptoms persist or worsen during winter, testing your iron levels can provide clarity. For people looking to check their vitamin and mineral status at home, choosing the best vitamin deficiency test kit available to you is important. Reliable tests can help identify whether iron deficiency may be contributing to how you feel, allowing you to seek appropriate advice. Testing is particularly relevant if you have known risk factors, such as heavy periods, dietary restrictions, pregnancy or a history of low iron. ## Managing iron deficiency through winter If an iron deficiency is confirmed, treatment may involve dietary changes, supplementation or medical follow-up, depending on severity. Eating iron-rich foods, pairing iron with vitamin C and following professional advice can all support recovery. Addressing deficiency early may help reduce the impact of [winter-related fatigue](https://www.suresign.com/ciga-healthcare-blog/vitamin-d-self-tests-in-pharmacy) and cold sensitivity. ## Next steps Managing an [iron deficiency](https://www.suresign.com/iron-deficiency) can feel more challenging during the winter, when the body is under additional strain. However, recognising the signs and considering home testing may help you reduce the impact of winter-related symptoms.
