Always Feeling Cold or Losing More Hair? 5 Signs That May Indicate Iron Deficiency
Do you often feel unusually cold even when the temperature around you seems comfortable? Or have you noticed significantly more hair collecting on your shower drain, pillow or hairbrush? While these changes may seem minor, they can sometimes be linked to an underlying nutritional problem such as iron deficiency.
Iron is an essential mineral that the body needs to produce haemoglobin, a protein in red blood cells that carries oxygen throughout the body. When iron levels become too low, oxygen delivery can be affected and several symptoms may gradually appear.
Here are five signs that may indicate your body is not getting enough iron.
1. Feeling Tired Even After a Full Night’s Sleep
Persistent tiredness is one of the symptoms commonly associated with iron deficiency.
Iron plays an important role in producing haemoglobin and supporting normal energy-related processes in the body. When iron stores become low, you may feel unusually weak, exhausted or mentally sluggish even after getting adequate sleep.
However, fatigue can have many other causes, including poor sleep, stress, thyroid problems and other nutritional deficiencies.
2. Feeling Cold All the Time
If you frequently feel cold while people around you are comfortable, it may be worth paying attention to the pattern.
Iron deficiency can affect oxygen delivery and may contribute to increased sensitivity to cold in some people. This symptom becomes more significant when it occurs along with fatigue, pale skin or reduced stamina.
Feeling cold by itself, however, does not necessarily mean you have an iron deficiency.
3. Getting Breathless During Simple Activities
Do ordinary activities such as climbing stairs, walking quickly or carrying groceries suddenly leave you more breathless than usual?
When iron deficiency progresses to anaemia, reduced haemoglobin can decrease the blood’s ability to transport oxygen. As a result, everyday physical activities may feel more demanding.
New or unexplained breathlessness should not automatically be blamed on low iron, especially when it is severe, sudden or accompanied by chest discomfort, fainting or dizziness.
4. Noticeably Increased Hair Shedding
Finding more hair than usual in your brush or shower drain can be concerning.
Low iron levels have been associated with telogen effluvium, a type of diffuse hair shedding. Interestingly, increased hair loss may become noticeable several weeks or months after the original trigger, rather than immediately.
Hair shedding can also occur because of stress, hormonal changes, illness, thyroid disorders, nutritional problems and certain medications.
5. Pale Skin or Pale Inner Eyelids
Unusual paleness can sometimes occur when haemoglobin levels fall.
Some people may notice that their skin looks paler than usual or that the normally pink inner surface of the lower eyelid appears less pink.
However, looking pale is not enough to diagnose iron deficiency. Blood testing is required to determine whether iron levels or haemoglobin are actually low.
How Can Iron Deficiency Be Confirmed?
Symptoms can provide clues, but iron deficiency cannot be reliably diagnosed from symptoms alone.
A healthcare professional may recommend blood tests such as a complete blood count, ferritin and transferrin saturation to evaluate iron status.
It is also important to find out why iron levels are low. Possible causes include inadequate dietary intake, increased nutritional requirements, heavy menstrual bleeding, blood loss and problems absorbing iron.
Avoid taking high-dose iron supplements without medical guidance. Too much iron can also be harmful.
When Should You Get Checked?
If you are experiencing persistent fatigue, unusual cold sensitivity, increased hair shedding, unexplained breathlessness or pale skin—particularly if several symptoms occur together—it is worth discussing them with a healthcare professional.
The important thing to remember is that these symptoms may point toward iron deficiency, but they do not prove it. Proper blood tests and evaluation are needed to identify the actual cause and determine the appropriate treatment.
