The reasons for the constant feeling of cold are numerous, but some can be a serious warning. From hormonal disorders to anemia, but also to more serious medical conditions, experts reveal the background of that uncomfortable feeling.
If you are cold because the temperature dropped by about 10 degrees Celsius in just one day – this is perfectly normal, but if you shake while everyone around you is comfortable – it may be an indication of health problems. Make sure one of these causes is not to blame for the constant freezing.
You are too weak
Light weight, especially when your BMI (body mass index) is 18.5 or lower, can automatically mean that you are colder. When you are thin, you lack the proper level of body fat that would “isolate” you from the low temperature. Also, to maintain such a low BMI means that you have either drastically reduced your food intake or eat almost nothing. And when you skip calories, you slow down your metabolism, which means it doesn’t produce enough body heat.
Cold intolerance can be added to the long list of health problems for which we can thank that butterfly-like gland in the neck.
– If you are always cold, it may mean that you suffer from hypothyroidism, which means that the thyroid gland does not secrete enough hormones – explains Dr. Phillips. Even without proper levels of this hormone, it slows down your metabolism and prevents your body’s “engine” from producing enough heat. Other signs of this problem are: thinning hair, dry skin and weakness.
Low iron levels are a common cause of chronic colds. Iron is a key mineral that helps red blood cells carry oxygen throughout the body, which also means carrying heat and nutrients to every cell. Without enough iron, red blood cells can not do their job effectively, and you are cold and shivering.
If your feet and hands are always icy and the rest of your body is at a comfortable temperature, you have problems with circulation, which means that due to a certain problem, the blood does not reach the extremities. Cardiovascular disease may be the cause of this, as this indicates that the heart is not pumping your blood efficiently or that a blockage in the arteries is preventing blood from reaching your fingers. Otherwise, smoking has a very bad effect on the circulation.
Lack of sleep
Lack of sleep can “destroy” your nervous system and cancel out brain functions that affect body temperature. It is not entirely clear why this happened, although research suggests that insufficient sleep reduces activity in the hypothalamus, the part of the brain responsible for regulating body temperature.
An early sign of diabetes
Uncontrolled diabetes can cause a condition called peripheral nephropathy, which affects the nerves that are responsible for feeling the touch of the hands and feet.
Stiffness and sometimes pain in the arms and legs are felt, and because these nerves are also responsible for sending a message to your brain about the feeling of fever, your arms and legs may also be cold.
Diabetic nephropathy develops gradually, so you may not be aware of its existence. But if you have diabetes or have symptoms of the disease, the first three are usually frequent urination, feeling tired and increased thirst, see a doctor.
Lack of vitamins
Winter hardiness can be caused by a lack of vitamin B12, which can be found in foods of animal origin, and plays a major role in reducing the feeling of cold. The body needs vitamin B12 to produce red blood cells that distribute oxygen throughout the body. Deficiency of this vitamin causes anemia, decreased red blood cell count and finally cold, reports Kliks.ba.
