Why are some people always cold?

We all know someone who is always cold, even when it’s the hot season. We gently tease the person, saying that he or she is exaggerating, or maybe is overreacting, thinking the person is skittish and that’s all.


Nevertheless, we often underestimate the continuous chilliness. Not enough people make the effort to see the GP to know what’s wrong with them. However, if it’s your case, you shouldn’t hesitate go to the GP, in order to understand where this unpleasant sensation comes from. As a matter of fact, being cold all the time is maybe due to lots of reasons, too often unknown to the public…


You may have guessed it, we are going to talk about the various causes of this permanent sensation of cold and how to fight them. Unfortunately, the continuous sensation of cold can hide a health issue. But do not worry, there are plenty of solutions to fight against it. The aim of this article is not to scare you or to encourage you to go to the doc as soon as you are a bit cold. We simply try to alert you against some of these causes.


Let’s get started!

The most common causes explaining the sensation of cold

Among these causes, the most common one is the iron deficiency. Affecting more women than men, this deficiency manifests itself in a decrease in body heat, a continuous sensation of cold, pale skin and a permanent tiredness at the least effort. Indeed, when we’re lacking iron, our body finds it much harder to warm up and tries to regulate its temperature by burning off more energy, hence the tiredness.


There is a technique to fight against this kind of symptom that never fails: you have to eat food that contains a lot of iron. Try meat, pudding, lentils, beans, liver, fish… Another factor is tiredness, which we accumulate and tend to put aside. The excessive lack of sleep disrupts the nervous system, and has a strong impact on a lot of the brain mechanisms (the hypothalamus), in charge of the regulation of our internal temperature. As a result, the body produces less energy and a constant chilliness settles down.


In order to fight against tiredness, there is nothing simpler than sleeping between 7 and 9 hours per day. Watch less TV series and go to bed earlier, your body will thank you. The last factor which is often responsible for a permanent sensation of cold is dehydration. Hydration is really important, especially to fight against temperature changes in winter. When you don’t drink enough, your body tries to withhold the water that remains. This action requires a decrease of the body heat, in order to stay into a “comfort zone” which provoke the sudden chilliness. In order to avoid dehydration, you have to drink approximatively 1, 5 litres a day.


I’ve listed you some factors which could lead to a permanent sensation of cold, but there are others, much more pernicious.

Raynaud’s disease: a plausible explanation to this sensation of coldness

Raynaud’s disease is a chronic pathology, which affects approximatively 3 to 5% of the population. 3 out of 4 people affected are women from the age of 15 to 40 years. This disease is characterized by a blood flow disorder in the extremities of the body, such as the fingers or the toes. When it’s cold, the blood vessels contract in order to confine the heat loss (this is what we call vasoconstriction). For those who suffer from Raynaud’s disease, the vasoconstriction becomes excessive, the blood cannot flow to the extremities. The affected areas become white, numb, cold and insensitive, which can be really painful.


This disease can also affect the nose, the lips or the earlobes. A crisis can last several minutes to several hours! Be careful to not make the confusion between Raynaud’s disease and Raynaud’s symptom: the first one is the primary form of the pathology (90% of the cases). The symptoms are mild and don’t lead to tissue or vessel damages. The disease appears between the age of 15 and 25 and can disappear after several years of treatment.


Raynaud’s syndrome is much more pernicious: it is a secondary form of the pathology and is generally caused by diseases touching blood vessels, such as scleroderma. I won’t go into too much details regarding Raynaud’s symptom; let’s focus on Raynaud’s disease.


The disease is diagnosed with a clinical examination or with blood tests. It generally triggers when in contact with cold environment or with a significant rush of stress. A crisis begins with a change in the skin colour, a global cooling, a numbness of the affected areas, some tingling and finally slight swellings. In order to stop a crisis, you just have to get in contact with something hot for a few seconds, and you’re good to go.


However, some symptoms can take the form of aches in the extremities of the body, crisis of pallor or a hardening of the skin. Don’t worry, treatments exist. Most of the time, doctors will advise you to wrap you up well, even indoor and to use isolators when you touch something cold or to take something out of the fridge. Other factors can also trigger the disease such as smoking, headaches, some nervous system troubles, frostbites, and the continuous exposure to the vibrations of some heavy electronical tools.


At this stage of the article, I’m sure you have become hypochondriac. You’ve already scheduled an appointment with a GP and you’ve probably bought a tonne of medicines. There is a solution to all of this: I’m going to show you a revolutionary product that will help you bear this symptoms!
