Why do my feet get cold?

Most causes of cold feet are not serious. The reason in many cases is simple: there is not a sufficient supply of warm blood flowing through the fingers and toes. However, behind there may be reasons and motives such as:

Poor Circulation - Good blood circulation is key to regulating body temperature. When the blood does not circulate well throughout the body, the extremities have the worst time and the coldest. Poor circulation can be caused by conditions like anemia or lifestyle habits like not getting enough exercise. A simple and effective way to improve circulation is to exercise and stay well hydrated.
Raynaud's disease: This condition makes certain parts of our body feel numb and cold in response to cold temperatures and stressful situations. What happens is that the artery responsible for the blood supply narrows, limiting the supply to areas such as the fingers and toes. Skin needs blood to feel warm and alive. If this does not work well, color changes can be seen in the fingers; it is a direct sign of what is happening under the skin. It can also affect the peripheral points of the body such as the ears or nose.
Peripheral neuropathy: When we experience the sensation of cold feet even though they are not cold to the touch, it may be due to peripheral neuropathy, which occurs as a result of nerve damage caused by an injury or an underlying medical disorder. Peripheral neuropathy often begins in the longest nerves in the body, running down to the toes. Symptoms, therefore, appear first on the feet and then on the lower legs. Some symptoms are numbness, tingling, or itching.
Diabetes: Diabetes is one of the most common causes of peripheral neuropathy.

Vitamin deficiency: it can also lead to peripheral neuropathy and therefore cold feet.

Liver or kidney disease, metabolic problems, infections, or exposure to toxins can also be reflected in a constant cold in the feet.

Excessive sweating: Hyperhidrosis can also make your feet feel cold, especially when evaporation quickly cools them down. This can often be caused by nervous moments.

Smoking: although we usually associate smoking with heart disease and cancer risk, it can also be a major cause of cold feet. The simple act of smoking a cigarette can significantly lower the temperature of your feet. And this happens because nicotine is a vasoconstrictor that causes blood vessels to contract, thus decreasing the amount of blood that can flow through them. The areas where the effect is most noticeable are the hands and feet. Inhaling a single cigarette can reduce blood flow to your feet by 50%, and it may take up to an hour for this flow to return to normal.
Anemia: something as common as iron deficiency can also affect the regulation of body temperature.

One of the main ailments that can affect the feet concerning cold are frostbite and chilblains, a dermal injury caused by prolonged vasoconstriction and that ends in hypoxemia and inflammation of the vascular walls. They also tend to appear, associated with low temperatures, problems such as dermatitis, and eczema.

Tips to prevent cold feet
Move regularly - Something as simple as getting up and moving can be one of the best ways to warm up the body and help blood flow to and from the feet. Moving allows us to reactivate circulation and warm up. Also massaging the feet can help improve circulation and maintain a proper temperature.
Wear suitable socks and shoes: warm socks and natural fibers such as cotton can help us to have warmer feet. Footwear is also essential and the best ally for the coldest months of the year. It is preferable to have a rubber sole (a non-conductive material and therefore a good insulator).
Follow a healthy diet: foods rich in magnesium, calcium, and vitamins E, K and C help us improve vascular tone and, consequently, circulation. Some hot spices like pepper helps to increase the heart rate. Dairy products, on the other hand, can increase the feeling of cold, and caffeine compresses the blood vessels.
Avoid alcohol: There is a false belief that alcohol helps you warm up. But be careful with this idea, because what it does is contribute to dehydration of the epidermis that increases the risk of suffering from chilblains.
Take warm and cold water baths: this is especially recommended for those with circulation problems or after practicing winter sports such as skiing. Do not try to warm your feet in a direct source of heat because it increases the risk of chilblains.
