Cold feet are a normal body reaction at low temperatures. 
When the body enters a cold environment, the caliber of the blood vessels of the hands and feet occurs ; therefore, the blood flow is reduced. 
The extremities are the parts of the body most distant from the vital organs, and therefore, reducing the blood supply to the extremities allows the heat and blood flow to the brain and organs to be maintained:

  • From the thorax,
  • From the abdomen.

A temporary exposure to the cold does not cause consequences and the body returns to normal as soon as it heats up.

Generally, those who have cold feet also feel cold in their hands , but it is not always so.

The nerves that regulate circulation in the arms originate on a different level than that of the legs. 
A person can feel cold in their feet even if their hands are warm or vice versa. 
Women suffer more than men, especially at night after a few hours of inactivity.

In Chinese medicine , cold feet and hands are considered to be “yin.” 
A person who is unbalanced to yin (the opposite of yang) has the following characteristics:

1. Weakness , 
2. Paleness, 
3. White tongue , 
4. Need for warmth, 
5. Light urine, 
6. Slow digestion , 
7. Lack of appetite, 
8. Swollen belly .


Causes of cold feet

The problem of hypothyroidism is quite common among women. In this disease the thyroid produces fewer hormones. 
The consequence is a reduced metabolism. 
The metabolism of the body affects:

  • The circulation of blood,
  • The heart beat ,
  • At body temperature.

People with hypothyroidism may be more sensitive to cold and may have other symptoms, for example:

  • Weight gain,
  • Tiredness ,
  • Memory loss ,
  • Dry skin .

The  cryoglobulins  are abnormal blood protein complexes that become insoluble as the temperature begins to fall.

Cryoglobulins are formed when the patient suffers from certain diseases, for example:

This hinders the circulation of blood and can cause cold extremities of the body.

This occurs when, because of the extremely low temperature, the surface of the skin begins to freeze, causing a problem in the blood circulation. 
It usually occurs in the most distant parts of the heart such as the fingers and toes.

‘s syndrome Raynaud ‘s syndrome occurs when small blood vessels in the fingers contract because of low temperature or stress . 
This causes:

  • Discoloration on the fingers and toes,
  • The fragility of the nails.

Since the blood does not circulate freely, the hands and feet become cold.

Peripheral vascular disease (PVD)
This is a medical problem in which blood circulation does not reach the hands and feet causing:

It usually occurs in people who suffer from diabetes , but also non-diabetics can suffer from this problem. 
The symptoms do not improve with heavy socks because the cause is inside the body.

Some infections, such as the flu , can cause:

This is the most common cause of cold feet in children.

Anxiety and stress
the anxiety and stress  can cause:

Other Causes
In addition to these causes, there are a few more reasons:

Smoking damages the blood vessels and causes a barrier in the bloodstream. 
Lack of iron in the blood (especially in women) often affects the production of heat in the body and causes cold in the hands or feet.

Pregnancy can cause vasoconstriction and therefore, the blood flow to the limbs is reduced in favor of vital organs.

The low pressure can cause various symptoms, including cold hands and feet.


Symptoms of cold feet

When the body is exposed to a low temperature, the arteries contract and therefore, in the distant areas (like the feet) the blood flow is reduced. 
These blood circulation problems cause cold feet. 
Symptoms include:

  • Burning sensation , in case of reduced circulation or neuropathy,
  • Pain,
  • Numbness of the feet in case of neuropathy.

People of any age may suffer from these symptoms, but the elderly or the individuals who smoke are more susceptible.


Cold feet in pregnancy

It is not uncommon to have cold feet during pregnancy, especially in the early stages.

One of the causes is anemia . 
According to the National Heart, Lung and Blood Institute (NHLBI) , among the most frequent symptoms of iron deficiency anemia in pregnancy are:

Morning sickness and vomiting can cause:

  • A slight dehydration ,
  • Electrolyte imbalances in the blood.

The consequence may be the feeling of cold in the feet. 
Changes in hormone levels during pregnancy, particularly thyroid hormones , can cause hyperthyroidism or hypothyroidism. 
This can cause the feeling of cold.


Sweaty, cold feet

There are many people who suffer from cold and wet feet. 
It can be very uncomfortable to wear closed shoes to prevent scent from reaching others. 
Often people who sweat a lot suffer from stinking feet. 
In addition, if hygiene is not maintained, there is always a chance of developing infections :

  • On the feet,
  • On the nails.

Causes of Cold and Sweaty Feet
In medical terms, the pathology of sweaty feet is known as ‘plantar hyperhidrosis’. 
It can be caused by various factors, diseases and disorders. 
Here is a list of the most frequent:

  • Genetics – Research shows that if a close family member suffers from excessive sweating , the chances of developing this disease multiply.
  • During the winter it is possible to suffer from this disease if a person always wears closed shoes and stays all day in the office. 
    These conditions do not allow water and excess fluid to escape from the skin pores and sweat glands.
  • The hormonal imbalances in the body can stimulate the sweat glands, causing hypothermia (low temperature). 
    Also menopause in women can cause cold feet because the reduction of estrogens has a negative effect on blood circulation.
  • If a person takes some inappropriate medication , side effects such as wet and cold feet can occur.
  • A person suffering from stress and anxiety can have excessive perspirationthroughout the body, including the feet and hands.
  • There are many young people who sweat a lot when they go to the gym and should take off their socks. This can also occur in consultations with the doctor or physiotherapist.
  • It can occur in smokers and  alcoholics .
  • The disorder can also be caused by certain diseases such as heart attack , heart disease, leukemia and lymphoma .


Always cold hands and feet

disease Circulatory or cardiovascular diseases can cause cold hands and feet. 
When circulation at the extremities of the body decreases, a person may suffer from chronic cold hands and feet. 
The narrowing of the small blood vessels at the extremities can cause the pathology of always cold and purple hands. 
Sometimes cold, purple hands can be a sign of:

  • Lack of oxygen in the blood,
  • Poisoning of blood,
  • Heart problems,
  • Lung problems,
  • Phenomenon of Raynaud.

A cyanosis is always caused by cold and purple feet and hands. This is a disease in which the skin turns blue because of lack of oxygen in the blood. 
Cyanosis is caused by respiratory problems as well as cardiovascular disease.

In newborns it may be a sign of congenital heart disease  (eg lack of tricuspid valve opening). 
In case of sudden development of the blue color, immediate care is necessary.


Nerve damage and neuropathy
A neuropathy can cause cold feet. In this case, the individual has a cold sensation because the nerves that measure the temperature do not work properly.

Carpal tunnel syndrome and tarsal tunnel syndrome
The carpal tunnel syndrome is a condition in which the median nerve is compressed fingers wrists. 
This causes:

At the foot level, the tarsal tunnel can cause pain and tingling in the sole of the footup to the toes; it can also cause cold feet.



Thromboangiitis obliterans
This is a peripheral vascular disorder, also known as Buerger’s disease. 
It occurs in the arteries and veins of small to medium-sized hands and feet. 
Causes an inflammatory reaction that causes an obstruction of normal circulation. 
This disease leaves the hands and feet cold and of purple or blue color.

Heart Failure
It is the inability of the heart to pump enough blood into the body. 
There is accumulation of fluid in the lungs and feet . 
Insufficient blood supply to the extremities causes a persistent feeling of cold in the hands and feet.

The Scleroderma (Hard skin literally) is a chronic autoimmune connective tissue disease. 
It is characterized by:

  • Skin thickened,
  • Fibrosis,
  • Alterations of blood vessels,
  • Inflammation ,
  • Pain.

The scleroderma patient has a persistent cooling sensation.

Raynaud Syndrome
The Raynaud phenomenon is one of the most common diseases that cause cold hands and feet. 
The small arteries of the fingers undergo spasms that cause an obstruction of the blood flow.

When a man smokes and suffers from constant cold hands and feet should stop smoking . 
The cigarette damages the blood vessels, causing an obstruction of the blood flow. 
Smokers suffer from extremely cold hands and feet when the temperature is low, and when they have  atherosclerosis and circulatory problems.

The parasites that live in the intestine are fed with all the nutrients that the individual receives. In this way the person loses weight and can suffer from malnutrition even after eating well. When the body begins to lose vital nutrients, it feels weak and cold.Therefore an individual should control the presence of parasites in the intestine if suffering from chronic cold hands and feet.

Chilies are a lighter form of frostbite, but still very unpleasant. 
Chilblain (also called erythema inferno) is the consequence of extremely low temperature. 
The appliance causes blisters on the fingers and sometimes the ears or tip of the nose when the skin is exposed to extremely cold temperatures. 
Hands and feet may become red or dark blue.


How to warm your feet? The treatment

Keep feet clean and dry. Do not press or rub while cleaning. 
The most important is to protect the hands and feet from exposure to cold. 
In other cases, the treatment is based on the underlying disease.

  • Diabetic patients should monitor blood sugar levels.
  • For anemia, it is necessary to increase the intake of iron and vitamin C. 
    It is possible to do this by eating foods rich in iron and vitamin C.
  • For arteries clogged by atherosclerosis, surgery may be considered.



Natural Remedies for Cold and Painful Feet

  • During the winter, people who are predisposed to chilbler should massage their hands and feet with a hot vegetable oil twice a day. 
    Add a few drops of lemon juice in the oil for more benefits. 
    Scrubbing the area with lemon slices is a quick cure.
  • The eucalyptus, rosemary and mint oils are great for treating chilblains. 
    Use to massage swollen feet ; be careful not to apply the oils on the abrasions. 
    People who suffer from cold feet, while riding a bicycle or mountain bike should apply this ointment before exercising.
  • Boil marigold flowers in the water and wait for them to cool. Add salt. Put hands and feet in this infusion.
  • If the disease is extremely itchy, rub a slice of onion over the area. The onion juice should spread throughout the area. 
    This home remedy reduces itching . The garlic juice is also very effective.
  • A massage with cayenne oil  or the application of cayenne powder is an effective home remedy. It improves blood flow and gives relief. 
    Care must be taken not to apply the oil if you notice even a small crack in the region concerned.
