Gender and weight

Women often feel colder than men because the amount of estrogen hormone is higher than that of men.Moreover, women often have less muscles in the body, so they are less cold.Women in menopause or pregnancy, hormonal imbalance can occur inside the body.At this time, estrogen levels increased, leading to many abnormal symptoms such as sweating, pain, difficulty sleeping, often feeling cold ... Therefore, the change in the level of hormone estrogen is the main culpritCausing this cold feeling.

Low body weight makes you feel cold due to two causes.Firstly, when you are too thin, you will lack the amount of fat needed in the body to protect you from cold temperatures.Secondly, due to the low body mass index, you do not need to eat or eat very little as the amount of calories provided for the body is not enough, leading to reducing metabolism and the result is not enough heat to warmBody.

Lack of sleep

Lack of sleep can cause damage to the nervous system, reduce activity in the hypothalamus, the brain area controls the body temperature that makes you always feel cold.The fatigue after a night of insomnia causes the exchange process to take place at a slow speed, thereby making the heat production less and blood circulation slower, making the body feel colder.

The body lacks water

Water accounts for 60-70% of the human body weight and helps to regulate the body temperature.The body has enough water will always be warm because water contributes to the metabolism.Lack of water makes the metabolism slow, so the production of heat is less, the body will always feel cold.The recommended amount of water is about 2 liters per day.If you exercise, pay more attention than before and after exercise.

Poor circulation

If your hands and feet always feel like ice but the rest of the body feel normal, it may be due to blood circulation disorders or cardiovascular problems.Cold limbs are a sign that the heart does not pump blood effectively or blocked arteries to prevent blood from flowing into the fingers and toes.

Smoking can also be a cause of poor circulation because it clog blood vessels.Another ability to think about is Raynaud's syndrome.This syndrome is the result of the disruption of blood supply in some body parts due to the spasm of the artery smooth muscles, causing the blood vessels in the hands and feet to temporarily narrow, making you always feelcold.

Diabetes and blood pressure problems

Unsectal diabetes can be a cause of peripheral neuropathy that causes chills in the hands and feet.

People with blood pressure (high blood pressure and low blood pressure) often feel that their hands and feet are always cold.A person with low blood pressure, leading to anemia and oxygen to the skin, the body temperature is reduced.For people with high blood pressure, blood circulation often faces many difficulties, so the amount of blood to the limbs is not much.Therefore, in both cases, the patient feels colder than usual.

Thyroid disorder

Many health problems are caused by the thyroid.Always feel cold is a warning sign of hypothyroidism, that is, the thyroid does not secrete enough hormones needed to maintain good function, so the metabolism is slow, preventing the body producing heat.

Diets not scientific

Anorexia is a diet disorder that makes the body thin and one of its symptoms is often cold.The diet is unhealthy, snacks instead of the main meals with nutritious foods and the necessary vitamins will make the body weak, often tired and reduce cold resistance.Snacks often have little nutritional value, so it affects the body's normal weight and temperature.When your body temperature is not stable, it is more difficult for you to adapt to the weather.

The body lacks substance

Iron deficiency:Is one of the chronic reasons.Iron is an important mineral to help red blood cells transport oxygen to all organs in the body, bring heat and other nutrients into all cells.If there is not enough iron, red blood cells cannot effectively perform this task, making you feel cold.Iron deficiency can also lead to hypothyroidism, which will make the body feel colder.

Lack of vitamin B12:The body deficient in vitamin B12 can cause anemia that makes you have low body temperature so always feel cold.
