What the hell is going on here?

Causes of easy cold hands and feet

1. Cardiovascular dysfunction: This is the most important reason for cold hands and feet. Because blood is pumped by the heart, it brings oxygen to all parts of the body, generates heat energy and warms the whole body, so that hands and feet will be warm. If the heart function is weak and the blood supply is blocked, it will lead to cold hands and feet. Especially for patients with arteriosclerosis, vascular stenosis and obstruction, it affects the normal transmission of blood; Or because of a fever and a cold, it affects the central nervous system of the brain; Or there is something wrong with the sympathetic nerve, so that the muscles can't contract when they are cold, and the heat production is reduced, which will reduce the cold tolerance and make the hands and feet cold.

2. Have low blood pressure or hypoglycemia: Food is an important source of heat energy for the body. If three meals are not on time, you are hungry, or excessive weight loss leads to hypoglycemia, it is easy to get cold hands and feet. Poor blood circulation and insufficient blood supply and oxygen supply in patients with hypotension can also lead to cold hands and feet.

3. Clothes don't keep warm: wearing too thin, or clothes are too hard, too small and too tight, wet and unclean, and the thermal insulation performance is poor, which affects the smooth blood flow and is also a common cause of cold hands and feet.

4. Insufficient nutrition supply: Diet is the main source of energy. If the diet is not balanced, the nutrition supply is not balanced, especially the carbohydrate supply is insufficient, the heat production is reduced, or the food containing iron and iodine is lacking, which can lead to chills and cold hands and feet.

5. Hypothyroidism: Thyroxine is a hormone synthesized and secreted by the thyroid gland with iodine and tyrosine as the main raw materials, which has a thermogenic effect and can accelerate the oxidation process of tissues and cells in the human body and increase calories; Thyroxine can also improve the basal metabolic rate of human body and accelerate the blood circulation of skin, thus generating body temperature and resisting cold. Therefore, if the body lacks iodine for a long time and the raw materials for synthesizing thyroxine are insufficient, the body's ability to keep out the cold will be reduced.
