When the weather gets cold, people will feel cold, which is a normal physical reflection. But some people seem to be particularly sensitive to "cold", even if it has nothing to do with climate change, they will feel cold. What is the reason? In fact, fear of cold may be related to other reasons.

The feeling of cold. More common in menopausal women. The main reason is the decrease of estrogen level in the body, which leads to the instability of neurovascular function. Due to poor blood circulation, patients will have chills in the waist, back, abdomen, hands, feet or whole body. At this time, patients need to carry out cold-resistant exercise and diet adjustment. For example, go to outdoor activities, such as walking, dancing, playing badminton and so on. Consciously eat more warm and cold food.

Iron deficiency If people often feel cold, it may be caused by insufficient iron in the body. Because iron participates in the synthesis of heme containing iron in human body, it can improve the oxygen carrying capacity of blood, so the oxygen supply in peripheral tissues of people with iron deficiency will be reduced, and hypoxia will lead to obstacles in energy metabolism of tissues, and natural people will feel cold due to insufficient heat production. Therefore, we should pay attention to supplement iron-rich foods, such as lean meat, fish, animal liver, celery, mushrooms, black fungus and so on.

Insufficient secretion of thyroxine. Thyroxine is an endocrine hormone, which participates in the body's material metabolism and can accelerate the burning of sugar, protein and fat to release energy. At the same time, it can also accelerate the heartbeat, raise blood pressure, accelerate the blood circulation of peripheral organs such as skin, and increase heat. Therefore, insufficient secretion of thyroid hormone will reduce heat production, so I am afraid of cold. Iodine is involved in the synthesis of thyroxine in the body. Eating more iodine-rich foods such as kelp, fish and shrimp can improve the ability to keep out the cold.

Hypotension. It is easy to cause poor peripheral blood circulation, insufficient blood supply to patients' hands and feet, and tissues can't get oxygen and energy substances needed for energy metabolism, which is easy to make people often feel cold. This requires people to strengthen exercise and diet regulation at ordinary times. In addition, low blood pressure can easily cause dizziness, shock and other symptoms. People usually move slowly, don't stand up suddenly, and don't stand in one place for too long. After waking up, lie down for a while and sit up slowly.
