What should men do if they are afraid of cold?

The weather is cold, which is even more painful for some people with kidney deficiency. Patients with kidney deficiency have different degrees of fear of cold. And people with kidney deficiency often feel cold not only physically when they go to bed every day. They also feel that their quilt is cold from time to time. At this time, it often takes a period of time to adjust before the whole quilt can warm up. It is necessary to further relieve the uncomfortable symptoms. What should men do if they are afraid of cold due to kidney deficiency?

People with this condition are prone to peripheral blood vessel spasms. When exposed to cold air or cold water, the blood vessels in the hands and feet contract, blood circulation is blocked, and the hands and feet are prone to cold and purple. In addition, it may also be due to poor sympathetic nervous function, which leads to the inability to contract muscles to generate heat and resist the cold.

The human body temperature is maintained at 36 to 37.5 degrees Celsius. When the human skin contacts the outside temperature, it is directly transmitted to the life center in the medulla oblongata that controls breathing, heartbeat, body temperature, etc. When it is hot, the body temperature control center will control the sympathetic nerves to be excited, so that the skin pores and sweat pores open to dissipate heat and sweat; when it feels cold, the sympathetic nerves will cause various parts of the limbs, including the muscles near the jaws, to shiver, so that the muscles and fat cells will contract and generate heat energy to resist the cold, which is why people shiver when they feel cold.

Humans are warm-blooded animals, so there is basically no question of "who is more afraid of cold". At the same temperature, some people may be more afraid of cold due to different personal subjective feelings. The fat layer can certainly insulate low temperatures, but because the heat production of fat cells is weaker than that of muscles, people with thick fat are not necessarily less afraid of cold, but may be more afraid of cold!

Some diseases can affect the body's adaptation to cold and heat. For example, patients with hyperthyroidism are intolerant to heat because their sympathetic nerves are overexcited, leading to excessive metabolism. Conversely, patients with hypothyroidism cannot generate enough heat to keep out the cold because of poor sympathetic nerve function.

People who smoke for a long time may have poor circulation in the peripheral capillaries due to insufficient oxygen in the body. When the arterial capillaries are blocked, they may easily feel chills. However, if the venous capillaries are blocked, although they may not feel particularly afraid of the cold, the blood vessels cannot expand during activities, and the blood cannot circulate, resulting in local oxygen deficiency, and the hands and feet may easily become cold.

Urban "lazy people" who usually "would rather lie down than sit, and would rather sit than stand" will also have problems with cold intolerance due to their lower basal metabolic rate.

Women who are afraid of cold should take iron supplements

Generally speaking, women are more afraid of cold than men. Not long ago, two experts from a human health research institute in the United States conducted a group experiment on female volunteers. The experimental report found that people with low tolerance to cold had significantly insufficient iron in their blood. The main reason for women's iron deficiency is menstruation, which leads to a large loss of iron.

As we all know, iron is an important raw material for the production of hemoglobin. Hemoglobin is the main functional substance in red blood cells and is responsible for the transport and metabolism of oxygen in the body. Iodine and tyrosine are the main raw materials for the production of thyroid hormone. Iodine needs to be continuously ingested from food, while tyrosine is generally synthesized in the body. Long-term iodine deficiency will affect the synthesis of thyroid hormone, and the body's ability to resist cold will also be reduced.

How to warm your hands and feet

● Soaking your hands and feet in hot water before going to bed can not only promote circulation in the blood vessels, but also help you sleep.

●After taking a shower or soaking in hot water, put on socks immediately after drying yourself to keep warm.

●If women often have cold feet in winter, they can use a bucket filled with hot water, rice wine and ginger slices (the ratio of hot water to rice wine is 1:1). Use it while watching TV or after get off work in winter to help improve women's fear of cold.

Do some exercise to avoid the cold

Warm reminder: It is recommended that patients with kidney deficiency and fear of cold should exercise moderately when the weather is cold. Once you eat a lot but sit for a long time and do little exercise, it is easier for excess fat to accumulate in the body. So patients with kidney deficiency should do more exercise. This way, blood circulation can be enhanced.
