Improve cold hands and feet
Recently, on the # after winter legs and feet do not cover the heat to find out the lower extremity vascular blockage # this topic on the hot search, the doctor said, cold hands and feet in winter, to small cardiovascular “blocked”.
According to relevant statistics, more than 60% of people in China regularly have cold hands and feet, and even have difficulty sleeping due to the cold, especially women.
So why do you get cold hands and feet?
Cold hands and feet are a symptom of poor blood circulation
Cold hands and feet, a common symptom caused by poor blood circulation in the extremities, have a strong relationship with the cardiovascular system.
Blood carries the necessary oxygen, nutrients and metabolites from the heart and is transported through the bloodstream to the cells to produce energy to generate heat in the body and maintain normal body temperature.
Our hands and feet are farther away from the heart, the blood supply is poor, coupled with the poor insulation ability of the thin fat layer on the surface of hands and feet, in the cold environment, when the temperature of the skin is lower than the ambient temperature, the blood vessels of the skin will contract, blood flow will be reduced, and the blood circulatory system will retreat to the second line of defense, i.e., from the skin and limbs to the torso, in order to protect the viscera and other vital organs. Once the blood is not functioning well, the blood cannot bring enough heat to reach the fingertips, which will cause cold hands and feet.
Why are women more likely than men to have cold hands and feet?
Cold hands and feet are also closely related to lower levels of thyroxine in the body. Thyroxine can not only promote the increase of the body’s basal metabolic rate, so that the blood circulation of the skin to speed up, so as to produce body heat to resist the cold, but also can directly affect the metabolism of estrogen and progesterone of the female ovaries, so as to stimulate the body temperature center. If the synthesis of thyroxine is significantly reduced in women, it will cause the body’s ability to protect itself from the cold to be reduced.
On top of that, women’s basal metabolic rate is 2 a 12% lower than men’s and declines with age. Once the metabolism slows down, the release of heat from the body decreases, resulting in poor circulation and leading to a more intense feeling of coldness in the hands and feet area.
Women are more prone to cold hands and feet, but also because the “sensors” in the skin are more sensitive than men. When you feel a drop in temperature, the skin receptors will be faster than men to send cold information to the hypothalamus, feedback to the thermoregulatory center, causing vasoconstriction, so that cold hands and feet.
Four tips to improve cold hands and feet
Long-term poor blood circulation, in addition to causing cold hands and feet, but also the formation of blood clots, clogging blood vessels, life-threatening.
Not only that, once the hands and feet cold, can reactively lead to the upper respiratory tract mucosa within the capillary contraction, cilia swing slower, lurking in the nasopharynx of bacteria, viruses will reproduce, induced colds, asthma and other respiratory diseases.
Therefore, to promote blood circulation, so that the hands and feet to keep warm is the key to health, may wish to try these four strokes to promote blood circulation, improve cold hands and feet!
Part 1 Appropriate exercise to promote metabolism
Studies have found that when performing low to moderate intensity exercise, the body produces 3 a 5 times more heat than when it is quiet, and the metabolic rate can increase by 48%. Sedentary office workers can choose to commute to and from work brisk walking or climbing stairs and other activities of low intensity exercise to promote metabolism and strengthen temperature regulation.
Part 2 Regularity of routine to balance the endocrine system
Maintain adequate sleep, can make the flow of blood to the skin increased, so that the skin to get more nutrients and nutrition to ensure that the body’s blood oxygen saturation is in the normal range, and can effectively regulate the body’s hormone levels, reduce the accumulation of waste products, and promote circulation.
Part 3 Get more sunshine to clear the blood and qi
Modern medicine has confirmed that our back skin contains a large number of immune cells, through the sun can activate these immune cells, to dredge the meridians, smooth blood and qi, harmonize the internal organs, dispel cold and relieve pain.
Part 4 can light red light, promote circulation
According to the relevant literature, red light therapy, known as the “medical miracle of the 20th century”, plays an increasingly important role in promoting metabolism, accelerating the regeneration of damaged nerves, anti-skeletal muscle fatigue and other clinical areas. As early as in Europe and the United States developed countries, such as Germany, Austria, Switzerland, Italy and Australia, has been widely used in red light therapy to treat and achieve good results.
Numerous references and clinical trials have also confirmed that red light dilates blood vessels and enhances cellular metabolism, thereby improving poor circulation and strengthening the body’s immunity.
Prolonged cold hands and feet and poor blood circulation not only affect daily life, but also significantly weaken the ability to fight diseases and increase the risk of disease. Promote blood circulation in a timely manner to enhance the ability to protect against the cold, is the warmth of the winter long-term solution.
