The benefits of taking a cold bath in winter
1, improve the body's cold resistance.
Taking a cold bath in winter can improve the body's ability to adapt quickly to the cold, and it is not advisable to get sick because of catching cold. When taking a cold bath, the skin of the body touches cold water, and the nerves on the skin surface are stimulated by cold, which promotes the sharp contraction of skin blood vessels and reduces the loss of body heat. However, with the constant stimulation of cold water, the body will continue to transmit energy, the skin blood vessels will expand, and the skin will train to adapt to the cold in this process. In normal times, even if the body temperature changes suddenly,
2. Prevention of arteriosclerosis
Taking a cold bath in winter can speed up blood circulation, and blood vessels can get elastic training between expansion and contraction, which is helpful to prevent arteriosclerosis. Thereby reducing many diseases caused by arteriosclerosis, such as hypertension and heart disease.
Step 3 prevent colds
Taking more cold baths can promote the blood circulation of blood vessels in the whole body and enhance the opening and closing function of skin pores. Long-term persistence can improve the cold tolerance of the body, increase the adaptability of the body to temperature, especially to cold air, and enhance immunity. At the same time, the blood will bring toxins from the viscera to the outside and promote the metabolism of the viscera, thus preventing diseases such as colds, bronchitis, tonsillitis, pneumonia and allergic rhinitis.
4. Help digestion
When cold water acts on the skin, the blood vessels of the skin contract violently, and the blood flows to the zang-fu organs or deep tissues, which can enhance the metabolic process of the zang-fu organs and increase the heat. Blood circulation in abdominal cavity is accelerated, gastrointestinal function is active, and intestinal peristalsis is accelerated, which can improve digestion and absorption ability, thus enhancing the function of the whole digestive system and greatly increasing appetite. It can strengthen the function of digestive system for a long time, and has a certain auxiliary treatment effect on chronic gastritis, gastroptosis, constipation and other diseases, but it will not be used for half an hour after meals.
5. Enhance the function of the nervous system
Stimulated by cold water, the brain will immediately get excited, mobilize all organs and tissues of the whole body to strengthen activities and resist the cold; The relaxation of blood vessels in the whole body depends on the regulation of the central nervous system. Long-term cold bath exercise can enhance the function of the central nervous system and slow down the aging and death of brain cells through nerve reflex and brain function.
6, lose weight and beauty
In winter, there is little human activity. Bathing with cold water can stimulate the body to generate more heat to resist the cold, and consume these heat, so that it will not be stored as fat, thus playing a certain role in losing weight. In addition, cold water can make blood flow to subcutaneous tissue, improve blood circulation efficiency, enhance skin nutrition, make skin young and elastic, and prevent skin diseases. .
Disadvantages of taking a cold bath in winter
1, induce dermatosis
The oil on the face and the sweat on the body will solidify after encountering cold water, which is equivalent to not washing, and may even lead to acne and prickly heat, especially sweating on the body, and sensitive skin may even become acute inflammation.
2, gynecological diseases.
Because of women's unique physiological cycle, their resistance is poor. If they are often stimulated by cold water, it will easily lead to a decline in resistance. Pathogenic microorganisms can take advantage of this situation and induce a variety of gynecological diseases, which will adversely affect women's pregnancy and health.
3, joint pain.
Once the cold enters the body, it is easy to get cold hands and feet. Over time, it is prone to joint pain, general weakness and other symptoms, especially for women with slightly weak resistance.
4, cause heart disease
Taking a bath with cold water will cause a series of stress reactions, such as rapid heartbeat, high blood pressure, muscle contraction and nervous tension. For example, people with poor heart function can excite the body's α adrenergic receptors after taking a cold bath, causing systemic arteriole contraction, increased cardiac ejection resistance and increased myocardial oxygen consumption. Being in this state for a long time is very unfavorable to heart health.
Can you have a fever by taking a cold bath in winter?
It varies from person to person.
Some people are strong, exercise for a long time, and take a cold bath all year round without having a fever. Some people are in poor health and don't exercise at ordinary times. Taking a cold bath in winter will catch a cold, and when the cold is serious, you will have a fever. Therefore, people with poor resistance should not try to take a cold bath on a whim, but take a cold bath in the right way to avoid adverse consequences.
