1. Can you lose weight by taking a cold bath?
From a scientific point of view, it should be invalid. It is harmful to human body and skin. Conversely, it is reasonable to take a hot bath. In the case of taking a cold bath, tighten the pores, and the dirty things inside cannot be removed with sweat. Although the skin feels smooth after washing, it is entirely because the pores of the skin shrink, which will eventually affect the skin. If you can't sweat a lot, it will easily cause edema. So my legs are uncomfortable.
It is recommended that you take a bath with boiling water with appropriate temperature before meals every morning. Promote basal metabolism and accelerate the discharge of sweat, but people generally don't have enough physical strength before meals in the morning, and taking a hot bath is also a very expensive thing, so they can only maintain it by consuming fat, and achieve the goal of losing weight from the above two points.
"Some overseas institutions have done relevant scientific research. Brown adipose tissue has different specificity at different temperatures. At ultra-low temperature, brown adipose tissue may be activated. " With the increase of physical exercise and exposure to strong cold air, brown fat may be stimulated or its composition increased. But at present, this kind of scientific research data information is only used in clinical experiments, and it is not certain whether it has the same or similar actual effect in vivo. In clinical experiments, the use of some growth hormones will stimulate brown fat or enhance its body composition, but in fact, the body will gain weight after applying growth hormones.
Therefore, the name of losing weight by taking a cold bath alone is not acceptable to everyone.
Second, the benefits of taking a cold bath.
improve immunity
Cold water bath can improve the body's resistance to diseases, which is called "vascular gymnastics". When taking a cold bath, the skin surface will turn white because of cold water for the first 1 to 2 minutes, and blood will flow to the depths of internal organs. But after washing for 2 to 3 minutes, the blood will be distributed, and the blood will flow back to the surface of the skin, and the skin will turn red slowly. The whole process is like doing vascular gymnastics.
Fever and cold are not easy.
People with poor immunity can take more cold baths to improve their cold tolerance and immunity. If blood is supplemented, it will flow to the viscera, which can carry endotoxin from the viscera and promote the basic metabolism of the viscera.
Calm nerves, help sleep and wake up.
Rapid heartbeat, dry mouth and thirst can lead to autonomic nerve imbalance. Taking a cold bath can make autonomic nerves not excited, which is helpful to soothe the nerves and help sleep. In addition, under the stimulation of cold water, the human brain will get excited immediately, stimulating the internal organs of the whole body to promote activities to resist the cold; The whole body vascular left ventricular fitness exercise depends on the control of the central nervous system, and long-term adherence to cold water bath exercise can enhance the function of the central nervous system and alleviate the decline and death of the cranial nerves according to nerve reflex and human brain efficacy.
Third, the disadvantages of cold water bath.
What are the disadvantages of taking a cold bath for a accustomed basin friend?
1, I like to wash my hair with cold water in summer, which can cause headaches or chills in winter. Therefore, avoid washing your hair with cold water in summer, and dry your hair immediately after washing. It is also forbidden to blow the air conditioner on the electric fan or central air conditioner for a long time immediately.
2. You can't take a bath with cold water just after exercise or fitness exercise. Because the body is still in a state of vigorous metabolism, rising melting point and telangiectasia of the skin, if you take a cold bath immediately, the skin will be stimulated by cold water, which will lead to vasoconstriction of the skin according to nerve reflex. In this way, sweating and heat exhaustion will be hindered, but it will make heat exhaustion difficult and body temperature rise. In addition, the reduction of skin blood volume suddenly increases the strength of returning to the heart, which will increase the pressure on the heart.
3. Inadvertent cold water bathing in summer will lead to the accumulation of moisture in meridians of cold syndrome, which makes people very prone to various joint pains, numbness of limbs, rheumatism, rheumatoid arthritis, traumatic joint pain and so on. It usually happens in cold weather and subsides in hot weather.
4. Because of its unique physiological reasons, especially during the physiological period, lactation and pregnancy, being stimulated by cold water when bathing with cold water will cause endocrine disorders, amenorrhea and abdominal pain, and many germs will also enter the vagina to cause gynecological diseases such as vaginitis, which will have a certain impact on women's pregnancy and health.
You can't take a bath with cold water when you are drunk. After drinking and sweating, the glucose in the human body is converted into calorific value, which greatly reduces the blood sugar value and body temperature. The alcohol contained in wine can inhibit all normal activities of the liver, and even hinder the repair of glucose storage in the body, so that blood sugar is not worth timely and reasonable supplementation. This is very prone to dizziness, headache, dizziness, general weakness and other symptoms, and even more serious, blood sugar coma will continue. Therefore, after drinking and sweating, you can't take a cold bath immediately to prevent distress and seriously endanger your health.
