We usually use warm water when taking a bath. If it is too cold or too hot, we will feel uncomfortable. But if you are healthy, you can actually try cold water bath, that is, take a bath with cold water between 5 ℃ and 20 ℃, which is good for your health.
prevent colds and strengthen physique: long term bathing with cold water can exercise all parts of the body. The body’s ability to resist cold has been greatly improved, and its constitution has also been greatly enhanced, which can effectively prevent the invasion of cold.
prevention and treatment of respiratory diseases: when we take a cold shower, we will find that when cold water contacts the skin, we will unconsciously take a deep breath, and then pause for a few minutes before taking a deep breath. In fact, this can inhale more oxygen and exhale more carbon dioxide, which is very effective in preventing respiratory diseases.
enhance cardiovascular function: when taking a cold water bath, cold water irritates the skin, rapidly constricts the subcutaneous capillaries, makes blood flow to the heart, and accelerates the heartbeat, thus increasing the blood flow of the whole body. Over time, the function of the heart is effectively enhanced. At the same time, the contraction and relaxation functions of blood vessels in the whole body are effectively improved under the stimulation of cold water.
improve digestive function: as the blood circulation in the abdominal cavity is strengthened and the intestinal peristalsis is accelerated when taking a cold bath, it can effectively improve the ability of digestion and absorption. Thus, it is beneficial to the digestion and absorption of food and the unobstructed stool, and has a certain therapeutic effect on indigestion and constipation.
Slimming and fat burning: researchers in Scandinavia found that low temperature can accelerate the metabolism of body fat by 15 times. If you keep bathing in cold water for a long time, you can have a good slimming effect within a year.
improve mood: take a cold bath every morning, which helps to improve your morale. When cold water comes into contact with the body, the breathing will intensify to cope with the sudden cold. This is because the body is increasing its overall oxygen intake to improve its alertness. At the same time, under the stimulation of cold water, various organs of the body will wake up completely from sleep and play an uplifting role.
improve the nervous system: when cold water stimulates the human body, the brain is in a highly excited state, and the nerves of the whole body are in a “battle ready state”. When the cold water bath is stopped, the nervous system returns to a relaxed state. This repeated exercise effectively improves the function of the nervous system.
promote the recovery of physical function after sports: athletes always take an ice bath after high-intensity training to reduce physical pain. You don’t have to take a bath in ice water, but a quick cold shower after physical training has similar effects. Maybe it won’t be so painful to take a cold bath after running, pick up a pencil or go upstairs.
