in hot summer, shower has become one of the effective methods for everyone to relieve heat and cool down. Shower has other benefits in addition to relieving heat and cool down. The US “medical daily” recently published an article on the “seven benefits of bathing” confirmed by scientific research.
1. Improve vigilance.
shower with cold water in the morning, the body is stimulated, and then naturally take a deep breath, which can increase the oxygen intake in the body, accelerate the heartbeat, promote the blood circulation of the whole body, warm the body, and feel refreshed and full of energy all day.
2. Improve hair and skin health.
hot water bath will cause dry skin, while warm water bath can tighten skin, shrink pores and prevent blockage. In addition, warm water bath helps to “seal” skin and scalp pores and prevent dust from entering. Dr. Jessica crant, a dermatologist in New York, said that cold or warm water can also help prevent the skin from losing the protection of natural oil too quickly. In terms of hair care, cold water shower is beneficial to hair follicle health, making hair brighter and healthier.
3. Improve immunity and promote blood circulation. Dr. Joseph mclara, an American natural health expert, said that taking a shower can more effectively stimulate the ability of arterial blood pumping, improve the overall health of the heart, increase the blood flow of important body organs, promote blood circulation, help reduce blood pressure, prevent arterial obstruction and improve the immune system.
4. Good for weight loss.
the Jocelyn diabetes center affiliated to Harvard Medical School found that the body fat was divided into two types: white and brown. The former is harmful fat, the latter is good fat, which can produce energy to keep the body warm, and can be activated when the body is cold. Therefore, taking a shower helps to promote brown fat activities, help the body consume more calories, and if you stick to it for a long time, you can lose 4kg a year.
5. Relieve muscle soreness and accelerate recovery after exercise.
a study by Ulster University in Northern Ireland found that taking a cold bath after exercise can relieve muscle pain. The study involved 17 related studies and 360 participants. The results show that after resistance training, cycling or running, taking a 24 minute cold bath (water temperature 10 ~ 15 ℃) can effectively alleviate the symptoms of muscle soreness 1 ~ 4 days after exercise.
6. Reduce pressure.
a study found that uric acid levels in subjects decreased significantly after shower stimulation. In addition, the antioxidant (glutathione) is at the best level, which can also increase the level of other antioxidants. These help relieve stress and enhance tolerance to stress and even disease.
7. Alleviate depression.
shower can strongly stimulate the “cold receptor” in the skin, making the peripheral nerve endings send a large number of electrical pulse signals to the brain, so as to improve mood and alleviate depressive symptoms. A study found that “cold bath therapy” also has analgesic effect, without obvious side effects and dependence. The therapy includes 1 ~ 2 cold water baths (water temperature 3 ℃), 2 ~ 3 minutes each time, and 5 minutes of rest in the middle.
