3. Improves Immunity and Circulation
Cold water can improve circulation by encouraging blood to surround our organs, which can then help combat some problems of the skin and heart. As cold water hits the body, it’s ability to get blood circulating leads the arteries to more efficiently pump blood, therefore boosting our overall heart health, according to Dr. Joseph Mercola, a natural health expert. It can also lower blood pressure, clear blocked arteries, and improve our immune system.
4. Stimulates Weight Loss
Cold showers can aid weight loss in an unexpected way. The human body contains two types of fat tissue, white fat and brown fat. White fat is accumulated when we consume more calories than our body needs to function, and we don’t burn these calories for energy. This body fat piles up at our waist, lower back, neck, and thighs, and is the one we all struggle to eliminate. Brown fat is the good fat, which generates heat to keep our bodies warm, and is activated when exposed to extreme cold, according to the Joslin Diabetes Center, a Harvard Medical School affiliate. Thus, cold showers can promote brown fat activity.
A 2009 study found that exposure to extreme cold temperatures activated brown fat in 23 and 24 participants by a 15-fold increase, meaning someone could lose up to nine pounds in a year if they kept this practice up.
