Boost Circulation
For many people, soaking the whole body in cold water can be uncomfortable. This may be because the body needs to work harder to keep the body temperature stable. However, low temperature from the surrounding environment can help boost blood circulation. This means taking cold showers regularly could help the circulatory system become more efficient. Many people report that the skin becomes much better when they practice this activity as their daily routine. This effect can especially benefit athletes in healing an injury. When soaking the body in cold water, warmblood may be transported to the whole body, thus speeding up recovery and reducing inflammation. Other people can benefit, including those with diabetes, high blood pressure, and poor circulation. [4]
Improve Hair and Skin Health
There is no comprehensive scientific evidence on the effect of cold water on hair and skin. However, many anecdotal proofs suggest positive effects of this activity. Low temperature from cold water can constrict and tighten the blood flow, thus making the skin look healthier and glower. Also, the cold water could close and strengthen hair cuticles. Unlike hot water, cold water does not dry out sebum layers, which work as a lubricating barrier to protect the hair and skin. [5]
