How does a high blood pressure sufferer fare while taking a cold shower?
Studies have shown that the cardiovascular system undergoes certain alterations as a result of taking a cold water bath. It has been scientifically shown that when cold water contacts the skin and parts of the body’s external limbs, a restriction of the surface blood circulation occurs. As a result, the deeper tissue blood circulation speeds up and the optimal body temperature is maintained.
According to healthline While this is occurring, it has beneficial effects on the cardiovascular system, promotes long-term heart health, and helps lower blood pressure. For this reason, cold showers are recommended for those who suffer from high blood pressure, since they have the opposite effect of hot showers on the body’s ability to regulate blood pressure.
