Salt is basically sodium chloride. It is important for various bodily functions such as transmitting nerve impulses, digestion, etc. However, too much of something is never good.
Firstly, when too much salt enters our blood, the water content in our blood rises, increasing the volume of blood. As a result, our heart works harder than usual. Secondly, as more blood flows through the blood vessels, it puts strain on their walls. Overtime, this causes the walls to grow thicker, narrowing the vessels and thus, increasing our blood pressure. In addition to this, narrowing of blood vessels means less oxygen and nutrients get transported to the cells, increasing the risk of dementia, stroke and heart attacks. Lastly, to remove excess salt, our kidneys use more water and we urinate more frequently, thus leaving us dehydrated and thirsty.
