28. Walking can raise your levels of good cholesterol
When people hear the word cholesterol, they immediately think of heart attacks and strokes. Cholesterol can contribute to such potentially fatal events. However, there are two types of cholesterol. Commonly known as good and bad cholesterol, it is the presence of bad cholesterol that can cause heart attacks and strokes. The medical term for bad cholesterol is LDL (low-density lipoprotein).
It accumulates as fatty deposits in the veins and arteries and restricts or blocks the flow of blood to and from the heart. The correct term for good cholesterol is HDL (high-density lipoprotein). HDL travels through the body removing LDL from the bloodstream. The HDL absorbs the LDL and takes it to the liver where it gets destroyed. Physical activity such as walking increases the flow of HDL around the body. The HDL is better able to find and absorb the LDL and get it to the liver.
