More exercise leads to more youthful arteries

According to US research exercising two to three times a week (30 minutes per session) over a lifetime led to more youthful middle-sized arteries supplying blood to the head and neck.

Though, people who exercised four to five times per week - roughly the amount recommended by NHS guidelines - had healthier large central arteries as well as healthier middle-sized ones.

They said the larger arteries are the ones that supply blood to the chest and abdomen.

However, the research did not take into consideration factors such as diet, social background and education in their analysis which would also have had an impact.
