Among the activities listed, reading a book is the least beneficial for a healthy respiratory system. While reading itself is a good mental exercise and can be relaxing, it does not actively engage the respiratory system in the same way that physical activities like walking around the mall, riding a bike, or walking the dog do. Those physical activities promote better lung function and overall cardiovascular health through increased breathing and circulation.
