Whenever I read a book, I start feeling sleepy after a while no matter how interested I am in the topic. I have also heard others to have similar experience. Why does this happen?

As we are getting new informations/data while reading a book , our brain starts processing the acquired information into memory hence making new connections in our brain relevant to it. This process overtime makes your brain tired which makes your body feel sleepy . Actually this sleepy feeling might signal us that our brain has been overwhelmed by the information received from the book and it’s time for the brain to take some rest.
