Why does reading makes us sleepy?

Reading can be an almost hypnotic action characterized by rhythmic eye movement, a relaxed physical position and a focused attention. When you’re in this state, your body becomes passive and your alertness decreases unless the topic that you’re reading requires you to use your mind like mathematical calculations, deductive thinking, reasoning etc. in this way, your body easily gets tired thus resulting in sleepiness.
It may depend on the book that you are reading. Most of the time, the reason why we feel sleepy everytime we read a book, is because the topic might not be interesting to us. Boring materials can make you feel tired and make your eyesfeel a bit heavy causing fatigue and alerts your body to get some sleep. However, when you’re reading a book of your choice, your whole focus and attention is on the story. You’re looking forward to what going to happen next and you get excited.Our posture contributes a lot to how we can focus on reading and avoid getting sleepy.
