Why Does Reading Make You Sleepy?
Most people enjoy reading a good book after a long day or over the weekends. However, do you ever notice how you start feeling sleepy three pages into a book no matter how exciting it is? If you can relate to this, you are not alone. So what is it about reading that can make us conk out?
The act of reading requires regular eye movement as your eyes follow the words across the page. It also requires brain power as your brain interprets the letters your eyes see and converts them into meaningful words, sentences, and paragraphs. As your brain works hard and your eye muscles tire, it's only natural that they would need rest, leading to eyes slowly closing and sleep taking over. The concentration required to process every word can be pretty exhausting, too, especially if your chosen tome is dense. And reading line after line of anything can make you feel like giving your eyes a break.
The environment you create could be a big reason. People generally create a cosy and comfortable atmosphere that is quiet while they read. Experts say these are the very same conditions that are perfect for sleep. Reading is also a great way to escape from all your troubling thoughts as it helps you put your mind at ease. Reading is one of those activities that can be enjoyable and relaxing, which can help to put the mind and body in a calm state. This calm state can cause you to feel sleepy.
If you have a book that you really need to finish or you simply want to read longer without falling asleep, there are some techniques you can use. First, find a place to read that's comfortable, but not too comfortable.
Rather than lying down on your back, sit up in a comfortable chair, so you don’t feel like drifting off to sleep. Use lighting to reduce eye strain. Also make sure that the temperature isn't too hot. Reading in an environment that's too warm can make you sleepy.
If you anticipate trouble staying awake and you really need to finish that book before bed, try waking yourself up before you start reading. Do some light exercise, drink a caffeinated beverage, or take a cool shower. If you're more alert when you start reading, you're more likely to make it to the end of that book!
