Curious Kids: why does reading in the back seat make you feel sick?

Why does reading in the back seat make you feel sick? – Jane, aged 10, from Coburg North, Australia.

Hi Jane, your question about why reading in the back seat makes you feel sick is a very good one. The answer has to do with our eyes, our ears and our brain.

Reading in the back seat can make you feel sick because your eyes and ears are having an argument that your brain is trying to settle!

Curious Kids: Why do our ears pop?


When you’re reading in the back seat, your eyes see that your book is still. Your eyes then tell your brain you are still.

But your ears feel the car is moving. Your ears then tell your brain you’re moving.

How can your ears tell you’re moving?

Your ears don’t just hear, they help with your balance too.

Your ear has three main parts:

  • the outer ear is the bit you can see on the side of someone’s head
  • the middle ear is your eardrum and some tiny bones and muscles
  • the inner ear is the part of your ear that can help with your balance.
The ear includes more than what you see on the outside.

Your inner ear contains cells that have hairs sticking out the top. Scientists call these “hair cells”.

Some of these hair cells help us to hear. When sound hits those hair cells, the hairs move and the cells send signals to the brain. Our brains use those signals to hear.

Other hair cells help us to keep our balance. When the car we’re sitting in moves, that movement makes the hairs on those hair cells move too, and they send different signals to the brain. Our brain uses those different signals to tell we’re moving.

Why doesn’t the brain like this?

Some people’s brains don’t like it when their eyes say they’re still but their ears say they’re moving.

When eyes and ears argue like this, the brain can think that something dangerous might be about to happen.

If this happens, the brain can get the body ready to fight or run away (scientists call this the “fight or flight” response).

The conflict between our eyes and ears make the brain think something dangerous might happen.

One of the things the brain can do is take blood away from the stomach to give to the muscles.

Giving blood to the muscles can help us to fight or run away. But taking blood away from the stomach can make us feel sick.

What can you do about it?

If reading in the back seat makes you feel sick, you might need to settle the argument between your eyes and your ears.

One way to do this is to stop reading and to look out the car window. This could help your eyes to tell your brain that you’re moving as you see the world whizz by, and your ears to tell your brain that you are moving as you feel the car moving.

But this suggestion won’t work for everyone. Some people will still feel sick when they ride in a car, even if they aren’t reading.

This is because while our eyes and our ears help us to balance, so do our skin and our muscles. This creates many opportunities for arguments that our brain has to settle!

LIFE AT THE BOOKSHELF: A Life Around Books


I have spent a lot of my time around books. I love books. I can’t have enough books – at least it certainly seems that way. I’m always on the lookout for books. I don’t buy a lot of new books these days, however, if there is a good one – well, I just have to buy it.

I’ve always read a lot. Early in life I probably read more out of necessity in order to pass subjects and exams. It wasn’t until I left school that I really got a passion for books. What spurred my passion for books was my growing interest in Christianity and my subsequent embrace of it. I just wanted to learn and to learn as much as I could. So I started to buy books

Somewhere along the track I became interested in reading books of other subjects as well, especially books to do with history. I also read novels, but for me to read a novel it has to have a great plot. One of my favourite authors is Tom Clancy, which probably gives you some idea of the type of novels I read.

Of course I collected books on horticulture (I trained as a horticulturist), cooking, computers, travel, wilderness and other areas that I was interested in. However my real passion in books has always been theological and historical.

At the moment my life is in a ‘treading water-like’ situation. I’m probably still another 6 months away from moving into another home to rent (I currently live in a caravan park in a cabin), so the vast majority of my books are in storage and I can’t get at them because they are quite some distance away and I don’t have a car. There probably isn’t a day that goes by that I wish I had access to some book or another. I am longing for the day when I’ll be able to make use of all my books again.

I’ve probably managed to collect another couple of boxes of books in the time I have been away from them and I am slowly accumulating a collection of them in the cabin. They are enough to get me by at this stage, but my various interests are crying out for the books to assist me in them.

I have begun to place a listing of the books I own on my web site at particularbaptist.com and will eventually add them to my Shelfari presence as well. A look at the list (which is nowhere near complete) soon gives an idea of the number of books I have.

See the list at:

http://www.particularbaptist.com/kevins/kevinslibrary.html

See my Shelfari Profile at:

http://www.shelfari.com/particularkev

I have also started accumulating books online at both the particularbaptist.com website and the Kevin’s Family – History Site. These two virtual libraries encapsulate the two main areas of my passion for books – theology and history.

It is for these two libraries (other than my own interest of course) that I am buying out of copyright theological and historical books. Gradually I am building up my collection of online books in these libraries, sharing my passion for books and the wealth in books with a much wider audience.

Visit the libraries at:

http://particularbaptist.com/library/libraryindex.html

http://particularbaptist.com/matthewshistory/library/articles.html

Not only do these libraries contain the works that I have collected and put online, they also have many links to others works that others have placed online. In short, these two virtual libraries have an enormous amount of resources in them – enough to keep the most avid reader going for a life time.

I have now started the ‘At The BookShelf’ Blog and the ‘Reformed Reading Group’ at Shelfari to provide another aspect to sharing my passion for books, especially in the two areas I have mentioned – theology and history. With these two latest sites I will be able to interact with visitors and discuss various books, what we have learnt, questions and issues raised, enjoy fellowship, etc. So I am really hoping that my visitors will join the Reformed Reading Group (I am thinking especially of Reformed Christians here obviously – though others are most welcome) and get involved in the discussion, as well as having visitors interacting via the comments provision here at ‘At The BookShelf.’

Visit the Reformed Reading Group at:

What I intend to post here in the Blog are reviews of the books I have read and possibly some quotes from some of the books also. I will probably also be posting URLs for new books (old books) I post in the two virtual libraries also.

What else is left to say but please get involved at some of the sites I have mentioned? You won’t regret it.
