For twelve years, 3,635 Americans over 50 were followed to see who was still alive. Those who read books had a 20% lower risk of dying over that time than those who read none, and the edge showed up at about half an hour a day. By one measure, the book readers lived almost two years longer.
That's a link, and part of it ran through sharper thinking. Still, it's a lovely reason to pick up the book on your bedside table. Ahead: seven benefits of reading, what a novel does for your sense of other people, the famous stress number that falls apart when you look for its source, why the tablet in bed costs you sleep, where paper still beats a screen, and whether audiobooks count.
1. A sharper mind for longer
Reading keeps your brain busy: following a plot, holding the characters in mind, picturing a place you've never been. In 294 older people tested every year for about six years, those who did more mentally stimulating things, reading among them, lost memory and thinking skills more slowly. That held even after the usual damage of ageing in their brains was taken into account. The habit counted in childhood and middle age, too.
The protection may reach as far as dementia. In 469 people over 75 followed for about five years, reading was one of four pastimes linked to a lower risk of dementia, along with board games, playing an instrument and dancing. The link held even after leaving out people who may already have been in the early stages.
It may start paying early. In more than 10,000 American children on the edge of their teens, those who had begun reading for fun in early childhood did better on thinking tests, had fewer mental health problems and had larger areas of the brain linked to both, even after allowing for family income. It's a link, and a gentle nudge to start young.
If your child is a bookworm, send them outside too. Across more than 25,000 children, more time on close-up work such as reading went with slightly higher odds of short-sightedness, and time outdoors cut the risk of it starting by more than 40%.
Keep a book where you'd otherwise reach for your phone: by the kettle, in your bag, on the sofa. If you have children, read with them, and let them pick the book.
2. A window into other minds
Fiction lets you live inside someone else's head for a while. When 14 sets of experiments were pooled, people who read fiction did a little better afterwards at reading other people's thoughts and feelings than people who read nonfiction or nothing at all. The effect is small, and it held up.
It works best when you lose yourself. Readers who were swept up in a story grew more empathic over the following week, and readers who stayed detached grew slightly less so. Nonfiction moved neither group.
Even a boy wizard can help. In one experiment with Italian primary-school children, reading Harry Potter warmed their attitudes toward groups often treated unfairly, such as immigrants, most of all in children who identified with Harry.
Pick a novel told by someone whose life looks nothing like yours.
3. A calmer mind
You've likely seen the claim that six minutes of reading cuts stress by 68%. It comes from a 2009 test run by a consultancy and reported in the press, and we couldn't find it in any scientific journal.
The real picture is gentler. Health students who spent 30 minutes reading saw their blood pressure and heart rate fall, as much as after 30 minutes of yoga or of humour.
A book can help with more than a bad day. Self-help books built on proven talking-therapy methods eased low mood in adults, and the lift was still there up to three years later. In young people, the results were less clear. David Burns's is the best-known book of its kind.
It's an old idea. According to the Greek historian Diodorus, the room where Egypt's King Ramesses II kept his books bore the words "the house of healing for the soul". The modern name, bibliotherapy, arrived in 1916.
When the day has been loud, swap the scrolling for half an hour with a book.
4. Better sleep, with paper
Reading before bed helps you wind down, and the format matters. When people read on a light-emitting tablet for several evenings before bed, they took longer to fall asleep, made less of the sleep hormone melatonin, shifted their body clock later and felt less alert the next morning than when they read a printed book.
A weak lamp is safe for your eyes, too. The old warning that reading by one ruins your sight has no evidence behind it. Dim light can tire your eyes for a while, and the strain passes once the light improves.
Keep a paper book by the bed and leave the tablet in another room. A clip-on lights the page with a warm glow that keeps blue light low.
5. More words, better sentences
Every book teaches you words without trying. When 20 experiments were pooled, readers picked up about 15% of the unfamiliar words they met, just from the sentences around them. Read enough and that becomes a vocabulary, and you start to hear what a good sentence sounds like.
Books carry words that everyday talk rarely uses. Even picture books for small children hold more rare words, ones outside the 5,000 commonest in English, than adults use when talking to children, or even to each other. Reading aloud hands a child words they'd seldom hear.
With young children, make the book a conversation. When parents of children aged one to six were shown how to share picture books, by pointing, asking questions and talking about what they saw, the children's speech and understanding grew, and the more sessions they had, the bigger the gain.
When a word stops you, guess its meaning from the sentence first, then look it up.
6. Deeper understanding, on paper or by ear
For learning, paper still has the edge. Across 54 comparisons with more than 171,000 readers, people understood factual texts better on paper than on a screen, more so when they were short of time, and the gap grew between 2000 and 2017. For stories, the screen held its own. Maryanne Wolf's looks at what screens are doing to the reading brain.
Through most of history, reading meant hearing. Saint Augustine thought it worth recording, in the 4th century, that Bishop Ambrose read in silence: "his voice and his tongue were at rest." Reading aloud was the custom, and a silent reader was a curiosity.
Augustine's world had a point. Words you read aloud stick in memory better than words read silently, and hearing your own voice beats hearing someone else's. When something needs to stay with you, say it out loud.
Listening counts, too. Adults who took in the same nonfiction chapter as an audiobook, on a tablet or both at once understood and remembered it equally well, straight after and two weeks later. In brain scans, the map of word meanings looked almost the same whether people read a story or heard it.
To keep what you read, close the book and test yourself. When ten common learning habits were weighed up, testing yourself and spreading your reading over several sessions came out on top. Rereading and highlighting, the two that students lean on most, came near the bottom.
Print the report you need to understand, or get the book version of the subject you're learning.
7. A longer life
Back to those 3,635 readers. Books did more for them than newspapers and magazines, and the more they read, the bigger the edge. The link held after allowing for age, education, wealth, health and low mood. It may still reflect the kind of person who reads, and the habit costs little either way.
Make it a habit
Daily reading for pleasure is slipping. Across 236,000 Americans surveyed between 2003 and 2023, the share who read for fun on a given day fell by about 3% a year, and the gap widened for people with less education and lower incomes.
Pick a time you already have, such as the half hour before bed or the train home, and keep the book within reach. Follow what you enjoy. An audiobook turns the commute, the walk or the washing-up into reading time, and paper is best for the hard, factual books. Putting down a book you're not enjoying is allowed, and it makes room for the next one.
Speed-reading apps promise to double your pace. A close look at how reading works found a trade-off: the faster you go, the less you understand. The way to read faster and still follow every line is to read more and grow your vocabulary.
If reading has always felt like hard work, it may be dyslexia, which affects about 3 to 7% of people and can be assessed at any age. In the meantime, audiobooks give you the same story and the same understanding.
Choose your next book tonight and leave it where you'll see it in the morning.

Frederick Douglass was an enslaved boy when his mistress began teaching him the alphabet. Her husband stopped the lessons, warning that reading "would forever unfit him to be a slave." Douglass wrote: "From that moment, I understood the pathway from slavery to freedom."
"Library" comes from the Latin liber, the inner bark of a tree, a word that came to mean "book". The inner bark feeds a tree as it grows, and a reading habit does something similar for you. It sharpens your mind, widens your view of other people, calms your evening, protects your sleep and grows your words. Over a lifetime, it may even add time to it.
The readers in that twelve-year follow-up needed only about half an hour a day. Tonight, one chapter, on paper, in bed. See how you sleep.
