Spending just 20 minutes each day immersed in a book or article is more than a simple pleasure—it’s a proven way to protect your mind. Research published in JAMA Psychiatry revealed that regular reading can slash dementia risk by up to 40%. This is because reading activates several areas of the brain at once, fostering connections that help preserve cognitive function as we age. Read the study here.

2. How Reading Stimulates the Brain

When you read, your brain is anything but passive. Language processing, memory retrieval, and imagination all come alive, lighting up different neural pathways. MRI scans of avid readers reveal stronger neural connectivity—these robust connections are thought to create a cognitive “reserve” that shields against dementia’s effects. According to a recent review, this mental stimulation is key in slowing cognitive decline and keeping the mind resilient as we grow older.

3. Fiction vs. Nonfiction: What’s Best?

Whether you prefer novels or biographies, both fiction and nonfiction offer cognitive benefits. However, reading fiction may provide extra perks by boosting empathy and social cognition, as noted by Psychology Today. Immersing yourself in different genres keeps your brain challenged and engaged. Mixing up your reading list is an easy way to maximize the brain-boosting effects of this daily habit.

4. Audiobooks Count Too

Don’t worry if you prefer listening to stories—audiobooks deliver similar cognitive benefits as reading words on a page. Research from the University of California found that listening to audiobooks activates many of the same brain regions, making it a smart alternative for people with vision challenges or packed schedules. Whether you’re reading or listening, your brain stays stimulated and engaged, supporting long-term cognitive health.
