A Neuroscientist Reveals the Number 1 Habit Shared By Happy and Successful Women
Jasmine PanayiotouNeuroscientist Siti Atinna Fadillah explains why putting pen to paper is one of the most life-altering things a woman can do.
We spend an average of 8.8 hours a day staring at screens, consuming, scrolling, reacting, and repeating. And somewhere in that mindless loop, most of us are in a constant state of burnout and dysregulation, having lost the thread back to ourselves without even realising it. So in the digital age, it begs the question how we can disconnect from our feed and reconnect with what's real?
What is The No: 1 Female Habit?
According to Neuroscientist Siti Atinna Fadillah, journaling is one of the simplest ways, not because it's an 10000 year old habit, but because the neuroscience behind it to this day is genuinely difficult to argue with.
How Does Journaling Really Work?
Neuroscientist Siti Atinna Fadillah says journaling works because it externalises internal chaos.
"Expressing emotions activates the prefrontal cortex, the brain region responsible for cognitive control and emotional regulation, while reducing activation in the amygdala, which is central to fear and anxiety," she explains.
"This neural shift helps the nervous system move from a state of threat into one of safety." Writing your feelings down isn't just cathartic; it has been shown to physiologically calm your nervous system, and that distinction matters more than most people realise.
A more modern name for journaling is 'brain dumping', defined as 'externalising thoughts, tasks, and worries onto paper to relieve overwhelm, clear brain fog and improve memory.'
What's The Most Effective Way To Journal?
There is a meaningful difference between typing and writing by hand that goes considerably deeper than aesthetics. Siti Atinna Fadillah says handwriting engages sensorimotor networks in the brain, slowing cognitive processing and allowing emotions to be felt rather than bypassed.
Research by Mueller and Oppenheimer (2014) found that writing by hand is linked to deeper encoding, greater reflection, and stronger emotional integration than typing, which may explain why journaling by hand so reliably reduces the physical symptoms of anxiety: the muscle tension, the racing heart, that low-level hum of dread that so many women carry throughout the day.
What Are The Science-Backed Benefits?
Long-term studies on expressive writing show improvements not just in mental health, but in physical health. The majority who partook in journalling experienced reduced stress symptoms and better immune function (Pennebaker & Chung, 2011). Self-reflective journaling also deepens interoceptive awareness, meaning one's ability to physically and emotionally regulate (Craig, 2009).
For women especially, this matters. Here's how.
The Women Who Swear By It
Oprah Winfrey
Between 1996 and 2006, Oprah Winfrey kept a daily gratitude journal and didn't skip a single day, listing five specific things she was grateful for each morning, every morning, for an entire decade. On reflection, she said it played a huge part in maintaining a positive outlook on life at a time whenshe was building one of the most powerful media empires in history.
Susan Sontag
Successful American writer Susan Sontag, one of the most influential intellectuals of the twentieth century, described her journals as a space not simply to express herself, but to create herself. She said her journal ended up being a more powerful asset than any self-help book she ever picked up.
Virginia Woolf and Joan Didion
Fiction and non-fiction pioneers Virginia Woolf and Joan Didion both kept lifelong journals, a practice each credited with helping them find the voice that ultimately defined their work and the legacy they left behind.
And more recently, Samira Far, who founded celebrity nail empire Bellacures at 22 and built it into a multi-location business, writes in a journal for five minutes every morning before engaging with the world.
"It's important to connect with myself before I go out into the world," Far has said, spending just five minutes every morning putting her thoughts on paper to mentally declutter and show up with a clear head before the day begins.
What Are The Other Benefits?
Beyond the neuroscience is something harder to quantify: the feeling of coming back to yourself. When thoughts are witnessed on paper rather than carried internally, the brain finds relief. And in the world we live today, sitting down with a notebook is a quiet act of resistance that most of us are long overdue for.
How Long Should You Journal For It To Work?
Not long. Research suggests that even ten to fifteen minutes of expressive writing three to four times per week is enough to produce measurable improvements in mood, clarity, and stress levels.
The Science Behind Writing Messy:
What nobody tends to tell you about journaling is that the most revealing entries are the ones that make the least sense. Where the handwriting deteriorates because the feeling got too big, the ink smudges, where you contradict yourself mid-sentence and don't bother going back to fix it.
The science behind this is straightforward. When you write neatly, your brain is working overtime to focus on the aesthetics of the page. This leaves significantly less mental bandwidth for the actual processing of emotion, making the ritual itself rather pointless.
Writing messily removes those constraints entirely, freeing your brain to offload raw thoughts directly onto the page. It also quiets the analytical left hemisphere of the brain, which is preoccupied with logic and order, and allows the more intuitive, emotional right hemisphere to surface the thoughts you would otherwise unconsciously censor.
Dr. James Pennebaker, a pioneer in expressive writing research, found that writing down raw, unfiltered emotions lowers activity in the amygdala and reduces cortisol levels, meaning the messier and more honest the entry, the greater the physiological relief.
In other words: perfectionism is the enemy of the whole exercise.
Where Should You Start?
Here are some questions to consider writing the answers to.
How am I actually feeling right now — not how I think I should feel?
What have I been carrying this week that I haven't said out loud?
What does my body need today that I haven't given it?
