The majority of us have much too much trash in our brains.

Stress. Regrets. Fears.

Annoying tiny voices that never stop talking. Some drink it away. Some people’s eyes burn from scrolling through Instagram. Me? I grabbed a notebook.

And yes, I am referring to journaling before you roll your eyes.

Writing “Dear Diary” about a crush who never texted back is something you may have done when you were thirteen.

Now that I’m a grownup, I’ve discovered something startling: writing things down can alter not only your thoughts but also your health.

I mean practically everything, including your immune system, blood pressure, and the number of sick days you take at work.

Doesn’t that sound dramatic? Stay with me.

Science claims that writing is one of the most inexpensive and underappreciated tools available for mental and physical health, and I’ll tell you what happened when I resumed writing after years of neglecting it.

Why I Even Bothered to Journal Again

Anne, a friend of mine, stood up in our mastermind group this year and started talking about how journaling helped her keep her sanity.

She made it seem almost magical: less stress, more clarity, and a method to eliminate all the noise in her thoughts.

Writing in a journal? Seriously? I used to do it when I was a tteenager writing about my heartbreaks in ua messy way

But I hadn’t used a notepad for anything other than grocery lists in years. Still, the way Anne talked about it bothered me. She seemed more at ease.

More stable. She said she was sleeping better, thinking more clearly, and even feeling more thankful.

So I gave it a shot.

At first, it was strange. What was I supposed to say? Again with the grocery lists? What do I have to do? Angry rants? Thank you notes?

It might be all of the above, to be honest, because writing in a journal isn’t about making great essays. It’s about being truthful on paper.

And to be honest? It began to work. Let’s examine the research findings first, and then I’ll explain how and why.

The Science: Why Is Journaling Good for You?

Writing in a journal is not a new-age trend.

For decades, psychologists have been looking into it. It’s now an actual tool that therapists and counselors use. You’ll hear about two basic types:

Expressive writing involves writing honestly about your deepest ideas and feelings, typically over three to four sessions. It’s not about writing down what happened; it’s about figuring out what feelings were behind it.

Gratitude journaling involves writing down the positive aspects of your life. Writing down what you’re thankful for, from a massive event in your life to the barista who remembered your order.

Both are helpful.

WebMD even lists them: writing in a diary can help with anxiety, interrupt obsessive thinking cycles, make you more aware, control your emotions, and even make you healthier.

And here’s the best part: it doesn’t even have to be every day.

Writing in a journal occasionally has been shown to help people better understand their needs and feel more balanced.
