Every night before he sleeps, filmmaker and musician Bruce Sheridan writes one page in a lined Moleskin notebook with a black cover.

He uses his journals as an aid to memory and creativity. He can go back into things written years earlier to encounter ideas for songs and other creative work, and finds that his Columbia College students who keep journals do better than those who don’t.

“Almost all creativity, if you really dig into it, is novel ways of using what already exists, what you already know,” said Sheridan, who researches creativity. “I think the journal has a huge role to play in that.”

Keeping a journal is often thought of as something that begins and ends in adolescence. But artists who keep journals and psychologists who recommend it to patients say that it can be a way of relieving stress, moving past trauma, firing creativity and giving life meaning.

“Journaling gives people perspective,” said psychologist Howard Weissman, who founded the Chicago Stress Relief Center. “It does that by tapping into the unconscious. Once you put a pen between your fingers or your fingertips touch the keyboard, it opens up this free associative process of the unconscious, which opens the door to creativity.”

Journals can help people cope by giving them a “satellite view” of their problems, instead of seeing them at a microscopic level, Weissman said.

“When you write about the details of the stresses and challenges of your life, you shrink the problem in order to expand your perspective,” he said.

During tumultuous historic or personal times when things can seem out of control, keeping a journal can be a way to strengthen one’s inner voice, allowing a “pregnant pause,” Weissman said. “It provides a quiet time to reflect, and that reflection creates an opportunity to create time and quiet and this meaningful solitude which is so important during times of chaos,” he said.

Lisa Page, a clinical psychologist in Park Ridge, Ill., said she encourages everyone to keep a journal, citing research that it could help strengthen the immune system. She uses it in her practice to help relieve stress and insomnia.

Page believes this works because writing in a journal can slow down the mind and stop racing thoughts.

“It doesn’t have to be pretty,” said Page. “It doesn’t have to be complete sentences. Just try writing for five minutes. People come back and tell me, ‘Oh my gosh, it was so cathartic. I went on to write for 20 or 30 minutes.’”

Aimee Daramus, a psychologist at Behavioral Health Associates in Chicago, said writing in a journal can help people describe their own experiences, creating a feeling of control.

“Sometimes your mind will get so complicated, so full, that even you don’t know what’s happening to you,” Daramus said.

Journals have been disparaged as self-absorbed. But Kenneth Fils, a psychologist who runs a large group practice in nursing homes, said writing can help with empathy. By learning to listen to yourself, you can listen better to others, he said.

“You have more of an ability to step back and listen in a different way,” said Fils, who has taught journaling.

Sheridan has kept journals on and off since childhood, but started a daily practice a few years after his mother was diagnosed with Alzheimer’s disease, perhaps in part because he feared forgetting things. Then he started to see it as an “aesthetic discipline.”

Both Sheridan and mental health professionals interviewed recommend keeping a handwritten journal, rather than one on a computer, if possible.

“It uses a different brain process, and it’s much more cathartic than typing on a computer,” said Page. New research shows that students who write their notes by hand, rather than typing them, learn more.

Weissman also sees writing in a journal as different from posting on Facebook or Twitter, because social media is not designed for authenticity and vulnerability.

“In journal writing, people have an opportunity to face their vulnerability and whatever imperfections that they may be struggling with, and be real with that,” said Weissman.

There can be pitfalls, and keeping a journal doesn’t work for everybody. Daramus said the practice can go wrong when it acts as a way to “stay stuck” in a situation instead of as a tool to move on.

Sheridan, too, said he sees a hazard in spending too much time writing in a journal rather than acting on some of the ideas you write about.

But Sheridan said keeping a journal helps him pay attention, weaves the different parts of his life together and makes him feel they are all related and connected.

Weissman thinks some people give up keeping a journal as teens, because they get lost in the details of their lives. Days blur into decades before some people pause and reflect how they got where they are.

“Journaling is a way of slowing down our limited lease on life and appreciating with gratitude that which makes life meaningful and joyful and worthwhile,” Weissman said.
