A thank-you note is having a moment, and psychologists say the habit can do more than tidy up your thoughts.

Gratitude correspondence is a wellness trend focused on positive thoughts, slowing down, and being grateful for the people around you. It involves consciously sending a letter or note to someone in your life as a meaningful thank you, usually focused on how that person has affected your life in a positive way.

Like gratitude journaling, the practice centres on positivity.

“When you practice gratitude regularly, you are literally retraining your brain,” said Michelle Drapkin, a board-certified psychologist and Founder and Director of The CBT Center in New Jersey.

“Our minds are wired to scan for threats, problems, things that are wrong,” she said.

“Gratitude practice interrupts that pattern and teaches your brain to scan for what’s good instead.”

Drapkin said consistency matters because, when you do it regularly, “that shift becomes more automatic.”

She said gratitude letters should be specific.

“Vague gratitude is easy to dismiss,” she said.

Drapkin said focusing on one moment and “telling the story of it like you’re painting a picture” is how to effectively retrain your brain to focus on the positives.

“That level of detail is what activates the brain.”

She said the benefits are not limited to the person writing the note.

“We often think about the people who matter to us and never say it out loud,” Drapkin said.

“Writing to someone gives those thoughts somewhere to go. It builds connection, communicates that someone is seen and appreciated, and engages that same brain-retraining in a social context.”

“When done with intention, it works,” she said. “You retrain your brain, you strengthen a relationship, and someone in your life feels seen. Win, win, win.”
