Knitting is cheap, easy to pick up, and increasingly recognized as a tool to fight harmful habits. From nail-biting and doomscrolling to helping people overcome addiction, the only side effect may be an abundance of scarves and hats.
Amanda Wilson, a finance worker from Mississauga, struggled with obsessive-compulsive disorder (OCD) for years. “I used to pick my skin until it scabbed and bite my nails until they were infected,” she says. Then she discovered knitting. “Since obsessively knitting, I now have beautiful nails and a healthy scalp,” Wilson explains.
Knitting as a Therapeutic Practice
Once considered a hobby for older adults, knitting is now respected as a legitimate mental health intervention. Personal stories and preliminary studies show it can improve emotional regulation and help replace destructive habits.
Carl Birmingham, a psychiatry professor at University of British Columbia, notes that while some may initially doubt its effectiveness for serious conditions like PTSD or eating disorders, the results can be remarkable. Knitting is affordable, portable, and its main side effect is making too many hats.
What the Science Says
Knitting has had a mixed reputation in scientific circles. Betsan Corkhill, a wellbeing coach and physiotherapist, says that once scientists hear the “k-word,” enthusiasm for research often fades. Similarly, Mia Hobbs, a clinical psychologist in London, notes that knitting’s historical association with women has limited serious study.
Most existing research relies on surveys of experienced knitters. For instance, a 2020 study found 90% of respondents said crochet made them calmer. But there are few controlled trials introducing knitting to non-knitters. Participants in residential treatment centers for eating disorders or addiction offer a better study environment, as they can dedicate time to learning the craft.
Emotional Regulation Through Repetition
Birmingham has studied knitting in young women with severe eating disorders. “Following strict protocols, including eating more, was very anxiety-provoking. Knitting helped reduce distress,” he says. About 75% reported less food-centered worry.
He explains that repetitive, two-handed knitting movements resemble EMDR (eye movement desensitization and reprocessing), a therapy for anxiety and PTSD. “Repetitive movements can activate the parasympathetic nervous system and calm the mind,” says Hobbs.
Knitting can even influence brain activity. Birmingham’s preliminary EEG studies suggest it may reduce activity in the insula and amygdala, areas tied to stress. And you don’t need to be an expert. “Even terrible knitters can benefit, as long as they engage both sides of the brain,” he adds.
Knitting to Replace Harmful Habits
Knitting also works as habit-replacement therapy. It keeps hands busy and provides a healthy outlet for negative emotions. “Knitting allows people to sit with feelings without being overwhelmed,” Hobbs explains.
One notable success story is Loes Veenstra from the Netherlands, who knitted over 550 jumpers to resist her cigarette addiction. Knitting can transform a simple craft into a powerful tool for personal growth.
