Raising awareness of the effect of emotional stress on autoimmune disease
More than 20 years of research link chronic emotional stress with the onset and flare-ups of autoimmune disease. Project I exists so that patients, families and health practitioners recognize that connection — and treat stress as part of health, not separate from it.
Why this project matters
Autoimmune conditions — such as rheumatoid arthritis, lupus, multiple sclerosis, type 1 diabetes, Crohn’s and colitis, psoriasis and many others — affect millions of Canadians. While genetics play a role, research increasingly shows that prolonged emotional stress is a significant factor in whether those genes are expressed, in how severe symptoms become, and in how often the disease flares.
And yet stress is rarely part of the conversation at diagnosis. Patients are handed prescriptions and pamphlets, while the emotional weight of their lives — grief, overwork, caregiving, financial pressure, isolation — goes unexamined and untreated.
What we do
- Share the science in plain language — summarizing peer-reviewed findings on the stress–autoimmune connection so people can actually use them.
- Publish resources — reading lists, self-assessment guides and practitioner questions on our Read page.
- Support patients and caregivers — connecting people with programs, practitioners and community resources that address the emotional side of chronic illness.
- Fund awareness work — directing donations toward education that makes the emotional-health connection visible.
The connection in brief
Chronic stress keeps the body’s threat response switched on. Cortisol and other stress hormones, meant for short bursts, stay elevated for months or years. The immune system is gradually dysregulated — inflammation rises, immune tolerance weakens, and in people with susceptibility, the body can begin attacking its own tissue. Research has documented:
- significantly elevated risk of autoimmune disease following major stress disorders and trauma;
- stressful life events preceding the onset and worsening of rheumatoid arthritis, psoriasis, inflammatory bowel disease and other conditions;
- higher flare rates during periods of grief, depression and chronic strain.
None of this means autoimmune disease is “in someone’s head.” It means emotional health and physical health are inseparable — and treating both produces better outcomes.
Recognize the signs
If you or someone close to you has an autoimmune condition, ask:
- Did symptoms begin or worsen after a period of significant stress or loss?
- Is stress being managed — or simply endured?
- Do care plans address sleep, emotional support and mental health — or only the physical symptoms?
If those questions raise concerns, bring them to your physician, and explore the resources on our Read page.
