Common Stressors
Stress and the stress response
How the body’s stress system works, why the let-down after stress can trigger attacks, and what helps.

Stress is the factor people with migraine most often name as a trigger 1. Understanding how the stress response works makes it much easier to manage.
The stress response is meant to protect you
When the brain senses a threat, it activates the HPA axis (hypothalamus, pituitary and adrenal glands) and the “fight or flight” nervous system. Stress hormones like cortisol and adrenaline rise to help you through the challenge. Ideally they then settle back down. Scientists call this “stability through change,” or allostasis 2.
When stress does not switch off
Hans Selye described three stages of the stress response: alarm, resistance and, if the stress continues long enough, exhaustion 2. Excessive, prolonged or poorly regulated stress responses lead to health problems over time. For a migraine brain, which already sits closer to its threshold, that ongoing load fills the bucket 3.
The “let-down” migraine
Many people get attacks not during a stressful period, but right after it: the first day of a vacation, or the weekend after a deadline. A sudden drop in stress hormones, along with changes in sleep and meal timing, is thought to play a role 1.
Stress and hormones are connected
The stress system and the reproductive hormone system are closely linked. Long-term stress can shift estrogen, progesterone and other hormones, which matters a great deal for migraine 4. This is one reason Dr. Harcourt evaluates stress and hormones together. See Hormones: testing and balance.
What helps
- Mindfulness and meditation have been shown in studies to reduce migraine frequency and medication use in some people 5,6.
- Behavioral therapies such as acceptance and commitment therapy can reduce disability 7.
- Regular routines for sleep, meals and exercise help buffer the let-down effect.
- Community and purpose: connection and meaning are part of resilience in Dr. Harcourt’s lifestyle model 2.
