There are so many joys a person can experience in life, but many of those same joys also come with stresses. For example, you may be happy to see your kids’ smiling faces when you pick them up from school (joy) but to get them, you have to rush and wait in a long line to pick them up (stresses).
Many people have a level of stress (arousal) that they can tolerate where it won’t interfere with their functioning. They can handle stresses, difficulties, noises/sounds, and more while still being mentally present, feeling all their emotions, and otherwise able to stay emotionally regulated.
One term for this is the “Window of Tolerance” – the amount of space someone has that allows for psychological comfort and flexibility. It’s not necessarily about happiness, but it is about being able to function despite what’s going on around them.
Those with mental health challenges, however, typically have a much smaller window of tolerance. Stresses and difficulties end up putting them above or below the window:
- Above the Window – This is called the “hyperarousal” zone. It is more common for people with anxiety. It is where their bodies react with excess energy, like nervousness and agitation, when the stresses do not fit into their window of tolerance.
- Below the Window – This is known as the “hypoarousal” zone. It is more common in those with depression. It is where a person’s response to issues not fitting in their window is to shut down, become numb, and give up.
Note: Admittedly, one of the limitations of the “Window of Tolerance” analogy is that it doesn’t explain why some people go “above the window” and some people go “below” other than an individual’s mental health. But the window of tolerance itself does help beneficially describe what a person can handle, and why it differs from one person to the next.
The Shrinking Window of Tolerance with Depression
When a person has depression, they have a smaller window of tolerance. That means that there are fewer things that they can handle before their window becomes full and overwhelmed. For example, a light criticism from a coworker becomes a head on collision, because their window is full and nothing else can fit through before it spills out below the window.
But why does this window shrink?
- Low Battery – Depression is exhausting, so a person with depression often has a low battery that is less capable of handling multiple tasks before being depleted.
- High Threat Systems – Those with both depression and anxiety have a higher than active threat detector, which misinterprets neutral or only mild threats as more significant threats.
- Minimal Backup – When your mental health is functioning, you have mechanisms in place to keep you “in your window.” Not so with chronic stress and depression, where the systems that usually calm us, like neurotransmitters, are not able to do their job.
The smaller the window, the less a person feels like they can handle. So our role as therapists is to try to get the window bigger.
How Do We Increase the Size of the Window of Tolerance?
Improving the size of the Window of Tolerance is something we do indirectly in therapy, by teaching coping tools and stress reduction mechanisms that allow us to stay grounded, present, and reduce negative critical thoughts.
