The window of tolerance, a key concept in emotional regulation, is a framework for understanding a person’s capacity to deal with stress at a given moment. Consider when something stressful happens, and you say, “I can’t handle this right now.” That’s you outside your window of tolerance. Similarly, you have likely also had moments when you approached a complicated matter calmly and were able to resolve the problem effectively. Here is an example of you being within your window of tolerance. 

What Pushes Us Outside Our Window of Tolerance? 

The human brain is an incredible and complex organ. The Sympathetic Nervous System (SNS) is spread throughout our bodies and evolved during prehistoric times to react to acute and short-term life-threatening events like being chased by a predator or surviving a flash flood. It activates our fight, flight, freeze, and fawn responses when we experience stress, even today.

However, the bulk of stressors in modern lifestyles come from financial challenges, problems at work, social media,  family and social issues that are long-term in nature. Applying a system designed for short-term stress relief to prolonged circumstances leaves the SNS ill-equipped.

When our brain chemistry collides with ongoing stressful triggers, we struggle to understand and control our reactions. It can leave us irritable and anxious (hyperarousal) or fatigued (hypo-aroused). Sometimes, all we can do is freeze and go numb. These feelings indicate we are outside of our window of tolerance. If you already feel this way, another challenge can push you to the edge and into a collapsed or shut-down state emotionally.

Getting Back In The Window of Tolerance

Luckily, our incredible bodies come with excellent tools to help us regulate ourselves. 

Hyperarousal: 

Breathing: This sounds almost too simple, but slow and calm breathing is a powerful way to help your nervous system return to neutral. Try “box breathing” by breathing in for a count of 4, holding for 4, breathing out for 4, holding for 4, and repeating a few times. Adding simple arm movements or humming on the exhale can enhance the slowing down of your system.

Crying: Let it out! Tears are your body telling you it is holding too much inside. Crying releases feel-good chemicals that can ease pain and help us connect to positive feelings. 

Hypoarousal: 

Activity: Getting active can be difficult when we feel low. However, actively using the body can significantly enhance your sense of well-being. A brisk walk or a full-body stretch can re-energize you when lethargy takes over.

Human Connection: We are social creatures and most likely to thrive in mutual support systems. Sitting with people over a meal or enjoying a TV show together are simple ways to stay connected. Talk with people you trust, and be there to hear their struggles, too. Speaking to a therapist with the training, knowledge, and resources to advise you is also helpful.

Using the Window of Tolerance for Difficult Conversations

Challenging conversations can be hard to start, but they can also bring us closer to our loved ones. The best way to approach difficult conversations is to ensure the person is within their window of tolerance and will engage.

Suppose they are fidgety, distracted, unwell, yelling and slamming doors, or zoning out and non-responsive. In that case, they are outside their window of tolerance. However, a relaxed person who makes eye contact, has a pleasant demeanour, and a neutral tone of voice is most likely within their window of tolerance.

If you’re unsure about their tolerance capacity, try asking questions. For example:

• “I have something on my mind. Are you up for a chat?“
• “You’ve had a stressful day and need a little chill time. Can you come find me when you’re ready for a chat?“
• “Thank you for helping with dinner. Before I do the dishes, can we have some dessert and talk briefly?” 

Your capacity won’t always align with others. However, understanding the window of tolerance concept will allow you to effectively have challenging conversations and help foster the loving connections everyone needs. This knowledge empowers you to navigate your emotional responses and interactions with others.
