What is your Window of Tolerance?


Introduce yourself: Jan and Sarah are two entrepreneurs with a successful business. They both work on a high-pressure project that requires them to knock long hours and make tough decisions. One day they receive negative feedback from an important client that threatens to derail the project.

Jan's tolerance limit is exceeded. He becomes overwhelmed and feels like everything is falling apart. He becomes irritable and critical of the team, and begins to obsess over every detail of the project. He feels paralyzed by the situation and begins to doubt his decisions, which only makes the situation worse.

Sarah's tolerance threshold, on the other hand, is not broken. She acknowledges the customer's negative feedback, but does not let it derail her efforts. Instead, she takes a step back to assess the situation and draw out an action plan. She consults with her team to discuss the feedback and brainstorm answers for the customer's concerns. She also contacts her focus group for guidance and support. By staying within her Window of Tolerance, Sarah is able to approach the situation calmly and thoughtfully and ultimately save the project.

The Window of Tolerance.

The Window of Tolerance is a term from psychology that refers to the range of emotional and physiological arousal within which a person can function effectively. The term was first used by Dan Siegel, a psychiatrist and neurobiologist, to describe the optimal state of arousal for learning and growth.

When a person's level of arousal is within their tolerance limits, they can respond flexibly and adaptively to challenges. Then you can regulate your emotions and behavior, make decisions and solve problems effectively. When a person's level of arousal exceeds his tolerance limits, he can become overwhelmed by stress, anxiety or other emotions. This can lead to behaviors such as avoidance, dissociation or aggression.

The size of a person's tolerance limit is influenced by a combination of factors such as genetics, past experiences and current environmental stressors. It can also vary over time, depending on a person's emotional and physical state.

Therapists often use the concept of the tolerance boundary to help clients understand their own emotional state and develop strategies to regulate their emotions. This may involve identifying triggers that push them out of their Window of Tolerance, and developing coping mechanisms to bring them back into it.

This example illustrates how important it is to stay within your own tolerance limit in stressful situations. That way, you can regulate your emotions, think clearly and make more effective decisions. In contrast, when the tolerance limit is exceeded, you are more likely to become overwhelmed and reactive and make impulsive decisions that can be counterproductive.

How do you recognize that your tolerance limit is exceeded?


Recognizing when your tolerance limit has been crossed can be challenging, but there are some common signs and symptoms you can watch for. Some examples:

Physical sensations: When your tolerance limit is exceeded, you may experience physical sensations such as increased heart rate, shallow breathing, sweating, tension in your muscles, or sometimes even a feeling of nausea.

Emotional changes: noticing changes in your emotions, such as feeling overwhelmed, anxious, angry or irritable. Some just become numb or feel disconnected from their emotions.

Cognitive changes: some experience difficulty concentrating, have difficulty organizing their thoughts, or experience a sense of confusion or disorientation.

Behavioral changes, such as withdrawing from others, avoiding situations that trigger our stress response, arguing or becoming aggressive.

Interpersonal changes: You may notice changes in your relationships, such as feeling more distant or disconnected from others, or becoming more reactive or defensive in your interactions.

It is crucial to pay attention to these signs and symptoms and take steps to regulate your emotions and return to your "Window of Tolerance. This may mean taking a break from a stressful situation, practicing relaxation techniques, seeking social support or taking other actions that will help you feel more balanced and grounded. Here are more concrete tips.

What misconceptions exist about the Window of Tolerance?

There are several misconceptions about our Window of Tolerance that are important to address.

The tolerance window is a "fixed trait": A common misconception is that a person's tolerance limit is fixed and cannot be changed. In reality, a person's tolerance limit can increase or decrease over time in response to factors such as stress, trauma and personal growth.

The tolerance boundary is the same for everyone: Although there are general principles governing the tolerance boundary, the size and shape of the boundary can vary greatly between individuals based on factors such as genetics, early childhood experiences and current life circumstances.

Staying within the tolerance limit means always feeling happy: Another common misconception is that being within the tolerance line means always feeling calm and happy. In reality, falling within the tolerance line means having a range of emotional experiences, but being able to regulate those emotions in a healthy way.

The tolerance window is a static state: The tolerance window is not a static state, but rather a dynamic range of emotional and physiological arousal. A person can enter and exit his tolerance threshold throughout the day, depending on his experiences and environment.

It is important to recognize that our tolerance range is a complex and multifaceted concept influenced by a range of factors. By understanding these misconceptions, we can better understand how to improve our ability to manage stress and regulate our emotions.

What can you do to increase your Window of Tolerance?

There are several strategies you can use to increase your tolerance, and thus strengthen your ability to cope with stress, and better regulate your emotions. Here are a few:

1. Practice some form of mindfulness. Regular practice of mindfulness, such as meditation, can help you become more aware of your thoughts and emotions, and better able to regulate them. You recognize when a situation is approaching your tolerance limit, and can take proactive action(s) to redirect it.  

2. Get regular exercise: Physical activity can help reduce stress and improve your ability to manage your emotions. Even a short walk or other light physical activity can be beneficial.

3. Develop healthy sleep habits: adequate restful sleep improves our ability to manage stress and regulate our emotions. Try to establish a regular sleep schedule and create a relaxing routine before bedtime. Our interview with Aisha Cortoos elaborates on this.

4. Activate your social circle: Having a support network of friends, family, or a therapist can help eliminate loneliness, have a sounding board, and put certain situations into perspective.

5. Practice relaxation techniques: techniques such as deep breathing, progressive muscle relaxation or yoga help regulate your emotions and reduce stress. A body under stress experiences a smaller Window of Tolerance anyway.

6. Identify and challenge limiting or negative thought patterns: such thought patterns contribute to stress and anxiety. Hold a mirror up to some persistent beliefs, and dare to question whether or not they are serving you at this time. It is best not to do this exercise alone.

7. Any exercise that takes your self-awareness to a higher level will allow you to recognize your tolerance limits, and thus deal with them proactively and consciously. Regularly reflecting on the situations where you felt your boundaries were crossed will give you tools to better navigate such situations in the future.  

Remember that increasing our tolerance is a process that takes time and practice. Be patient and dare to ask for help. Good luck!
