How to respond to state changes

Have you ever noticed how some days you feel calm and productive, while other days you feel overwhelmed or exhausted? This fluctuation in our ability to engage with life is closely linked to our Window of Tolerance which is a concept from neuroscience and trauma research that describes the optimal zone where we can think clearly, regulate our emotions, and respond to stress in a balanced way. But what many people don’t realise is that this window is also deeply connected to our energy levels.

​Understanding the Window of Tolerance coined by Dr. Dan Siegel, the Window of Tolerance refers to the range of arousal states where our nervous system functions optimally. Within this window, we feel alert yet calm, present, and engaged. When we move outside of this window due to stress, fatigue, or other challenges, we can shift into:

• Hyperarousal: A state of heightened activation, often experienced as anxiety, panic, irritability, or restlessness.
• Hypoarousal: A state of low activation, which can feel like exhaustion, numbness, disconnection, or depression.

Moving between these states is normal, so next time you notice a state change, perhaps you can try the following techniques?

Here are three strategies to support the return from hyperarousal to a state of safety:

1. Grounding Techniques – Engage the senses to bring awareness back to the present moment. Try the 5-4-3-2-1 technique: Identify five things you see, four things you feel, three things you hear, two things you smell, and one thing you taste. This helps shift focus away from distressing thoughts and physiological arousal.
2. Physiological Sighing – This involves taking a double inhale through the nose, followed by a slow exhale through the mouth. Research shows that this breathing pattern effectively reduces sympathetic nervous system activation, promoting relaxation and vagal tone.
3. Progressive Muscle Relaxation (PMR) – Systematically tense and release muscle groups, starting from the feet and moving upward. This not only reduces muscle tension but also signals to the nervous system that the threat response can deactivate.

​Here are three strategies to support the return from hypoarousal to a state of calm and engagement:

1. Rhythmic Movement & Activation – Engage in gentle, rhythmic movement such as rocking, stretching, or walking. Bilateral stimulation, like tapping alternating sides of the body or slow-paced dancing, can help increase energy and reconnect with the body.
2. Breathwork for Energy – Use activating breath patterns such as paced breathing (e.g., inhale for 4, exhale for 2) or short, sharp inhales followed by a longer exhale. These techniques help stimulate the autonomic nervous system and bring in more alertness.
3. Engaging the Senses – Use cold stimulation (e.g., splashing cold water on the face, holding an ice cube) or strong sensory input (e.g., citrus scents, upbeat music, textured objects) to gently awaken the nervous system and bring awareness back to the present.

Your energy levels and nervous system regulation go hand in hand. By paying attention to what expands or shrinks your Window of Tolerance, you can cultivate greater resilience and ease in your daily life. This awareness allows you to move through life with more balance, adaptability, and well-being.
