Train Your Nervous System for Sleep, Stress, and Focus

Executives can leave the office and still feel mentally stuck at work. An elevated heart rate at bedtime, fragmented sleep, and difficulty being present with family may persist even after setting boundaries. This article argues that the obstacle is not simply discipline or time management, but an autonomic nervous system that has trouble shifting out of high-alert mode. The proposed approach is to build the ability to move between activation and recovery. Rather than giving up career ambitions or relying only on calendar changes, leaders can learn to notice their stress responses and practice ways to downshift. How past stress can shape executive reactions Chronic work stress may connect with earlier experiences, including unprocessed stress, childhood feelings of not being good enough, or past trauma. The article describes the vagus nerve as part of the body’s threat-detection and recovery systems. When the nervous system stays hypervigilant, a routine deadline, difficult board feedback, or a sudden strategy change can prompt a fight, flight, or freeze response instead of a measured reaction. In this account, recognizing those patterns is an important step toward changing them. A strong reaction to a present-day business challenge may reflect more than the immediate situation; past stress can influence how threatening it feels. Why relaxing can be difficult The sympathetic nervous system is likened to an accelerator. During demanding work, it helps keep a person alert, with cortisol and adrenaline supporting action. But if the body remains in this activated state after the pressure passes, it may be hard to transition into rest. The result can be irritability, emotional exhaustion, and difficulty focusing on life outside work. Dr. Jo Brown, Head of Performance at Nuropod and a human performance engineer who consults with elite performers, compared the sympathetic nervous system to a car’s accelerator and the parasympathetic system to its brake. In the interview linked below, she said high performance depends not only on accelerating but also on being able to brake when conditions change. She described “autonomic flexibility” as the capacity to move between these nervous-system states as needed. Listen to the interview with Dr. Jo Brown. The vagus nerve, which originates in the brain as the tenth cranial nerve, is described as a primary pathway for parasympathetic recovery. The article also refers to Dr. Stephen Porges’ Polyvagal Theory, which connects the vagus nerve with the “Social Engagement System,” a state associated with safety, connection, and the ability to think strategically. Three pillars for training the nervous system Dr. Brown’s framework is “Regulate, Recover, and Rewire.” It treats nervous-system skills as something to practice, alongside physical strength, mental skills, and professional expertise. 1. Regulate: use brief resets The first pillar focuses on creating a deliberate transition out of work mode. The article describes non-invasive transcutaneous vagus nerve stimulation (tVNS) wearables, including Neuropod, as a way to provide gentle electrical micro-currents to superficial nerve fibers at the ear, specifically the tragus. It suggests using these devices for 5 to 15 minutes at the end of the workday to signal that work-related demands have ended and support a transition into family time. 2. Recover: support sleep and track stress Recovery habits such as keeping a consistent sleep schedule, exercising, and eating well matter, but the article notes that Heart Rate Variability (HRV) cannot be raised on demand through willpower alone. HRV is governed by the vagus nerve and autonomic nervous system. Bio-wearables can track HRV and offer information about internal stress; a drop may indicate that the body has not recovered fully. Low HRV can correlate with feeling anxious, down, or emotionally drained, sometimes before a person recognizes burnout. The article also connects lingering stress with waking between 2:00 AM and 3:00 AM and being unable to quiet racing thoughts. It cites research on how athletes handle pressure and the nervous system, and says clinical research shows targeted ear-based vagus nerve stimulation can lower nighttime heart rate, improve HRV, and restore deep slow-wave sleep. 3. Rewire: preserve strategic focus The final pillar is the longer-term goal: learning to downshift more effectively so the prefrontal cortex remains accessible. The article links this capacity with clearer strategic thinking during the day and deeper engagement at night, rather than remaining in constant survival mode. What to take forward Finding balance does not have to mean quitting a demanding career or lowering expectations. The next step is to understand how your nervous system responds, notice when it is activated, and identify what helps you return to a more settled state. For executives who struggle to switch off after work, this framework offers a way to think about boundaries as both practical choices and physiological transitions.
