\"\"Why energy matters more than time<\/strong><\/h4>

In many organizations, performance is still assessed through time: hours spent at the office, availability, and workload. This approach feels reassuring because it\u2019s easy to measure\u2014but it overlooks an essential factor: the quality of human energy. People living with attention deficit disorder with or without hyperactivity (ADHD) illustrate this particularly well. They often must mobilize more brain resources to start a task, sustain attention, and regulate emotions, which can translate into productivity peaks followed by periods of deep fatigue.<\/p>

Research on glucose metabolism shows that the brain consumes about 20% of the body\u2019s energy while representing only about 2% of its mass. Studies using PET imaging have also reported lower cerebral glucose metabolism in adults diagnosed with ADHD in key regions involved in attention and executive control (including higher\/superior prefrontal regions). This imbalance contributes to the sense of \u201cneurocognitive exhaustion\u201d described by many adults with ADHD.<\/p>

A particular neurocognitive dynamic<\/strong>.<\/p>

Imaging work suggests that reduced metabolic activity in prefrontal areas can impose a higher \u201cenergy cost\u201d to perform tasks that look routine from the outside. At the same time, all of us make countless decisions every day. Popular sources sometimes estimate this number in the tens of thousands; however, the exact figure varies widely by definition and measurement. What is better supported is the underlying concept: repeated decision-making can be associated with decision fatigue<\/em>\u2014a state where the quality of self-regulation and subsequent decisions can deteriorate, especially under sustained cognitive strain.<\/p>

For people with ADHD, this dynamic can become close to constant, even when decisions aren\u2019t particularly complex, because much of the day involves sustained executive control (staying on task, filtering distractions, shifting attention, inhibiting impulses). Work that requires persistent executive functioning is also associated with higher burnout risk among employees with ADHD, with executive function deficits proposed as a mediator. [8]<\/a> The invisible effort required to maintain attention, manage interactions, and \u201cmask\u201d difficulties often leads to exhaustion and a higher risk of burnout.\u00a0<\/strong><\/p>

Why measure energy rather than time?<\/strong><\/p>

Time-based culture no longer reflects reality. Productivity per hour does not necessarily increase with more hours worked, and cognitive fatigue shows up when we\u2019re asked to stay focused for too long. Two people can complete the same task with very different energy expenditure\u2014and that expenditure can vary for the same person from one day to the next.<\/p>

By focusing on mental, emotional, and physical energy, organizations can understand employees better and offer more appropriate accommodations: flexible hours, recovery periods, results-focused culture rather than presence-focused culture, and so on. Workplace flexibility and tailored adjustments are frequently highlighted as practical levers for neurodivergent inclusion (e.g., adapting schedules, reducing sensory distractions, enabling recovery). Recognizing energy variability also means not projecting one\u2019s own rhythm onto others.<\/p>

Fatigue and exhaustion: a vicious cycle<\/strong><\/p>

In adults with ADHD, brain hyperactivity can filter distractions less effectively and impose continuous vigilance. Every interaction or unexpected change may feel intense, and the accumulation of micro-decisions amplifies executive fatigue.<\/p>

Guilt about feeling exhausted adds another layer of stress. Some people develop sophisticated strategies to appear \u201clike everyone else\u201d (ultra-structured environments, constant reminders, choosing careers aligned with their strengths). These strategies can work for a time, but they have a cost: anxiety, depression, and energy collapse when a major event occurs or when workload suddenly increases. ADHD masking\/camouflaging is discussed in both clinical and lived-experience literature as potentially burdensome and exhausting over time.<\/p>

Organizing work around energy<\/strong><\/p>

Managing energy doesn\u2019t mean reducing workload\u2014it means organizing it differently. A first step is to observe personal rhythms: identify high- and low-energy periods and plan accordingly. Complex tasks (analysis, writing, strategic thinking) can be scheduled during energy peaks, while lower cognitive-load activities (filing, proofreading, emails) can be reserved for lower-energy moments.<\/p>

This approach often increases productivity while reducing exhaustion. Organizational support can include valuing results, encouraging calm environments, allowing regular breaks, and enabling schedule adjustments.<\/p>
