Executive Health Drift is the gradual decline in how a leader feels and functions that slowly becomes normal. Energy, sleep, focus, patience and fitness slip a little at a time, usually over years, while the business keeps performing. Because the change is slow, most leaders don't notice it. They simply adjust to feeling worse.
We use the term at TRUTH because the leaders we work with rarely describe a crisis. They describe something quieter. "I'm fine, just tired." "I used to have more in the tank." "I can't remember the last time I felt properly sharp."
Executive Health Drift isn't a medical diagnosis, and it isn't the same as burnout or illness. It's a pattern. Small compromises made for good reasons (a late night to finish the deck, a skipped session because the diary moved, another coffee to get through the afternoon) add up. Over months and years, they change your baseline.
The important word is normal. Drift is hard to spot precisely because you stop comparing how you feel today with how you felt five or ten years ago. You compare today with yesterday, and yesterday looked much the same.
Most leaders recognise a few of these rather than all of them:
On their own, none of these is unusual. Together, and persisting, they're a sign your baseline has moved.
Drift tends to affect the people who are best at pushing through. The habits that build a business (taking responsibility, putting others first, working through discomfort) are the same habits that push your own health down the list.
A few patterns come up again and again:
You can read one founder's story of this in Steve's story: twenty years of building a business.
Burnout is usually described as a state of exhaustion that comes from long-term work stress that hasn't been managed. Executive Health Drift is often what comes before it, or what happens instead: a slower loss of capacity where you keep functioning, keep delivering and keep going, but with less in reserve each year.
That difference matters. Drift is something you can act on early, while you still have the energy to make changes. If you feel persistently low, anxious or unable to cope, speak to your GP. That's the right first step, and it's a sign of good judgement, not weakness.
The biggest challenge isn't fixing drift. It's noticing it. A few practical starting points:
Drift rarely affects just one person. When a whole senior team is running on less, it shows up in slower decisions, shorter tempers and less appetite for the bigger thinking the business depends on. Our Executive Health Drift briefing helps boards and leadership teams recognise the pattern together and agree practical next steps.
No. It's a way of describing a common pattern in leaders: a gradual decline in energy, sleep, focus and fitness that becomes normal over time. If you're worried about your health, speak to your GP.
Compare how you feel now with how you felt a few years ago, not with last week. If several of the signs above have crept in and stayed, it's worth taking stock.
In our experience, most leaders can feel and function much better once they rebuild sleep, recovery, movement and habits around the life they actually lead. Progress is usually steady rather than dramatic.
Executive Health Drift is a term developed by Cameron Harris, founder of TRUTH Executive Health, to describe the pattern he has seen in founders, CEOs and senior leaders over two decades of coaching.
