An executive does the work with a body that needs sleep, movement, nourishment and appropriate health care. Those needs can be overlooked when performance is judged only by visible output.
Recognizing them does not mean that physiology explains every leadership difficulty.
Examine the role's actual demands
Look at the combined effects of travel, late work, preparation and constant availability. A series of individually reasonable requests may leave little room for ordinary recovery.
Ask which demands the organization can change. Clearer authority, better preparation and a realistic escalation rule can reduce pressure without relying entirely on the executive to cope differently.

Use measurements within their limits
A wearable may help describe a personal trend. It does not directly measure commercial judgment, diagnose burnout or establish why a decision went wrong.
Persistent changes in health or functioning deserve qualified assessment. Advisory work can examine the job, while clinical questions need appropriate expertise.
For a business intervention, choose an observable outcome: fewer delayed decisions, a manageable travel pattern or work that usually stops at the intended time.
A responsible approach can take the body seriously while keeping claims proportionate. The executive should be able to understand what is being measured, what remains an interpretation and what action the evidence supports.
