Understand your energy envelope.
Pacing means matching demand to what you can tolerate.
Higher demand – physical, cognitive, or emotional exertion
Delayed worsening – a pattern that can occur with PEM
More manageable range – observed over time, not a guaranteed safe zone
Elara in everyday life
Less logging.
More context.
Energy & pacing
See energy and exertion together.
Review entries against your own history instead of a generic activity target.
Trends
See patterns across more than one day.
Switch between 14, 30, 90 and 300 days to put individual entries in context.
Activity & recovery
Document activity and rest together.
Keep physical, cognitive and everyday exertion beside recovery periods.
Sleep
Put sleep into the wider picture.
Review duration and interruptions beside how you felt afterwards.
Visibility changes things.
Wearables already measure heart rate, sleep and exertion. But they are built for sport, not for illness — they reward doing more, where what counts is doing less.
Your measurements beside your entries.
