The question
Modern work can make availability feel like a default state: messages at breakfast, meetings all day, decisions late at night.
02 · What happens inside
What happens inside
The nervous system continuously responds to cues and demands. Repeated interruption can keep attention oriented toward external signals, while late activity and light exposure can also interact with sleep timing.
03 · What science tells us
What science tells us
Sleep and circadian research shows that light, timing and sleep opportunity influence biological rhythms and daytime function. The evidence is stronger for specific exposures than for broad claims that modern technology has 'damaged' human biology.
04 · What remains uncertain
What remains uncertain
Being connected is not automatically harmful. The relevant variables include timing, duration, intensity, controllability and what digital activity replaces.
05 · ÉQUILO perspective
ÉQUILO perspective
The problem may not be that humans are always on. It may be that we have become less deliberate about when we are supposed to be off.
06 · One thing to take away
One thing to take away
A system that receives signals all day still needs periods in which those signals stop competing for priority.
