Why mornings win on Instagram
Three behavioural drivers:
Pre-deep-work scroll. Office and remote workers settle in but haven't entered focused work yet.
Meeting transitions. 10-15 minute gaps between morning meetings = scroll-filled.
Lower competition. Many accounts default to evening posts. Mornings are less saturated.
