Might I introduce you to the wonder of reusable cable ties?

They have a release tab. You can undo them, adjust the cables, then retighten them.

Circadian rhythm maintenance.

Melatonin is broken down in the eye by blueish light. When this stops, the melatonin levels begin to climb, leading to tiredness.

This is also why phones etc keep you awake.
