Caffeine Cutoff Calculator

Caffeine leaves the body gradually rather than all at once. This tool estimates how much of what you drink today may still be active at bedtime, and suggests a window for finishing your last caffeinated drink. It is a planning estimate, not medical advice, and it cannot tell you how you personally respond.

The Science of Sleep

It’s not just about
hours in bed.

A night is not one long block of rest. Your brain moves through repeating cycles, and the mix of stages shifts as the night goes on — which is why when you sleep can matter as much as how long.

Deep sleep — physical repair

Concentrated in the first few cycles of the night. Growth hormone release peaks here, and it is the stage most associated with feeling physically restored. Roughly 13–23% of a healthy adult’s night.

REM sleep — memory and mood

Periods get longer towards morning, so the last hours of the night hold most of it. Associated with memory consolidation and emotional processing. Roughly 20–25% of a healthy adult’s night — which is why cutting sleep short trims REM first.

Sleeping a full night and still waking unrefreshed has many possible causes, including breathing problems during sleep. If that is a regular experience for you, it is worth discussing with a doctor rather than treating it as a habit to fix.

The Ideal Bedroom Setup: A Room Audit You Can Do Tonight

The ideal bedroom setup is mostly subtraction, not shopping. Walk your own room in the order a night happens - what it is for, what you can see, hear, feel and breathe - and fix the loudest problem first.
