Caffeine and your evening: why timing matters

Caffeine is a stimulant with a long reach. It blocks adenosine, the molecule that builds up through the day and tells your brain it is time to wind down, and it has a half-life of around five to six hours.

That means a regular cup in the late afternoon can still be quietly at work well into the evening, nudging your sleep later and lighter without you noticing the connection.

Swapping to a naturally caffeine-free cup in the evening removes that hidden obstacle. Quiet Hours leans on chamomile, lemon balm and mellow mint, herbs with a long tradition of use for calm, so the ritual can do its job without the stimulant pulling the other way.

You do not have to give up the warm-cup habit at night. You just give it a blend that is on your side.
