Sleep
Morning Caffeine Only Rule
A morning caffeine only rule limits intake before a set clock—often ten a.m. or noon—protecting sleep while tapering total daily milligrams.
A morning caffeine only rule stops coffee, tea, and energy drinks after a set clock—often ten a. m.
or noon—so adenosine pressure can build before bed. It is a middle step in taper plans, not always the final goal.
Half-life varies by genetics; sensitive sleepers may need earlier cutoffs. Pair with bright morning light to replace afternoon stimulation.
Common questions
-
Is noon caffeine safe for sleep?
For many slow metabolizers, noon coffee still disrupts deep sleep. If latency stays high, move cutoff to ten a.m. or reduce milligrams instead of only shifting time.
