In a protocol
Moderate coffee intake (1–4 cups/day), consumed mostly in the first half of the day, appears to support long-term health including cardiovascular and cognitive outcomes.
“three to four cups of coffee a day was associated with a 19% lower risk

In a protocol
Avoid caffeine within 8–10 hours of bedtime; even six hours before bed can significantly disrupt sleep.
“caffeine consumed a full six hours before bedtime objectively disrupted sleep

In a protocol
Avoid clustering large doses of caffeine (3–5 cups equivalent) in the afternoon or evening.
“three, four, five cups... clustered into a narrow window
TM▶ 21:30DosageAvoid >3 cups equivalent late in dayCertaintyexplicitstrong warningAvoid clustering high doses late in the day -
In a protocol Alternative
For afternoon/evening coffee ritual, swap to decaf to retain antioxidant benefits without caffeine's sleep disruption.
“if you love the ritual of an afternoon or evening cup, consider decaf

In a protocol
Run a two-week self-experiment: fix wake time, set caffeine curfew 8–10 hours before bed, keep coffee moderate and early, and track sleep onset, awakenings, and morning feel.
“For two weeks, fix your wake-up time. Set a caffeine sunset
