Delay coffee 90-120 minutes after waking, and stop by late morning or 8-12 hours before bed. Morning-only coffee is the longevity-friendly pattern. Some people skip caffeine entirely to protect sleep.
Caffeine is worth using.

Drink coffee 90-120 minutes after waking, and stop early. Andrew Huberman, on his own show, recommends that delay so the natural cortisol pulse can clear adenosine, the sleep-pressure chemical, and he treats timing as mattering more than dose.
The strictest cutoff on the record is no caffeine after 11 AM. A study Matthew Walker described on Rangan Chatterjee's show found that one evening dose of caffeine cut deep sleep by 20%. Caffeine's half-life is 5-6 hours, so a 2 PM coffee is still 50% active at 8 PM, and the safe floor is never after early afternoon.
Morning-only coffee drinkers have younger epigenetic ages, and filtered brewing removes the diterpenes that raise cholesterol. Some people avoid caffeine entirely for emotional stability and sleep, and it appears on lists of substances to drop during a health reset.
