Caffeine Has a Half-Life

Insight

That 3 pm coffee is still a quarter-active at bedtime. Caffeine doesn't leave the body when the alertness wears off — it leaves hours later, often mid-sleep, quietly thinning the deepest stages of the night.

Why it works

Caffeine blocks the brain's sleep pressure signal rather than removing tiredness, so it postpones sleep while the debt keeps accumulating. The bill is paid in sleep quality, not just latency.

Practical takeaway

Set a caffeine curfew eight to ten hours before bedtime and hold it for one week. If bedtime is 10:30, the last coffee is lunchtime — test it honestly and compare the week.

Good question to ask someone

What would an 8 am-only caffeine week show you?
