Sleep & Recovery
Your New Caffeine Cutoff
Caffeine has a 5–6 hour half-life. That 3 PM latte is still in you at 9 PM.
The quick explanation
In midlife, caffeine sensitivity often increases. A noon cutoff dramatically improves sleep depth without sacrificing morning lift.
Why this matters
Better sleep raises tomorrow's energy more than any afternoon coffee can.
