Drinking coffee right after waking backfires because cortisol is already peaking. Wait 60 to 90 minutes instead, and you'll avoid the afternoon energy crash that comes from spiking stress hormones too early.
Most people think that their first cup of caffeine should be the second that they wake up, but that's actually the worst time to drink it, and here's why. When you wake up, your cortisol, your natural energy hormone, is already at its highest. So if you slam caffeine right away, you spike stress hormones and you will crash faster later. So the smarter move would be to wait 60 to 90 minutes after waking up for your first tea or coffee, and this way you'll get better energy without the afternoon crash.
