Why You Shouldn’t Drink Coffee First Thing in the Morning

Your Body Already Has a Wake-Up System

You might think that pouring a hot cup of coffee right after waking up is the best way to start your day. But here’s the twist: your body already has its own natural “alarm clock,” and that first cup of coffee might actually be working against it.

Meet Cortisol: Your Natural Energy Hormone

When you wake up, your body releases a hormone called cortisol. It helps you feel alert and energized, no caffeine needed. This spike usually happens within the first 30 to 60 minutes after waking.
But when you drink coffee during that peak cortisol window, your body may:

  • Become more dependent on caffeine over time
  • Produce less cortisol naturally
  • Experience a bigger energy crash later in the day

What Happens If You Wait?

By simply delaying your first cup of coffee by 60 to 90 minutes, you can:

  • Let cortisol do its job naturally
  • Keep your energy more stable
  • Get more benefit from your coffee when you do drink it
    Think of it like this: let your body wake up on its own first, then bring in the caffeine backup.

Bonus Tips for Morning Energy Without Coffee

If you need a little boost before that delayed cup:

  • Drink a full glass of water right after waking up
  • Get outside for a few minutes of sunlight
  • Do a few light stretches or a short walk
    These small steps signal to your brain that it’s time to start the day—and they do it naturally.

Takeaways

You don’t have to give up coffee—just time it better. By delaying your first cup by 60 to 90 minutes, you give your body a chance to wake up naturally. When you do sip that coffee later, it’ll actually work better for you! Try it and let your Care team know! ☕️
