Cortisol Is Already Doing The Job
In the early morning, your body produces high levels of cortisol—the hormone responsible for alertness.
Drinking coffee during this peak (usually within the first 30–60 minutes after waking) is like doubling up unnecessarily. Instead of boosting energy, it can confuse your system and lead to a crash later.
That “sleepy after coffee” feeling? Often caused by this mismatch.
You’re Dehydrated (And Coffee Makes It Worse)
After 6–8 hours of sleep, your body is naturally dehydrated. Coffee is a mild diuretic, which means it can increase fluid loss.
Dehydration leads to fatigue, brain fog, and low energy—exactly the opposite of what you want.
