Drink coffee between 10–11 a.m. after breakfast, says Dr. Andrew Greenland. Timing lowers cortisol, steadies energy and protects sleep, Surrey readers learn.
Early‑Morning Cup May Spike Stress
Surrey coffee lovers may want to reset their routine after new advice from U.K. functional‑medicine physician Dr. Andrew Greenland, who warns that grabbing a latte within the first hour of waking can overstimulate the body’s natural cortisol cycle.
Science Behind the Timing
Cortisol—the “get‑up‑and‑go” hormone—peaks naturally when people first rise. Adding caffeine at that moment can provoke a second spike, leaving drinkers jittery by day’s end and restless at night, Greenland told industry site BeanSignal.
The 10 a.m. to 11 a.m. Sweet Spot
Research cited by the doctor shows that postponing coffee until 90–120 minutes after waking—roughly the mid‑morning window—provides alertness without disturbing sleep. For most workers, that translates to a cup between 10 a.m. and 11 a.m..
Why It Matters Locally
Canadians rank among the world’s heaviest coffee consumers; Statistics Canada reports that 72 percent of adults sip at least one cup daily. Surrey’s café boom makes the timing tweak especially relevant to commuters and remote workers who lean on early brews.
How to Sip Smarter
Greenland recommends eating first to blunt cortisol surges, limiting intake to one strong cup, and monitoring personal responses for headaches, energy dips or nighttime wake‑ups.
Hormones and Gender Factors
Women may feel extra benefits by cutting caffeine during the luteal phase of their menstrual cycle, when progesterone should dominate. Greenland says clients who adopt the mid‑morning rule often see calmer moods and fewer PMS symptoms.
Ongoing Individual Adjustment
The physician stresses that coffee’s impact is highly personal, shaped by stress levels, sleep quality and genetics. “Listen to your body,” he advises. “If a later cup leaves you clearer and calmer, that’s your proof.”
