Why Caffeine Might Be Hurting Your Productivity
Chris Bailey explains that while caffeine can boost focus, it also increases cortisol and adrenaline by up to 200%, which can trigger anxiety and reduce attentional capacity. This undermines productivity, especially for introverts or those already feeling anxious.
- Caffeine increases cortisol and adrenaline levels by about 200%, heightening stress.
- Anxiety from caffeine narrows attention, reducing mental capacity for focused work.
- L-theanine in green tea counteracts caffeine-related stress without sacrificing alertness.
- Introverts may be more sensitive to caffeine’s stimulating effects and should use it strategically.
“Caffeine increases cortisol levels about 200%. And adrenaline levels about 200%.”
“Anxiety puts a damper on productivity. It puts a damper on focus because it shrinks how much attention we have.”
