Background on Coffee and Tea

• Caffeine: widely used drug, found in coffee, tea, cola, cocoa beans, and kola nuts.
• Historical background: tea discovered in China around 1000 BC, coffee discovered in Ethiopia around 850 AD.
• Evolution of coffee consumption: from traditional brewing to modern-day coffee culture with far more caffeine in every cup of Joe.

Understanding Caffeine's Effects

• Mechanism of action: blocks adenosine receptors in the brain, resulting in increased alertness and focus.
• Varied responses to caffeine: genetic factors influence caffeine metabolism and sensitivity.

Potential Benefits of Caffeine

• Improved exercise performance: studies show 5-8% increase in power output.
• Reduced perception of pain and improved lung function in asthmatics.
• Potential benefits for cognitive health, stroke risk reduction, and liver disease, and temporarily reducing appetite.

Potential Downsides of Caffeine

• Short-term side effects: jitteriness, anxiety, increased heart rate, and urinary frequency.
• Impact on sleep: meta-analysis shows reduction in total sleep time and deep sleep.
• Temporary increase in blood pressure for some individuals. No long term increase in hypertension.
