SHOW NOTES FOR EPISODE #4 Forms and Focus Discussion on Caffeine
- https://www.sciencedirect.com/ Caffeine is consumed by over 80% of U.S. adults.
- A randomization meta-analysis in up to 415,530 participants by Scientific Reports.
- Caffeine can readily cross the blood-brain barrier, and is believed to exert its neuro-cognitive effects by antagonizing adenosine receptors in the central nervous system.
- Despite the power to detect very small effects, our meta-analysis provided no evidence for causal long-term effects of habitual coffee consumption on global cognition or memory.
- Caffeine may exaggerate your responses to the stressful events of normal daily life.
- Caffeine notably reduces the time of slow-wave sleep, which is the restful stage of sleep that leaves us feeling refreshed and alert in the morning. Sleep deprivation the following day can cause fatigue and problems with learning, memory, problem-solving, and emotion regulation.
- BIG CONCLUSION: If caffeine affects your sleep, you will struggle to focus.
- If you are going to drink, don't drink past 10:00am
- Try a coffee alternative
- Drink less caffeine on days off to reduce tolerance
