30 Seconds Summary7 New studies you MUST know about Caffeine
- Caffeine selectively enhances certain cognitive functions but may impair working memory and reaction times with chronic use.
- Long-term moderate caffeine consumption can lead to brain adaptations, potentially reducing working memory performance over time.
- Caffeine substantially impacts sleep, reducing sleep efficiency and quality; it should be consumed at least 8.8 hours before bedtime to avoid sleep disruption.
- The placebo effect of caffeine can significantly enhance performance in workouts, outweighing the actual benefits of caffeine itself.
- Caffeine shows no dose-response effect in physical performance; different doses (low to high) do not significantly alter outcomes in tasks like jumping performance.
- Regular caffeine consumers might not experience performance benefits from standard pre-workout caffeine doses due to habituation.
- Reducing or resetting caffeine intake can resensitize individuals to its effects, suggesting that periodic abstinence can restore responsiveness.
- Overall, caffeine's psychological or placebo effects are pronounced, and maintaining a low to moderate consumption might optimize its benefits while minimizing negatives like poor sleep and reduced cognitive performance.
