Coffee: Brain Booster or Sleep Stealer?
25 Mar
Summary
- Dr. Faye Begeti limits caffeine intake to before 1:15 PM daily.
- Caffeine can reduce sleep efficiency and deep sleep by seven percent.
- Coffee may offer neuroprotective benefits and improve brain function.
Dr. Faye Begeti, a neurology doctor and neuroscientist, emphasizes the critical need to balance caffeine's cognitive advantages with its impact on sleep. She adheres to a strict personal policy of consuming caffeine only before 1:15 PM daily.
Dr. Begeti explains that even if one can fall asleep after drinking coffee, it often indicates underlying sleep deprivation. Caffeine consumption can decrease sleep efficiency by seven percent, particularly affecting deep sleep, which is crucial for removing misfolded proteins.
She notes that reliance on caffeine can develop, advocating for selective use and opting for decaf beverages when the neuroprotective benefits of caffeine are not specifically needed. This approach helps maintain a "fine balance" between enhancing brain function and safeguarding restful sleep.
