Abstract in brief

  • Over 80% of U.S. adults use caffeine, which enhances alertness, reaction time, and attention after low to moderate doses (40-300mg), while its impact on memory and decision-making is less clear.
  • Caffeine works by blocking adenosine receptors, promoting cognitive and physical performance, particularly at higher doses above 200mg.
  • For various demanding professions like military and transport workers, caffeine can help maintain necessary cognitive and physical abilities during periods of restricted sleep or fatigue.
