Coffee, Yay or Nay? Here’s What Caffeine really Does to Your Heart and Brain

Caffeine has shown to influence cognition and mood. Its effects, however, vary depending on the amount of and time of consumption.

Individuals who are habitual consumers of coffee and tea have been shown to perform better on various tests of cognitive performance such as reaction time and visual-spatial skills.
