Caffeinated Drinks

Think twice before downing a latte or diet Coke. According to a study from the University of Bristol, caffeinated drinks may increase your stress levels, rather than helping to keep them under control. In a trial of 96 people, researchers found that individuals with caffeine in their system had higher heart rates, performed less effectively as part of a team, and felt more “stressed out” than individuals who went caffeine-free.
