A study from the University of Kentucky depicted that more than 78% of college freshmen consume above the recommended amount of caffeine each day.[13] In a study from the Henry Ford Hospital's Sleep and Research Center and Wayne State College of Medicine, they discovered that caffeine consumed within six hours of bedtime can significantly disrupt sleep.[14] Participants in this study who consumed caffeine right before bedtime, three hours before bedtime, and six hours before bedtime all experienced a shorter night's sleep, lower sleep quality, and spent more time awake at night.[14]
