Gratitude

Taking time every day to think about what you’re thankful for isn’t merely the “right” thing to do, it also helps you feel more relaxed and content, because it reduces the stress hormone cortisol by over 20%. 
 Research conducted at the University of California, Davis found that people who worked daily to openly

express their appreciation and gratitude experienced improved moods, energy levels, and physical health, even during bouts of stress.  It’s highly likely that their lower cortisol levels played a major role in this.
