We’re all likely familiar with the idea that love is energizing; for example, Joe Cocker and Jennifer Warnes encapsulated this notion in their 1982 single Up Where We Belong when they sang, “Love lifts us up where we belong....” But does love really physically energize us? It’s definitely possible. Love is associated with positive emotions and simply thinking about love can trigger stress responses (such as increases in cortisol) in the body, responses thought to result from arousal or passion. One intriguing thing that can happen when your body releases cortisol is that you get an accompanying rush of glucose (blood sugar) to give you extra energy. Since thinking about your romantic partner can increase stress hormones like cortisol, it may follow that you can also get a glucose boost from thinking about your partner.
