If there’s a sports lover in your life – don’t get on their case for watching pre-season football, or following their favorite baseball or soccer team. And if you’re the sports fanatic – tell your partner to chill out. Because, according to a study, sports fans get a 50% spike in happiness when they watch their favorite teams compete. It’s because, even though we’re not playing ourselves, willing our team to win makes us feel as if WE’RE trying to win. And that gives us a surge of energy, a mood boost, and an extra dose of a certain self-esteem-building hormone.
