Friendship is not just about fun and company. Studies indicate that having friends can improve physical health too. Research from Michigan State University in 2017, revealed that friendships are more likely to influence mood than family. Prolonged stress can put your long term health at risk. A 2016 report from the London School of Economics suggested that "people's happiness was more closely related to relationships than the size of their wallet". Friends provide emotional support and enhance psychological well-being. Even if they cannot solve major problems, they cheer you up by being supportive and making you feel you are not alone. Next time you feel low, reach out to your BFF, to get into a positive mood.
