Emotions carry weight. In more ways than you think. As stated beautifully by Jennifer Weinberg, "The beliefs you hold about yourself and the world, your emotions, your memories and your habits all can influence mental and physical health."
There is a connection. Your mental, spiritual and emotional state show up in your body. And on your body. Emotional baggage is literal. Keeping your insides healthy is critical. If you take care of that, it automatically shows up everywhere else.
