Summer is at last well and truly over. It is still quite mild during the day, but the trees are well into shedding their leaves and our bodies are preparing themselves for the cold of winter. Metal is the element of Autumn. If our Metal energy is low, we may have problems with breathing and with bowels. There are a lot of sore throats and coughs around at the moment, which is a sign of our lungs being vulnerable and sensitive to the sudden changes in temperature.. Emotionally we may have difficulty identifying and maintaining boundaries.
