Heart Chakra can manifest in our physical health through heart problems, asthma, and weight issues. But blocks are often seen even more clearly through people’s actions. 
People with heart chakra blocks often put others first, to their own detriment. It’s the middle of the seven chakras, so it bridges the gap between our upper and lower chakras, and it also represents our ability to love and connect to others. When out of alignment, it can make us feel lonely, insecure, and isolated.
