"We perceive our own bodies in many different ways. We can look at our bodies, feel touch on our bodies, and also feel our body from within, such as when we experience our hearts racing or butterflies in our stomachs. It seems that a stable perception of the body from the outside, what is known as "body image," is partly based on our ability to accurately perceive our body from within, such as our heartbeat."
Could it be that the disconnection from our bodies that comes with our distracted, busied way of living creates fertile ground for body dysmorphia? Try this: Find a quite place, close your eyes, place one hand over your heart and the other on your belly (eek!), and breathe deeply from your belly for 5 minutes or go for a walk, ask for a hug, or rub your sweetie's shoulders. These little moments of intentionally connecting with your body may help.
