Diagram of how stress effects the body

Below is an illustration on how stress can effect us in our daily lives. While we often experience stress as just thoughts and feelings, this diagram demonstrates the actual effects of those thoughts and feelings on all the systems of the body, having the potential power and ability to cause great damage.

When you experience stress, often, without your awareness, your breathing becomes quick and shallow. In an instant of becoming aware of this undesirable state, one thing you can do to reverse this process, is to start breathing slowly and deeply. This very simple technique quickly sets you on the path of restoring balance and feelings of peacefulness.
Remember to Breathe!

Also, for the reduction of stress, the EFT posting could be helpful as well.
