Stressed Out: Causes, Effects and Keeping Calm

Chronic stress makes people sick. The fight-or-flight response activates our bodies to face immediate threats, but that stress system must turn off to allow organs to recover. Constant anxiety keeps the system active, and in this eBook, we examine the effects of ongoing stress and trauma on both body and mind as well as ways to arm ourselves against adversity by managing stress and building resilience.

In this eBook, we examine those impacts on the planet, on human society and on the plant and animal kingdoms, as well as effective mitigation strategies including resourceful urban design and smart carbon policies.
