Living in survival mode has a severely negative impact on growth and on the brain/thinking. This is why poor people often stay poor and make bad decisions. The brilliant stem cell biologist Dr. Bruce Lipton describes in chapter 6 of his book “The Biology of Belief” why an organism cannot simultaneously be in a state of growth and protection:
"By now you won’t be surprised to learn that I first became aware of how important growth and protection behaviors are in the laboratory where my observations of single cells have so often led me to insights about the multicellular human body. When I was cloning human endothelial cells, they retreated from toxins that I introduced into the culture dish, just as humans retreat from mountain lions and muggers in dark alleys. They also gravitated to nutrients, just as humans gravitate to breakfast, lunch, dinner and love. These opposing movements define the two basic cellular responses to environmental stimuli. Gravitating to a life-sustaining signal, such as nutrients, characterizes a growth response; moving away from threatening signals, such as toxins, characterizes a protection response. It must also be noted that some environmental stimuli are neutral; they provoke neither a growth nor a protection response.
My research at Stanford showed that these growth/protection behaviors are also essential for the survival of multicellular organisms such as humans. But there is a catch to these opposing survival mechanisms that have evolved over billions of years. It turns out that the mechanisms that support growth and protection cannot operate optimally at the same time. In other words, cells cannot simultaneously move forward and backward. The human blood vessel cells I studied at Stanford exhibited one microscopic anatomy for providing nutrition and a completely different microscopic anatomy for providing a protection response. What they couldn’t do was exhibit both configurations at the same time. [Lipton, et al, 1991)
In a response similar to that displayed by cells, humans unavoidably restrict their growth behaviors when they shift into a protective mode. If you’re running from a mountain lion, it’s not a good idea to expend energy on growth. In order to survive — that is, escape the lion — you summon all your energy for your fight or flight response. Redistributing energy reserves to fuel the protection response inevitably results in a curtailment of growth."
In other words, living in a constant state of survival (as unsteady income might cause), severely restricts a person’s capabilities to grow in a healthy way.
