General Adaptation Syndrome (GAS) describes the body’s biological response to prolonged stress. It unfolds in three stages: alarm (activation of the sympathetic nervous system and stress hormones like cortisol), resistance (ongoing physiological adaptation to maintain functioning), and exhaustion (depletion of regulatory systems when stress is chronic). Over time, this sustained activation can disrupt immune, endocrine, and nervous system functioning—helping explain burnout, anxiety, and stress-related illness.
If you grew up in unfavorable conditions, where there was a threatening adult, societal stress, a not safe home or environment, your brain as an adult will be on higher alert.
And if you’re a highly sensitive person, environment is really important. Highly sensitive people really take in more of their environment and that could be extremely regulating or dysregulating for your nervous system.
As adults, we have certain choices now. And I understand that there are hard life circumstances that we all have to deal with. If you are able to make your environment more healthy for you now, I would highly recommend you do that.
But also many people who grow up in chaotic environments as children not only was the outside chaotic, The inside was chaotic too. And the inside is still chaotic.
What you can work with is the inside. Helping yourself to find inner safety within your body through grounding or orienting or comfortable sensory stimulation. This is the bottom up message to your brain that you are safe now.
Whether you have a trauma history or are also a highly sensitive person I hope to share more tools here to support your inner system so you can help yourself to make your outside environment, more healthy, and safe for your brain and your spirit.
