We put our adrenals through the ringer everyday - sometimes without even knowing it.
In normal situations, our bodies adapt nicely to stress. When the brain perceives stress, it triggers hormone production that activates “fight-or-flight” mode. The adrenals are the glands that release the stress hormone, cortisol, that helps up respond to threats. The threat goes away, and things go back to normal.
But what happens when you’re under chronic stress?
Our bodies steal hormones away from normal functions to divert them toward producing cortisol. It’s ultimately a priority game: grow beautiful hair vs. run from a bear and live? Our brains & bodies will choose survival every time.
When we’re under chronic stress, normal body functions get put on the back-burner so we can put all of our energy toward surviving.
No big deal, right? Here are some of those normal body functions: digestion, wound repair/recovery, tissue repair, hair/skin/nail growth, liver detox, gallbladder function, proper immune system regulation, blood and oxygen circulation, generation of neurotransmitters in the brain.... all activities our bodies need to thrive!
We're Amazingly Designed to Adapt to Stress...
This might sound incredibly broken, but it's actually amazing design! When the threat persists for a long time, however, our bodies will keep on working overtime to produce more cortisol, eventually depleting/halting production of the hormones we need in order to get enough cortisol for us to live. Let’s face it - we live in a world where stress means getting caught in traffic or being behind schedule, and not necessarily fighting/fleeing for our lives.
But, any of these modern-day experiences can throw us into survival mode long just enough to keep the stress and hormone response up for a prolonged period of time.
When our stress response is activated, production of hormones like DHEA and progesterone become imbalanced. Conditions associated with low DHEA and progesterone include autoimmune diseases (rheumatoid arthritis, fibromyalgia), depression, hypothyroidism, infertility, and anxiety, to name a few.
When Cortisol Is High For Too Long...
Real damage occurs: body tissues break down and we experience nutrient depletion (like glutamine, critical for maintaining a healthy gut lining) and compromised immune function. We chew through vitamin D much more quickly, liver function gets put on hold, and we might even store extra belly fat as a safety mechanism for survival. Poor wound healing, mood, and memory problems are also common.
Eventually, cortisol nearly runs out completely. But it’s not that the adrenals are “fatigued” and can't work anymore - that's an inaccurate label. Instead, the brain actually shuts down the adrenals' signal for more cortisol production to protect us from further damage.
If we haven’t listened up until this point, this is when our bodies are screaming even louder for a break.
This is the point where I imagine my body as a talking computer, saying, "Initiating shutdown sequence in 5... 4... 3... 2......." Motivation might wane, brain function may not be optimal, and we might feel depressed or lack of joy in things we used to love. Inflammation may also increase during this phase. In many cases, the fatigue is the most notable and crippling symptom. It is time for rest!
In all phases of chronic stress and adrenal stress….. things just don’t feel right.
Five Ways to Stress Your Adrenals
Mental & Emotional Stress
This is what we think of when we hear the word “stress.” Any emotion such as grief, fear, anger, or anxiety could be considered stress. Whenever we’re in new situations, feel helpfulness, or feel like we can’t control the outcome can also contribute to this type of stress.
Blood Sugar Swings
I like to call this the blood sugar rollercoaster, when blood sugar soars high and dips low. Whenever we eat high-carb / high-glycemic load foods, our bodies release a large amount of insulin to react and clear out that blood sugar high… which then results in an enormous blood sugar low. Doing this over and over again can add tremendous strain on the adrenals.
When researcher cause adrenal dysregulation in animals to study them further, the go-to strategy is sleep deprivation. Sleep is the magical time when tissues are repaired, and important growth hormones are generated. Sleep apnea can also contribute to non-restorative sleep.
Overtraining & Too Much Exercise
Take it from someone who used to run 10+ miles a day and race for up to 20 hours at a time: exercise can be a great thing, but under chronic stress, it can be a burden on the body and not a benefit. Cardio and endurance-focused exercise is most commonly associated with adrenal dysregulation (and intense exercise:
