When stress is a constant hum, hormones like cortisol reorganize to focus on one thing: survival. This reorganization takes a toll on how you think, feel, and function – and even how you sleep. The effects ripple outward quietly, showing up as mood swings, exhaustion, and a body that feels like it’s working against you.
But once you understand the biology driving it all, the chaos starts to make sense – and so does the path out.
The Pregnenolone Steal Explained
Pregnenolone is like the “active ingredient” used by the body to produce most of its hormones (cortisol, progesterone, DHEA, and others). Imagine being on a shared budget. Under regular circumstances, that budget is spread out amongst various hormonal requirements. When you are under constant stress, your HPA (hypothalamic-pituitary-adrenal) system, which is responsible for managing stress, reallocates most of the pregnenolone for the production of cortisol.
This phenomenon is often referred to as the pregnenolone steal and it is not a glitch in the system. Your body is doing exactly what it is designed to do. Cortisol helps you stay awake, moving, and reacting to danger. Biologically, that is more important than reproductive hormones.
The issue is that modern stressors such as financial burdens, overworking, and lack of sleep, are not completely turning off. The signal of danger remains on. Your body keeps making cortisol at the expense of progesterone and DHEA, leaving these hormones on the low side.
When compared to estrogen, low progesterone leads to a condition known as estrogen dominance. This doesn’t only affect women, but also anyone who has had their adrenals activated for an extended period. Symptoms of estrogen dominance include mood swings for what feels like no reason, consistent bloating, high or missed periods, sleep irregularities, and an emotional sensitivity that’s difficult to describe to someone who hasn’t experienced it.
The Role Of Topical Herbal Support
In addition to the nervous system self-regulation practices, the body can be supported through certain plant compounds as it works its way out of a more chronic stress state. Wild yam contains diosgenin, which has been used traditionally as a phytohormone to help in situations where stress has led to lowered progesterone activity relative to estrogen.
Topical application is a gentler delivery method than oral supplementation for many people, and doesn’t create any additional work for a gut that most likely doesn’t need it at that moment. Solutions like wild yam comfort cream by Naturally Linda is one of the many topical products that can be applied directly to the skin for transdermal absorption where needed.
The adaptogenic herbs, ashwagandha and rhodiola, also contain compounds that can help the body adjust its HPA axis response over time when consistently used, in the sense that their presence can create an impression of lower levels of stress to the system and in turn cause the stress hormone signal to be reduced.
How Stress Hits The Thyroid
Cortisol doesn’t just affect the adrenals; it also blocks the signal to the thyroid to secrete its hormone. In this case, it specifically reduces the thyroid-stimulating hormone, causing a slowing of the metabolic process.
This is one reason people experience the “tired but wired” sensation. Their adrenals keep pumping out stress hormones – they feel wired and on edge – but their thyroid has been turned down, resulting in decreased energy, body temperature, and the feeling that they can’t get enough sleep even when they’re exhausted.
A disrupted circadian rhythm further exacerbates this response. Cortisol should be high in the morning to get you up and running and low at night to help you unwind and prepare for sleep. Chronic stress raises cortisol across the board and leads to people feeling “tired but wired.” They may be alert at midnight, but then completely foggy until 9 am. This disrupts other hormonal systems associated with sleep and the sleep-wake cycle.
A Bottom-Up Approach To Recovery
Most advice on hormonal balance starts at the top: supplements, dietary protocols, lab panels. Those have value, but they skip the layer underneath. If the nervous system is still perceiving threat, the body won’t fully release its grip on cortisol production. No supplement can override an active threat response.
Somatic practices address the foundation. Slow diaphragmatic breathing – specifically extending the exhale to twice the length of the inhale – activates the parasympathetic nervous system directly. Time spent in natural environments, sometimes called forest bathing, has measurable effects on cortisol levels. These aren’t soft recommendations. They’re inputs that change the internal chemical environment.
The goal is to send the body a consistent signal that the threat has passed. Only then can the endocrine system begin redistributing resources away from survival and back toward maintenance.
What Sustained Effort Actually Looks Like
Between 75-90% of all doctor’s office visits are for stress-related complaints and ailments (American Psychological Association). That statistic shows how deeply this impacts everyday health, not just mood.
Healing hormonal disruption triggered by stress is not linear. Your body doesn’t automatically restore hormonal balance the same month you begin meditating or sleeping more deeply. Progesterone production, thyroid function, and the rhythm of our cells; these all operate on longer timelines. Weeks, perhaps more accurately stated as months, not days.
What changes things is continuing to show up for these practices over and over again. This builds an unspoken safety in your physiology. Your body has become good at one thing: Survival. Now, it can come back to homeostasis.
