How cortisol wrecks progesterone (and your mood)
â Itâs not just âstress is bad for hormones.â
Itâs metabolic triageâŚand progesterone loses.â¤ď¸âđŠš
When your body is under chronic stress, it triggers your HPA axis to release CRH â ACTH â cortisol.
But hereâs the biochemical catch:
đ§Ź Cortisol and progesterone both need pregnenolone (their hormonal âmotherâ).
In a calm, nourished state? Your body can produce both.
In a high-stress state? Your body steals pregnenolone to pump out more cortisol.
This is known as âpregnenolone steal.â
Why does it matter?
âŹď¸ Chronically low progesterone shows up as:
â Heightened anxiety or low mood
â Shortened luteal phase
â Heavier or more erratic cycles
â Trouble sleeping (especially post-ovulation)
â Fertility issues
â Feeling âwired but tiredâ
Progesterone is your calm, grounding hormoneâŚit balances estrogen, soothes the nervous system, and promotes deep sleep.
Without enough of it, you feel emotionally fragile, hormonally unstable, and more reactive to stress.
And the spiral continues.
đĽ More stress â Less progesterone â More symptoms â More stress.
This isnât a hormone deficiency problem. Itâs a safety signal problem.
Your body knows exactly what itâs doingâŚit just thinks youâre in survival mode.
Rebalancing your cortisol rhythm doesnât mean quitting life.
It means repairing the foundations:
âď¸ Eat within 60 minutes of waking: protein, fat, and salt to calm the HPA
âď¸ Ditch intermittent fasting if youâre in burnout
âď¸ Support with adrenal minerals (Na, Mg, K)
âď¸ Use light, breath, and rhythm to retrain cortisol flow
âď¸ Sleep. Even a 20-min nap counts.
âď¸ Buffer blood sugar swings, especially mid-afternoon
âď¸ Reduce blue light at night (cortisol blocker = progesterone preserver)
Progesterone is built in safety, not in hustle.
And healing your mood may start with healing your morning.
