The stress hormone explained in plain English – no biology degree required
What Is Cortisol? The Body’s Built-In Alarm System
(And How to Stop It Ringing All Day)
Cortisol isn’t bad — it wakes you up, gives you energy, and helps you handle tough moments. Problems only start when it stays high all day. Here’s exactly what cortisol is, how it works, and 6 dead-simple habits that bring it back to normal — fast.

How Your Body Turns Stress Into Cortisol
(5-Step Chain)
Brain spots danger (deadline, argument, loud noise)→
amygdala hits the alarm button
Hypothalamus
yells at the pituitary gland
Pituitary
releases ACTH into the blood
Adrenal
glands pump out cortisol
Cortisol
gives you super-hero energy… but only meant for minutes, not hours
The whole system is called the HPA axis — your personal stress highway.
The Natural Daily Cortisol Curve
(What It Should Look Like)
  • 6–8 am → big healthy peak (you feel awake and ready)
  • Noon → already dropping
  • 4 pm → nicely low
  • 10 pm → almost zero (so you can fall asleep easily)
If your curve looks flat in the morning and high at night → classic sign of chronic stress.
