Why Hormones Need Steady Cues
When mood, sleep, or energy feels whole-body, think hormones, not just thoughts. The pituitary gland sits under the brain and helps relay hormone signals.
The Science
- Harris (1948), Physiological Reviews: the hypothalamus controls the pituitary through releasing hormones in a dedicated portal blood supply.
- The pituitary then relays signals that influence growth, stress, thyroid, reproduction, and metabolism.
- Hormones change on slower rhythms than a sudden feeling, so one pep talk rarely fixes a drained system.
- When mood or energy feels whole-body, think hormones, not just thoughts.
The Protocol
- Steady cues: give your brain bright morning light.
- Keep sleep and meals as regular as you can.
- When stress hits, use slow breathing before the next decision.
- Notice the signal, name the mechanism, and change one input before autopilot.
