This article explores what Blue Zone communities have in common, the science behind why these habits work, and seven practical steps you can take to bring Blue Zone principles into your own daily life.

As the days shorten and sunlight fades, four key hormonal systems come under pressure: vitamin D, serotonin, cortisol and melatonin.

The latest research confirms what Dr. John Lee and Dr. David Zava argued decades ago: maintaining healthy progesterone levels in proper balance with oestrogen is one of the most powerful tools women have for preventing and recovering from breast cancer. This article outlines seven practical steps to restore hormone balance and reduce breast cancer risk.

A landmark study published in Nature confirmed what Dr. John Lee and Dr. David Zava argued over a decade ago: natural progesterone — unlike synthetic progestins — can slow or even shrink ER+/PR+ breast cancer tumours.
