What arrives
Four things, every time.
- 01
One concept
A single mechanism explained in plain language — what your body is doing, and why the timing of it matters.
- 02
One experiment
A specific adjustment with a specific time attached, small enough to run for a fortnight and reverse if it does nothing.
- 03
One piece of research
Something recent, with what it found, who it was measured in, and how much weight it deserves.
- 04
One seasonal note
What the current stretch of the year is doing to your light exposure, and what that tends to shift.
What we will and will not do.
