SYNE

Every English speaker has sung a word most of us don't define.

Auld lang syne. For the sake of old long since. It lives at the turn of every year, in the song that carries what we keep across the threshold. Syne means since — the continuity preserved, the time kept.

Recovery is not a single night. The body that is well this morning is well since last night. The body with reserves to run the week is in reserves since the month of sleep that built them. The body that ages with clarity is in that state since the years of practice that made it so. The night is where the work happens. The practice is where the result accumulates.

Modern sleep science — deep-stage measurement, heart-rate variability, glymphatic clearance, hormonal rebalancing — has spent a decade proving what the old word already named. What compounds is what is kept.

Syne is the brand built for the practice. A clinical evening sachet, mixed with water, taken at the hour the body asks for it. Thirty sachets a month, thirty nights of keeping. A wearable-linked app that reads your sleep, your HRV, your data, and measures what compounds when the practice is kept.

One word, old as Burns. One ritual, kept.
