If you’re optimizing health, skip the Bluetooth wearables.

Most trackers sit directly on your skin and pulse non-native EMF 24/7 — not ideal for mitochondria, sleep, or hormones.

A low-tech approach actually gives you cleaner signals from your own biology.

Pen + paper for sleep, movement, sunlight, hydration, and mood beats another always-on device.

If you want metrics, use an old-school heart-rate chest strap (Bluetooth off) or choose a device that stays in true airplane mode.

Just keep in mind: it’s easy to get more connected to the data than to yourself.

Remove the middleman + the noise and your body will communicate with you as long as you’re listening.

I’m surprised signal hasn’t taken off more
