Tune Sleep
Tune Sleep saturates a hot bath with magnesium and Dead Sea minerals. Soak 20 minutes; when you step out, Tune Sleep's cool-down effect cues sleep onset through your body's own mechanism. Deeper sleep, better recovery — no pills, no melatonin.

Your nervous system doesn't have a manual off-switch — it needs a signal. Tune Sleep delivers it: 20 minutes in a mineral-dense soak raises your core temperature, and the rapid cool-down when you step out triggers the sleep-onset signal your body already knows. No melatonin, nothing ingested, nothing that builds tolerance. Same time every night — that's the whole protocol.
- Run a hot bath — hot enough to raise your body temperature, not so hot it's uncomfortable
- Add one full scoop and stir briefly until dissolved
- Soak for 20 minutes. Same time every night for best results.
- Step out and go straight to bed. The cooling-down is the mechanism.
900g bag · 12 baths per bag · measuring scoop included
- Magnesium chloride flakes (pharmaceutical grade)
- Dead Sea salt
- Low-fragrance essential oil blend
No synthetic fragrance. No dye. No fillers. No stimulants. That's the whole list.
Tune Sleep works through thermoregulation — the most studied sleep-onset mechanism there is. We don't lean on skin-absorption claims; the minerals' job is the water itself: density, feel, and a ritual worth repeating.
Here's the mechanism: Tune Sleep raises your core body temperature; when you step out, it drops fast. That rapid drop mirrors the natural temperature decline your body uses to trigger sleep onset — a signal sleep researchers have pointed to for decades. Repeat it at the same time each night and Tune Sleep trains your nervous system to associate the cool-down with sleep.

If you tried magnesium before and felt nothing — here's why.
The supplement industry sold you the wrong story about sleep. Not the wrong ingredient — the wrong mechanism.
Oral magnesium
Has to clear your gut, get absorbed into the bloodstream, and wait weeks to build to meaningful serum levels — if your gut absorbs it at all. Most people's gut barrier lets less than 40% through. You took it for a month and felt nothing because it was working on the wrong timeline.
Doesn't work tonightMelatonin
Tells your body "it's dark outside" — but that's not what keeps you awake. You know it's dark. Your brain knows it's dark. The problem is you can't downshift from fight-or-flight. Melatonin addresses the clock, not the switch. And it builds tolerance within weeks.
Wrong mechanismSleep apps and white noise
Behavioural tools work on relaxation, not physiology. They're asking your mind to override a body that's still running hot. The temperature signal — the one your brainstem actually uses — never fires. You're trying to force sleep while the ignition switch is still in the wrong position.
Treats the symptomYour body already knows how to switch off.
It just needs the signal.
Fill the bath
Add one scoop of Tune. Hot — not scalding. You want your body temperature to actually rise.
Soak 20 minutes
Your core body temperature climbs by ~1–1.5°C. Your body registers the heat and starts preparing a response.
Step out
Tune Sleep's cool-down effect is the signal your brainstem reads as "time to sleep."
Same time tomorrow

Three minerals. Nothing else.
No stimulants, no synthetic fragrance, no fillers. Here's the full list — in plain English.
Magnesium chloride
Pharmaceutical gradeThe primary mineral in the formula. Pharmaceutical-grade magnesium chloride flakes dissolve completely in warm water and are consistent batch to batch. We don't use Epsom salt (magnesium sulfate) as the base — it's harsher on skin and less stable in water.
Dead Sea salt
Trace mineralsAdded in small amounts for the trace mineral profile (potassium, calcium, bromide) and the water-softening effect it has on the bath. Also makes the soak gentler for people with sensitive or dry skin. Not included as a magnesium source — the chloride handles that.
Essential oil blend
Low-fragranceA light blend — enough to carry a subtle scent during the soak, not enough to irritate. No synthetic fragrance, no dye, nothing that stings on freshly-shaved skin. If you're highly fragrance-sensitive, contact us — we can tell you exactly what's in it.
What we don't put in
No melatonin. No CBD. No adaptogens. No proprietary blends with undisclosed dosages. No dye to make it look more "mineral." No stimulants, no fillers, nothing that builds tolerance. The bag contains exactly three things — above — and we'll tell you exactly why each one is in there.
The ritual, measured.
The soak window. Long enough to raise your core temperature meaningfully. Short enough that you'll actually do it.
The rapid core temp drop after you exit. That's the precise signal your brain uses to trigger sleep onset.
Less than a coffee. 12 baths per bag. The only 20 minutes of your evening nobody can interrupt.
If you do the ritual every night for 30 days and your sleep doesn't improve, full refund. No questions.
Not a new idea.
Just an honest one.
Thermoregulation and sleep onset have been studied for 40 years. We didn't invent the mechanism — we just built a ritual around it and made the water itself something worth sinking into every night.
Horne & Reid (1985)
Showed that passive body heating through a warm bath significantly altered EEG sleep patterns — specifically the slow-wave sleep associated with deep, restorative rest.
Kräuchi et al. (1999)
Established the link between distal vasodilation (heat loss from hands and feet) and sleep onset latency — the faster your body sheds heat, the faster you fall asleep.
Haghayegh et al. (2019)
Meta-analysis of 13 studies confirming that a warm bath 1–2 hours before bed improved sleep quality, onset speed, and efficiency — specifically through the thermoregulatory mechanism.
