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.

The problem

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 tonight
🌙

Melatonin

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 mechanism
📱

Sleep 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 symptom
The mechanism

Your body already knows how to switch off.
It just needs the signal.

01

Fill the bath

Add one scoop of Tune. Hot — not scalding. You want your body temperature to actually rise.

02

Soak 20 minutes

Your core body temperature climbs by ~1–1.5°C. Your body registers the heat and starts preparing a response.

03

Step out

Tune Sleep's cool-down effect is the signal your brainstem reads as "time to sleep."

04

Same time tomorrow

The cue compounds — watch it show up in your sleep score.

Based on thermoregulation research from Horne & Reid (1985) and Kräuchi et al. (1999). Not transdermal absorption.

Ingredients

Three minerals. Nothing else.

No stimulants, no synthetic fragrance, no fillers. Here's the full list — in plain English.

Magnesium chloride

Pharmaceutical grade

The 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 minerals

Added 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-fragrance

A 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.

By the numbers

The ritual, measured.

20
minutes

The soak window. Long enough to raise your core temperature meaningfully. Short enough that you'll actually do it.

1°C
temperature drop

The rapid core temp drop after you exit. That's the precise signal your brain uses to trigger sleep onset.

$5
per bath

Less than a coffee. 12 baths per bag. The only 20 minutes of your evening nobody can interrupt.

30
days guaranteed

If you do the ritual every night for 30 days and your sleep doesn't improve, full refund. No questions.

The research

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.

Common questions

Answered honestly.

Oral magnesium takes weeks, if it works at all — it has to survive your gut and build up over time, and absorption varies wildly. Tune Sleep works tonight, because it doesn't depend on absorption. It works through temperature: the soak raises your core temp, and the cool-down that follows triggers sleep onset. That's why it can work the first night when oral didn't in six months.
Tune Sleep works through temperature, not absorption — the soak raises your core temp, the cool-down triggers sleep onset. The minerals make the water worth twenty minutes of your night, which is what keeps the ritual alive.
The temperature mechanism needs a bath you'll actually take every night — and that's the difference. Tune Sleep's pharmaceutical-grade magnesium chloride makes the water dense, silky, and consistent batch to batch, turns the soak into something you look forward to, and backs it with a 30-day guarantee so you can test it against your own sleep data. A scoop of plain salt can't hold a nightly ritual together. Tune Sleep is built to.
We'd ask you to check with your GP or midwife before adding any new product, including Tune. A warm (not hot) bath is generally fine in pregnancy, but "hot" is the operative word for our mechanism — and hot baths in pregnancy carry real risks. We're not the right place for that call.
Some people notice it in the first few nights — the act of being in a hot bath and getting out already triggers the thermoregulatory response. For the ritual cue to become conditioned (the part where your nervous system learns to expect sleep), allow 10–14 nights of consistency. That's why the guarantee is 30 days, not 7 — long enough to see the trend in your sleep tracker.
30 days, full refund. Email us and we'll process it without questions. The mechanism is real — but we know bodies and habits are individual, and we'd rather give you a money-back guarantee than a hedge-everything disclaimer.
Magnesium chloride baths are commonly used for children, and the ingredients in Tune are gentle. That said, we formulated Tune for adults and the "hot bath" protocol isn't appropriate for young children. Ask your GP if you're considering it for a child under 12.
