PRODUCT DETAILS

  • Handheld microcurrent (CES) sleep device — gentle electrical stimulation via palm contact

  • 9 intensity levels — adjustable via +/− buttons

  • 3 modes on LED screen: Sleep, Soft, Excited.

  • Built-in 500–800mAh battery, 12+ hours per charge, Type-C charging

  • Matte texture finish, ergonomic palm-grip shape.

HOW TO USE IT

  1. Charge fully before first use (Type-C, approx. 1–2 hours).

  2. 15–20 minutes before bed: sit or lie in a dim, quiet space.

  3. Hold the device in your palm with the metal contact points touching your skin.

  4. Press the power button. Select Sleep mode.

  5. Begin at level 1. You will feel a gentle pulse. Stay here for 2–3 nights to allow your body to adjust.

  6. Increase to level 2 or 3 once level 1 feels subtle. Find the level where the pulse is present but does not compete with your thoughts.

  7. Set the device on the nightstand when ready for sleep — it auto shuts off at 20 minutes.

Important: Higher intensity is not more effective. The goal is gentle, consistent stimulation. Start low and stay at the minimum level that works for you.

    A cue to wind down

    A gentle microcurrent pulse you hold in your palm — a physical signal that the day is done, not a switch that forces anything.

    Start low, adjust to you

    Nine intensity levels across three modes. Begin at level 1 and settle on the setting that feels right — no number to chase.

FAQs

What does it actually feel like?

At low levels, a gentle tingling or electrical pulse in your palm. At higher levels, a more pronounced sensation. It should never feel painful. If any level causes discomfort, reduce immediately. The correct sensation is one you can hold for 20 minutes without focusing on it.

How is this different from high-end CES devices?

The technology is similar — both are CES (Cranial Electrotherapy Stimulation) devices. Premium clinical devices like Alpha-Stim cost $800–$1,000+, require prescriptions, and use earclip electrodes. The Sleep Signal uses the same general technology at a significantly lower entry point in a palm-held form factor. Results vary by individual, as with any wellness technology.

How long until I notice a difference?

Some users notice a difference on the first or second night. Most report meaningful changes within 3–7 nights of consistent use. Use it at the same time each night as part of a wind-down routine — consistency of timing appears to strengthen results.

Can I use it if I have a pacemaker or medical implant?

No. The device uses low-level electrical current and must not be used by anyone with implanted electrical devices (pacemakers, cochlear implants, etc.) or skin conditions, wounds, or eczema on the palms. If you are pregnant or under care for a neurological condition, consult your doctor before use.

Why start at level 1?

Level 1 is where most people find their effective baseline. Higher levels are not inherently more effective — they are simply more intense. Starting low lets your body respond to the minimum effective stimulus. Many regular users settle permanently at levels 2–4. Starting too high is the most common reason first-time users report discomfort.

Is it safe to use every night?

Yes, with normal use as described. The device is designed for nightly use. Auto shut-off prevents overexposure. Do not use more than one session per night.

  • Why a repeatable cue helps you wind down

    The hardest part of sleep is the transition — the mind not switching off. A consistent, physical ritual gives that transition a clear starting line: lights down, phone across the room, device in hand for a few minutes, then set it on the nightstand. It doesn't force sleep. It marks the moment you stop.

    The 20-minute wind-down ritual

    Lights dimmed. Phone on the charger across the room. Lying in bed or sitting in a chair. Hold the device. Feel the pulse. Breathe slowly — not because you are forcing it, but because the stimulation naturally slows your system. 15–20 minutes later, set the device on the nightstand. It shuts off on its own. You are already most of the way there. The ritual works not because it is dramatic, but because it is repeatable.
