The science of CalmCarry® in plain words
What you feel, why the middle of the palm, what the research shows, and how to use it.
In one breath
A soft pulse in your palm, for twenty minutes
Hold CalmCarry® in your palm for twenty minutes and feel a soft pulse at the centre of your hand, like a tiny heartbeat. The spot is one Chinese medicine has pressed for calm for over a thousand years, and it sits over the median nerve, so your brain notices.
A steady rhythm to rest a busy mind on, and something to hold instead of your phone.
- Twenty minutes, then it switches itself off
- Press once
- Nothing to swallow
- No app, no subscription
- USB-C, about 50 sessions per charge

How CalmCarry® works
CalmCarry® is a small handheld device you rest in the palm of your hand for twenty minutes. Hold the side button for about 5 seconds, turn it metal-side down into your palm, and it delivers gentle microcurrent pulses to the centre of the hand. After twenty minutes it switches itself off. Eight intensity levels on both the Adults and Kids devices, no app, and nothing to swallow.
What you feel
A soft, steady pulse at the centre of your palm. It is distinct for the first minute, then settles into the background. At the lowest level it is clearly noticeable without being sharp. Most people find level one is enough.
Where it works
The pulses land on the point at the centre of the palm known in Chinese medicine as Laogong, or PC8, used for more than two thousand years to calm the mind. Modern anatomy explains why the spot was chosen: the skin there is dense with touch receptors, all served by the median nerve, one of the main nerves running from the hand to the brain. A gentle pulse at that point is a clear, regular signal, and the brain registers it within a fraction of a second.
What the signal does
It gives a busy mind something to rest on
A racing mind at night is mostly attention with nowhere to settle. A steady rhythm in the hand gives it a place to go, so worries have less room. Research on falling asleep shows that giving attention a concrete anchor shortens the time it takes to drift off.
It keeps hands and attention off a screen
Phone use in the half hour before bed is one of the best-documented causes of poor sleep, in adults and children alike. Twenty minutes holding CalmCarry® is twenty minutes not scrolling.
It becomes a cue
Because it is the same object, the same twenty minutes, at the same time each night, your body learns that this is the wind-down. A consistent bedtime routine is one of the most reliably proven ways to fall asleep faster, and CalmCarry® has that routine built into the hardware.
On the tradition
The palm point CalmCarry® reaches has been named in Chinese medicine for more than two thousand years and used to "calm the spirit". That is a tradition, not a proof. Modern research has tested pressing and stimulating points on the hand and wrist for calm and sleep, mostly in adults before operations, and found short-term reductions in worry and modest improvements in self-rated sleep. Those studies used finger pressure or clinical stimulators, not CalmCarry®, and CalmCarry® itself has not yet been tested in a clinical trial. We will say so plainly until it has, and we will publish the result whatever it says.
On expectation
Part of how any calming ritual works is that you stop, you expect it to help, and you do the same thing every night. That is true of CalmCarry® too, and we would rather say so than pretend the pulse does all the work. It does not make the calm less real. It means the twenty minutes matter as much as the device.
How to use it
Four steps, no setup, nothing to download.
-
Switch it on
Press the power button on the side edge. Start on the lowest level; most people never need more. The plus and minus buttons adjust it if you do.
-
Rest it in your palm, metal-side down
The pulse should land in the centre of the palm. Make a loose fist: the spot your middle fingertip touches is the one.
-
Hold it for twenty minutes
Lights low, phone out of reach. You feel the pulse clearly for the first minute, then it settles into the background while you wind down.
-
Let it switch itself off
After twenty minutes the session ends on its own. Same time every night, and it becomes the cue that the day is done.

What it isn't
CalmCarry® is not a sedative and does not put you to sleep. It is not a medical device and does not treat any condition. Nothing goes into your body, and there is no app or subscription.
Many of the people who use it tell us they feel themselves settling within the session; for others it takes a week or two of nightly use. If it does not help you within 100 nights, send it back.

Questions, answered
Straight answers from the Glowco team.
How does CalmCarry® work?
Rest it metal-side down in the palm, hold the side button for about 5 seconds, and it delivers gentle microcurrent pulses to the centre of the hand for twenty minutes, then switches itself off. You feel a soft, steady pulse that settles into the background; most people find the lowest level is enough. The full explanation, with the research behind it, is in How CalmCarry® works above.
How long until I notice anything?
Many people tell us they feel themselves settling within the session. For others it takes a week or two of nightly use, because part of what CalmCarry® does is become a cue your body learns. If it has not helped you within 100 nights, send it back.
Is it only for bedtime?
No. Bedtime is where most people start, but it is small enough for a pocket or a bag, and customers tell us they use it before a meeting, in the car, on flights and through big feelings during the day.
Is there anyone who should not use it?
CalmCarry® is a wellness device, not a medical one. Do not use it if you have a pacemaker or other implanted medical device, a heart condition, or epilepsy or a seizure disorder, or if you are pregnant. Don't use it on broken or irritated skin (cuts, eczema, blisters or peeling), or in humid places like the bathroom. If you have a medical condition, check with your doctor first.
Is this the official CalmCarry® store, and are the reviews real?
Yes. theglowcompany.co is Glowco's official store, and every order from here includes an authenticity certificate. The reviews on our pages are collected by Okendo from verified buyers, so every quote comes from a real customer order.
What does it feel like?
A soft, steady pulse at the centre of your palm, like a tiny heartbeat. It is distinct for the first minute, then settles into the background. At the lowest level it is clearly noticeable without being sharp.
Which hand should I use?
Left hand in the evening, right hand during the day. CalmCarry® starts on the slow pulse, which goes in your left hand for winding down at night. Press the power button once more for the faster pulse, which goes in your right hand during the day.
Is it safe for children?
CalmCarry® Kids is made for ages 3 and up, with adult supervision recommended for younger children. It has the same pulse and eight levels as the Adults device, there is nothing to swallow, and you set the level. Start on the lowest, and your child can say "too much" at any time.
How does it charge, and how long does the battery last?
It charges with the included USB-C cable, the same cable as most modern phones, and a full charge takes about 2 hours and gives about 50 twenty-minute sessions.
How does the 100-day guarantee work?
Use your CalmCarry® for up to 100 days. If it is not for you, for any reason, send it back for a refund. Our support team will walk you through the return.
