"Exhaling a few times through the AIKI necklace already has a relaxing effect. I especially like this thing because it hangs around your neck, reminding you throughout your day to consciously calm your breath (it quickly flies out of control otherwise, I know from experience, you just forget about it). You don't need any other technique for it, it's not too expensive, and such a necklace looks nice too."

Nikki van der Velden, Breathing Expert & Founder The Breathwork Movement

"The breath, indescribably powerful. As a breath therapist, I strongly believe in the power of the breath. The AIKI necklace is my anchor, my reminder, to return to myself. I use it especially for the "calming breath": 4 seconds of inhaling through my nose to my belly, and then slowly exhaling through the necklace. Magical! I think AIKI is the most genius jewelry brand of our time. At a time when stress and burnout complaints are on the rise, AIKI offers peace and balance."

Jiska van den Brink, Coaching & Breathwork Expert

"AIKI Breathing Tool, this made me happy when I used it for the first time. I know from experience and practice that sometimes in the beginning of recovering breathing it can be difficult to do this alone with exercises. A tool, product, resource can be a tremendous support in this. AIKI is one of those resources that you can simply wear around your neck. The one that helps you take a moment to remember, that brings you back into the moment after a few breaths and lets your gas pedal take over again. But also in exciting situations, crowded spaces, large crowds, AIKI is a resource. When your breath shoots up and in some cases panic can set in, breathing through AIKI brings you back into the calming breathing frequency."

Eline Thomaes, Orthomolecular therapist & Breathwork expert

"For me, the AIKI Breathing Tool works ideally as a reminder to myself to take moments throughout the day to stop and focus on my breathing, You don't necessarily need the tool to slow down your breathing, but it is helpful in doing so. Especially when you are starting out and to help you make it a habit. This way you create moments during the day to breathe. And those are very valuable!"

Important tool for breathing regulation

Daphne van Schaik

The necklace helps me to calm down and grab focus at times when I need it. For my students I teach, it is also a really nice and easy way. It's so easy and nice that I can recommend it to anyone!

David Rüben

Used several breathing tools but always not the hoped-for result. I recently purchased the AIKI Solid Square - Space Gray, mainly because I really like the design of the product. I have been using the Solid Square for about 1 week now and my breathing has become noticeably calmer. Am curious to see what it will do in the longer term.

What is the AIKI Breathing Tool?

The AIKI Breathing Tool is a necklace specially designed and developed to extend and slow down your exhale. By inhaling through your nose and exhaling through the Breathing Tool automatically your exhale will extend and will be deeper. As a result of this you will bring your body and mind to rest within seconds.

How does the AIKI Breathing Tool work?

With the AIKI Breathing Tool we let you breathe more consciously. Human breathing is directly affected when we experience stress or anxiety. We start to "over breathe" in a wrong way, what a negative impact has on our body processes. By breathing in through your nose and exhaling through the Breathing Tool the exhale will automatically be extended and deeper. An extended exhale stimulates our vagus nerve. When this happens our heart rate will slow down and our blood pressure will decrease. As a result of this our body and mind will relax within seconds in an organic way.

To achieve the best and most effective results, we created the AIKI Cycle: inhale through your nose for 4 seconds, hold your breath for 7 seconds, exhale through the breathing tool for 8 seconds and relax for 4 seconds. The cycle is based on the by scientifically proven breathing techniques.

Hoe vaak en hoe lang mag ik de ademhalingstool gebruiken?

Over het algemeen wordt aanbevolen om dagelijks een paar sessies in te plannen, bijvoorbeeld 's ochtends en 's avonds. Dit helpt om consistentie te behouden en de voordelen van diepe ademhaling te maximaliseren.

De duur van elke ademhalingssessie kan ook variëren, maar experts suggereren dat zelfs enkele minuten per sessie aanzienlijke voordelen kunnen bieden. Een veelgebruikte techniek is de "4-7-8" ademhaling, waarbij je 4 seconden inademt, 7 seconden je adem inhoudt en 8 seconden langzaam uitademt. Dit kan meerdere keren worden herhaald, afhankelijk van je voorkeur en beschikbare tijd.

In het algemeen zou 5 tot 10 minuten per sessie ruim voldoende moeten zijn om het gewenste effect te behalen.

What material is the AIKI Breathing Tool made of?

The AIKI Breathing Tool is made of high-quality stainless steel, to be precise: stainless steel 316L. This type of material is known to be very resistant to corrosion and is also widely used in the medical world for surgical instruments. The Breathing Tool is therefore also water-resistant and will not discolour on contact with water/seawater.

Is this breathing exercise really scientifically proven?

In recent years there have been several studies done about breathing exercises all over the world. It has emerged that daily breathing exercises have several benefits, including: lower cortisol levels, decreased heart rate and blood pressure and improved sleep. The AIKI breathing tool has been developed to help you learn to breathe more slowly so that this eventually becomes a habit for you. Because the breathing tool is also designed as a necklace, you are automatically reminded to do your daily breathing exercise as soon as you wear it.

The idea comes from the phenomenon of 'pursed lip breathing'. One way to do this is to breathe out through a straw. We used the straw as the basis for the design of the Breathing Tool (hence the elongated shape). For years, experts have recommended this technique for panic and anxiety attacks because you can breathe out longer and slower. This calms your breathing and eliminates stress and anxiety. The American Lung Association additionally recommends this breathing technique for people with tightness symptoms such as COPD or asthma, for example.
