So like, what's your story? Obviously you have a bit of an accent, you're in a different time zone, right? So like, how did you get to train these athletes? How did you get to where you are today?
4:58
Um, long story short, essentially I was an athlete.
5:02
Um, and I think when you've got that athlete mindset, you really always trying to figure out what it takes to be your best.
5:11
But for me, the next question was when I no longer was an athlete and was becoming a health professional was like, well, how to athletes actually be their best.
5:20
And I trained as a physiotherapist and as a strength coach, but that wasn't what I was after.
5:24
I really wanted to know what is performance and what differentiates athletes.
5:28
the good, the great and like legends of sport.

So how do we do that?
10:25
If I'm right, it's CE certified medical device in the UK and Europe, while in the USA it's sold as a wellness device with FDA clearance still in process, correct? Correct.
10:37
Yes, this is correct.
10:38
And I'm really glad you asked this question because it can be really confusing.
10:43
And for me, as head of performance and working across both parts of the brand, it can be confusing in terms of what am I talking about, Neurosim or Neuropod.
10:52
But essentially, they are the same device.
10:55
The company is British-based and started in the UK.
11:01
So then the process started to get CE certification and it is classed as a medical device in the UK, in process to get FDA approval in the US.
15:41
So how does someone know what time and level of intensity to set their device to? I want to
27:36
What are, are there exercises? Are there, is this like a massage type thing? What is it you could do to help support that fascia, whether you're doing those things or not? Because I have heard it come up, but I just don't know what to do about it at that level.
27:52
So definitely massage is one way that people actually get help with their fascia.
27:59
The difference between getting a muscle massage and a fascia massage are quite different.
28:06
So the fascia massage is the one that you really don't want to have.
28:09
It's going to hurt a little bit more.
28:11
The tissue is a little bit more stiffer and can be quite uncomfortable.
28:15
So a lot of people quite often will go and get a massage, but they're just getting – the muscles worked on, not the fascia.

And so now when you're getting pulled in to work with a new athlete and understanding that it's always bespoke, like it's their story, whatever they're dealing with, what is typically the reason that they first reach out? And what is that kind of intake and first month and kind of ongoing process look like?

If I'm right, it's CE certified medical device in the UK and Europe, while in the USA it's sold as a wellness device with FDA clearance still in process, correct?
13:05
Yes, this is correct.
13:06
And I'm really glad you asked this question because it can be really confusing.
13:12
And for me, as head of performance and working across both parts of the brand, it can be confusing in terms of what am I talking about, Neurosim or Neuropod.
13:21
But essentially, they are the same device.
13:24
The company is British based and started in the UK.
13:30
So then the process started to get CE certification and it is classed as a medical device in the UK in process to get FDA approval in the US.
JohannaHOST
18:09
So how does someone know what time and level of intensity to set their device to? I want to start
8:09
So I understand these impacts directly the HRV, would you say?
8:15
Mm-hmm.
8:17
Yeah.
8:17
So essentially with Neuropod, like I was saying before, it's directly stimulating the nerve, the most superficial fibers at the ear.
8:26
Now, because of the location at the ear, the fibers sit just underneath the skin so we can access them direct.
8:34
But also the other thing is we're only targeting the fibers, what we call the afferent fibers.
8:39
So the Easy analogy again, if you think about you're in New York and you're trying to cross a one-way street and you're the message getting across the street versus a two-way street, it's a whole lot easier to cross the road when the traffic's only going in one direction.

7 MINS LATER

15:56
So for, let's say for someone like a regular executive or, you know, a high performer that works like nine hours a day, like what do you recommend could be like the ideal doses or the ideal time to use the neuropod?
28:30
So the numbers, what do, what do they mean?
28:33
It, it is so funny because we live in such a data-driven world right now.
28:38
And I come from a world of science.
28:40
I have five degrees, and I get sometimes a little bit frustrated because we're so caught up on the numbers without truly understanding what the numbers mean.
28:52
And we see this in sport all the time.
28:54
And everyone's measuring HRV.
28:58
Everyone's got a Whoop or an Oura Ring, right? But no one really understands what it means.
33:01
I'd like to understand why my HRV is low when I feel positively connected to my heart, which is during meditation." And I know that's a really specific question, but I guess a, a broader question beyond it is should HRV, kind of like I, I was asking about the sympathetic and parasympathetic nervous system, should it, should it kind of intuitively relate to how you're feeling in your body at that moment, or can it sometimes seem to be a mismatch?
45:41
Mm
45:42
... place, and I am very much across the fact that I, you know, the nervous system's the last frontier in medicine and performance, and I think just, you know, in current times are where people are actually starting to take vagus nerve stimulation and the impact on all the other systems, particularly hormones, um, seriously.
46:06
I know from a woman's health perspective and from case studies and people that I've worked with myself personally, definitely that nervous system regulation in terms of hormone regulation is, like, hugely impactful.
46:22
And myself and other people have been directed down the path of very different, um, medicines and therapies, and the vagus nerve stimulation was able to, you know, decrease and remove symptoms in pretty much all those cases.
46:40
So I'm not saying it's a one stop to everything.
46:43
Um, there's definitely people that I work with that, um, we are still having to support them with hormone replacement and things like that in order to bolster that.
46:53
But I think, you know, when you really consider the nervous system is in control of all of it, so if your nervous system's regulated, all those other functions are gonna be so much better, and whether that's just 1%, 2%, so whether as a male your testosterone levels are improved, or you're getting more growth hormone 'cause your sleep quality's better, as a female with your progesterone, you're getting a little bit more progesterone, estrogens available to you when you need it better, all those kind of things.
48:34
I'm pretty sure there's quite a lot of research on vagal nerve stimulation and things like IBS from memory or things like that.
