0:02
I get asked a lot about the safety or
0:05
lack thereof of a Bluetooth headphones
0:08
um you work on the brain you're a brain
0:10
surgeon that's valuable real estate in
0:12
there and you understand about
0:14
electromagnetic fields and sure um any
0:17
discussion about emfs immediately puts
0:18
us in the category of uh oh like get
0:20
their tin foil hats and yet I've been
0:23
researching emfs for a future episode of
0:25
the podcast sure and emfs are
0:28
a real thing that's not a valuable
0:31
statement everything's a real thing at
0:32
some level even an idea but there does
0:36
seem to be some evidence that
0:38
electromagnetic fields of sufficient
0:41
strength can alter the function of maybe
0:44
the health of but the function of neural
0:45
tissue given that neural tissue is
0:47
electrically signaling among itself so
0:51
um I'll just ask this in a very
0:52
straightforward way do you use Bluetooth
0:53
headphones or wired headphones yeah
0:55
Bluetooth and you're not worried about
0:57
any kind of EMF Fields across the skull
1:00
no I mean I I think the energy levels
1:02
involved are so tiny that uh you know
1:07
ionizing radiation aside we're way out
1:09
of the realm of ionizing radiation that
1:11
people would worry about
1:13
um you know tumor causing EMF Fields
1:18
um even just the electromagnetic field
1:21
itself uh as is very well described in a
1:26
frequency range the power levels are
1:29
tiny uh in these devices and so you know
1:32
we are Awash in these signals whether
1:34
you use Bluetooth headphones or not for
1:37
that matter you're you're getting
1:38
bombarded with ionizing radiation in a
1:40
very tiny amount no matter where you
1:42
live on earth unless you live under huge
1:48
um it's unavoidable and so I think you
1:52
just have to trust that your body has
1:55
the DNA repair mechanisms that it needs
1:57
to deal with the constant bath of
1:59
ionizing radiation that you're in as a
2:02
result of being in the universe and
2:04
exposed to cosmic rays
2:06
in terms of electromagnetic fields there
2:12
you know the energy levels are way way
2:15
out of the range where I would be
2:16
worried about this what about heat
2:19
um you know I don't use the earbuds any
2:22
longer for a couple of reasons once as
2:24
you know I take a lot of supplements and
2:26
I reach into my left pocket once and
2:27
swallowed a handful of supplements that
2:29
included a Bluetooth a airpod pro
2:33
um I knew it I swallowed it the moment
2:36
gulped it down by the way folks please
2:38
don't do this it was not a good idea it
2:40
was it wasn't an idea it was a mistake
2:42
and but I could see it on my phone as
2:44
registering there never saw it again so
2:45
I'm assuming it's no longer in my body
2:49
anyway there's a bad joke there to be
2:52
um but in any event I I tend to lose
2:54
them or misplace them so that's the main
2:56
reason but I did notice when I used them
2:59
that there is some heat generated there
3:02
um I also am not convinced that plugging
3:04
your ears all day long is there's some
3:06
ventilation through the through the
3:08
sinus systems that include the ears so
3:10
it sounds to me like you're not
3:11
concerned about the use of of
3:15
um what about heat near the brain I mean
3:17
there's the the cochlea the auditory
3:20
mechanisms that sit pretty close to the
3:23
um heat and neural tissue are not
3:27
um I'd much rather get my brain cold
3:30
um in terms of keeping the cells healthy
3:34
um should we be thinking about the heat
3:36
effects of some of these devices or
3:38
other things is there anything we're
3:40
overlooking well think about it this way
3:42
the uh I use cars as an analogy a lot
3:46
and you know mostly internal combustion
3:48
engine cards so these analogies are
3:50
going to start to be foreign and useless
3:53
for another generation of people that
3:55
grow up in the area of electric cars but
3:57
using cars as a as a platform to talk
4:02
fluid cooling systems your body has a
4:05
massive distributed fluid cooling system
4:08
similar to a car's radiator
4:10
uh you're pumping blood all around your
4:12
body all the time at a very strictly
4:14
controlled temperature
4:16
that blood carries it's mostly water so
4:19
it carries a huge amount of the heat
4:22
away or cold away from any area of the
4:26
body that's focused heating or focused
4:30
cooling so you could put an ice cube on
4:31
your skin until it completely melts away
4:34
and the blood is going to bring heat
4:35
back to that area you can put you can
4:37
stand in the sun under
4:42
heating Rays from the Sun itself that
4:44
contain UV radiation that's that's
4:47
definitely damaging your DNA if you're
4:50
looking for things to be afraid of the
4:53
now you're talking to the guy that tells
4:54
everybody he got sunlight in their eyes
4:56
every morning but I don't want people to
4:57
get burned or give themselves skin
4:59
cancer I encourage people to protect
5:01
their skin accordingly and and different
5:03
individuals require different levels of
5:05
protection from the Sun sure some people
5:06
do very well in a lot of sunshine never
5:09
get basal cell or anything like that
5:11
some people and it's not just people
5:13
with very fair skin a minimum of sun
5:16
exposure can cause some issues and here
5:19
I'm talking about sun exposure to the
5:20
skin of course staring at the sun is a
5:23
bad idea I never recommend thinking
5:24
about the sun just as a heater uh you
5:27
know for for a moment to compare it with
5:29
Bluetooth headphones your body is very
5:33
capable of carrying that heat away and
5:35
dissipating it you know via sweat
5:38
or you know temperature Equalization so
5:42
any heat that's locally generated in the
5:45
you know one there's a pretty large bony
5:47
barrier there but two there's a ton of
5:48
blood flow in the scalp and in the head
5:50
in general and definitely in the brain
5:52
that's going to regulate that
5:53
temperature so I think certainly there
5:57
can be a tiny temperature variation but
5:59
I doubt very seriously that it's enough
6:01
to cause a significant problem
