  [Announcer Lucas] Welcome to Sunday Science,
• 0:01
  [Announcer Lucas] where we dive into a few recent scientific articles and their
• 0:04
  [Announcer Lucas] translation into our modern lives.
• 0:06
  [Announcer Lucas] Here is your host,
• 0:07
  [Announcer Lucas] Brent W.
• 0:08
  [Announcer Lucas] Lartz,
• 0:09
  [Announcer Lucas] M.

  [Announcer Lucas] D.
• 0:10
  [Dr. Brent Laartz] All right,
• 0:11
  [Dr. Brent Laartz] thank you for attending another episode of Sunday Science,
• 0:14
  [Dr. Brent Laartz] where we are going to be talking about...
• 0:18
  [Dr. Brent Laartz] Entrainment.
• 0:19
  [Dr. Brent Laartz] So entrainment involves the use of either auditory or visual stimulation.
• 0:28
  [Dr. Brent Laartz] Indifferent.
• 0:29
  [Dr. Brent Laartz] Entrainment.
• 0:31
  [Dr. Brent Laartz] patterns.
• 0:32
  [Dr. Brent Laartz] So this involves a either a light source or something called isochronic beats,
• 0:41
  [Dr. Brent Laartz] which would be just a monaural.
• 0:45
  [Dr. Brent Laartz] auditory source or something called binaural beats which basically
• 0:49
  [Dr. Brent Laartz] creates the same thing but it has to be with headphones creating a
• 0:56
  [Dr. Brent Laartz] binaural input into the brain and by having a certain wavelength of sound or light.
• 1:08
  [Dr. Brent Laartz] then you create this entrainment.
• 1:11
  [Dr. Brent Laartz] So we know that there are different brain waves associated with
• 1:19
  [Dr. Brent Laartz] certain types of wakefulness,
• 1:21
  [Dr. Brent Laartz] concentration,
• 1:24
  [Dr. Brent Laartz] or relaxation,
• 1:26
  [Dr. Brent Laartz] or sleep.
• 1:27
  [Dr. Brent Laartz] And these are the delta waves,
• 1:30
  [Dr. Brent Laartz] theta waves,
• 1:31
  [Dr. Brent Laartz] gamma waves,
• 1:32
  [Dr. Brent Laartz] alpha waves.
• 1:32
  [Dr. Brent Laartz] Alpha waves are associated with wakefulness.
• 1:35
  [Dr. Brent Laartz] Gamma waves are associated with concentration.
• 1:37
  [Dr. Brent Laartz] concentration and wakefulness and Then the theta and delta waves are
• 1:44
  [Dr. Brent Laartz] associated with relaxation and sleep.
• 1:46
  [Dr. Brent Laartz] So here's we're going to discuss] just a few different studies
• 1:49
  [Dr. Brent Laartz] showing different effects on sleep and cognition.
• 2:00
  [Dr. Brent Laartz] With the 40 hertz or gamma wave entrainment,
• 2:04
  [Dr. Brent Laartz] so I'll show you a little bit of some examples of entrainment.
• 2:09
  [Dr. Brent Laartz] I haven't used this specifically yet,
• 2:13
  [Dr. Brent Laartz] but this is a light bulb that and you're not going to be able to
• 2:17
  [Dr. Brent Laartz] possibly completely appreciate the different wave length or the the
• 2:27
  [Dr. Brent Laartz] stimulation of this because you're probably seeing this on either 60
• 2:32
  [Dr. Brent Laartz] hertz or 120 hertz display.
• 2:36
  [Dr. Brent Laartz] And if you're listening to this just on auditory.
• 2:38
  [Dr. Brent Laartz] I have a light bulb.
• 2:39
  [Dr. Brent Laartz] I'm switching it on.
• 2:41
  [Dr. Brent Laartz] And on my end,
• 2:43
  [Dr. Brent Laartz] this blinks approximately once every...
• 2:48
  [Dr. Brent Laartz] 1 40th of a second so 40 times per second so 40 hertz you're going
• 2:53
  [Dr. Brent Laartz] to just notice some blinking on the screen but it is not going to be
• 2:56
  [Dr. Brent Laartz] possibly at 40 hertz it may be a difference between your 60 hertz and not.
• 3:00
  [Dr. Brent Laartz] So this is just a light bulb that does it.
• 3:03
  [Dr. Brent Laartz] There are various products out there that in can do the same thing.
• 3:09
  [Dr. Brent Laartz] This is at 40 hertz,
• 3:10
  [Dr. Brent Laartz] so we'll start with that 40 hertz and look up multiple studies.
• 3:15
  [Dr. Brent Laartz] There are multiple studies associated with Alzheimer's disease and cognition.
• 3:19
  [Dr. Brent Laartz] with this 40 hertz either light source or with a binaural beat in the headphones.
• 3:27
  [Dr. Brent Laartz] I'm going to show you for...
• 3:34
  [Dr. Brent Laartz] some example of this is a 5.
• 3:37
  [Dr. Brent Laartz] 5 hertz isochronic tone,
• 3:39
  [Dr. Brent Laartz] so it doesn't need to be in the Headphones.
• 3:47
  [Dr. Brent Laartz] And this also has metal crystal bowls and rain associated with it.
• 3:51
  [Dr. Brent Laartz] But it shows the 5.
• 3:54
  [Dr. Brent Laartz] 5 hertz.
• 3:55
  [Dr. Brent Laartz] This is associated with better sleep.
• 3:57
  [Dr. Brent Laartz] I'll show you some— let's see,
• 4:00
  [Dr. Brent Laartz] that's binaural.
• 4:01
  [Dr. Brent Laartz] You can search this.
• 4:02
  [Dr. Brent Laartz] I use YouTube Music.
• 4:03
  [Dr. Brent Laartz] You can search this.
• 4:05
  [Dr. Brent Laartz] Looking for gamma wave.
• 4:08
  [Dr. Brent Laartz] This is—uh,
• 4:09
  [Dr. Brent Laartz] let's see.
• 4:09
  [Dr. Brent Laartz] This is Theta waves.
• 4:13
  [Dr. Brent Laartz] So let me look for gamma wave and I'm going to look for isochronic.
• 4:18
  [Dr. Brent Laartz] Beats.
• 4:19
  [Dr. Brent Laartz] So isochronic tones.
• 4:22
  [Dr. Brent Laartz] Would be ones that you would not need.
• 4:29
  [Dr. Brent Laartz] And I'm not sure if you can hear that,
• 4:30
  [Dr. Brent Laartz] but there's obviously some.
• 4:38
  [Dr. Brent Laartz] Birds in the background.
• 4:39
  [Dr. Brent Laartz] And if you listen really closely,
• 4:41
  [Dr. Brent Laartz] you can hear.
• 4:43
  [Dr. Brent Laartz] A beat.
• 4:53
  [Dr. Brent Laartz] and that is approximately 40 hertz gamma waves isochronic.
• 5:00
  [Dr. Brent Laartz] Okay,
• 5:00
  [Dr. Brent Laartz] so let's see if I can find another one.
• 5:05
  [Dr. Brent Laartz] This is binaural.
• 5:09
  [Dr. Brent Laartz] Let's see what this one has.
• 5:14
  [Dr. Brent Laartz] Yeah.
• 5:30
  [Dr. Brent Laartz] This doesn't have it.
• 5:42
  [Dr. Brent Laartz] This is 45 hertz binaural.
• 5:47
  [Dr. Brent Laartz] Pure gamma waves.
• 5:48
  [Dr. Brent Laartz] Let's see if this has a better.
• 5:50
  [Dr. Brent Laartz] Here we go.
• 5:51
  [Dr. Brent Laartz] This is better.
• 5:52
  [Dr. Brent Laartz] This doesn't have the added music to it.
• 5:57
  [Dr. Brent Laartz] This is basically a beat 1/40 of a second.
• 6:01
  [Dr. Brent Laartz] And 40 times per second.
• 6:04
  [Dr. Brent Laartz] This is associated with some of the studies are using 10 minutes or
• 6:09
  [Dr. Brent Laartz] 20 minutes or 30 minutes of listening to this every day.
• 6:13
  [Dr. Brent Laartz] Potentially this can increase concentration also while you're
• 6:18
  [Dr. Brent Laartz] studying and learning.
• 6:21
  [Dr. Brent Laartz] And I'll show you just a quick show of.
• 6:24
  [Dr. Brent Laartz] This study,
• 6:25
  [Dr. Brent Laartz] which was all right,
• 6:27
  [Dr. Brent Laartz] so this study,
• 6:29
  [Dr. Brent Laartz] which is using binaural beats,
• 6:31
  [Dr. Brent Laartz] um Using...
• 6:38
  [Dr. Brent Laartz] Let's pull this up here.
• 6:46
  [Dr. Brent Laartz] There's hundreds of studies out there.
• 6:48
  [Dr. Brent Laartz] This is a study showing gamma frequency entrainment,
• 6:52
  [Dr. Brent Laartz] attenuating amyloid load,
• 6:54
  [Dr. Brent Laartz] and it modified the microglia.
• 6:56
  [Dr. Brent Laartz] This,
• 6:57
  [Dr. Brent Laartz] these patients.
• 7:02
  [Dr. Brent Laartz] We're exposed to the 40 Hertz.
• 7:11
  [Dr. Brent Laartz] Binaural beats.
• 7:17
  [Dr. Brent Laartz] Let's see.
• 7:18
  [Dr. Brent Laartz] Let's get this.
• 7:19
  [Dr. Brent Laartz] This is attenuating.
• 7:57
  [Dr. Brent Laartz] Game of Stimulation showing improved sleep in Alzheimer's disease.
• 8:01
  [Dr. Brent Laartz] They did continuous actigraphy recordings.
• 8:05
  [Dr. Brent Laartz] So this is basically using...
• 8:09
  [Dr. Brent Laartz] Studies of their sleep there was a study in 2025 by Chan which showed that,
• 8:15
  [Dr. Brent Laartz] overall,
• 8:16
  [Dr. Brent Laartz] putting a 40 hertz binaural beat into place in Alzheimer's disease
• 8:22
  [Dr. Brent Laartz] improved their Mini Mental Status Exam,
• 8:24
  [Dr. Brent Laartz] their different exams related to dementia and cognition,
• 8:30
  [Dr. Brent Laartz] the CDR test,
• 8:31
  [Dr. Brent Laartz] the FAS test,
• 8:33
  [Dr. Brent Laartz] and the ADS Cog Test.
• 8:35
  [Dr. Brent Laartz] All of these improve with respect to Um,
• 8:40
  [Dr. Brent Laartz] after the load of all signs of these and I'll show you just another
• 8:49
  [Dr. Brent Laartz] study showing the improvement in sleep with theta entrainment.
• 9:01
  [Dr. Brent Laartz] So there's delta and theta entrainment you can do but this,
• 9:05
  [Dr. Brent Laartz] let me show you an example.
• 9:11
  [Dr. Brent Laartz] Let me share.
• 9:28
  [Dr. Brent Laartz] This,
• 9:28
  [Dr. Brent Laartz] as you can see,
• 9:29
  [Dr. Brent Laartz] I'm sharing a screenshot of.
• 9:31
  [Dr. Brent Laartz] Somatic complaints after theta entrainment.
• 9:34
  [Dr. Brent Laartz] So again,
• 9:35
  [Dr. Brent Laartz] using either binaural beats or isochronic beats.
• 9:38
  [Dr. Brent Laartz] In general,
• 9:39
  [Dr. Brent Laartz] sleep is not using light source.
• 9:43
  [Dr. Brent Laartz] But this,
• 9:44
  [Dr. Brent Laartz] before bedtime,
• 9:45
  [Dr. Brent Laartz] showed an improvement in somatic complaints in patients given theta
• 9:54
  [Dr. Brent Laartz] entrainment before sleep for about 20 to 30 minutes before sleep.
• 9:58
  [Dr. Brent Laartz] This study was,
• 10:02
  [Dr. Brent Laartz] let me share a different.
• 10:09
  [Dr. Brent Laartz] Screen here showing: This is showing previous.
• 10:23
  [Dr. Brent Laartz] Awakening quality.
• 10:25
  [Dr. Brent Laartz] So the quality of wakefulness after you after you wake up,
• 10:30
  [Dr. Brent Laartz] and this is subjective,
• 10:31
  [Dr. Brent Laartz] but these patients and these study subjects who were sports-related
• 10:36
  [Dr. Brent Laartz] subjects in a university,
• 10:39
  [Dr. Brent Laartz] they had better awakening quality.
• 10:42
  [Dr. Brent Laartz] They also,
• 10:43
  [Dr. Brent Laartz] okay,
• 10:44
  [Dr. Brent Laartz] so we also had another area here where they,
• 10:54
  [Dr. Brent Laartz] the subjective sleep quality.
• 10:57
  [Dr. Brent Laartz] Market improvement in sleep quality.
• 10:59
  [Dr. Brent Laartz] So,
• 11:00
  [Dr. Brent Laartz] from a score of 10 up to 25.
• 11:03
  [Dr. Brent Laartz] So you can see exactly what has happened here.
• 11:08
  [Dr. Brent Laartz] All right,
• 11:10
  [Dr. Brent Laartz] so.
• 11:11
  [Dr. Brent Laartz] Hopefully,
• 11:11
  [Dr. Brent Laartz] you were able to see that on the screen.
• 11:15
  [Dr. Brent Laartz] This was from,
• 11:16
  [Dr. Brent Laartz] I'll share the exact.
• 11:19
  [Dr. Brent Laartz] Study that that came from.
• 11:24
  [Dr. Brent Laartz] This was Brainwave Entrainment for Better Sleep and Post-Sleep State
• 11:28
  [Dr. Brent Laartz] of Young Elite Soccer Players,
• 11:30
  [Dr. Brent Laartz] a pilot study.
• 11:32
  [Dr. Brent Laartz] So you can see this was in the journal.
• 11:39
  [Dr. Brent Laartz] European Journal of Sports Science.
• 11:41
  [Dr. Brent Laartz] They were trying to assess whether there was some improvement in
• 11:45
  [Dr. Brent Laartz] their Sports ability afterwards as well.
• 11:54
  [Dr. Brent Laartz] I think they didn't necessarily show that per se,
• 11:56
  [Dr. Brent Laartz] but.
• 11:57
  [Dr. Brent Laartz] Definitely showed better sleep quality using the theta entrainment.
• 12:02
  [Dr. Brent Laartz] All right.
• 12:02
  [Dr. Brent Laartz] So,
• 12:04
  [Dr. Brent Laartz] thank you very much.
• 12:05
  [Dr. Brent Laartz] This is really just a short episode here of Sunday Science because
• 12:12
  [Dr. Brent Laartz] I'm getting into this uh before sleep using a theta entrainment of
• 12:17
  [Dr. Brent Laartz] either light or or an oral source that's a Ural source of theta
• 12:25
  [Dr. Brent Laartz] entrainment and maybe delta entrainment.
• 12:27
  [Dr. Brent Laartz] There are different studies.
• 12:29
  [Dr. Brent Laartz] Fascinating.
• 12:31
  [Dr. Brent Laartz] Area of research that we can delve into more.
• 12:37
  [Dr. Brent Laartz] As we go along here.
• 12:38
  [Dr. Brent Laartz] I appreciate you visiting us.
• 12:41
  [Dr. Brent Laartz] And.
• 12:42
  [Dr. Brent Laartz] We will be.
• 12:45
  [Dr. Brent Laartz] Showing a lot more.
• 12:47
  [Dr. Brent Laartz] Evidence-based medicine.
• 12:49
  [Dr. Brent Laartz] Showing how you can improve your sleep.
• 12:52
  [Dr. Brent Laartz] Improve your diet.
• 12:54
  [Dr. Brent Laartz] Improve your exercise quality.
• 12:56
  [Dr. Brent Laartz] Uh,
• 12:57
  [Dr. Brent Laartz] and.
• 12:58
  [Dr. Brent Laartz] Your creativity and increasing longevity.
