I find 40Hz great for sleep. After a long battle with acute insomnia I read about the 40Hz therapy side effect of improved sleep and gave it a try. Its now 4 years on. Can't tell you how many night's sleep it has helped saved. Initially, I used 40Hz during waking hours. But then one night when I couldn't sleep at all I thought, what the heck, I may as well spend some time getting the brain cleansing from 40Hz. Wouldn't you know it knocked me right out. After a few minutes I was right back to sleep. I now use 40Hz primarily in the middle of the night as required when I wake up but can't get back to sleep. After 20 to 30min of sleepless I hit the 40Hz. I use an intense exposure: over ear headphones for deep bass response and loud at maybe 75 to 80 Db. I use a UA-cam post which I think has a particularly clear low fundamental tone. A hole is cut in a foam pillow to accommodate the headphones. 40Hz lights are the long string of little LEDs strung out in a circular array which I put right in my face on the end of an adjustable lamp. The many small lights make pretty patterns and sometimes you can imagine seeing faces and animals which makes it a little more dream-like. I also use blue blocker sunglasses to cut down on ultraviolet which can stimulate wakefulness. But basically the research says the more intense the stimulation the greater the brain response so that is what I go for. Majority of the time the 40Hz puts me back to sleep in anywhere from 5 to 20min. Sometimes if I feel closer to sleep I will put on 40Hz sound only at a lower volume and that works. Sometimes I will go a full hour on the 40Hz in the middle of the night but then turn it off and fall asleep soon afterwards. I treat the longer sessions like a meditation and try to give over my attention to the rhythm of the light and sound plus some 40Hz vibration from the over ear headphones that runs through the body and provides a third sensory input. By meditating on the 4OHz vibration I figure it gives the cognitive parts of my brain a chance to also engage with the 40Hz frequency. The times when I do 40Hz in this manner and cannot get back to sleep are extremely rare like maybe twice a year. And then 40hz will work the next night. Fortunately, I'm semi-retired and can sleep in so often I get those special extra hours of sleep between 6 and 9am. So a night's sleep might run: 12am fall asleep; 4am wake up and not back to sleep in 1/2 hour; 4:30am 1hr 40Hz; 5:30am back to sleep; 9am wake up again for 7.5 total hours of sleep. In the bad old days I would wake up at 4am and not get back to sleep at all. PARADOX So, assuming the 40Hz therapy is affecting my sleep . . . there is a paradox here: 40Hz is a brain wave frequency associated with high alertness. So how is that my brain can fall asleep to a very loud 40hz drone still ringing in my ears? Science should investigate this. But I have a hypotheses. Brain plasticity suggests the brain can learn and adapt and sometimes take what it needs in a given situation. I think the brain cleansing is key. Assume some residual molecular debris may be lingering in the brain tissue and interfering with normal sleep chemistry. The 40Hz brain cleansing comes to the rescue and clears out troublesome debris at which point natural sleep chemistry kicks in and the brain then ignores the 40Hz stimulation because it is no longer needed. Worth noting I also observe many other standard points of good sleep hygiene and take sleep supplements like melatonin, tryptophan, magnesium and chamomile. But I was taking these before the 40Hz and there was a definite improvement after starting the 40Hz. It's like the 40Hz is the thing that tips the balance and sends my brain back to dreamland.
Dr. Misha Kogan, thanks for your video! I'm been educating myself about red light therapy. This seems to be different. You speak of Herz of light, but I've been reading about Nanometers of red light or infrared light. I thought Herz was a measurement of sound, not light? And the red light panels I've been learning about are in the 620 - 830 range of red and infared light. Can you clarify to reduce my confusion? Thank you!
Yes this is indeed different there are red lights, infrared lights etc, some indeed have been shown to have some benefit. Here we are NOT taking about different nano meters we are taking about blinking regular light. Blinking occurs at very high frequency (40 times/second) so it is hard to see blinking but that's what is therapeutic. And thank you for this great question!
This therapy is very interesting. Has anyone considered the light/sound therapy for other pathologies of the brain, i.e., Parkinson's Disease, stroke, etc.?
Yes but I have not see much evidence. I think it likely will help any brain dysfunction but the reason we only talk about Alzheimer's (AD) is because this specific frequency is lacking from brain waves of patients with AD. I have recently tried to find out if the same is try with Parkinson's and was not able to find any answer.
Thanks Dr Misha - this a interesting field that is developing and great video. Have you looked into the impact of PEMF at 40 Hz? Looking through the litrature, I note that colour light may have an impact - in particular green and blue. Is this something you have looked at?
So we don't know, that's the answer. It looks like we should be studying this. It does not appear that anyone looked into if 40Hz frequency is missing from kids with learning difficulties.
Thank you for the information Dr.Kogan. Is this light therapy would be beneficial for multiple sclerosis? Or be dangerous by making the mitochondria more active to self attack the nerves? Thank you in advance
Unfortunately we do not have data to answer your excellent question. I doubt there will be any damage but to my knowledge 40Hz brain wave is missing only in brains of patients with AD not with MS or other neurodegenerative diseases, so in theory there should not be much efficacy I'm afraid.
Im apoe 3/4 and doing what i can to keep all brain matter healthy for ever. I do have a 40hz bulb and the audio with earplugs. (Need to intermittent fast and challenge my brain.) Thank you for this information. I am hoping the nir bulb (1200nm?) against forehead that was tested and had results will be for purchase soon.
Why do you need to buy ipad ? Do new phones work too? What's the difference? Why is this not being used over been hearing this for years why isn't It more popular
Yes many new phones it will work with! When we started the clinical trial that was recently published we had to use Ipads because back in 2018 iphones could not be used, now you can just find the list of all approved devices from the main website alz.life.
Yes, as soon as the study get's published in the next few months I will do short follow up video. Until that point we can't share the data since publication has already been accepted.
The study has just been accepted by a pier reviewed journal, as soon as they release the date of publication I will record another video with the update.

Thank you for this very helpful video. Is this something that children with learning difficulties can use?
Interesting question. Let me ask the founder of the App to see what he thinks. I'm not actually sure
So we don't know, that's the answer. It looks like we should be studying this. It does not appear that anyone looked into if 40Hz frequency is missing from kids with learning difficulties.
I have chemo brain, which at times drives me crazy. But I am afraid to use an app.
Are there updates on this info? I specifically want to know if there is an app for my laptop.
Why can't you use the speaker on the ipad? Is it not good enough?
Thank you for the information Dr.Kogan. Is this light therapy would be beneficial for multiple sclerosis? Or be dangerous by making the mitochondria more active to self attack the nerves? Thank you in advance

Do you know of any device to measure brainwave frequency at home?
Im apoe 3/4 and doing what i can to keep all brain matter healthy for ever. I do have a 40hz bulb and the audio with earplugs. (Need to intermittent fast and challenge my brain.) Thank you for this information. I am hoping the nir bulb (1200nm?) against forehead that was tested and had results will be for purchase soon.
Do you always have to Look at it or if it is in your peripheral vision that works as well?
does it work for depression related brain decline? also, is listening to only the audio only half as effective or not effective at all?
What’s the recommended duration for each session on the app?
1 hour. It's in the instructions.
Why do you need to buy ipad ? Do new phones work too? What's the difference? Why is this not being used over been hearing this for years why isn't It more popular
Yes many new phones it will work with! When we started the clinical trial that was recently published we had to use Ipads because back in 2018 iphones could not be used, now you can just find the list of all approved devices from the main website alz.life.
@@DrMishaKogan is it only the pro models that work?
You mention needing to use external speakers and a subwoofer with this app. Can you use quality headphones instead?
YES!!! It is actually preferred to use over ears headphones, ideally corded
Do you have the results from your internal study that you could share with us? Thanks!!
Yes, as soon as the study get's published in the next few months I will do short follow up video. Until that point we can't share the data since publication has already been accepted.
The study has just been accepted by a pier reviewed journal, as soon as they release the date of publication I will record another video with the update.
Do you have a likely date for publication of your paper?
Actually it is published! Here is the link: www.mdpi.com/2227-9032/11/14/2040
How long and often did your patience use the therapy to get results?
Minimum 3 months to see results, every day for 1 hour is best, probably 30min/day is absolute minimum to see any benefit.
Where is the link for the TED talk?
It's in the description of the video, but here is copy/paste in case somehow you don't see it: www.ted.com/talks/li_huei_tsai_could_we_treat_alzheimer_s_with_light_and_sound
