Journal Club with Dr. Peter Attia | Effects of Light & Dark on Mental Health & Treatments for Cancer
In this journal club episode, my guest is Dr. Peter Attia, M.D., a Stanford and Johns Hopkins-trained physician focusing on healthspan and lifespan and the host of The Drive podcast.
We each present a peer-reviewed scientific paper chosen because it contains novel, interesting, and actionable data. First, we discuss a paper on how bright light exposure at sunrise and throughout the day and dark exposure at night independently improve mental health and can offset some of the major symptoms of mental health disorders such as depression and anxiety. Then, we discuss an article that explores a novel class of immunotherapy treatments to combat cancer. We also discuss some of the new data on low-calorie sweeteners and if they are safe. This episode should be of interest to listeners curious about maximizing their vitality and longevity and to anyone seeking science-supported ways to improve mental health and lifespan.

this is free. 20 years ago you wouldnt find this kind of education so easily. thanks
For real. So grateful
true but what I am finding now is the overwhelming amount of information leading to paralysis by analysis
@@adamek9750 Haha. I pick and chose these days instead of listening to them all.
@@adamek9750stop coming at me like that!! 😅😅😅 …
{Indeed, in the creation of the heavens and the earth and the alternation of the night and the day are signs for the wise. Who remember God while standing or sitting or on their sides and give thought to the creation of the heavens and the earth, saying: "Our Lord, You did not create this aimlessly; exalted are You; then protect us from the punishment of the Fire. Our Lord, indeed whoever You admit to the Fire, You have disgraced them, and there are no helpers for the wrongdoers. Our Lord, indeed we have heard a caller calling to faith, 'Believe in your Lord,' and we have believed. Our Lord, so forgive us our sins and remove from us our misdeeds and cause us to die with the righteous. Our Lord, grant us what You promised us through Your messengers and do not disgrace us on the Day of Resurrection. Indeed, You do not fail in promise." And their Lord responded to them, "Never will I allow to be lost the work of any worker among you, whether male or female; you are of one another. So those who emigrated or were evicted from their homes or were harmed in My cause or fought or were killed, I will surely remove from them their misdeeds, and I will surely admit them to gardens beneath which rivers flow as reward from God, and God has with Him the best reward."}
After decades of feeling groggy and like I have a very low level hangover almost daily, sleeping in 11-12 hours a day, brain fog, literally unable to formulate sentences properly. You have changed my life Andrew, I spent the majority of my twenties gaming 7-14 hours a day and rarely viewing ANY sunlight in a small dark bedroom 90% of my time, and vitamin D deficient. I felt suicidal and depressed most of that time and struggled with daily tasks as felt tired a lot. I thought I had chronic fatigue syndrome but was completely oblivious to the effect light has on the human body. I get by on around 7-9 hours of sleep daily and feel OK. I am almost crying writing this because my life was a meaningless mess up until age 30 or so. I really cannot thank you enough and will continue to support your work. You really have benefitted me in incredible ways.
Separately, you two are amazing. Together, this is pure gold. Please keep doing journal club! 🙏
Agreed
You’ve got that right. I feel that between Peter Attia and Andrew Herman, all of my health needs have either been answered, or will be in an episode coming soon
After over 10 years on self-improvement, the number one thing I’ve come to understand is that I am most disciplined, strong, fulfilled, loving, and present, when everything I do is an expression of a healthy self worth. I have nothing to prove, not even to myself. I realise that I am worthy of my own honour and respect, and that of others. If I’m not treating myself in the best way to honour the highest side of myself, or I’m allowing others to treat me badly, then something is off. I honour the passions and purposes I feel called toward by diligently working toward them. I work on myself everyday and reap the rewards, not because I need to so I can feel good about myself, but because guess what, I’m worth it. I deserve to be happy, healthy and prosperous, so do you.
I love this. I want to read it daily ❤
Yes! Don’t forget to practice semen retention as well
Bot comment
@@vincebuzzurro9713 you mean celibacy?
Profoundly simple. Can you recall a few pivotal "moments" (readings, interactions, experiences) that cemented this idea for you?
Drs. Thank you. My brother died of melanoma 30+ years ago that first began in his eye, then 5 years later occurred on his skin and metastasised. I was watching a Mayo Clinic documentary and his eye cancer would now have localized treatment with a radiation eye patch, with a high degree of successful treatment. Also, I'd like to add that my brother did donate his eye to scientific research at Mayo Clinic, and likely it was used to help develop these new therapies. For the listeners to this podcast. Please, please, please consider giving your body or some of it to science. You never know how many people you can help save.
Sorry for your loss. Now immunotherapy is used to treat metastatic melanoma as in president Carter who was cured by this new costly treatment.
💔🕊️🕊️
Thank you for your brothers’ contribution to humanity and for his and your family’s way of making meaning out of an extremely painful loss. ❤ I appreciate it!
@@dr.samierasadoonalhassani2669 I could be wrong but I think they’re doing something similar with hearing loss.
Very sorry for loss. I always find myself pondering as to how much influence the mind has over our physicality. Would you mind if I asked whether or not your brother generally was a happy guy ? Conditions such as fibromyalgia don't appear to have a definable cause so again it makes me wonder if people claiming to suffer from it have just worked themselves into a critical state of mental health. BTW, I'm exploring psychology as a career. Thank you for reading this.
I'm In the middle of reading your book dr.Attia .Chris Williamson said you can tell a person by their top 5 podcast, I got a twofer today 😊😊had breast cancer for my 50th birthday 🎂 double mastectomy.I will be 65 this march n have been traveling the 🌎 solo since 2020 , I believe finding both your podcasts has been the greatest influence on me , thank you both so much 😊😊
Wow I love your positive attitude! very inspiring☀️
👍✌🏻🤗
Highly supportive of Journal Club, please continue this series. I've always been wondering when you'd show HOW you and colleagues read a paper.
I have a young son recently in remission...learning that even if "cancer free", his life and physiology is now forever changed. We have learned A LOT and have even more questions, but are determined to learn and live and contribute to the fullest with what came our way as a family. The information out there is abundant and yet so much of it still isn't understood...I am no one....first responder, grunt, Mom, but I research in order to "deal", if you would. It is as you said, "sobering", especially as a parent. Just wanted to say "thank you" for having not just this conversation, but all of them. Much love and rooting for you from Corpus Christi, Texas brotha🤙🎗️
Andrew and Peter are literally the best duo ever Thank you for this podcast!
His book is amazing ! Thank you Dr Huberman and the team for bringing Dr Peter again to the episode 🙏
I wish he had not mentioned the centurions in the first part as now my dad thinks drinking and smoking is probably okay.
I love how these guys are educating each other while they educate us. They’re easy to learn from because they break things down into layman’s terms and illustrations. Ironically without giving listeners the feeling of the information having been dumbed down. Thanks Guys! You’ve both significantly improved my life! I’m so very grateful!
I was so excited to see the topics bing discussed today. I was diagnosed with Stage 3C endometrial cancer in July of this year and after genetic testing in 2019 it revealed I have Lynch Syndrome. I am being treated at MD Anderson with chemotherapy and Keytruda and my oncologist is very optimistic that Keytruda will extend my life. I’m eager to discuss the information provided in this episode with him before my next treatment. Thank you, thank you for providing such important information.
Continue to stay strong and positive! I wish you every success in your treatment.
❤ sending love and grace
The most significant thing I could ask for to impact how I wake in the morning is shades or blinds that are pitch black at night but are timed to open before sunrise 30 minutes before sunrise that will change the entire trajectory of my days
Thank you for providing the best content on KZhead!!! ❤
¡Hola Profe!Just wanted to express my deepest gratitude to You and Dr.Attia for constantly educating us. Your hard work is truly appreciated by all of us.
I just finished listening to this podcast, it was fantastic. My mom died of pancreatic cancer while she was being treated for metastatic melanoma. I heard you mention the connection and maybe a genetic factor, so now I am worried about me and my siblings. My mom was tested for Lynch syndrome and we were told she didn't have the gene. My mom got sick and was diagnosed with pancreatic cancer, they said it was early stage and she had a successful whipple surgery. During the scans they found a lump in her upper arm which they removed and found out it was melanoma so they then did a full body scan and found a tumor in her color which when biopsied found it was melanoma. She was being treated with Keytruda and every scan showed the tumor was shrinking and we were so excited it was almost gone and she felt great while doing the treatments, it seemed to up her appetite and give her more energy. Then the pancreatic cancer appeared in her liver and she died within the next month. I would like know how I can find out more about this melanoma and pancreatic cancer connection you mentioned. Thank you.
The Morning sun definitely makes a difference. I started getting up to let my animals out before 7am and I stated sleeping better after days and starting rising before 6am refreshed and ready. DR Huberman love❤ the channel. Watch you lectures for breakfast. Good knowledge to start tie day!!!
I would love to see you discuss how many people choose to go an alternative route to beating cancer, and succeed. I have just started to research other treatments and I find it fascinating. I agree with Dr Attia, these drugs are not improving quality of life, or extending life for much longer. Patients have the right to choose how to treat their bodies. Thank you for your discussions.
As a veterinary professional who does journal club weekly at work, I LOVE these sessions! In addition, I work in cardiology, especially doing echocardiograms, and my team works in low light (
2 of my fav people, thank you Andrew, God Bless Brother.
Thank you Dr Huberman for Educating Us 😊🙏
I love this format! It’s so interesting to see how Dr.’s analyze studies. You make it very understandable for us ‘Non-Doctors’ 😊
The Huberman-Attia format stimulates a formidable dopamine spike :)
Seeing two rigorous scientific minds collaborate like this is a real treat.
This is wonderful and free! Thank you Andrew and Peter for offering us this high quality discussion. Love from Paris 🇫🇷
You can buy an inexpensive headlamp that has a red-light for its first click. So handy. Never have to turn on a light in the night. I love your podcast and have listened since the beginning.
Learn so much from you two docs. Dr. Attia is my favorite guest on your podcast. Love this Journal Club.
What a fantastic episode. I’d be interested in the sunscreen podcast but please for all that is holy, invite a toxicologist and a cosmetic chemist! They are the relevant experts. Even derms don’t study toxicology effects the way a toxicologist does. It’s so important to prevent fear-mongering in this particular area right now.
As much as I love your solo lectures, I love this duo. Fantastic conversation Thanks Andie for all the effort.
Brilliant - thank you both. Thank you Dr Huberman for simplifying a number of the concepts used by Dr Attia.
Mr. Huberman love your work. I've been using the Daily Journal method With 1. 5 Gratitudes 2. Plans for the day 3. Any Fears & Resentments 4. Things to watch out for 5. Things to strive for Since the beginning of this year. I would love to know if there's an upcoming podcast video you're going to do about it or if I can find some more info on this. Thankyou very much, appreciate all your effort towards helping humanity.
Every day? :-o
One of my favorite guests
The dynamic duo. It doesn't get better than this.
Andrew it would be awesome if you could release an episode on gut health toolkit covering multiple types of gut issues like constipation, dysbiosis, diarrhea, acid reflex etc
I think there already is some episode connected to a gut health, I advice you the check out early videos
@@kseniiachigibaeva7630 but that episode majorly focuses on fermented foods as a tool for enhancing gut microbiome.
I need as many journal clubs with you two as possible
Thank you both 💙
Ukraine. Pretty cold days. I really appreciate sunny ones❤
Dr. Huberman, your content is actionable, fascinating and informative in many regards. As a listener, I’ve gained a myriad of tools, protocols and knowledge from listening to your podcast for some time. I’ve noticed, throughout my time listening to your podcast, you call out how the audience may correct a statement made in the comment section, a statement may be controversial or the audience may not like something you or a guest have said in a particular conversation. I understand these statements might be made for comedic relief, rebuttals of your own stance or acknowledgement of the listener. In any case, since you read all the comments, I’d take it you’ll see this one. In short, I’m asking to please consider not making these types of comments since you’re indeed the expert/one with vast knowledge on these subjects and you’re being gracious enough to share this valuable, actionable and awesome information. Either way, thank you, Dr. Huberman. I hope to converse at some point in life.
Drs. Huberman and Attia, Thank you so much for this fascinating, informative, and at times mind-blowing review of these articles. I always learn something from the podcast, and these journal clubs take that to another level. As a new Ph.D. student (in my "golden years" no less), I really appreciate you both for explaining how to read scholarly and research articles. Thank you for bringing scientific inquiry to the masses. Peace, Marguerite
I am so greatful for every episode you make. I rarely miss an episode and listen to you during my workouts. Thank you so much for your effort and humbleness. Stay hard 💪. God bless you!
That was incredibly interesting and enjoyable to listen to. I appreciated that the science was explained clearly for anyone to understand, without losing too much of the technical language. I had been avoiding joining a journal club thinking that I don't know enough about nutrition science to participate, but after this episode, I feel motivated to join one. I look forward to the next journal episode.
Thank you for this, always makes my day better knowing I get to listen to this today as I go about my day 😊
My older brother was just diagnosed with lung cancer, so this talk was a real eye opener concerning his prognosis. Tough but important information. Thank you.
I love the fact that Petter explains to us like we are not scientist (dont know how to read the data). Shout out to Peter. Love this
As always thank you @Andrew Huberman! 👏🏻👏🏻
Thank you both for the very in depth and lifesaving information. You guys are wonderful, real life savers. Thank you, both. Please, stay safe and well.
Love, joy and happiness to all of you here NOW!
Thank you for all the knowledge you share Dr Huberman! See you in Sydney!
Thank you for another information-rich episode to improve mental health in such simple ways. I am sensitive to light, and did naturally come to that conclusion that checking the time in the middle of the night can hamper sleep and perceived satisfaction the proceeding day than if I didn’t check the time and attempted to go back to sleep from the get-go.
What an amazing episode! Can't believe I get to watch this for free. Thank you very much
As a mental health advocate with 3 family members having schizophrenia. I thank you for this
It's wonderful how skeptical I am before starting every single podcast you make and how valuable the lesson are for me in the end. In fact the more skeptical I am before listening, the more valuable the lessons. I think this is a very profound quality to your work, and as an engineer I find that you spread a very healthy image of what is scientific approach. Thanks again 🙏🏻
Interesting episode title, look forward to it. Thanks!
Thank you both very much for this - cannot wait for the next journal club!
It would be great if you could make a full episode on autoimmune diseases. This is something interesting more and more people, especially young ones. Many thanks for your incredible work! Best from Italy!
Andrew have you done any research on EMDR? for trauma and ptsd with eye training. curious on your thoughts. great pod brother
I’d love to read a book by Huberman.
As always, extremely informative content - debunking today's myths and false info. It would be great for Huberman or Attia to release some research and podcasts on Ankylosing Spondylitis, a challenging autoimmune disease that many struggle with today.
Great content, thank you both for sharing 🙏 Much love!
1:50:45 I’d LOVE to hear more about this because both of my children have food allergies. Thank you!
When I was a child in the sixties my mom had an infrared lamp with these little goggles that she and I would lay under. She was a nurse and very into alternative health. It is interesting that there was data about this decades ago but only now is it becoming public knowledge. Thank you for the excellent discussion.
Love these discussions! I always feel like crap in winter (i work from home) and this year I've put indoor plants (meyer lemon) with light and a timer that comes on early in the morning. My workload hasn't changed but I'm feeling sleepy a lot earlier than usual. I don't know if that's good or bad. My sleep has been consistent and I always feel refreshed when I wake up. All it did it shifted my sleep. I just wake up a lot earlier, always getting 6-7hrs of sleep. If I get any more sleep, over 8hrs I always have a headache.
Really like the new formate with the data show on screen as-well
Can we get a 10-15 minute highlights version that my wife may actually listen to because she needs to hear this stuff!
I have been applying this tips to sleep and they work. Very grateful to have found this information.
Completely enjoyed this, thank you
Love Journal Club!
Struggling with bipolar. Just started light therapy- it really works. Looking into TUO bulb now. Thank you 🙏 as always
I love these podcasts because they're always so informative and interesting. Also because I like to drool over Andrew....
As always Andrew brings powerful and informative data. Somebody create a phone with the sad light!
How I imagine their conversations are when they’re just hanging out: Exactly the same.
The irony of waking up 2am and watching this episode
Hello! Love the podcast. I was wondering if you'd ever consider doing a series on Neurobiology 101 (kind of like how MIT does those free open courses). I'm talking specifics as if this were a freshman year undergrad class on the topic. I know that's a lot of work but I think it'd be a big hit for people interested (including me!)
Love this. One tiny note for next discussion- it might be helpful to have the document pulled up on a computer as well so you can search and find specific text with CTRL + F function (ie, ‘figure 2’ discussion about 2.5 hrs in)
An episode on contrasting light and dark would be amazing - for example, the science behind darkness retreats (like the one Aaron Rodger’s recently attended)
Awesome info!, Thanks to both!
Great to be here.
Did anyone catch Dr. Huberman’s answer to Dr. Attia’s question about the efficacy of pre-dawn sunlight exposure? They went off track right off the bat and not certain they ever returned to a response.
Thanks for this amazing episode. I've learned a lot and will definitely try to get in a morning walk from now on. As a side note: when you're planning the sunscreen episode please discuss the new filters that are available outside of the US and why they are still not allowed. oxybenzone and similar ingredients are no longer used e.g. in European and Korean sunscreen and therefore the whole carcinogen discussion could be obsolete (of course there are still the oil people out there). Love the podcast, so thanks again
Great format! Love it!
the type of content youtube needs more of
Journal Club either sounds like a 1980's teen angst movie, or a club where the first rule is, don't talk about journaling.
"I say never be complete. Stop being perfect. I say let's evolve, let the chips fall where they may." Sometimes I think Tyler Durden had a better understanding of the human condition than these two smarty pants.
Man, you come up with the most creative comments 😂. Much love!
I was thinking n k that exct same thing
💀
Whatever the opposite of laughter is, is what this invoked in me. Absolute L😂
I appreciate all you do to serve. I work with Vocal Bioacoustics, Voicework specifically using resonance, Oral pharyngeal exercises and chiaroscuro ( light and dark balance) of the body to assist with breathwork and Carl Stough breathing method. He helped the 1968 Olympians for performing at high altitude and people with emphysema copd sleep apnea etc. I was wondering if you could delve deep into Bioacoustics for humans I've recently read Stanford University Cardiologist Sean Wu, MD, PhD and Utkan Demirci, PhD, an acoustic bio-engineer uses acoustics to manipulate heart cells into intricate patterns. A simple change in frequency and amplitude puts the cells in motion, guides them to a new position, and holds them in place. It went on to say...Acoustics can create a form that resembles natural cardiac tissue. With sound they can create new tissue to replace parts of damaged hearts. Acoustics can be used in reconstructing other organ tissue and blood vessels.
I just listened to this edition during this morning's cardio, and I actually went long because I was so engrossed int he topic. Great discussion. I wanted to add that I worked in R&D strategy at Bristol for 15 years, and was on both the ipilimumab and nivolumab teams (and I'm also Stanford trained -- now I'm a professor at ASU). If you ever want to engage more deeply in the R&D strategy side of portfolio decisions that Big Pharma makes, I'd be happy to help. Thanks again.
I love journal club!
My 2 fav Dr's. This is gonna be good!!
This was amazing to listen to. I just learned about tumor immunology in medical school and hearing Peter talk about it again helps reinforce the concepts even more. I hope journal club continues for a long time
Dr. Huberman is so well groomed in this video I almost can't focus. The eyebrows are threaded to a masculine perfection 🤌🏼. With short hair he looks biracial, with this hair he looks white. I love the versatility of it all. Oh..smart. He's also smart. Lol.
So excited for this new episode!
Totally agree with you on hospital psychosis. I have had a lot of stays in my 34 years. This past one, I was in for a week and a guy in my unit screamed 24/7. They did not medicate him to stop him so I was up for 7 straight days from the screams. I actually had to lie to the doctors that I was doing better than I was so they would discharge me because I was suicidal from lack of sleep. Obviously, the bright lights did not help but I brought my eye mask, ear plugs and sound machine to help. The screams were just too loud for any of my things to have any effect. I always refer to the hospital as the place you go to get help but end up insane and sleep deprived.
Umm production quality is fabulous
🌜I like the, “from our home to yours” feel of this! I had success last time I used the Zero app & newsletters from Dr. Attia & plan to download & dive in again today; although this time, I plan to use protein drinks to sustain it. Thanks very much gentlemen. 💫
Thank you Dr Huberman, we really appreciate and value all content you provide 🙏🤍 as I suffer from an autoimmune disorder myself (multiple sclerosis), I would love to hear an episode, from your own insight, on the non pharmaceutical ways to help keep the myelin and the nervous system in general, healthy and strong Thank you
I really appreciate this content from the two of you. I'm from a northern latitude and have had a difficult time getting natural light at all in the wintertime so this is a big topic for me. I've always noticed large differences from summer to winter in mood and overall body wellness and your work helps to explain it well, Andrew. I'm always looking for ways to improve my situation along these lines without moving south so I'll definitely look into Tuo and Joovvv. If you have any other suggestions for people in northern latitudes I'm all ears.
In regards to the sun exposure and risk of melanoma, I have a few questions: - we can compare two cases. Person A spends more total time with exposed skin in the sun. Maybe they get a solid tan that fades in the winter. But they rarely get burnt. Person B spends less time with exposed skin, but when they do, it more often results in sun burns. No tan Is person A less likely to get melanoma? I’d imagine not to any significant degree, but is a tan protective in any way? - What’s the safety profile of mineral vs chemical sunscreens? I did hear that even mineral sunscreens act chemically, is that true? - what does Andrew mean when he says endocrine disrupters? What is being disrupted, to what degree, what kinds of experiments show this, and is that significant? Thanks for the podcast!! Really look forward to listening in full later
Thank you
Hey Andrew Could you do one on dyslexia please? Big fan here Thanks so much
Sigh. I'm watching this and I'm sure everything they say is true but for a lot of us it's a lot harder than "drinking coffee on the balcony." I'm looking outside and it's sleeting right now. I haven't seen the sun when it's over zero degrees in weeks. We don't all live in CA is all I'm saying.
I listen to this from Peter and I feel like I understand all parlance and makes me feel special and smart 🤣👍🏻
Is there possible a future podcast about senior life? Brain functions, exercises, supplements? That would be great for my mother and for all of us in 20-30 years. Thank you for your mission! 🙏
