I have suffered from sleep paralysis for more than 20 years. I sort of understand how people get it, but not about the dreams that I have, which many people from around the world also have which are exactly the same. The entity at the bottom of the bed, the footsteps outside my bedroom and the figure outside my house, which I have no idea if I get up and look out my window or if it is part of the dream.

So true about the night owls. I´ve struggled getting up early and going to bed early for almost my entire life. No matter how hard I tried, I just couldn´t force myself into a more typical schedule. 3 am to 11 am or so would be my preferred sleep schedule. I had given up hope of ever being able to consistently get up early and feel refreshed throughout the day. Until I started getting that morning light. A week in and there´s no going back for me. It really is night and day difference for me, no pun intended.

[@monicapower6049]

That is awesome!! Well done!! What are your wake and sleep times now?

[@FeelingShred]

Now that I've been waking up early, another unexpected problem started to happen. There's this time in the afternoon my body asks for a nap around 2 or 3PM, okay no big deal. The problem is: my "naps" end up being 5 or 6 hours. Is there a way for me to limit nap time somehow? That's when my entire sleep schedule goes to the trash bin and the cycle starts from zero

[@FeelingShred]

And this has been happening for years now, I was never able to sleep at night as well as my afternoon sleep. It's the perfect sleep but it happens at the worst possible hour of the day.

It's similar to napping but is conscious relaxation. 01:03:54 🧘 Meditation, including yoga nidra, and standard meditation practices can activate the parasympathetic nervous system, promoting calmness and aiding sleep. 01:04:52 💤 Meditation and yoga nidra can accelerate the transition to sleep, helping individuals relax and turn off racing thoughts. 01:05:22 🌌 Certain forms of hypnosis for sleep can also be effective in inducing deep relaxation for better sleep. 01:06:21 🕰️ Practicing relaxation techniques like meditation and yoga nidra throughout the day can help train your nervous system to switch from alertness to relaxation. 01:07:15 ⚖️ It's easier to stay awake intentionally than to force yourself to fall asleep. When struggling to sleep, focus on the body, not just the mind. 01:09:38 🌞 Practicing non-sleep deep rest (NSDR), like meditation and yoga nidra, can reset the ability to be awake and attend to tasks after emerging from NSDR. 01:10:30 🧠 NSDR can reset neuromodulators in the brain, improving deliberate engagement in tasks and outcomes (DPOs). 01:11:57 💊 Many compounds and supplements can affect circadian rhythms and sleep, so caution is needed when considering their use. 01:14:24 🚫 Cocaine and amphetamines are not recommended for sleep enhancement due to their addictive potential and negative side effects. 01:15:18 💡 Magnesium threonate and theanine are supplements that may help improve sleep by increasing GABA and reducing racing thoughts. 01:18:13 ☕ Apigenin, derived from chamomile, can also promote sleep, but it's important to consider its effects on estrogen levels. 01:20:44 📝 Questions and involvement from the audience are encouraged to dive deeper into topics related to sleep, wakefulness, and neuroscience.

As a result of discovering I have one copy of the APOE4 gene I bought an Apple Watch to track my sleep- I was horrified by the VERY low results of my stage 4 sleep. After watching this podcast and applying most of the tools (including the suggested supplements) I am SO pleased to report that my average time spent in Stage 4 has increased over the past four months from an initial low of 3% to a more steady and acceptable 10%. I’m certain (given my age) this will set me up for another few years of more optimal cognitive function at least. Thank you so much Dr. Huberman for your time and knowledge!!

I'm impressed by your impeccable diction and would love to learn how you learned the craft of public speaking, since you excel at sharing complex ideas with clarity, while not compromising the content. And your speaking skills allow you to be understood by those who don't speak English as a first language, since the pronunciation is clear. Maybe something for a random video, but it's an important skill for any scientist.

[@toddalquist3391]

Well said

[@TUNEUSWellness]

This was such a great, informative episode. I took lots of notes to help incorporate this new info into my life to build a healthier lifestyle. Sharing my notes here, hope they are helpful :) Sleep resets the ability to be focused, alert and emotionally stable in the wakeful period. There are 2 forces that determines sleep. Chemical forces which are adenosine, cortisol, epinephrine and adrenaline and Melatonin. And the Circadian Force which is the clock that exists in our brains that determines when we want to be sleepy or awake. Light exposure is the key driving force to setting our circadian rhythm & driving the right chemical/hormonal forces at the right times of day. Best Waking Practices 1. Get outside upon waking (ideally within 1-2 hours of sunrise) and get light exposure to the eyes & body. (Don’t look at light if it hurts your eyes). Early in the day, your retina is not sensitive which will need a lot of photons coming from sunlight to set clock mechanisms. 2. Sunrise light intensity & color temperature (from sun being low in the sky) is ideal to set our circadian and hormonal rhythm. 3. Getting outside is ideal because the intensity of outdoor light is so much greater than indoor or screen light. (Outdoors Sunny day: 100,000 lux, Outdoors Cloudy Day: 10,000-50,000 lux and Inside Bright lights: 500 - 1,000 lux) 4. Time needed in outdoor morning light to set our body clock (Outside Sunny Day: 30-60 seconds and Outside Cloudy Day: ~5 minutes) 5. Important to be outside, viewing sunlight through a window will take 50x as long for your brain to get the necessary light information. 6. We want blue light during day, don’t wear blue light blocking glasses during the day. Best Evening Practices 1. Get outside to see the sunset. Sun is at low solar angle and close to the horizon, drives melanopsin which signals the circadian clock that it’s the end of the day 2. Use night mode screen on your device screens (my note: F.lux program for computer) 3. Dim lights, using warmer color temperature. (my note: Philips hue) 4. Candles / Fireplace wont causing wakefulness signals (Don’t burn down house) 5. The cells in our eyes that signals the central clock resides mostly in the bottom half of our retina which means it’s viewing our upper visual field. To avoid improper activation of neurons, place light low in your physical environment, on desktops or floor. 6. It is absolutely crucial to avoid light exposure between 11pm and 4am. It will disrupt many important physiological processes that help us rest and repair. Provide consistent powerful light anchors during the day and avoiding light at night, you get a tremendous number of positive effects on your wellbeing. Control your sleep environment 1. Get the right light exposure at the right times 2. Have dim, low lights at night 3. Get the proper sleep surface & pillow for spine alignment (my note: organic natural material) 4. Set the right sleep temperature (my note: ~65F (18.3 degrees Celsius) ) 5. Set your exercise timing to a regular period throughout the week, ideally in the morning. Non-Sleep Deep Rest are practices that activate cells in your body that promotes the parasympathetic or calming system. 1. Yoga Nidra/Yoga Sleep (Dr. Huberman's favorite) 2. Meditation 3. Hypnosis Recommended Sleep Drugs & Supplements 1. Magnesium - Huberman takes 300-400 mg, 30 mins before sleep (Consult doctor about appropriate dosing for you.) 2. Theanine - Take 100-200mg of theanine 30-60 minutes before bed 3. Apigenin (Can lower estrogen, women use caution) - Taking 50mg of apigenin can support the creation of sleepiness and you help fall asleep faster.

[@janicep1446]

This podcast was life-changing for me, and I mean it. I have been struggling to fix my sleep cycle for years now and I never understood why it was so difficult for me. I tried so hard to sleep and wake up early but I could never be consistent with it. I never felt well rested when I work up early and always thought that maybe I am just a night owl. After listening to this podcast I realized I had incorporated several bad habits into my life like not getting sunlight when I wake up and exposing myself to bright screens and working late in the night, because I would start my day late and inevitably end up staying up late. I do not have many windows in my room and my curtains are always closed which now makes so much sense why I never felt fully awake. I read countless blogs and watched YT videos hoping I'd find a way to fix this bad habit because I could sense that this was starting to affect my lifestyle, work, and even relationships because I'd never wake up on time and make it any place on time in the mornings. I struggled with this for years, and when you explained this, I could connect all the dots and it made me tear up Mr. Andrew, I am so so thankful to you for sharing this. I never comment on YT videos but this right here was life-changing for me and I wanted to let you know that you are a blessing in disguise for people like me. Very grateful! When you said 'it's difficult to change your mind with your mind', it hit me so hard. I had been trying to force myself to change just mentally intending to do it but didn't know how to go about it. But with your advice, I will begin to make positive changes, and live a happy, conscious, and healthy life. Please continue to share your knowledge! Thank you so much! ❤️

I want to testify that Dr. Andrew's podcast made me finally understand what happened to me. A year and a half ago I moved to another apartment and, a few days later, without having done anything special, I found myself waking up and sleeping earlier. Until then, I thought I was an owl: I slept late and woke up late. I only woke up early in extreme need and it was terrible. It turns out that now everything makes sense: in the new apartment, I see the morning sun and sunset every day. I could never imagine that the sun changed my life!
