Sleep, Rewritten: Why Kids Sleep, Adults Don’t, and How to Restore the Signal Part 1
If you watch a child fall asleep, it looks effortless. Not because the child is relaxed or well behaved, but because nothing inside them is fighting the process. Sleep is not something the brain turns on. Sleep happens when nothing is left on. That distinction matters. Children fall asleep because their systems are quiet by default. Adults lie awake because their systems never fully stand down. Think of sleep like landing a plane. Kids approach the runway with clear airspace, working instruments, and a cooperative control tower. Adults are trying to land during a storm, with half the gauges flickering, while still answering emails from the cockpit. The issue is not motivation. It is interference. Biological coherence means all systems agree on three things at the same time. What time it is. What state the body is in. And what the priority should be. In children, these signals are aligned. Light exposure matches the sun. Food intake follows hunger. Movement happens outdoors. Stress resolves quickly. Sleep pressure builds naturally. Nothing has to be forced. In adults, those signals are fragmented. People wake before sunrise under artificial light. They eat late while stressed. They spend most of the day indoors. They carry unresolved cognitive load into the evening. They ask the brain to shut off while feeding it stimulation. Sleep does not fail because melatonin is low. Melatonin is low because the brain does not believe it is nighttime. Children do not need magnesium, glycine, mouth tape, white noise machines, or expensive mattresses because none of those fix the root problem. Children do not have chronic circadian drift. They do not live in a constant sympathetic state. Their blood sugar is more stable. Their mitochondria are more efficient. Their nervous systems are not flooded with anticipatory stress. Adults have all of these issues layered together. So adults try to override biology instead of restoring it. That is the sleep industry in one sentence. One of the biggest blind spots in sleep discussions is safety. Sleep is a vulnerable state. The brain will not enter it unless it feels safe at a biological level, not a psychological one. Children feel safe because they are not responsible for outcomes. They are not anticipating tomorrow. Stress resolves quickly in their system. Their environment is predictable. Their bodies trust the signal to let go.

the most eloquently written yet understandable reasoning for insomnia i think i’ve ever read! can’t wait for the subsequent parts to this narrative
supplements for elderly dad with intermittent memory problems
Curious what the community might recommend in this situation. my 78 year old dad is finding himself not being able to think of certain words during conversations. He’s aware of it. His thought patterns are otherwise normal but i speak with him daily and see these patterns of struggle to remember certain things or think of the word he means to say. I know it’s a combination of atrophy of the brain and micro vascular atherosclerosis in the brain causing this. Peptides are not an option for him. He will not inject. curious if anyone found anything particularly useful for an aging parent with the same type of memory lapses? Thanks!!!

Thanks LS! solid recs indeed!! i just ordered my dad some lions mane. I may try the plasmologens on myself first and then try them on him. The ketones are also something i may trial first as well. what brands do you recommend?
PEMF...Apollo Neuro vagus nerve stimulator
Anthony has a great Instagram post giving a nice summary of PEMF applications. I start my day with 30-45minutes on my Healix Revive PEMF mat (also do box breathing and nasal breathing during this time, add in redlight devices and turn on my skylab 10,000lux light to get my circadian rhyms going). I drink my hydrogen water during this time and do mitochondrial peptides well (Ss-31and/or Mots-c), then i do fasted cardio. I end my day with the PEMF mat and red light on the body parts I've trained. Sleep and overall nervous system function has neen amazing since starting this routine. I have an Apollo Neuro vagus nerve stimulator that I wear all day and while sleeping. It's got some really great programs for energy, calming, focus, sleep and even a power nap program. Has anyone else used these devices? I would love to hear input on application and experience. I workout 2-4x per day (strategically planned) and I feel great every day. I do have a full-time (and then some) job and have found the PEMF and Apollo Neuro to have made a dramatic improvement in energy, recovery, mood and overall performance in the gym and work/life. I love toys - any recommendations on use or other toys to stack I would love to hear about. My latest purchase was the Chroma Iron Forge Redlight device (1joule/sec fluence rating - game changer for red light therapy). I look forward to learning from everyone.

wondering if anyone has experience with the haelo pemf disc? it’s promoted by dave asprey and is over 3 grand! wondering if it’s the same effects as the Healix revive mat which is a much better price
peptide source
I’m wondering where everyone gets their injectible peptides from? Anthony, does SSRP have a preferred source that us in the community could purchase from? Any online clinic where a virtual consult could be done and the peptides prescribed from a compounding pharmacy and shipped to our residence? I have a functional medicine doctor in miami but he requires you pick them up and they are already reconstituted which affects their expiration.
protocol for immunity
Hi Anthony and other fellow learners. I unfortunately, the past couple of years have developed a pattern of getting sick (and presently) with an upper respiratory infection about every 3 or 4 months. It typically lasts about 2-3 weeks. I test each time and it’s not influenza or covid. Each time there seems to be a stressful event in my life that happens that leaves me susceptible to infection. I did do a vial of thymosin alpha 1 when i got sick this summer at the onset. I noticed i was still sick for maybe a week and a half but my symptoms were less intense. It seems like every time i get on a decent fitness regimen and am consistent i get sick and it’s a constant setback. Since i am aware of the stressors that precipitate my viral illness it seems to me like my heart rate variability is highly involved in this process. I would like to know what your best advice is Anthony to have a steel like immune system. My system is definitely compromised. I did get an extensive lab work up with a functional medicine doctor about a year ago and nothing but some minor systemic inflammation was found everything else was normal. I’m 46, exercise 3 times a week consistently and have what i would consider an average diet. My sleep isn’t the greatest. My coworkers are even getting concerned about me with how frequent im sick. Supplement regimen includes a quality multivitamin, magnesium, coq10, pqq, urolithan a, dha fish oil, fatty 15, carnosine, vitamin d (my level is optimal) , creatine, taurine. during illness i’ve tried taking high doses of zinc, vitamin d, quercetin but none of those impacts the severity or duration of illness. I’m a pharmacist and definitely not holding anything anyone replies here as medical advice just trying to see what has worked for others! Thank you all so much! Scott

@Anthony Castore Thank you! your description as i was reading it completely hit home and you nailed it! i couldn’t agree more with the interpretation. I do have generalized anxiety and yes my brain is always on autopilot. Has anyone experienced true success with increasing their HRV and increasing vagal tone, Other than more staggered training and mindfulness and breathing? what have others experienced, perhaps device wise, that has helped increase HRV? I used to wear my aura ring and admittedly my HRV would always be in the upper 20s when healthy . When i would get really sick it would dip down into the single digits at times.
