The Science of Better Sleep: Inside Bionic Health's Comprehensive Sleep Module

In the latest episode of Medicine 3.0, Bionic Health advisor Kelly Joniak and Dr. Catherine Isaac dive deep into one of our most popular offerings: the Sleep Module. This conversation reveals the multifaceted approach Bionic Health takes to help members optimize their sleep quality and understand the factors affecting their rest.

A Comprehensive Approach to Sleep Health

Dr. Isaac explains that Bionic's Sleep Module stands out for its thoroughness, combining multiple data sources to create a complete picture of a member's sleep patterns:

• Sleep diaries: Members record morning and evening sleep habits, providing insights into sleep quality, bedtime routines, and daytime factors affecting sleep
• Wearable data integration: Information from devices like Whoop, Oura, Apple Watch, or Garmin is analyzed alongside self-reported data
• Specialized assessments: Evaluations for stress, depression symptoms, sleep apnea signs, and chronotype (morning/evening preference)
• Laboratory testing: Thyroid function, basic metabolic panel, hormone levels including progesterone for women
• Cortisol measurement: Both serum and salivary cortisol testing to understand stress hormone patterns throughout the day

Key Insights from the Conversation

Understanding Your Chronotype

Dr. Isaac discusses how knowing whether you're naturally a morning person, evening person, or somewhere in between can help you optimize your schedule and understand potential sleep challenges. This is particularly relevant when family members have different chronotypes, requiring thoughtful coordination.

The Truth About Sleep Supplements

The episode covers several popular sleep aids with evidence-based perspectives:

• Melatonin: Most beneficial for elderly populations with naturally declining levels, shift workers, and travelers—not generally recommended for routine insomnia. Dr. Isaac cautions that over-the-counter supplements often contain higher doses than necessary.
• Ashwagandha: May help reduce cortisol levels and has anxiety-reducing properties that can improve sleep onset.
• Magnesium: Dr. Isaac specifically recommends magnesium threonate for sleep as it's the only form that crosses the blood-brain barrier.
• CBD: May reduce core body temperature (potentially facilitating sleep onset), but insufficient research exists on its effects on sleep architecture.

Wearable Data vs. Reality

A fascinating discussion explores the discrepancies between wearable sleep tracking data and self-reported experiences. Dr. Isaac cautions against letting your wearable device "tell you how to feel," citing research showing how suggestible we are about our sleep quality.

Lifestyle Factors Affecting Sleep

The episode covers practical recommendations about:

• Caffeine consumption (ideally limited to 1-2 cups before 1-2pm)
• Pre-bedtime activities (with warm showers or baths recommended over screen time)
• The relationship between exercise, nutrition, and sleep quality

Why Sleep Matters (But Don't Stress About It)

Dr. Isaac strikes a thoughtful balance, emphasizing that while consistent quality sleep is important for health, occasional poor nights aren't cause for alarm. The research on sleep's health impacts primarily concerns chronic patterns over years, not occasional disruptions.

"I find that when I'm actually doing the review of the sleep data, I find that to be really interesting and I think to help provide important insights," Dr. Isaac notes, highlighting how the module helps members understand their unique sleep patterns.

Understanding Brain Aging and the Fight Against Alzheimer's

In the latest episode of Medicine 3.0, Dr. Jared Pelo sits down with Dr. Christin Glorioso, physician, neuroscientist, and founder of NeuroAge, to discuss brain health, Alzheimer's prevention, and the cutting-edge science of measuring brain aging.

A Personal Mission Driven by Family History

Dr. Glorioso's journey into brain health research began with personal experience—her grandmother suffered from Alzheimer's disease, and she recently discovered she carries an APOE4 allele, which increases her own risk. This personal connection has fueled her 20-year career studying brain aging and what can be done to slow it down.

"My life has been dedicated to coming up with better solutions for people who have high risk of Alzheimer's, which if anyone lives long enough, that's really all of us," Dr. Glorioso explains.

The Science of Brain Aging

After completing her MD-PhD at the University of Pittsburgh and Carnegie Mellon, followed by postdoctoral work at MIT, Dr. Glorioso has focused on understanding the molecular changes that happen in the brain as we age. Her research reveals that approximately 2,000 RNA transcripts (about 10% of the genome) change with age in ways that can either protect against or increase the risk of neurodegenerative diseases.

One of the most encouraging findings: people whose brains are biologically five years younger than their chronological age are significantly protected from Alzheimer's disease—even if they carry genetic risk factors like the APOE4 allele.

The 40% We Can Control

While genetics plays a significant role in brain aging, Dr. Glorioso emphasizes that approximately 40% of our risk is determined by lifestyle factors we can control:

1. Exercise - At least 30 minutes daily, with particular benefits from getting your heart rate into zone three, which releases BDNF (brain-derived neurotrophic factor)
2. Diet - Mediterranean diet, coffee, tea, and foods rich in polyphenols (like berries)
3. Social connection - At least an hour of social time daily
4. Stress reduction - Cortisol is particularly harmful to brain cells
5. Mental activity - At least an hour daily of mentally challenging activities
6. Sleep - Quality sleep is essential for brain health

Measuring Brain Age

NeuroAge has developed multiple approaches to measuring brain health:

• RNA biomarkers - Blood tests measuring 52 RNA transcripts
• Cognitive testing - "Neuro games" that assess various cognitive functions
• MRI brain imaging - Measuring volumes of 26 different brain regions
• Genetic testing - Identifying genetic risk factors

While MRI provides the most accurate assessment followed by blood biomarkers and cognitive testing, Dr. Glorioso notes that even simple cognitive tests can help determine whether memory issues are normal for your age or potentially concerning.

The Future of Alzheimer's Prevention

Beyond testing, NeuroAge is working toward developing therapies to reverse brain aging—essentially creating a "statin for Alzheimer's" that could safely prevent the disease. The data collected through their testing program contributes to this research in a privacy-protected way.

"We're creating therapies to reverse brain aging... something that's safe, you know, a pill that people can take that is going to prevent Alzheimer's in the future," Dr. Glorioso shares.

This partnership between Bionic Health and NeuroAge represents an exciting opportunity for members to assess their brain health and take proactive steps toward preventing cognitive decline. As Dr. Pelo notes, even without extensive testing, everyone can benefit from living as though they're at high risk—the lifestyle interventions that protect brain health also enhance overall quality of life.

Brain Health: How Music and Lifelong Learning Can Prevent Cognitive Decline

In our latest Bionic Health podcast, Dr. Jared Pelo interviews neurologist-turned-entrepreneur Dr. Josh Turknett about the science of brain health, cognitive decline prevention, and how learning complex skills like music can help maintain brain function as we age.

From Neurologist to Music Education Innovator

Dr. Josh Turknett's journey is anything but conventional. After completing medical school and a four-year neurology residency at the University of Florida, he spent years in private practice treating neurological conditions. But over time, he began to recognize a significant gap between what he could offer patients in clinical practice and what he believed they truly needed.

"I came to realize that a lot of the issues I was seeing as a neurologist were related to lifestyle and preventable types of things," Dr. Turknett explains. Through his own experience with migraines, he discovered that dietary changes had a more profound impact on his condition than conventional treatments—a revelation that would eventually lead him to reconsider his entire approach to neurological health.

While still practicing neurology, Dr. Turknett pursued his passion for music, specifically the banjo. Drawing on his background in cognitive neuroscience, he began integrating principles of neuroplasticity into his musical practice. This eventually evolved into BrainJo, an innovative platform that teaches musical instruments through neuroscience-based approaches.

The "Stimulate and Support" Framework for Brain Health

When it comes to maintaining cognitive health, Dr. Turknett advocates a simple yet powerful framework: stimulate and support.

"There are two things to think about in terms of keeping a healthy brain throughout our life," he says. "We have stimulation on one side and support on the other side."

Stimulation: Fighting Autopilot Mode

Cognitive stimulation is essential for maintaining brain health, but Dr. Turknett points out that many of us, especially in established careers, operate largely on autopilot. "The more you can spend your day on autopilot, the less cognitive stimulation you've provided," he explains.

Real cognitive stimulation comes from activities that trigger plastic reorganization in the brain—essentially, learning new knowledge and skills. This is where complex activities like learning a musical instrument come in.

BrainJo currently offers instruction in multiple instruments:

• Two styles of banjo (claw hammer and fingerstyle)
• Piano
• Ukulele
• Fiddle
• With guitar coming soon

Support: Giving Your Brain What It Needs

Just as important as stimulation is providing your brain with the resources it needs to maintain existing neural connections and build new ones. Dr. Turknett identifies several key pillars of brain support:

1. Physical activity - Particularly activities that combine cardiovascular fitness, strength training, and cognitive demands (like tennis or pickleball)
2. Sleep and rest - Critical for neural recovery and consolidation
3. Nutrition - Including key nutrients like B12, vitamin D, magnesium, zinc, and copper
4. Stress management - Limiting chronic stress that can damage brain tissue
5. Social connection - Perhaps the most underappreciated factor in brain health

On the often-overlooked importance of social interaction, Dr. Turknett notes: "Being around other people, conversing with other people, being in social situations is an enormous cognitive stimulus... one of the reasons that we see [cognitive] deterioration is because of the loss of that stimulus when people are isolated."

Assessing Cognitive Risk and Monitoring Brain Health

Many people, especially those with family histories of dementia or genetic risk factors like APOE4, wonder how to assess their risk for cognitive decline. Dr. Turknett emphasizes that while there's no single test that can definitively predict risk, there are several approaches to monitoring brain health:

• Regular cognitive assessments, whether through formal testing or self-monitoring
• Basic blood work to identify conditions like metabolic syndrome or nutritional deficiencies
• Lifestyle evaluation to identify areas for improvement

He recommends foodforthebrain.org for those interested in comprehensive cognitive evaluation with a nutritional focus.

Rather than viewing cognitive health as predetermined, Dr. Turknett stresses that "we are actively influencing our risk all the time." This empowering perspective frames brain health as something we can continuously improve through our daily choices.

Anyone Can Play Music: The Science of Learning at Any Age

Dr. Turknett's new book, "Anyone Can Play Music: How to Realize Your Musical Potential with the Laws of BrainJo," challenges the common belief that learning complex skills like music becomes impossible as we age.

"The reason we can learn anything at any age is because we have this ability to change the brain at any age," he explains. "Learning complex skills relies on neurological mechanisms that we all share."

The book outlines principles for leveraging these natural mechanisms, often requiring readers to unlearn ineffective approaches taught in traditional education. It's as much about how to learn anything as it is about music specifically.

A Prescription for Brain Health

For someone in their mid-40s concerned about future cognitive health, Dr. Turknett recommends:

1. Evaluate your current cognitive stimulation - Is your work challenging your brain, or are you on autopilot?
2. Incorporate complex real-world skills - Music, dance, or sports that demand coordination and strategy
3. Ensure physical fitness - Combining low-level movement, resistance training, and occasional high-intensity exercise
4. Monitor nutritional status - Particularly for B12, vitamin D, and other brain-essential nutrients
5. Prioritize social connection - Ideally through activities that simultaneously provide cognitive stimulation

The key is finding activities you enjoy that provide both cognitive challenges and social connection—like joining a community of musicians or picking up a sport like pickleball that combines physical activity, strategy, and social interaction.

Beyond the Clinic: Making a Broader Impact

Dr. Turknett's transition from clinical practice to entrepreneurship reflects his desire to have a greater impact on brain health than the constraints of a traditional medical practice would allow.

"To actually fulfill the role that I initially signed up for... I could do a much better job doing what I'm doing now than I could in the clinic," he reflects. Through his online platform, books, and educational content, he's able to reach and help far more people than would be possible seeing patients one at a time.

This sentiment resonates with Dr. Pelo, who made a similar transition from emergency medicine to focusing on preventative health through technology. Both physicians recognize that while there will always be a need for excellent clinicians, there's also tremendous value in creating scalable approaches to health that can benefit millions.
