Deliberate intention protects your pre-sleep environment. Keep indoor light below 10 lux in the three hours before bed to preserve melatonin. A low-wattage lamp provides the needed dimness. Will you lower the lights? 🕯️ #SleepHygiene themattwalkerpodcast.buzzsprout.com/1821163/episod…

Devices steal sleep through behavior rather than biology. Dr. Michael Gradisar notes that engaging content keeps you awake past your intended bedtime. Scrolling actively compresses your biological night. 🧠 #SleepHabits #Neuroscience themattwalkerpodcast.buzzsprout.com/1821163/episod…

Your body runs on an actual molecular timepiece. The suprachiasmatic nucleus uses 20,000 neurons to govern rhythms. Without a daily light cue, this clock drifts backward 14 minutes a day. 🕰️ #SleepScience #Circadian themattwalkerpodcast.buzzsprout.com/1821163/episod…

Is your light exposure wrecking your sleep? Morning sunlight sets your internal clock for the day, while evening light can delay your sleep-signaling melatonin by 90 minutes. It’s a simple switch for better sleep. #SleepScience #CircadianRhythm

Comprehensive screening serves as a primary defense against age-related decline. Proactive MRI ensures your health trajectory is determined by data-driven precision rather than accidental detection. 🧬 #Longevity #Health themattwalkerpodcast.buzzsprout.com/1821163/episod…

AI capabilities are doubling every seven months in medical imaging. This progression has already reduced scan times to 40 minutes and enhanced precise quantification of hippocampal volume. 🤖 #MedicalAI #BrainHealth themattwalkerpodcast.buzzsprout.com/1821163/episod…

Proactive medicine solves the false-negative trap of reactive care. Visualizing your biological landscape before symptoms appear allows for precise early detection and intervention. 🧠 #PreventativeMedicine #Health themattwalkerpodcast.buzzsprout.com/1821163/episod…

What if we could detect disease before symptoms? Dr. Daniel Durand of Prenuvo joins the podcast to discuss how whole-body MRI is changing preventive medicine, finding cancer and aneurysms early. Is proactive imaging the future of health? #PreventiveMedicine #MRI
