  Why Quitting is So Hard: Understanding Addiction

  Aug 12, 202617 min

  Addiction affects millions of people, yet stigma and misunderstanding often prevent people from seeking help. In this episode of Health Matters , host Courtney Allison speaks with Dr. Jonathan Avery, an addiction psychiatrist at NewYork-Presbyterian and Weill Cornell Medicine, about the realities of addiction and recovery. Dr. Avery explains that addiction is more than a problem of willpower. Drawing on research and clinical experience, he discusses how genetics, mental health, trauma, social factors, and brain chemistry all play a role in the development of substance use disorders and behavioral addictions. The conversation examines how addictive behaviors, from alcohol use and opioid dependence to gambling and social media use, affect the brain's reward system and why quitting can be so difficult. Dr. Avery also shares how newer treatments, including medications and emerging research on GLP-1 medications, are changing the landscape of addiction care. Finally, Dr. Avery discusses the importance of reducing stigma, building supportive communities, and recognizing that recovery is possible. He offers practical advice for people who may be struggling themselves as well as guidance for supporting loved ones with compassion and understanding. Chapters 00:00 – What Is Addiction? Why addiction is more than a substance, the role of trauma and mental health, and what happens in the brain 05:05 – Gambling, Screens, and Modern Addictions How behavioral addictions affect the brain and why smartphones have changed the landscape 09:00 – Treatment, Recovery, and New Hope Available therapies, medications, emerging GLP-1 research, and why most people do get better 11:30 – Breaking Stigma and Supporting Recovery Why connection matters, how addiction overlaps with mental health, and ways to support loved ones Key Topics Covered Addiction Recovery Substance use disorders Alcohol use disorder Opioid addiction Fentanyl epidemic Behavioral addictions Gambling addiction Social media addiction Gaming addiction Nicotine and vaping Dopamine and reward pathways Withdrawal Mental health and addiction Trauma and addiction Addiction stigma Recovery support Community and connection Addiction treatment Medication-assisted treatment GLP-1 medications Self-medication hypothesis Depression and addiction Anxiety and addiction Addiction psychiatry Key Takeaway Addiction is a complex health condition influenced by brain biology, mental health, life experiences, and environment, not simply a lack of willpower.

  How to Improve Your Posture and Prevent Tech Neck

  Jul 29, 202616 min

  Back and neck pain have become increasingly common in the digital age. Many of us spend hours each day sitting at desks, working on computers, or looking down at our phones, often without realizing the impact these habits can have on our spine. In this episode of Health Matters , host Courtney Allison speaks with Dr. Joseph Lombardi, an orthopedic spine surgeon at Och Spine at NewYork-Presbyterian, about why posture matters and what happens when poor positioning places excess strain on the neck and back. Dr. Lombardi explains the mechanics of the spine and how spinal discs function as shock absorbers between the vertebrae. He discusses the phenomenon known as "tech neck" or "text neck," describing how tilting the head forward dramatically increases stress on the cervical spine and may contribute to disc degeneration over time. The conversation also covers practical ways to support spinal health. Dr. Lombardi shares tips for setting up an ergonomic workstation, explains why sitting and slouching increase pressure on the lower back, and discusses the importance of taking movement breaks throughout the day. Finally, he highlights exercises that can strengthen the core and support better posture and outlines warning signs that may indicate a more serious spinal condition requiring medical attention. Chapters 00:00 – Tech Neck and the Hidden Stress on Your Spine How looking down at phones and computers increases strain on the neck and what happens to spinal discs over time 03:58 – Why Posture Matters for Long-Term Spine Health The connection between poor posture, disc degeneration, sciatica, and age-related changes in the spine 06:30 – Ergonomics, Sitting, and Building Better Habits Simple workstation adjustments, standing desks, movement breaks, and ways to reduce pressure on the spine 09:00 – Exercises, Prevention, and When to See a Doctor Core-strengthening exercises, healthy movement habits, warning signs of serious spinal issues, and practical tips for lifelong spine health Key Topics Covered Posture and spine health Tech neck and text neck Neck pain Back pain Disc degeneration Spinal discs and biomechanics Ergonomic workstations Standing desks Sitting posture Slouching and spinal stress Core strength Lumbar support Bird dog exercise Planks and core stability Sciatica Cervical spine health Lower back pain Sedentary lifestyles Healthy aging and the spine Physical therapy Spine injury prevention Orthopedic spine surgery Workplace ergonomics Musculoskeletal health Key Takeaway Good posture is about more than standing up straight. Everyday habits like looking down at a phone, slouching at a desk, and sitting for long periods can place significant stress on the spine and contribute to pain and disc degeneration over time. By improving workstation ergonomics, staying active, strengthening the core, and addressing symptoms early, people can take meaningful steps to protect their spine and support long-term musculoskeletal health.

  From Night Sweats to Brain Fog: How to Navigate Perimenopause

  Jul 1, 202616 min

  Perimenopause is having a moment, but for many women, it can still feel confusing, unpredictable, and difficult to navigate. In this episode of Health Matters, host Courtney Allison speaks with Dr. Cassandra Simmons, chief of obstetrics and gynecology at NewYork-Presbyterian and Columbia, about what’s really happening during this transitional phase. Dr. Simmons explains that perimenopause is driven by fluctuating levels of estrogen, progesterone, and testosterone, which can begin as early as a woman’s 30s and last for several years. These hormonal shifts can lead to a wide range of symptoms—from hot flashes and night sweats to brain fog, mood changes, joint pain, and sleep disruption. The conversation focuses on vasomotor symptoms like night sweats and why they can significantly impact energy, sleep quality, and daily functioning. Dr. Simmons also discusses the emotional and cognitive effects of perimenopause, including the common feeling of “just not yourself.” Finally, Dr. Simmons outlines treatment options in three categories: holistic approaches such as supplements and lifestyle changes, non-hormonal prescription therapies, and hormone replacement therapy. She emphasizes individualized care, the importance of understanding the whole patient, and how modern hormone therapy has evolved to be safer and more tailored than in the past. Chapters 00:00 – What Is Perimenopause? How hormone changes drive symptoms and why timing varies for every woman 03:15 – Hormones and Symptoms Explained The role of estrogen, progesterone, and testosterone in sleep, energy, and mood 07:45 – Why Night Sweats Disrupt Daily Life Understanding vasomotor symptoms and their impact on sleep and function 12:00 – Treatment Options and Lifestyle Support From supplements and therapy to hormone replacement and exercise Key Topics Covered Perimenopause definition Hormone fluctuations (estrogen, progesterone, testosterone) Night sweats and hot flashes Brain fog and cognitive symptoms Sleep disruption and fatigue Emotional and mood changes Weight, metabolism, and muscle mass Bone health and estrogen decline Holistic supplements and nutrition Hormone replacement therapy (HRT) Non-hormonal treatment options Lifestyle strategies for symptom management Takeaway message: Perimenopause can affect nearly every part of the body, but understanding what’s happening hormonally is the first step toward feeling better. With a combination of lifestyle changes, supportive therapies, and personalized care—including hormone treatment when appropriate—women can manage symptoms and maintain their health and well-being through this transition. Doctor Bios Dr. Cassandra Simmons is the chief of general obstetrics and gynecology at NewYork-Presbyterian/Columbia University Irving Medical Center. In this role, Dr. Simmons directs clinical operations for the division of General Ob/Gyn, with the goal to deliver the highest quality of care to patients.
