Are you looking for ways to create nourishing meals without exhausting yourself? Our next Cooking for POTS group visit is happening this Friday, May 15, and we'd love to have you join us!

What You'll Learn: Sheet Pan Meals Made Simple

Led by Ruben Lespron, RD, this class focuses on true one-pan cooking designed to minimize prep, dishes, and standing time. If the thought of cooking leaves you feeling drained before you even start, this session will change the way you think about meal preparation.

You'll discover how the same ingredients can be roasted and seasoned in several different ways to create flavorful, complete meals with very little hands-on effort. It's all about working smarter, not harder, in the kitchen.

Class Highlights:

Minimal prep techniques that save energy – Spend less time on your feet and more time resting. We'll show you shortcuts that actually work.

In our latest "Brain Train Class," Dr. Cheng Ruan shared transformative insights into how our daily emotional lives, breathing patterns, and physical connections directly impact our cognitive longevity. Far from being just "mental" states, our feelings and social interactions are deeply rooted in our physiology. By understanding these mechanisms, we can move away from complex treatments and toward a life of clarity and health.

1. The Vital Need for Connection and Emotional Expression

Dr. Ruan highlighted that human connection is a physiological necessity. Social isolation and suppressed emotions aren't just lonely; they accelerate brain fog and cognitive decline. Research shows that skin-to-skin contact and genuine emotional expression help regulate heart rate, blood sugar, and temperature.

Critically, Dr. Ruan addressed the "hero mentality." Societal pressure to remain stoic—often seen in high-stress roles like first responders—can actually lead to higher rates of dementia. Suppres...

At the heart of any thriving community lies the personal growth and resilience of its members. In our recent quarterly reflection session, the Unboxing You series hosted by Dr. Cheng Ruan, we delved deep into what it means to lead oneself and how centering practices can transform our health and outlook.

The Foundation of Self-Leadership

Leadership is often viewed as a role of external authority, but our discussion redefined it as an act of empowering others through self-mastery. True leadership starts from within—leading oneself with two essential ingredients: awareness and compassion. By pairing these, we create a foundation of centering that allows for empathy, loyalty, and courage.

Embracing the "Sloth": The Art of Dynamic Waiting

One of the most profound concepts shared was "dynamic waiting." In a world that prizes hyperactivity, we often mistake stillness for laziness. However, non-doing is actually a state of constant, non-judgmental observation. Like the sloth—the ultimate s...

In a recent group visit discussion led by Dr. Cheng Ruan, we explored the transformative concept of "permission" within the autonomic nervous system. Autonomic dysfunction, or dysautonomia, is often a physical manifestation of the body negotiating with its environment through a series of subconscious permissions.

The Body as an Ecosystem

A radical shift in perspective is required to understand our biological responses. Viruses, for example, should be viewed less as foreign invaders and more as ancient environmental code. They engage with our genetic makeup—constituting nearly 20% of the human genome—to trigger necessary immune responses. Symptoms like tachycardia, fever, and fatigue are not failures of the system but intentional efforts by the body to "stir the water," increasing blood flow velocity and internal heat to allow immune components to interact effectively with these environmental inputs.

The Cost of the "High-Performer" Identity

One of the most significant barriers to r...

Many of us have experienced that sudden, sinking feeling when we forget where we put our keys or why we walked into a room. We often label these "senior moments" and worry about cognitive decline. However, recent discussions suggest a different perspective: the root cause of perceived memory loss in our modern world is frequently overstimulation rather than actual memory failure.

Brain Health and Overstimulation

In an era of constant notifications and task-oriented living, our brains are often stuck in the "task positive network" (TPN). This state of perpetual doing prevents us from grounding ourselves and engaging the "default mode network" (DMN)—the part of our brain responsible for our internal narrative and emotional processing. When we suppress our emotions and overtax our cognitive load, our brains become overwhelmed, leading to what feels like memory loss but is actually a lack of presence and focus.

11 Keys to Healing When "Trying Harder" Stops Working
There is a specific kind of exhaustion that comes when your body becomes a problem you can’t solve.

For many high performers, health issues are treated like a broken project. We bring the same tools to our healing that we brought to our careers: more research, more protocols, more effort, more "doing." But when it comes to the complex interplay of the nervous system, the immune response, and the spirit, the tools of accumulation often become the very things that keep us sick.
This is not "information." You likely have enough of that. This is about  Access. 

The following 11 Keys are not a checklist for you to implement while your system is screaming. They are access points. They are a map for moving from a state of "defense" back into a state of "being."
1. The Key of Center: Regulation is the Prerequisite
In the world of chronic health challenges, we are taught to think our way out of our symptoms. We analyze labs, track data, and o...

Springtime often inspires us to declutter our homes, but it is also an ideal season to "Marie Kondo" our health. When living with conditions like hypermobility, POTS, and dysautonomia, our symptoms can feel like unwanted clutter. However, by peeling back the layers of these symptoms, we can find a path to peace and autonomic balance.

Peeling Back the Layers

When a symptom like fatigue or a migraine arises, try looking at it curiously. Ask yourself why it's there. You might find that fatigue is actually a response to dysregulated sleep, which stems from a fight-or-flight response. By peeling back at least five layers of "why," you shift your brain from a state of danger (the amygdala) to a state of reason (the prefrontal cortex). This curiosity actually lowers inflammation and histamine responses.

The Power of Ritual and Grounding

Humans naturally reach for where it hurts—a form of self-love that blunts pain receptors. We can turn these natural tendencies into intentional rituals. W...

In our latest "Brain Train" session, Dr. Ruan led a comprehensive discussion on the profound systemic effects of pollen and common allergens, emphasizing the critical link between environmental triggers and brain health.

The Allergy-Brain Connection 

Microscopic images reveal that pollen, like viruses, features spikes that attach to the body, triggering an immune response, specifically the production of histamine and mucus. This systemic reaction, which the brain perceives as an invader threat, can lead to:

• Systemic Mucus Buildup: Mucus forms everywhere, including the throat, lungs, and gut.
• Sharpened Senses: The brain releases histamine—acting like a heightened "Spider-Man" sense—to sharpen smell, taste, and touch in response to the trigger.
• Mental Health Impact: The repeated release of histamine can mimic symptoms often diagnosed as anxiety, depression, memory loss, and attention deficit disorders.
• Dopamine Signals: Elevated histamine levels can prompt the brain to create ...

Most of us understand, on some level, that stress affects our health. But what if the story goes far deeper than stress? What if the foundational beliefs you carry about yourself — beliefs so ingrained they feel like facts — are actively shaping the chemistry of your body? Triggering your immune system. Disrupting your hormones. Generating the gut symptoms, skin flares, and chronic inflammation that no prescription seems to fully resolve? 

This is the central insight Dr. Cheng Ruan brings to the work at Texas Center for Lifestyle Medicine: our living beliefs are not just psychological phenomena. They are physiological events. And understanding them may be one of the most powerful levers we have for lasting health. 

What Is a Living Belief?

A living belief is a deeply held, often unconscious conviction about ourselves and the world — one that shapes how we interpret every experience we have. These are not the opinions we ho...

Brain fog is one of those experiences that almost everyone has had — yet it can be incredibly difficult to describe. It's subjective, it's frustrating, and it often feels like it comes out of nowhere. As a physician specializing in lifestyle medicine, I've spent years studying this phenomenon, and I want to share something that has transformed how I approach brain fog in my practice: there are actually five distinct types, and understanding which type you're experiencing can make all the difference in how you address it.

These five types are not isolated islands — they exist on a connected circle, each one capable of triggering the next. When brain fog strikes, it's rarely just one type in isolation. One type tends to act as the dominant trigger, setting off a rapid cascade through the others in a matter of microseconds.

Type 1: Hypoperfusion Brain Fog (Low Blood Flow)

The first and most foundational type is hypoperfusion fog — not enough blood flow reaching the brain. Gravity nat...
