The standard explanation is that ketamine blocks NMDA receptors. These receptors bind glutamate, which is a chemical messenger found throughout the brain and body. By blocking NMDA receptors, ketamine increase "brain-derived neurotrophic factor" (BDNF), a protein which I refer to as "Miracle-Grow for the brain." BDNF promotes neuroplasticity-which is the growth of new connections (synapses) in the brain. This has traditionally been viewed as the primary mechanism responsible for ketamine's therapeutic benefits. But ketamine does so much more!

A groundbreaking study found that adults who sit for 10 or more hours daily face a significantly higher risk of dementia compared to those who sit less. The research, which tracked over 50,000 adults using wearable devices, revealed that the risk increases dramatically after crossing that 10-hour threshold.

If you're going to prioritize one thing for your brain health, make it this: regular aerobic exercise. Multiple large-scale studies show that aerobic exercise doesn't just keep your heart healthy-it directly impacts your brain structure. One year of aerobic exercise in older adults led to significantly larger hippocampal volumes and better spatial memory. Other trials documented that exercise actually slows age-related gray matter volume loss.

Your brain is an incredible network of over 160 billion cells linked by over 100 trillion connections. Each day and each moment, it's being influenced by the choices you make. While no single signal or chemical determines your brain's fate, incredible scientific research over the last few decades have revealed that a certain molecule produced by your body's cells may be uniquely capable of growing your brain and even growing new brain cells.

Walking and diet are two of the simplest ways we know to boost BDNF, a key protein that helps brain cells grow, repair and communicate. Higher BDNF levels are strongly linked to better memory and slower cognitive decline.
