John Quincy Adams, the 6th President of the United States who solidified early American diplomacy and national foundations following George Washington and John Adams, was renowned throughout his life as a symbol of diligence. Facing immense political friction and heavy executive pressure, how did he preserve sharp memory and cognitive vigor past the age of 80? 🏊♂️
Adams maintained a rigorous physical routine throughout his life: every morning before sunrise, he swam in the cold waters of the Potomac River or walked over 5 miles (approx. 8 km) along rugged forest trails at a rapid pace. Having elevated systemic blood flow, he sat quietly in his study each evening, meticulously recording key lessons and the essence of his daily reading into a handwritten diary. This synergistic routine balancing physical vigor and narrative reflection served as his cognitive shield.
In today’s post, we introduce the neuroscientific mechanisms of Brain-Derived Neurotrophic Factor (BDNF) release and synaptic reinforcement embedded in John Quincy Adams’s morning brisk walking and evening journaling routine.

1. Synergy of Exercise-Induced BDNF and Cognitive Reflection
Brisk walking at a pace that leaves you slightly breathless raises your heart rate and supplies rich blood flow to the hippocampus, directly stimulating the secretion of Brain-Derived Neurotrophic Factor (BDNF), a key neural growth factor. This factor repairs synaptic connections between brain cells and promotes new growth.
When you write a diary or reading notes by hand in the evening while your brain is optimized for learning, a synergistic effect occurs as long-term memories are precisely encoded into the neural circuits newly activated by aerobic exercise. This is a scientific routine that highly trains the prefrontal cortex’s Executive Function and attentional apparatus.
2. 3-Step Practical Routine for Modern Professionals
20-Minute Morning Brisk Walk
Walk for 20 minutes before or after breakfast at a fast stride where holding a long conversation with someone next to you feels difficult.
Focus on Footsteps and Sensory Experience of Nature
Instead of looking at your smartphone while walking, focus your sensory awareness entirely on the pressure under your feet, the cool morning air brushing your cheeks, and the surrounding scenery.
Writing a 3-Line Evening Reflection Journal
Open your physical diary in the evening and meticulously write down what you learned today or self-reflections in about 3 lines using a pencil or pen to anchor your learning pathways.
3. Adjust Speed to Match Your Knee Joints and Fitness Level
Adams engaged in a very fast 5-mile brisk walk every day, but this was based on physical endurance trained over a long period. If modern individuals suddenly start high-intensity walking, it can strain their knee joints or spine. Starting with 15 minutes of light brisk walking matched to your baseline fitness and gradually expanding the time and stride is the best way to avoid overexertion.
📌 Frequently Asked Questions (FAQ)
Can I substitute outdoor morning walks with running fast on an indoor treadmill? ▼
In terms of BDNF release via aerobic exercise, it is effective. However, outdoor walking is strongly recommended because processing outdoor visual stimuli (natural light, seasonal changes, uneven terrain) has a much greater effect on activating the visual cortex, sense of balance, and prefrontal synaptic networks compared to a static indoor environment.
Will typing the evening reflection journal into a smartphone memo app have the same effect? ▼
Writing directly by hand is much more effective. Holding a pen and writing stimulates the sensory receptors at the fingertips, precisely activating the brain's somatosensory cortex, which induces focus and multiplies the encoding effect on cognitive circuits. Typing on a smartphone keyboard is mechanical and provides significantly less brain stimulation.
