As we age, brain function gradually declines due to natural physiological changes, such as neuron shrinkage, weakened neural connections, and reduced blood flow to the brain. These changes negatively affect learning abilities, memory retention, and mental processing speed—prompting many to seek effective methods to preserve cognitive health.

While traditional advice like maintaining a healthy diet, regular exercise, adequate sleep, stress reduction, and staying socially active remains foundational, some lesser-known techniques may offer additional brain benefits by stimulating it in new ways.
In this context, Dr. Kevin Woods—neuroscientist and chief science officer at Brain.fm—shares three scientifically backed, unconventional habits that can be easily incorporated into your daily routine to sharpen mental focus and promote brain health:
1. Chewing Gum: An Unexpected Boost in Blood Flow
Though it may seem simple, studies show that chewing gum increases blood flow to key brain areas, including the prefrontal cortex and hippocampus—regions responsible for memory and attention. This enhanced circulation provides neurons with more oxygen and glucose, improving focus and reducing stress.
Dr. Woods recommends choosing sugar-free gum with long-lasting flavor. Surprisingly, one study even found that chewing hard objects—like wooden pencils—can elevate brain levels of the antioxidant glutathione. However, this method poses dental and digestive risks, making gum the safer and smarter choice.
2. Walking Backwards: A Brain-Rewiring Workout
Known as "reverse walking," this exercise goes beyond improving balance and muscle strength. It activates brain regions associated with planning and memory, as it forces the brain to concentrate on each step and process unfamiliar visual and motor cues.
Start slowly in safe, obstacle-free areas, keeping your posture upright and moving your feet carefully, beginning with your toes. This unusual movement helps challenge the brain in beneficial ways.
3. Humming: A Simple Sound with Profound Effects
Humming or producing a low buzzing sound can stimulate the vagus nerve, which connects the brain to vital organs such as the heart and lungs. Stimulating this nerve calms the nervous system and increases the production of nitric oxide, thereby enhancing cerebral blood flow.
Studies on choir singers have shown that regulated breathing through singing or humming can improve cognitive performance by strengthening neural networks involved in attention and concentration.
Dr. Woods emphasizes the importance of personal experimentation, noting that every brain responds differently. Regularly trying out these techniques and tuning into your body's signals can help you identify which method works best for you.
In conclusion, incorporating these small but powerful habits into your routine may help activate your brain in unexpected ways—offering a fresh alternative to traditional mental fitness strategies.
