Movement and the brain

As the saying goes, a sound mind in a sound body. Most people are aware that exercise makes us feel better. Previously it was believed that this was due to physiological factors only. However, recent studies have found that exercise improves our brain function. According to the latest meta-analyses, exercise increases the amount of grey matter, particularly in areas crucial for memory functions such as the orbitofrontal cortex and the hippocampus.

In today's technology-oriented world, we have become alienated from our natural need to move, hunt, and gather food. In terms of survival, immaterial things have replaced physical effort. Tragically, the lack of bodily exercise makes us unable to deal with the challenges that cause an ever-growing amount of stress on our minds.

Exercise has been found to increase the long-term potentiation of nerve cells, improving the ability to learn and memorize. Similarly, BDNF protein (Brain-Derived Neurotrophic Factor) levels have increased after physical activity. This has a positive impact on cognitive functions. The most significant increase of BDNF in the blood was found after aerobic exercise, particularly high-intensity activity. A study published in 2014 found that just one 20-minute strength training session significantly improves episodic memory.

Here is what the research has found considering various types of movement/exercise and the functions of the brain:

• Lifting weights helps improve complex thoughts, problem-solving and multitasking
• Practicing yoga and similar movements improves the integration of mind and body and helps deal with fear and anxiety
• HIIT training helps with appetite regulation, blood sugar regulation, and staves off addictions and cravings
• Sports drills and complex movement help improve attention, task switching, and visual-spatial processing
• Aerobic exercise helps improve memory and prevent cognitive decline

Have you tried a "walking meeting"?

When we walk, the brain functions better when compared to sitting. Hence having for example a walking meeting may serve both of the participants well.
