Yoga Makes Us Smarter

Think about how we feel when we are stressed. We might eat more, lose our appetite, sweat profusely, or simply want to bury our troubles in mindless television or computer games. What happens to our brains when we are under stress is that our bodies increase the secretion of cortisol, a well-known stress hormone. When faced with sustained, high levels of chronic stress, the associated high levels of cortisol can actually be toxic and even fatal to our brain cells. Because our hippocampus, the part of the brain responsible for memory and learning, is particularly vulnerable to high sustained cortisol levels we may ultimately compromise our learning and memory capacities when faced with uncontrolled chronic stress. By managing stress through yoga and meditation, you can actually improve your memory, concentration, and your ability to learn.

While researching the effects of long-term yoga and meditation, I found an intriguing study that reported improvements in attention, mood and stress over a very short time period. When a group of 40 undergraduate students were given 5 days of 20-minute meditation training, this group showed significantly better attentional abilities and control of stress than a similar control group of 40 students given only relaxation training, including greater improvement in attention, lower anxiety, depression, anger, and fatigue, and an elevated mood. There was also a significant decrease in stress-related cortisol.

These studies, which are just a few of those being conducted today, clearly show a strong relationship between our ability to maintain attention and our responsiveness to stress and emotional reactivity. In other words, the more one practices the contemplative skill of controlling attention through meditation and yoga, the more one has a manageable stress response and improved emotional reactivity. Ultimately, our cognitive performance is most efficient and at its optimal level when we are more in control of our stress and emotions.

Yoga-Brain Fact

Sustained, high-levels of stress can be toxic to our brain cells. The more you practice yoga and meditation, the more efficiently your brain will function.
