Yoga has been practiced for thousands of years and is known for its numerous health benefits. From reducing stress and anxiety to improving flexibility and balance, yoga has been shown to have a positive impact on both physical and mental health. But can it also make you smarter? Let's explore the evidence.

First, it's important to understand what we mean by "smarter." Intelligence is a complex trait that encompasses various cognitive abilities, including memory, attention, problem-solving, and creativity. While there is no single measure of intelligence, researchers often use standardized tests to assess different aspects of cognitive function.

One possible mechanism by which yoga may improve cognitive function is through its effects on the brain. Several studies have shown that yoga can increase gray matter volume in brain regions involved in cognitive function, such as the prefrontal cortex. Gray matter is the part of the brain that contains the cell bodies of neurons and is involved in processing information and making decisions.

A 2015 study published in the journal Frontiers in Human Neuroscience found that a 12-week yoga intervention increased gray matter volume in the hippocampus, a brain region involved in memory and learning, in older adults. The researchers suggested that the increase in gray matter volume may have contributed to the improvements in cognitive function observed in the study.

Another possible mechanism is through the stress-reducing effects of yoga. Chronic stress has been shown to have negative effects on cognitive function, particularly memory and attention. By reducing stress, yoga may help improve cognitive function in those who are experiencing stress-related cognitive decline.

A 2016 study published in the Journal of Alzheimer's Disease found that a 12-week yoga intervention improved cognitive function in older adults with mild cognitive impairment. The researchers attributed the improvement to the stress-reducing and relaxation effects of yoga.

A 2018 study published in the Journal of Psychiatric Practice found that yoga improved cognitive function in patients with major depressive disorder. The researchers suggested that the mindfulness and self-awareness practices in yoga may have contributed to the improvements in cognitive function. While more research is needed to fully understand the relationship between yoga and cognitive function, it seems that yoga may have some positive effects on it.

In addition to its effects on cognitive function, yoga has numerous other health benefits that may indirectly contribute to improved intelligence. For example, regular yoga practice has been shown to improve sleep quality, reduce inflammation, and boost immune function. These factors can all have positive effects on cognitive function.

While the scientific community is still only beginning to explore understand the relationship between yoga and intelligence, there is no denying that yoga has positive effects on the mind. Given the numerous other health benefits of yoga, it's worth considering adding it to your routine if you're looking to improve your physical and mental well-being.
