Lessons from the COVID-19 Pandemic — with Dr. Sanjay Gupta

Exercise & Brain

The relationship between exercise and brain health is more nuanced than previously thought. Sanjay Gupta explains that while intense exercise benefits cardiovascular health, it may not be as beneficial for the brain due to cortisol release, which counteracts brain-derived neurotrophic factor (BDNF) 1. Moderate exercise, however, promotes BDNF, enhancing brain function and potentially reducing dementia rates 2. Scott Galloway highlights the importance of avoiding extreme stress to protect brain health 1.

Extreme exercise, while being good for your heart and your muscles or whatever, is bad for the brain.

Gupta shares insights from indigenous tribes and blue zones, where moderate activity is a lifestyle, contributing to longevity and lower disease rates 3.

   

Brain Hacks

Sanjay Gupta discusses practical brain health hacks, emphasizing the potential for neurogenesis, or the growth of new brain cells, at any age 4. This challenges the old belief that brain cells are finite and only grow during infancy or after injury. He highlights the importance of moderate exercise and a healthy diet in promoting brain health and reducing cognitive decline 2.

The idea that you can grow new brain cells at any age... I found that incredibly inspiring.
