This episode is brought to you by AirDoctor.The most common explanation for why exercise makes us happy is far too simplistic. The psychological effects of movement cannot be reduced to just an endorphin rush. Physical activity influences many other brain chemicals, including those that give you energy, alleviate worry, and help you bond with others. It reduces inflammation in the brain, which over time can protect against depression, anxiety, and loneliness. Regular exercise also remodels the physical structure of your brain to make you more receptive to joy and social connection.  In today’s mini-episode, Dhru speaks with Dr. Kelly McGonigal, Ryan Glatt, and Dr. Rangan Chatterjee about how exercise can improve the treatment outcomes for depression and anxiety, how exercise decreases our chance of cognitive decline, and simple ways to build exercise into your everyday life.Dr. Kelly McGonigal is a health psychologist who specializes in understanding the mind-body connection.
