A noted neuroscientist reveals groundbreaking research on how fitness and exercise can combat mental health conditions such as anxiety, dementia, ADHD, and depression, and offers a plan for improving focus, creativity, and sleep.Jennifer Heisz shares paradigm-shifting research on how exercise affects the brain, finding that intervals of intense workouts, or even leisurely walks, help stop depression and dementia, lessen anxiety and ADHD, and encourage better sleep, creativity, and resilience. Physical inactivity is the greatest risk factor contributing to dementia and anxiety-it's as much a factor as genetics. In addition, exercise's anti-inflammatory properties make it the most effective treatment strategy for those who are depressed and don't respond to anti-depressants. The book focuses on overcoming inertia; using exercise to help fight addictions; how we can improve our memory with fitness even as we age; and, importantly, how exercise can help us sleep better, improve focus, and be more creative. Included are easy to use plans for unique aerobic and resistance workouts designed to strengthen the brain.
