John Ratey has compiled great research within each chapter addressing specific conditions such as anxiety, depression, ADHD, stress, menopause, and aging. And, he conveys how exercise improves all those conditions.
Ratey dwelves in physiological details how exercise boosts the levels of various neurotransmitters, hormones, and proteins which in turn positively affect our overall health and cognitive capabilities including memory, learning, mood regulation.
Ratey conveys what specific type of exercises assist specific health situation and cognitive functions. There are tens of related interesting insights throughout the book. I am just mentioning a few examples below.
1) BMI and aerobic fitness are significant markers of academic performance.
2) Three neurotransmitters play a preponderant role in managing our moods, attention, perception, motivation, and movement. They are serotonin (mood), norepinephrine (focus), and dopamine (reward-system, movement). And, the pharmaceutical industry has focused on them: boosting serotonin to manage anxiety and depression; increasing dopamine to manage Parkinson). However, exercise boosts all three without any negative side effects.
3) Norepinephrine boosts the signal quality of synaptic transmission, while dopamine decreases the noise of neuron chatter. Together, they reduce ADHD and enhance learning.
4) Neurogenesis means we can grow neurons at any age. Stress, anxiety, and depression impair neurogenesis. But, exercise fights off those conditions and enhances neurogenesis.
5) A protein, brain-derived neurotrophic factor (BDNF), builds and maintain neurons and neuron networks. BDNF facilitates the learning process and is important for long-term memories. In addition to synaptic plasticity, BDNF also plays a role in energy metabolism. BDNF also ramps up serotonin levels that help with mood, depression, anxiety. And, exercise boosts BDNF levels.
6) An optimal exercise program combines a skill acquisition exercise and a aerobic one. Tennis and biking fits that. Skill exercise strengthens and expands neural networks. The more complex the movements the more complex the synaptic connections. Aerobic exercise enhances mood by boosting the levels of all three mentioned neurotransmitters.
7) You should vary the intensity of exercise. High intensity exercise boosts the human growth hormone (HGH) which also boosts BDNF. In combination, these are like a fountain of youth.
8) Doing squats can be as effective in boosting HGH levels as running hard for 30 minutes.
9) Paleolithic humans walked and ran 5 to 10 miles a day just to eat. Our sedentary lifestyle is not catered to our DNA, and explains the obesity crisis.
10) Active people reduce their cancer risk by 50%.
11) Every 50 minutes of weekly exercise correlates with a 50% drop in risk of depression.
12) Briskly walking 5 hours a week reduces the risk of gestational diabetes by 75%.
13) Women over 65 who remain physically active are 50% less likely to develop dementia.
14) Diabetes increases your risk of developing dementia by 65%. High cholesterol increases it by 43%. Exercise can assist with both conditions.
15) Exercise prevents inflammation that triggers the plaque accumulation in the brain that causes Alzheimer’s disease.
16) Among individuals over 75, the ones with higher blood glucose levels (but who were still not diabetic) had a 77% higher likelihood of developing Alzheimer’s disease.
17) Being overweight doubles the chances of developing dementia. And, when combined with high blood pressure and high cholesterol, the risk increases sixfold.
18) Exercise reduces the risk of colon cancer by 50%.

I'm 19 years old and find this book to be so interesting and helpful! I am a Dietetics major and I enjoy learning about health and fitness. I frequently run and workout and while I know it's good for my body,I haven't learned all the science behind why it is so good. This books breaks it down and gives great detailed information as well as making it understandable for any age. I think this book is a great eye opener as to why exercise is so important.

Hands down, the most helpful wellness book I have read in past ten years, and re-read 6 times. BTW, I have read one non-fiction book per week since 1985, so I select my reading material carefully. I am recovering from spinal surgery and enrolled in intense physical therapy three days weekly. This book and the Doc's recommendations have become my guidebook to wellness. My 'amazing progress' (as described by my 2 doctors) is proof Doctor Ratey knows what works and why. This book is a must-read for anyone who is serious about their longevity. I'm 73.

Wow! This book is almost as life changing as exercise itself! I HIGHLY recommend it to anyone but especially someone who doesn’t exercise and is maybe struggling with higher levels of stress, which many of us are during these uncertain times. The author goes into such detail on the effects of exercise on the brain. Each chapter covers a different issue... i.e. anxiety, depression, ADD...etc and then in the end he gives recommendations on how much to exercise and what exercise to do. The book is FILLED with tons of studies on the specific brain changes that go on during exercise. It does have a slow start in the beginning but once you get to the chapter of stress it becomes even more interesting. I plan to reread the book and highlight some of my favorite quotes and passages.

Spark " will " change the way you look at exercise and fitness. " Movement is life ". I am depressed and overweight and hate exercise with a passion. Since my perspective has changed I make myself do it. I still hate it but now I exercise regularly because it really does make me feel less depressed. To prove my point start a journal on how you feel every day. Do it for a week. Then start exercising and compare journal entries. If I didn't experience it first hand I would say it is just another person trying to sell a book. And if you have children in school you'll definitely get them moving.

I realized I was having trouble with my memory, forgetting names & words on occasion, but put it down to "just something that happens". I was a bit sad, too, since I "knew" it would continue to decline. After reading this book, I realized I can change that outcome and improve my memory significantly. A ton of research has been done in neuroscience over the last 15 years, but this was the first I'd heard of it! I immediately put into practice the recommendations and over the last month & a half have noticed definite signs of improvement. If you are willing to change your diet and to start exercising regularly in order to retain and improve your memory, this is the book for you. It was not an easy read due to some usage of medical terminology, but it works. I recommend that you just say "this thing" when you run across a tech term, because by the end of the book what is needed is explained in language anyone can understand.

As a mental health professional who works with the brain, I have implemented several additional strategies to my work such as nutrition and functional medicine. However, with "Spark" I have found that the missing ingredient in the recipe was exercise. Now, I will use it in combination with brain training at my clinic to improve the lives of my clients even further. A great book which contains valuable and useful information as well as a easy, comprehensible read. Many people will think, "well, duh!" yet they may fail to grasp the importance of the science the book mentions.

I’ve actually started to enjoy exercise!
Reviewed in the United Kingdom on June 7, 2019Verified Purchase
Something switched in my brain after reading this. For the first time in my life I’ve started to see exercise as a reward and as something to look forward to instead of a chore. I bought a Fitbit straight after reading so I could track my heart rate and get it to the optimal levels as described in the book, so now exercise has become a bit more like a game and an experiment which appeals to me a lot more. We all know that exercise is good for you and I wondered what this book could tell me that I didn’t already know, but it had much more of an impact than I ever thought it would. Well worth a read if you suffer with anxiety, depression and ADHD especially.

Do sport, it will change your life
Reviewed in the United Kingdom on June 8, 2019Verified Purchase
Ratey's research shows us something incredible - that exercise is good for the brain. He dives into the mechanics of this, but if you want to know the actionable steps, then do aerobic exercise. If you want to really build resilience, then do aerobic exercise that requires skill. And if you really, really want to get the brain benefits from exercise, do something that is social as well - e.g. something like a team sport.

However, recently I have some difficulty in my life as a student, i feel to stress and seeking out for solution. Luckily to find this book that help me a lot with my studies and stress managment.

Why would a reader of a book like this value the opinion of the Daily Fail on the front page!
The paperback book quality is poor recycled paper and not cut evenly. The paper is grey and text pale, ie poor contrast.
