My new book Magnificent Mind At Any Age is coming out 12/2/09. You can pre-order it on the website here. Starting 11/29 my new PBS special on this book will start airing across North America.
Here is Part Three of Six of what you can expect in the book.
Boost Blood Flow
Blood is especially important to the brain. Even though the brain is only 2% of the body’s weight, it uses 20% of the body’s blood flow and oxygen supply. Blood flow to the brain is rarely thought about as important by the general public, unless a disaster strikes, such as a stroke or an aneurysm. Yet, good blood flow is absolutely essential to the brain’s health. This is one reason I favor brain SPECT as our primary imaging study. It specifically looks at blood flow patterns in the brain.
Blood brings oxygen, sugar, vitamins and other nutrients to the brain and takes away carbon dioxide and other toxic waste products. Anything that limits blood flow prematurely ages all of your body’s organs. Consider the skin of smokers. Most people can tell if someone is a smoker by looking at his or her skin. A smoker’s skin is more likely to be deeply wrinkled, and even perhaps tinged with yellow or grey color. Why? Nicotine in cigarettes is a powerful constrictor of blood flow to every organ in the body, including the skin and the brain, as such you look and think older than you are.
Unless you actively do something to change it, blood flow throughout your body decreases over time, especially to the brain. Blood vessels become droopy and blood pressure rises, limiting blood supply. In order to stay young of heart and mind, it is essential to understand the factors that limit blood flow and eliminate them. Improving blood flow is literally the fountain of youth.
Whatever is good for your heart is good for your brain. Since I wrote my book, Sex On The Brain, I also realized that whatever is good for your heart is good for your brain is also good for your genitals. Blood flow to your genitals is essential for both men and women to have healthy, passionate, satisfying sex lives. Did you know that 40% of 40 years olds have erectile (blood flow) dysfunction? And, 70% of 70 year olds have erectile dysfunction, too? No wonder commercials for Cialis, Levitra, and Viagra are everywhere. The startling statistics for erectile dysfunction are an indication that heart and brain problems are also much more common than most people think.
Here is a partial list of factors that limit or disrupt blood flow.
Stress – the overflow of the stress chemical adrenaline constricts blood flow to many areas of the body.
Caffeine – directly constricts blood flow to the brain, disrupts sleep and is involved in dehydration. Ø Nicotine – constricts blood flow everywhere.
Dehydration – the brain is 80% water. Anything that dehydrates you makes it harder to think. I once did a scan of a famous body builder. His scan looked like he was a dug addict, but he vehemently denied it. Then I learned that he significantly dehydrates himself before photo shoots to look leaner for the camera, which was the day after his first scan. When he was adequately hydrated the following week, his brain looked much better.
Artery Disease/Heart disease – directly limits blood flow.
Diabetes – is a small blood vessel disease, limiting blood flow, making blood vessels brittle, and preventing healing of damaged tissue.
Environmental toxins – poison blood vessels.
Lack of sleep – people who get less than 6 hours a sleep at night have lower overall blood flow to the brain.
Lack of exercise – weakens the heart pump, plus blood vessels become droopy and less efficient.
Drug or alcohol abuse – directly toxic to the vascular system. Drug or alcohol show a toxic Swiss cheese appearance on scans from the overall decreased blood flow.
To increase healthy blood flow throughout your body and brain you need to get enough sleep, drink plenty water and avoid substances that dehydrate you, such as caffeine, stop any medications or bad habits like smoking that may be getting in the way and consider taking supplements such as fish oil, gingko and ginseng that boost blood flow.
Probably the most important thing to do is to eliminate any toxins and exercise.
