How exercise helps reduce stress
By:
Lisa Zeigel
 Most of us know about the long list of good things that exercise can do for us. High on that list is stress management. It is easy to forget about that since so much attention is given to the calorie-burning aspects of exercise and its subsequent impact on weight loss, but given that stress is such a killer and is so prevalent in our lives nowadays, it would certainly be beneficial to find out how we can use exercise to help with the challenges brought on by stress in our lives.
How does exercise actually work to relieve stress? Let’s examine a few ways:
Neurological mechanisms
It is ironic that exercise is such a powerful stress-reliever since it is in itself a form of stress – physical stress, but stress nonetheless. But, of course, these are powers that are used for good; not evil. The stress that aerobic exercise exerts upon the body is usually mild, but it is enough to stimulate a protective mechanism whereby proteins are generated from the brain, through a substance called BDNF (Brain-derived Neurotropic Factor) to help the nervous system create new neurons, even repair them.1 Aerobic exercise can also strengthen neural connections – all of which can mean improved memory, cognition, and a restorative effect upon lost or injured neurons – significant for those who suffer from Alzheimer’s and Parkinson’s diseases and other neurological conditions.
Mood chemistry
Exercise is well-known for being a mood-lifter. One of the means by which this occurs is again, through BDNF, which can generate neurons to help build the areas of the brain that can affect depression, and maintains a positive balance of serotonin (low levels of this neurotransmitter are associated with depression). In animal trials, the combination of antidepressants and activity resulted in a higher production of BDNF, so further study in humans would seem logical.
And then there are those famous endorphins, a self-generated painkiller that kicks in after a certain amount of aerobic exercise. Released from the pituitary gland, they block the pain receptors. Because of this, it is theorized that serotonin uptake is heightened, so exercisers may feel a euphoric sensation, also known as the “runner’s high.”
There is yet another mood-lifting chemical that is produced by the body and thought to be positively affected by exercise. That is Phenylethylamine (which is converted into Phenylacetic acid by an enzyme).1 Low levels of these substances are also associated with depression, and in one study conducted in the U.K., researchers found that exercise that was perceived as “hard” by the participants increased these substances after the workout session. It is thought that this may be a more likely reason for the “runner’s high” as Phenylethylamine and Phenylacetic acid are able to cross the “blood brain barrier” in the body, unlike endorphins.
Emotional rescue
Just as we use substances that we know are not good for us to somehow help us deal with the stress and difficulties in life (think food, nicotine, alcohol, etc.) so can exercise be used, but in a much more positive, productive way. It is possible to condition yourself to say go for a walk, instead of reaching for that carton of ice cream in the freezer, when you feel bored at home. The more you practice this behavior, the more it will become a habit. You will be rewarded with knowing that you can solve your boredom and have a longer-term reward that makes you feel good afterwards – instead of a short-term reward that you feel bad and guilty about in the long-run (that ice cream).
Escape time or brain time
There are a couple of other ways you can use your time exercising to help you get through those tough problems. Some people like to use their time on the treadmill to just “zone out” and get into the feeling of the movement, or they watch television, listen to some motivational music, chat with a workout partner, or even read. You can even lose yourself in your weight-lifting session as you are concentrating on performing the exercises correctly or in a class, where you have to pay attention to what the instructor is teaching so you can follow along.
Sometimes the time you take to exercise can get you away from workplace distractions and can be a productive time to think and plan. The rhythmic movement of cycling or running can create a peaceful environment for your mind, where you can think things through and create solutions, innovations, or anything you want!
There is no doubt that if you ask regular exercisers what makes them stick with it, most people will mention, among other things, the stress relief, and the feel-good aspects. It has certainly saved me tons of money compared to going to therapy or taking medication. In fact, more physicians and counselors are prescribing exercise over meds for those with mild depression. Isn’t that a “no brainer?”

 Dr. Barry Sears is a leading authority on the dietary control of hormonal response. A former research scientist at the Boston University School of Medicine and the Massachusetts Institute of Technology, Dr. Sears has dedicated his research efforts over the past 30 years to the study of lipids. He holds 13 U.S. Patents in the areas of intravenous drug delivery systems and hormonal regulation for the treatment of cardiovascular disease.
A turning point in his research occurred in 1982. That year, the Nobel Prize in Medicine was awarded for discoveries of the role that specialized hormones, known as eicosanoids, play in the development of cardiovascular disease, diabetes, auto-immune diseases, and cancer. Since eicosanoids are only generated from dietary fat, Dr. Sears reasoned that one could apply intravenous drug delivery principles to nutrition in order to control these exceptionally powerful hormonal responses with laser-like precision. In essence, his approach treats food as if it were a drug.
This area of his research led to various patents in the area of hormonal control by essentially using food as an oral drug delivery system to modulate eicosanoids especially for cardiovascular, diabetic, and neurological patients.
The impact of Dr. Sears’ revolutionary work in the dietary control of hormonal response began with the publication of his landmark book, The Zone. Since its publication in June 1995, The Zone has sold more than 2,000,000 hardcover copies, and became a #1 best seller on the New York Times book list. In addition, The Zone has been translated into 22 languages indicating a worldwide response to Dr. Sears’ research. His second book, Mastering the Zone, published in 1997, also became a New York Times bestseller with hardcover sales in excess of 500,000 copies to date. His third book, Zone Perfect Meals in Minutes, published in 1997, quickly became one of the best-selling cookbooks of 1997 and an another New York Times bestseller. The Anti-Aging Zone was published in 1999 and provides the molecular insights into how the Zone Diet can reverse the aging process. The Omega Rx Zone, published in 2002, explores the molecular foundation of chronic disease and how high-dose fish oil can dramatically reverse it. His latest book The Anti-Inflammation Zone discusses how to combat silent inflammation in order to reduce the risk of cancer, heart disease, diabetes, dementia, and many other inflammatory conditions—and how to reverse these conditions if they are already present. To date more than 5 million hardcover copies of his Zone books have been sold in the United States.
His research has elevated food from more than simply a source of calories to being recognized as an exceptionally powerful drug. Because of his revolutionary research, Dr. Sears has been a frequent guest on many national programs such as 20/20, Today, Good Morning America, CBS Morning News, CNN, and MSNBC.
Dr. Sears continues his ongoing research as President of Zone Labs, a biotechnology company in Danvers, MA as well as the President of the non-profit Inflammation Research Foundation in Marblehead, MA. In addition to continuing research on the hormonal effects of food, Dr. Sears has expanded his research in developing innovative dietary approaches to treating cancer and neurological conditions, as well as his on-going work in treating cardiovascular diease and type 2 diabetes.

I have been taking the Fish Oil for over 3 years now. I am 44 playing hockey and working out. The Fish oil helps with the pain that I get from playing hockey. It greatly enhances my performance on the ice and while working out. I have noticed a big difference in my energy, attentiveness and memory. If I miss a day for whatever reason, I notice a huge difference and it feels like something is missing. Anyway that is my short little story and it comes from the heart.
– Carter B.
I am a nutritionist and Ph.D. doctor of health and nutrition. For Dr. Sears to figure out balancing fat, carbs and protein, is really beyond brilliant. It is a milestone in diet history. I go over people's diet/emotional journals. Mostly all the time, we discover that the fatigue, irritability, unstable emotions were due to the imbalance in their diet. Using the Zone to balance them out, helps control weight, roller coaster emotions and gives them energy. Dr. Sears is so right when he says food is medicine. He has figured out the most powerful drug combination going, called The Zone.
Best and healthy wishes,
– Elaine W., Ph.D., N.C., M.A.
I have a very exhausting job as a flight attendant. I read the "Omega Rx Zone" about 4 years ago and started taking the fish oil. I am 47 and have been flying for 22 years. I am very active, I run and lift weights. But combining lack of regular sleep, a physically demanding job, and irregular eating patterns this job takes a toll on the body. Since taking the fish oil, I have noticed that I do not get exhausted. I get tired, but not exhausted. I stopped taking it for a couple of months and then started taking another company's fish oil. I started getting exhausted again. I came back to Zone Labs and will continue with the fish oil for the rest of my life. I believe in the product and it makes a huge difference in my life. It makes a difference with my running as well. I also bring the bars and shakes with me on the road. It is almost impossible to eat the way I should at work. I haven't found the right secret. At least I have my Zone fish oil, bars, and shakes.

I have been in the Zone, for about 1 month now. I wanted to share with you how wonderful I think this program is. I have been a personal trainer for almost 10 years and actively compete in numerous athletic activities. The Zone program has helped me to achieve a better awareness of my nutritional needs and the results I have seen are amazing! I have lost nearly 13 lbs since I have been in the Zone. I feel more mentally alert, more focused at work, have greater intensity during my training, have made significant strength gains, and just feel better over all. With that said, I would like to thank you for helping me in my quest for "super-health"!
Thank you!
– Rob Y.
I read 'The Zone' and as exactly as I could followed the advice for diet. I noted weight loss progress. Over six months, I lost 33 pounds. One year has passed since then. I have maintained the new weight, guided always by Zone concepts. The Zone is powerful - I have found it fantastic and I am very grateful to Dr Sears.
– Lyn S.
Before I stumbled across the Zone I was weighing close to two hundred pounds and I was depressed. I used to be a gymnast as a young man. I would think, "look at me now," when I looked in a mirror. The day I found 'The Zone' book, I was intrigued and as I read it the science made sense and so, I began to follow the "treatment". I began to lose weight and I was feeling way more energetic. I am forty two years old, I am very active and my weight is down to 162 lbs, 38 pounds lost on the Zone. I cycle, walk, jog, swim and I can now perform some of the more simple gymnastic skills I did twenty years ago...I literally feel like I have turned back the clock.
Thank you!
– Jack J.
I have been on the Zone diet for 7 years. I did not go on the diet to lose weight necessarily; but fairly quickly I lost 25 pounds, going from 190 to 165; from a 36-inch waist to a 32-inch waist. I primarily did the Zone to live healthier. My health is excellent now. I just turned 62 years old. My Zone is my eating lifestyle now; I seldom stray; and I do not miss anything. It is The Good Life.
– Curtis Y.
My wife's doctor told her to read "Enter the Zone" and to do the diet, so I told her I would do it with her. After only one week on the plan we went on a strenuous hike (the first of the year), and when we stopped at our favorite coffee shop on the way home I was able to get out of the car and stand upright and walk into the place without pain or stiffness. The Zone had eliminated all the inflammation that had always forced me to stumble all humped over into the coffee shop any time we skied or hiked all day.
Thank you, Doctor Sears.
– Larry C.
I used to have a lot of knee pain when I walked or ran. I have been taking Omega Rx for almost a year now, and rarely have any pain. I believe it is the anti-inflammation action of the oil. I feel smarter as well. Thanks for developing such a superior oil!
– Joe W.
Prior to following the Zone Diet, my body fat was around 15% and my weight around 153 pounds. No matter what I did, my weight and body fat did not change much. I regularly cycled 20-30 hours per week logging well over 400 miles. That had little impact on body fat or weight. Diet also seemed to have little impact on body fat or weight. Within a couple of months of following the zone diet, my weight dropped rather quickly to 142 pounds and body fat to about 8%. I still regularly cycle up to 20 hours per week (during the summer). I have also started strength training. I eat about 16 blocks per day. I take 3.6 grams of fish oil per day, along with Vitamin E, Alpha Lipoic Acid, CoQ10, and B & C vitamins. I also take GLA, which in my opinion, has significantly reduced fatigue and improved recovery times after exercise.

All polyphenols have antioxidant properties than can be measured by their Oxygen Radical Absorption Capacity (ORAC), but not all polyphenols have anti-inflammatory properties. The polyphenols in Dr. Sears’ Zone Polyphenol Plus have been carefully chosen to have both.
Polyphenols are the phytochemicals that not only give fruits and vegetables their color, but also help regulate inflammation. In addition, polyphenols also activate the key enzyme (AMP kinase) that helps restore cellular ATP levels. Polyphenols also help regulate the activation of inducible inflammatory proteins (such as COX-2 and inflammatory cytokines).
There are more than 4,000 known polyphenols, and the richest sources are fruits and vegetables. In general, the more color a fruit or vegetable has, the richer the polyphenol content.
