China has become the first country to genetically modify genes and insert them back into a human body. The test patient is suffering from aggressive lung cancer. They were able to extract genes that they believe will effectively attack the cancer if they are in high enough numbers. No final results have been released on the study, but it is a huge milestone in the research field. China is not the only country working on the technology, and the first to complete it would be looking at huge profits.
"The modified cells were then multiplied and re-introduced into the patients' bloodstream where, it is hoped, they will home in on the cancer and wipe it out."

What Are the Health Benefits of Flax Seed Oil
October 27, 2012 06:30 PM
Flex seed oil is highly beneficial for our general well-being. It features a high-volume of omega-3 fatty acids and offers untold curative and preventive health benefits. Several of the contained nutrients consist of carotene, vitamin E and unsaturated alpha linolenic acid.
Flax oil is highly beneficial for several different systems and areas of the body, from the cardiovascular system, immune system, reproductive system to the nervous system and joints. Certain acids in the oil help with preventing the onset of artery clots and lowering the level of cholesterol. This oil is also appreciated for its ability to speed up the healing process from knocks or sprains, improves the metabolism, and helps with improving color perception and vision.
Here are some of the main benefits to taking a supplement of flax seed oil -
Lowers the Risk of Heart Disease
Flax oil offers the ability to cut the chance of suffering from heart disease, mainly due to its effectiveness at reducing the possibility of the blood platelets sticking together. Flax is also efficient at promoting the health of the blood vessels. Lower blood pressure is achieved due to the active ingredient of Omeg-3 fatty acid.
Can Reduce the Risks of Certain Cancers
It has been reported the taking flax seed oil has the potential to reduce the development of certain cancers, such as breast cancer. Action ingredients, such as lignans (antioxidants) and omega-3 help with preventing cancer.
Helps to Prevent Dry Eyes
A supplement of flax seed is also highly effective at stopping itchy dry eyes. Dry eyes are often as a result of not having sufficient oil in the protective tear film. If a shortage of oil becomes noticeable, the chance of water evaporating from the eyes surface is greatly increased. Supplements containing omega-3 will help with reversing this effect, by ensuring the oil glands have sufficient oil to cover the eye.

The eyebright plant is elegant and small, growing between two and eight inches high. This plant is an annual, commonly growing on heaths and other dry pastures, especially on chalky soil. The plant flowers from July to September and has deeply cut leaves and small, white or purplish flowers. The stem is erect and wiry. It comes in either unbranched, small specimines, or with many opposite branches. The leaves are tiny, about 1/6 to ½ inches in length and opposite to one another on the lower portion of the stem. The flowers, which are white or lilac, have purple veins and terminal spikes. The structure of the flower places the plant in the Scrophulariaceae family. The seeds in this flower are produced in tiny, flattened capsules, and are numerous and ribbed.
When a bee visitor comes in search of the honey lying around the ovary at the bottom the petal tube, it knocks against the anther spurs, setting the pollen free so that it falls on the insect’s head. When visiting the next flower, the bee will then rub its head against the outstanding stigma, in which cross-fertilization takes place.
The eyebright plant has white petals that have a red or purple tinge, resembling bloodshot eyes. It is this appearance that is thought to be the reason for the use of eyebright in treating eye irritations as far back as the Middle Ages. Topical applications of this herb were prescribed by Dioscorides and Theophrastus for eye infections.
The eyebright plant will not grow readily in a garden if it is transplanted unless it is protected by grass. The reason for this is that it is a semi-parasite and relies on its nourishment on the roots of other plants. Above ground, the plant appears to be a perfectly normal plant, with flowers and bright green leaves. But below the surface, suckers from its roots spread around and lie on the rootlets of the grass plants surrounding it. The grass preyed upon does not suffer very much. The eyebright plant, being an annual, renews itself each year. For centuries, eyebright has been the herb of choice for treating eye irritations. It is extremely helpful in conditions that involve the mucous membranes. This herb can help to relieve eye irritations or eyestrain when used as eyewash. The herb’s antiseptic properties allow it to help fight eye infections. Traditional uses of eyebright include eye problems such as failing vision, eye inflammation, eye ulcers, conjunctivitis, and eyestrain. This herb is able to strengthen all parts of the eye and provide elasticity to the nerves and optic devices that are essential for sight. Additionally, eyebright is stimulating to the liver, as it helps cleanse the blood.
The entire eyebright plant is used to provide alterative, anti-inflammatory, antiseptic, astringent, bitter, and stimulant properties. The primary nutrients found in this herb are copper, iodine, iron, silicon, vitamins A, B, B-complex, C, D, and E, and zinc. Primarily, eyebright is extremely beneficial in dealing with blood impurities, cataracts, colds, conjunctivitis, eye disorders and infections, eyestrain, and glaucoma.
Additionally, this herb is very helpful in treating black eyes, sinus congestion, coughs, hay fever, headaches, hoarseness, memory loss, and sties. For more information on the many beneficial effects provided by this herb, please feel free to contact a representative from your local health food store.
Natural Remedies For Bumps, Bruises, Scrapes, and Insect Bites
November 10, 2007 09:52 AM
Whether you are a child or an adult you are as susceptible to the damage done to skin and soft tissue by hard activities as anybody else. So what can you look for if you decide have a day outdoors and face the dangers that you will come across that want to leave you bruised ,scratched, scraped, cut and itching from all the falls, knocks, stings and bites that most people experience when they are more used to spending their time indoors?
Bruises are caused by a knock, and can happen without you even being aware of it. The blood vessels get damaged and leak. If you notice it right away, you can lessen the degree of bruising by applying ice or cold water to constrict the capillaries and cut down the flow of blood leaking from them. Some people bruise easier than others, and excessive bruising for no apparent reason could be a symptom of a more serious underlying condition and you should see your doctor.
A bump, or lump, can appear for many reasons, but generally settles down after a while. It can simply be the body's reaction to a hard knock that did not damage the blood vessels, but prompted a natural swelling to protect the area. They can also be caused by insect bites. You don’t always see these little pests – they have lunch then zip off without you even being aware of it until the area begins to itch and swell. However, if you have a lump under the armpit, in your neck or behind your ears it could be a swollen gland and you should contact your physician.
Everybody gets minor scrapes now and again, and when you spend any time outside you can get bitten by insects such as mosquitoes, midges, blackflies, horse flies – you name it, they will lunch on you as on any other animals. You can also get stung by vegetable nasties, though if you do then look around for a remedy. Strangely, many stinging plants have another plant close by that can be used as a remedy. This is likely because, after being stung, people just rubbed whatever was handy on the area and eventually these remedies were discovered.
Thus, dock leaves are often found beside nettles, and touch-me-not beside poison ivy. These are good natural remedies for stings caused through contact with these particular plants, and there are many other natural remedies that can be used for the other everyday hurts that people receive just for carrying out normal activities outside in a natural environment. Let’s have a look at some of the natural remedies that people have used through the ages, and that are still used to this day, even in proprietary creams and salves.
Calendula, or marigold, is very effective in relieving skin irritations and inflammation. It can be applied topically to relieve the symptoms of bruises, cuts and scrapes, and also for the initial treatment of burns and scalds. It has anti-inflammatory properties and can be used on inflamed or infected cuts and skin lesions. These properties are believed to be due to the high level of flavonoids found in calendula that have anti-oxidant properties and help the immune function to do its work. Among these is the powerful Quercetin with its strong anti-histamine properties.
It also appears to possess anti-viral properties, though the reason for this is not clear and is still under investigation. Marigold also contains carotenoids and triterpene saponins, both of which will contribute to the medicinal effects. The dried flowers or leaves, or the fresh flowers, can be used and it is an old adage that pus will not form where marigold is used. It is also good for the treatment of insect bites and boils, where it appears to either prevent infection or clear up any that are there. It has also been proven to prevent the seeping of blood from the capillaries in scrapes, and to promote blood clotting.
Calendula was used during the First World War by British doctors to dress wounds and prevent infection. A dressing steeped in a mild solution of calendula extract was enough, and it likely saved many lives.
Another plant with similar properties is the alpine Arnica, which is useful to reduce the swelling and pain of bruises. It works simply by rubbing the leaves on the area when you have a fall or a hard knock. The active ingredients here are again flavonoids, and sesquiterpene lactones along with tannins, carotenoids and thymol. These, along with the flavonoids, stimulate the circulation and carry away any fluids trapped in bruises and swellings.
The sesquiterpene lactones act as anti-inflammatories and boost the immune system, helping to reduce swelling and pain. In fact terpenoid chemicals are common to many of the herbs and flowers that have found a use in the relief of pain in swelling and bruises. The same is true of Ledum, better known as Rosemary, traditionally used for the treatment of burns, ulcers dandruff, and dry skin and to get rid of lice among many other internal and topical applications.
The active ingredients of rosemary (ledum) include mono-, di- and triterpenes and also the ubiquitous flavonoids and camphor and linalool. If you wash down burns, grazes and cuts with a wash of ledum extract, then you will protect the patient from infection at the time when they are most vulnerable to infectious agents.
Hypericum has uses as an anti-inflammatory and antiseptic, and is therefore useful for exactly the same conditions as all of the above. It also has astringent properties, so that like Calendula, Hypericum can be used to prevent the capillary seepage that frequently leads to infections. The active ingredients here are apparently flavonoids again, with their antiseptic and anti-inflammatory properties.
Considering that they are among the most common antioxidants and anti-inflammatory agents in the plant world; it is no coincidence that flavonoids just happen to be contained in the vast majority of natural treatments for scratches, grazes and bruises. They reduce swelling, pain and inflammation, and also act as antiseptics by disrupting the cell walls of bacteria.
Hypericum is well known by its alternative name St. John’s Wort, where it is used in the treatment of depression. However, the active ingredients here are mainly hyperforin and hypericin, which have little to do with the topical benefits of the plant.
If you have suffered from insect bites and stings, then you would have been thankful had you brought some Apis Mellifica with you. Obtained from bees, this again contains terpenes among many other chemicals, and is used paradoxically in the treatment of bee stings and other insect stings and bites. It’s amazing how many of these old remedies contain terpenes of various types and also flavonoid chemicals. It is useful for most rashes that have raised puffy lumps, such as hives.
Finally, if you manage to stay out without getting any bruises, abrasions, scratches or bites, you will be very lucky. However, if you get sunburn through being out in the sun too long, just look around for some stinging nettle, or Urtica. The leaf contains polysaccharides and lectins that stop the production of prostaglandins in the body that cause inflammation. Your sunburn will ease and you be able to return home relatively symptom free from your day outdoors.
These natural remedies can be hard to find growing naturally due to many factors such as the time of year or your geographical location these herbs may grow in. Alternative sources are available at your local health food store where you can find all the above mentioned herbs in ointments and creams specifically formulated for your needs.
Recognizing the Signs: Roadmap to a Healthy Heart
June 13, 2005 10:06 AM
Recognizing the Signs: Roadmap to a Healthy Heart by Louis McKinley Energy Times, January 2, 2004
From time immemorial, people have tuned into life's lessons that come from the heart. Sadly, times are changing: If you're like most inhabitants of today's harried world, you may be too distracted to detect important clues about your cardiovascular circumstances.
And while heart lessons may be more complicated than simply connecting the physiological dots, understanding those heart messages are imperative for improving and maintaining your heart health.
Every cell in your body relies on heart-powered blood flow to keep it supplied with nutrients, oxygen, hormones and other natural chemicals necessary for survival. Without that supply of life-giving substances, few cells in the body-including those within the heart itself-can survive very long.
And just as damage to a major roadway can cause mayhem with traffic patterns, damage to blood vessels and the heart can wreak a lumpy cardiovascular havoc that blocks the passage of blood and endangers your heart's well-being.
Your Heart Disease Chances
Within the last ten years, scientific research performed by investigators around the world has focused on the specific factors that most strongly influence your chances of developing heart disease and suffering either a heart attack or a stroke.
While much of your risk depends on your genetic inheritance and family history, several factors that determine your heart health are within your control.
The most important factors you can do something about include:
* Smoking: free radicals generated by burning tobacco causes significant damage to blood vessels and other cells
* Lack of exercise: the human body is designed for consistent, moderate physical activity; without exercise, the body slacks off in creating antioxidant protection for arteries
* Diabetes: when excess blood sugar persists, physiological processes begin that endanger the heart and arteries
* Cholesterol: when oxidized (a chemical process that has been compared to a kind of internal rusting), cholesterol can form artery-blocking plaque; antioxidant nutrients like vitamin C and natural vitamin E may help the body limit this process
* High blood pressure: excessive pressure within the blood vessels raises the risk of damage to the heart and arteries; a program of weight loss and exercise can help control blood pressure
* Being overweight: the extra body fat carried around your middle is linked to a greater risk of heart problems
Heart Attack Signs
Do you think you know what a heart attack feels like? Well, if you think it feels like a dramatic pain somewhere in your chest that knocks you to the floor, you're probably wrong. "Most heart attacks do not look at all like what one of my colleagues calls the 'Hollywood' attack-the heart attack you see on television or in the movies," warns Julie Zerwic, MD, professor of surgical nursing who has studied what happens when people develop heart disease and suffer damage to their hearts.
"The symptoms [of heart problems] are not necessarily dramatic. People don't fall down on the floor. They don't always experience a knife-like, very sharp pain. In fact, many people describe the sensation as heaviness and tightness in the chest rather than pain," she says. And, if you're a woman experiencing a heart attack, you may not even feel discomfort specifically in your chest. Instead you may experience a severe shortness of breath. The apparent ambiguity of the discomforts caused by a heart attack lead many people to either ignore them or take hours to realize they need to go to the emergency room at the hospital.
Consequently, much fewer than half of all individuals undergoing a heart attack actually go to a hospital within an hour of the start of the attack. That delay can be a fatal mistake.
"Timing is absolutely critical," laments Dr. Zerwic. "If treatment starts within a hour after the onset of symptoms, drugs that reestablish blood flow through the blocked coronary artery can reduce mortality by as much as 50%. That number drops to 23% if treatment begins three hours later. The goal is to introduce therapy within two hours."
However, in Dr. Zerwic's research, only 35% of non-Hispanic whites go to the hospital within an hour of the start of a heart attack. And among African-Americans, the number of people going to the hospital right away drops to a frighteningly low 13%.
Often, people will lie down or use a heating pad to relieve the tightness they feel in the chest," says Dr. Zerwic. "They may take some medicine and wait to see if that works. All these steps postpone needed treatment."
Signs of a possible heart attack include:
* Chest discomfort: Heart attacks most frequently cause discomfort in the center of the chest that can either go away after a couple of minutes (and come back) or persist. The discomfort may feel like strong pressure, fullness or pain.
* Upper body discomfort: An attack may set off pain or discomfort in either or both arms, and/or the back, neck, jaw or stomach.
* Shortness of breath: Chest discomfort is frequently accompanied by shortness of breath. But it's important to note that shortness of breath can take place even in the absence of chest discomfort.
* Other signs: You can also break out in a cold sweat, or feel nauseated or light-headed.
A Woman's Sleep Signs
If you are a woman who suddenly experiences a marked increase in insomnia and puzzling, intense fatigue, you may be in danger of an imminent heart attack.
In an attempt to understand how women's symptoms of heart problems differ from those of men, researchers talked to more than 500 women in Arkansas, North Carolina and Ohio who had suffered heart attacks. (Technically, what they had experienced is referred to as acute myocardial infarction.)
They found that chest pain prior to a heart attack was only reported by about 30% of the women surveyed.
More common were unusual fatigue, sleep disturbances and shortness of breath (Circulation Rapid Access, 11/3/01).
"Since women reported experiencing early warning signs more than a month prior to the heart attack, this [fatigue and sleep problems] could allow time to treat these symptoms and to possibly delay or prevent the heart attack," says researcher Jean C. McSweeney, PhD, RN, nursing professor at the University of Arkansas for Medical Sciences in Little Rock. In Dr. McSweeney's study, more than nine out of ten women who had heart attacks reported that they had had new, disturbing physical problems more than a month before they had infarctions.
Almost three in four suffered from unusual fatigue, about half had sleep disturbances, while two in five found themselves short of breath.
Other common signs included indigestion and anxiety.
"Women need to be educated that the appearance of new symptoms may be associated with heart disease and that they need to seek medical care to determine the cause of the symptoms, especially if they have known cardiovascular risks such as smoking, high blood pressure, high cholesterol, diabetes, overweight or a family history of heart diseases," says Dr. McSweeney.
Dr. McSweeney warns that, until now, little has been known about signs that women are having heart trouble or heart attacks. The fact that most of Western medicine's past attention has been on heart problems in men has obscured the warning signs in women. As part of Dr. McSweeney's studies, she and her fellow researchers have discovered that more than 40% of all women who suffer a heart attack never feel any chest discomfort before or during the attack.
"Lack of significant chest pain may be a major reason why women have more unrecognized heart attacks than men or are mistakenly diagnosed and discharged from emergency departments," she notes. "Many clinicians still consider chest pain as the primary symptom of a heart attack."
Vitamins for Diabetes and Heart Disease
Having diabetes significantly raises your chance of heart disease, which means that keeping your blood sugar levels under control can reduce your chances of suffering a heart attack.
Today, 17 million Americans have diabetes and, as the country's population in general gains weight and fails to exercise, the number of people suffering this problem continues to grow.
The first line of defense against diabetes consists of exercise and weight control. All you have to do is take a brisk walk for 30 minutes a day to drop your chances of diabetes (American Journal of Epidemiology 10/1/03).
"We have found that men and women who incorporate activity into their lifestyles are less likely to develop type 2 diabetes than those who are sedentary. This finding holds no matter what their initial weight," said Andrea Kriska, PhD, professor of epidemiology at University of Pittsburgh Graduate School of Public Health.
To help your body fight the development of diabetes, researchers also recommend vitamin C and natural vitamin E.
Researchers working with lab animals at the University of California at Irvine have found that these antioxidant vitamins can help insulin (the hormone-like substance secreted by the pancreas) reduce harmful blood sugar. In addition, these vitamins shrink the chances of organ damage that can be caused by diabetes (Kidney International 1/03).
In this investigation, these vitamins also helped reduce blood pressure, another risk factor that raises heart disease risk.
"Blood pressure was lowered to normal, and free radicals were not in sufficient numbers to degrade the sugars, proteins and nitric oxide," notes Nick Vaziri, MD, professor of medicine at the University of California. "We think this shows that a diet rich in antioxidants may help diabetics prevent the devastating cardiovascular, kidney, neurological and other damage that are common complications of diabetes."
Free Radical Blues
Dr. Vaziri and his group of researchers found that untreated diabetes raised blood pressure and increased the production of free radicals, caustic molecules that can damage arteries and the heart. Free radicals can change blood sugar and other proteins into harmful substances, boosting tissue and heart destruction.
In Dr. Vaziri's work with lab animals, he found that treating diabetes with insulin lowered blood pressure and helped keep sugar and protein from changing into dangerous chemicals, but allowed the free radicals to subvert nitric oxide, a chemical the body uses to protect itself from free radicals.
In this investigation, adding vitamins C and E to insulin insulated the body's sugars, proteins and nitric oxide from oxidative assault. This produces a double advantage: Lowering the risk of heart disease and other damage to the body from diabetes.
Maitake, an Oriental mushroom that has been shown to have many health benefits, can also be useful for people with diabetes who are trying to avoid cardiovascular complications. Laboratory studies in Japan demonstrate that maitake may help lower blood pressure while reducing cholesterol (Biological & Pharmaceutical Bulletin 1997; 20(7):781-5). In producing these effects, the mushroom may also help the body reduce blood sugar levels and decrease the risk of tissue damage.
Tobacco smoke is one of the most notorious causes of heart problems. In the same way a hard frost exerts a death grip on a highway, the smoke from cigarettes can freeze up arteries and hamper their proper function. A healthy artery must stay flexible to comfortably allow adequate circulation.
But "...when blood vessels are exposed to cigarette smoke it causes the vessels to behave like a rigid pipe rather than a flexible tube, thus the vessels can't dilate in response to increased blood flow," says David J. Bouchier-Hayes, MD, professor of surgery at the Royal College of Surgeons in Ireland, who has studied the deleterious effects of tobacco.
This rigidity is called endothelial dysfunction. When arteries are rigid, blockages gum up vessels, clots and other impediments to blood flow appear, and your risk of heart attack and stroke increases (Circulation 2001 Nov 27; 104(22):2673).
This condition can also cause chest pain (angina) similar to that caused by a heart attack, and should be evaluated by a knowledgeable health practitioner.
Although all experts recommend you stop smoking to lower your heart disease risk, some studies have found that Pycnogenol(r), a pine bark extract that helps the body fight inflammation, may ease some of smoking's ill effects.
In a study of platelets, special cells in the blood that can form dangerous blood clots, researchers found that Pycnogenol(r) discouraged platelets from sticking together (American Society for Biochemical and Molecular Biology 5/19/98). By keeping platelets flowing freely, this supplement may alleviate some of the heart-threatening clots that tobacco smoke can cause.
In Ayurvedic medicine, a traditional therapy from India, an herb called guggul has also been used to lower the risk of blockages in arteries. This herb, derived from the resin of the mukul tree, has been shown to reduce cholesterol by about 25%. People taking this herb have also reduced their triglycerides (harmful blood fats) by the same amount (Journal Postgraduate Medicine 1991 37(3):132).
The Female Version of Heart Disease
For one thing, women often don't suffer from the crushing chest pain that for most people characterizes a heart attack; instead, many women experience back pain, sweating, extreme fatigue, lightheadedness, anxiety or indigestion, signs that can be easily misread as digestive troubles, menopausal symptoms or indicators of aging.
The genders also differ in how heart disease poses a threat. While men seem most endangered by the buildup of blockages in arteries, women apparently are more at risk from endothelial dysfunction. But more study needs to be done since, in many cases, researchers have been unable to pin down the precise mechanism that causes many women to die of heart disease.
Scientists have found that the number of women in their 30s and 40s who are dying from sudden cardiac arrest is growing much faster than the number of men of the same age who die of this cause. But research by the Oregon Health & Sciences University and Jesse E. Edwards Cardiovascular Registry in St. Paul, Minnesota, shows that while doctors can pinpoint the coronary blockages that kill men, they can't find specific blockages in half of the female fatalities they have studied (American Heart Journal 10/03).
"This was an unexpected finding. However, the study underscores the need to focus on what is causing these younger women to die unexpectedly because the number of deaths continues to increase," says Sumeet Chugh, MD, a medical professor at Oregon.
Since the failure of arteries to relax probably contributes to heart disease in many women, eating red berries, or consuming supplements from berries such as chokeberry, bilberry or elderberry, may be important in lowering women's heart disease risk. These fruits help arteries expand and allow blood to flow freely.
Red berries are rich sources of flavonoids, polyphenols and anthocynanins. The anthocyanins are strong antioxidants that give the berries their color. Research at the Indiana University School of Medicine have found that these chemicals can interact with nitrous oxide, a chemical produced by the body, to relax blood vessels (Experimental Biology conference 5/20/02).
As researchers work to devise lifestyle roadmaps that can steer you around the perils of heart disease, they are finding that exercise is a key path to avoiding cardiovascular complications.
A 17-year study of about 10,000 Americans found that those who exercised and kept their weight down (or took weight off and kept it off) experienced a significantly lower risk of heart problems (Preventive Medicine 11/03).
"The fact is that those who both exercised more and ate more nevertheless had low cardiovascular mortality," says Jing Fang, MD, of the Albert Einstein College of Medicine in the Bronx, New York. Burning calories in physical activity may be the secret to reducing heart disease risk and living longer, she says.
Dr. Fang's research used information collected from the First National Health and Nutrition Examination Survey in 1975 and then computed how much people exercised, how their body mass indices varied and which of these folks died of heart disease during the next two decades.
In the study, more than 1,500 people died of heart disease. Those who worked out and consumed more calories cut their risk of heart disease death in half.
Exercise Is Essential
"Subjects with the lowest caloric intake, least physical activity, and who were overweight or obese had significantly higher cardiovascular mortality rates than those with high caloric intake, most physical activity, and normal weight," Dr. Fang notes. The individuals in the study who were overweight and didn't exercise had a bigger risk of heart disease even if they tried (and succeeded) at eating less.
"This suggests that heart disease outcome was not determined by a single factor, but rather by a compound of behavioral, socioeconomic, genetic and clinical characteristics," according to Dr. Fang.
According to researchers, if your job requires a great deal of physical activity, your health will be better if you get another job. Exercise on the job not only doesn't decrease your risk of heart disease, it may actually raise it. The reason: On-the-job activity is linked to heart-endangering increases in job stress.
Research into this subject, performed at the Keck School of Medicine of the University of Southern California, found that while recreational exercise slowed hardening of the arteries, workers who had to exert themselves during the workday had arteries that were blocked at a younger age (American Journal of Medicine 7/03).
In this study, researchers examined about 500 middle-aged employees as part of what is called the Los Angeles Atherosclerosis Study.
"We found that atherosclerosis progressed significantly faster in people with greater stress, and people who were under more stress also were the ones who exercised more in their jobs," says James Dwyer, PhD, professor of preventive medicine at the Keck School. According to Dr. Dwyer, "This suggests that the apparent harmful effect of physical activity at work on atherosclerosis-and heart disease risk-may be due to the tendency of high-activity jobs to be more stressful in modern workplaces.
"It appears from our findings that the psychological stresses associated with physically active jobs overcomes any biological benefit of the activity itself."
On the other hand, the scientists found that heart disease drops dramatically among those who exercise the most in their spare time. In the study, people who vigorously worked out at least three times a week had the lowest risk. But even those who just took walks enjoyed better heart health than people whose most strenuous activity was working the TV remote. Dr. Dwyer says, "These results are important because they demonstrate the very substantial and almost immediate-within one or two years-cardiovascular benefit of greater physical activity."
Lowering your risk of heart disease is substantially up to you. Listen to what your heart tells you it needs; then, exercise your right to fetch some cardiovascular necessities.
