Positive thinking: Reduce stress by eliminating negative self-talk

Positive thinking helps with stress management and can even improve your health. Practice overcoming negative self-talk with examples provided.

By Mayo Clinic staff

Is your glass half-empty or half-full? How you answer this age-old question about positive thinking may reflect your outlook on life, your attitude toward yourself, and whether you’re optimistic or pessimistic — and it may even affect your health.

Indeed, some studies show that personality traits like optimism and pessimism can affect many areas of your health and well-being. The positive thinking that typically comes with optimism is a key part of effective stress management. And effective stress management is associated with many health benefits. If you tend to be pessimistic, don’t despair — you can learn positive thinking skills. Here’s how.

Understanding positive thinking and self-talk

Positive thinking doesn’t mean that you keep your head in the sand and ignore life’s less pleasant situations. Positive thinking just means that you approach the unpleasantness in a more positive and productive way. You think the best is going to happen, not the worst.

Positive thinking often starts with self-talk. Self-talk is the endless stream of unspoken thoughts that run through your head every day. These automatic thoughts can be positive or negative. Some of your self-talk comes from logic and reason. Other self-talk may arise from misconceptions that you create because of lack of information.

If the thoughts that run through your head are mostly negative, your outlook on life is more likely pessimistic. If your thoughts are mostly positive, you’re likely an optimist — someone who practices positive thinking.

The health benefits of positive thinking

Researchers continue to explore the effects of positive thinking and optimism on health. Health benefits that positive thinking may provide include:

It’s unclear why people who engage in positive thinking experience these health benefits. One theory is that having a positive outlook enables you to cope better with stressful situations, which reduces the harmful health effects of stress on your body. It’s also thought that positive and optimistic people tend to live healthier lifestyles — they get more physical activity, follow a healthier diet, and don’t smoke or drink alcohol in excess. Read the entire article here.

Negative thoughts ‘make you ill’

Sad thoughts could cut your immunity

Having negative thoughts really could make you more illness-prone, say scientists.

A study in the journal Proceedings of the National Academy of Sciences links “negative” brain activity with a weakened immune system.

Researchers from the University of Wisconsin-Madison studied people with high levels of brain activity in a region linked to negative thoughts.

Those with the highest activity levels responded worse to a flu vaccine.

Scientists already knew that pessimists – people rated as more sensitive to negative events – show more activity in a part of the brain called the right pre-frontal cortex.

More activity in the left pre-frontal cortex is linked to positive emotional responses.

Happy thoughts

Dr Richard Davidson, who led the research, studied 52 people aged between 57 and 60. Each of them was asked to recall one event which made them feel very happy, and one which left them feeling sad, afraid or angry. Emotions play an important role in modulating bodily systems that influence our health. The electrical activity in these parts of the brain was measured to check whether their left or right pre-frontal cortex was more active. Afterwards, each volunteer was given a standard flu vaccine shot.

Vaccines work by eliciting an immune response which should hopefully persist and help the body tackle a genuine infection threat if it should arrive. Each research subject was tested over the following six months to gauge the success of the vaccine by measuring the levels of antibodies generated by the vaccine. Those who had shown the most powerful right pre-frontal cortex activity also had the worst immune reactions.

The reverse was true for those who had the most powerful reactions in their left pre-frontal cortex, the side associated with happy reactions.

Dr Davidson said: “Emotions play an important role in modulating bodily systems that influence our health.

“We turned to the brain to understand the mechanisms by which the mind influences the body.”

5 Ways Pets Can Improve Your Health

By Jeanie Lerche Davis

A pet is certainly a great friend. After a difficult day, pet owners quite literally feel the love.

In fact, for nearly 25 years, research has shown that living with pets provides certain health benefits. Pets help lower blood pressure and lessen anxiety. They boost our immunity. They can even help you get dates.

“The old thinking was that if your family had a pet, the children were more likely to become allergic to the pet. And if you came from an allergy-prone family, pets should be avoided,” says researcher James E. Gern, MD, a pediatrician at the University of Wisconsin-Madison, in the Journal of Allergy and Clinical Immunology.

However, a growing number of studies have suggested that kids growing up in a home with “furred animals” — whether it’s a pet cat or dog, or on a farm and exposed to large animals — will have less risk of allergies and asthma, he tells WebMD.

In his recent study, Gern analyzed the blood of babies immediately after birth and one year later. He was looking for evidence of an allergic reaction, immunity changes, and for reactions to bacteria in the environment.

If a dog lived in the home, infants were less likely to show evidence of pet allergies — 19% vs. 33%. They also were less likely to have eczema, a common allergy skin condition that causes red patches and itching. In addition, they had higher levels of some immune system chemicals — a sign of stronger immune system activation.

“Dogs are dirty animals, and this suggests that babies who have greater exposure to dirt and allergens have a stronger immune system,” Gern says.

Date Magnets

Dogs are great for making love connections. Forget Internet matchmaking — a dog is a natural conversation starter.

This especially helps ease people out of social isolation or shyness, Nadine Kaslow, PhD, professor of psychiatry and behavioral sciences at Emory University in Atlanta, tells WebMD.

“People ask about breed, they watch the dog’s tricks,” Kaslow says. “Sometimes the conversation stays at the ‘dog level,’ sometimes it becomes a real social interchange.”

Dogs for the Aged

“Studies have shown that Alzheimer’s patients have fewer anxious outbursts if there is an animal in the home,” says Lynette Hart, PhD, associate professor at the University of California at Davis School of Veterinary Medicine.

“Their caregivers also feel less burdened when there is a pet, particularly if it is a cat, which generally requires less care than a dog,” says Hart.

Walking a dog or just caring for a pet — for elderly people who are able — can provide exercise and companionship. One insurance company, Midland Life Insurance Company of Columbus, Ohio, asks clients over age 75 if they have a pet as part of their medical screening — which often helps tip the scales in their favor.

5 Steps to a Healthy Heart with Acupuncture

Heart disease includes conditions affecting the heart, such as coronary heart disease, heart attacks, congestive heart failure, and congenital heart disease. Despite dramatic medical advances over the past fifty years, heart disease remains a leading cause of death globally and the number one cause of death in the United States. By integrating acupuncture and Oriental medicine into your heart healthy lifestyle, you can dramatically reduce your risk of heart disease.

Taking small steps to improve your health can reduce your risk for heart disease by as much as eighty percent. Steps to prevention include managing high blood pressure, quitting smoking, maintaining a healthy weight, reducing stress and improved sleep – all of which can be helped with acupuncture.

1. Manage High Blood Pressure

High blood pressure makes the heart work harder, increasing its oxygen demands and contributing to angina. This excessive pressure can lead to an enlarged heart (cardiomegaly), as well as damage to blood vessels in the kidneys and brain. It increases the risk of heart attacks, stroke and kidney disease.

Acupuncture has been found to be particularly helpful in lowering blood pressure. By applying acupuncture needles at specific sites along the wrist, inside the forearm or in the leg, researchers at the Susan Samueli Center for Integrative Medicine at the University of California, Irvine, were able to stimulate the release of opioids, which decreases the heart?s activity and thus its need for oxygen. This, in turn, lowers blood pressure.

2. Quit Smoking

Most people associate cigarette smoking with breathing problems and lung cancer. But did you know that smoking is also a major cause of coronary artery disease? In fact, about twenty percent of all deaths from heart disease are directly related to cigarette smoking.

Acupuncture has shown to be an effective treatment for smoking. Acupuncture treatments for smoking cessation focus on jitters, cravings, irritability, and restlessness; symptoms that people commonly complain about when they quit. It also aids in relaxation and detoxification.

3. Maintain a Healthy Weight

Obesity is associated with diabetes, high blood pressure and coronary artery disease, all of which increase the risk of developing heart disease, but studies have shown that excess body weight itself (and not just the associated medical conditions) can also lead to heart failure. Even if you are entirely healthy otherwise, being overweight still places you at a greater risk of developing heart failure.

Acupuncture and Oriental Medicine are an excellent adjunctive tool when it comes to losing weight. They can help to energize the body, maximize the absorption of nutrients, regulate elimination, control overeating, suppress the appetite, and reduce anxiety.

4. Reduce Stress

Stress is a normal part of life. But if left unmanaged, stress can lead to emotional, psychological, and even physical problems, including heart disease, high blood pressure, chest pains, or irregular heart beats. Medical researchers aren’t sure exactly how stress increases the risk of heart disease. Stress itself might be a risk factor, or it could be that high levels of stress make other risk factors worse. For example, if you are under stress, your blood pressure goes up, you may overeat, you may exercise less, and you may be more likely to smoke.

Numerous studies have demonstrated the substantial benefits of acupuncture in the treatment of stress, anxiety and mental health. In addition to acupuncture, Oriental medicine offers a whole gamut of tools and techniques that can be integrated into your life to keep stress in check. These tools include Tui Na, Qi Gong exercises, herbal medicine, dietary therapy, meditations and acupressure that you can administer at home.

5. Improve Sleep

Poor sleep has been linked with high blood pressure, atherosclerosis, heart failure, heart attacks, stroke, diabetes, and obesity. Researchers have shown that getting at least eight hours of sleep is needed for good heart health and getting less than eight hours of sleep can put you at a greater risk for developing heart disease.

Acupuncture has shown great success treating a wide array of sleep problems without any of the side effects of prescription or over-the-counter sleep aids. The acupuncture treatments for problems sleeping focus on the root disharmony within the body that is causing the insomnia. Therefore, those who use acupuncture for insomnia achieve not only better sleep, but also an overall improvement of physical and mental health.

Study Shows Acupuncture Significantly Lowers Blood Pressure

A German study published in the journal Circulation, found that acupuncture significantly lowers both systolic and diastolic blood pressure. The extent of the blood pressure reductions by acupuncture treatments was comparable to those seen with antihypertensive medication or aggressive lifestyle changes, including radical salt restrictions.

For the study, 160 outpatients with uncomplicated, mild to moderate hypertension were randomized to six weeks of acupuncture performed by Oriental medicine practitioners or to a sham procedure. Patients underwent 22 sessions, each 30 minutes in length. By the end of the six weeks, 24 hour ambulatory systolic and diastolic blood pressures were significantly reduced from baseline in the acupuncture treated patients (5.4 mm Hg and 3.0 mm Hg, respectively). No significant changes were seen in the sham acupuncture group.

After six months the blood pressure reductions disappeared, leading investigators to conclude that ongoing acupuncture treatments would be required to maintain the blood pressure reductions. Read the entire article here.

Heal Your Body With Yoga

There’s a good reason you feel like goddess when you walk out of yoga class, and it’s not because you finally got your money’s worth out of your gym. It’s because yoga and similar mind-quieting methods have the potential to work as well as many medications at treating what ails you.

“We now have compelling scientific proof that the mind can heal the body,” says Herbert Benson, M.D., director emeritus of the Benson-Henry Institute for Mind Body Medicine at Massachusetts General Hospital and author of Relaxation Revolution.

The latest promises:

Your Body Dials Down Stress

Dr. Benson’s research has found that mind/body practices—meditation, yoga, tai chi, deep breathing, visualization—all elicit the relaxation response, quelling the release of stress hormones cortisol and adrenaline. Your heart slows, blood pressure falls and digestion eases.

Your Immunity Soars

The relaxation response causes cells to release micropuffs of nitric oxide, a gas that dilates blood vessels and stabilizes the immune system, Dr. Benson reported in Medical Science Monitor. Mind/body methods worked as well as drugs designed to do the same thing, without the side effects.

Your Brain Grows

As you get older, your brain begins to shrink. But in a study in NeuroReport, researchers discovered that the prefrontal cortex and the anterior right insula, areas linked to attention and sensory processing, were thicker and more robust in those who meditate.

“It’s like exercise for the brain, making it stronger,” says Rick Hanson, Ph.D., a neuropsychologist in San Rafael, California, and author of Buddha’s Brain.

Your Genes Change

Here’s the real slap-your-forehead news: In a study in PLoS ONE, Dr. Benson compared the genes of 38 people, half of whom meditated regularly and half of whom never did. Controlling for other factors, he found that genes associated with stress-related illness behaved differently in the two groups.

“These genes control not only stress but also premature aging and inflammation,” he says. It seems meditators’ genes were essentially telling their body to stress less and age more slowly.

Despite the powerful evidence, 45 percent of you remain skeptical of mind/body medicine, according to a Self.com poll, and two percent say it’s out-and-out baloney. Read on and we guarantee you’ll change your mind—and your body, too.

Your Relaxation Rx

Which mind/body treatments have the most rock-solid science backing them up? Brent Bauer, M.D., director of the Complementary and Integrative Medicine Program at the Mayo Clinic in Rochester, Minnesota, provides the big picture.


For… Try…

 

 

The #1 Health Habit You’re Not Doing… Yet

Only 13 percent of SELF readers meditate regularly, but two thirds of you say you’d be willing to give it a try. What’s holding you back? Avoid your biggest roadblocks to inner peace and find your way om.

Roadblock 1: “I don’t know how.”

29 percent of you merely need instruction, so here goes: Pick something simple and recurring to focus on, a mantra. “It could be your breath, a prayer or a saying, like, ‘May this be a good day,’” says Hanson, who teaches meditation. Then repeat it in your head as long as you can, up to 20 minutes. “If you get distracted, that’s OK,” he says. Gently refocus until the mantra has recaptured your attention.

Roadblock 2: “I have no time.”

Stop everything to do nothing? No can do, say 18 percent of you. Luckily, you may get benefits from meditating for as little as five minutes. If even that’s a stretch, you can reduce stress simply by doing daily chores more mindfully.

“Staying steadily, attentively present with everyday tasks such as doing the dishes or brushing your teeth can be a calming, informal kind of meditation,” Hanson says.

Roadblock 3: “I can’t sit still.”

Patience is the issue for 36 percent of you. Instead of fostering a quiet mind, meditation sets off a mental ticker tape of to-do and should-have-done lists. If you’re a fidgety or anxious type, try a walking meditation, Hanson says.

As you stroll, focus on the sensation of breathing or on your footfalls. Walking not active enough? Yoga, tai chi and jogging can all elicit the relaxation response.

Breathing Lessons

There may be no quicker way to trigger the magical relaxation response (and all the good genetic changes that come with it) than by controlling your breath.

Not only will deep breathing lower your blood pressure, but recent research shows sucking wind, as it were, can also increase antioxidant levels in your blood, helping protect you from oxidative stress and all the dastardly conditions associated with it, including heart disease, hypertension, Alzheimer’s disease and plain ol’ aging.
