Health Benefits of Tai Chi: Meditation in Motion

Eventbrite - RESET with Tai Chi

 This gentle form of exercise can prevent or ease many ills of aging and could be the perfect activity for the rest of your life.

Tai chi is often described as “meditation in motion,” but it might well be called “medication in motion.” There is growing evidence that this mind-body practice, which originated in China as a martial art, has value in treating or preventing many health problems. And you can get started even if you aren’t in top shape or the best of health.

In this low-impact, slow-motion exercise, you go without pausing through a series of motions named for animal actions — for example, “white crane spreads its wings” — or martial arts moves, such as “box both ears.” As you move, you breathe deeply and naturally, focusing your attention — as in some kinds of meditation — on your bodily sensations. Tai chi differs from other types of exercise in several respects. The movements are usually circular and never forced, the muscles are relaxed rather than tensed, the joints are not fully extended or bent, and connective tissues are not stretched. Tai chi can be easily adapted for anyone, from the most fit to people confined to wheelchairs or recovering from surgery.

“A growing body of carefully conducted research is building a compelling case for tai chi as an adjunct to standard medical treatment for the prevention and rehabilitation of many conditions commonly associated with age,” says Peter M. Wayne, assistant professor of medicine at Harvard Medical School and director of the Tai Chi and Mind-Body Research Program at Harvard Medical School’s Osher Research Center. An adjunct therapy is one that’s used together with primary medical treatments, either to address a disease itself or its primary symptoms, or, more generally, to improve a patient’s functioning and quality of life.

Belief systems

You don’t need to subscribe to or learn much about tai chi’s roots in Chinese philosophy to enjoy its health benefits, but these concepts can help make sense of its approach:

  • Qi — an energy force thought to flow through the body; tai chi is said to unblock and encourage the proper flow of qi.

  • Yin and yang — opposing elements thought to make up the universe that need to be kept in harmony. Tai chi is said to promote this balance.

Tai chi in motion

A tai chi class might include these parts:

Warm-up. Easy motions, such as shoulder circles, turning the head from side to side, or rocking back and forth, help you to loosen your muscles and joints and focus on your breath and body.

Instruction and practice of tai chi forms. Short forms — forms are sets of movements — may include a dozen or fewer movements; long forms may include hundreds. Different styles require smaller or larger movements. A short form with smaller, slower movements is usually recommended at the beginning, especially if you’re older or not in good condition.

Qigong (or chi kung). Translated as “breath work” or “energy work,” this consists of a few minutes of gentle breathing sometimes combined with movement. The idea is to help relax the mind and mobilize the body’s energy. Qigong may be practiced standing, sitting, or lying down.

Getting started

The benefits of tai chi are generally greatest if you begin before you develop a chronic illness or functional limitations. Tai chi is very safe, and no fancy equipment is needed, so it’s easy to get started. Here’s some advice for doing so:

Don’t be intimidated by the language. Names like Yang, Wu, and Cheng are given to various branches of tai chi, in honor of people who devised the sets of movements called forms. Certain programs emphasize the martial arts aspect of tai chi rather than its potential for healing and stress reduction. In some forms, you learn long sequences of movements, while others involve shorter series and more focus on breathing and meditation. The name is less important than finding an approach that matches your interests and needs.

Check with your doctor . If you have a limiting musculoskeletal problem or medical condition — or if you take medications that can make you dizzy or lightheaded — check with your doctor before starting tai chi. Given its excellent safety record, chances are that you’ll be encouraged to try it.

Consider observing and taking a class. Taking a class may be the best way to learn tai chi. Seeing a teacher in action, getting feedback, and experiencing the camaraderie of a group are all pluses. Most teachers will let you observe the class first to see if you feel comfortable with the approach and atmosphere. Instruction can be individualized. Ask about classes at your local Y, senior center, or community education center. The Arthritis Foundation (www.arthritis.org; 800-283-7800, toll-free) can tell you whether its tai chi program, a 12-movement, easy-to-learn sequence, is offered in your area.

If you’d rather learn at home, you can buy or rent videos geared to your interests and fitness needs (see “Selected resources”). Although there are some excellent tai chi books, it can be difficult to appreciate the flow of movements from still photos or illustrations.

Talk to the instructor. There’s no standard training or licensing for tai chi instructors, so you’ll need to rely on recommendations from friends or clinicians and, of course, your own judgment. Look for an experienced teacher who will accommodate individual health concerns or levels of coordination and fitness.

Dress comfortably. Choose loose-fitting clothes that don’t restrict your range of motion. You can practice barefoot or in lightweight, comfortable, and flexible shoes. Tai chi shoes are available, but ones you find in your closet will probably work fine. You’ll need shoes that won’t slip and can provide enough support to help you balance, but have soles thin enough to allow you to feel the ground. Running shoes, designed to propel you forward, are usually unsuitable.

Gauge your progress. Most beginning programs and tai chi interventions tested in medical research last at least 12 weeks, with instruction once or twice a week and practice at home. By the end of that time, you should know whether you enjoy tai chi, and you may already notice positive physical and psychological changes.

No pain, big gains

Although tai chi is slow and gentle and doesn’t leave you breathless, it addresses the key components of fitness — muscle strength, flexibility, balance, and, to a lesser degree, aerobic conditioning. Here’s some of the evidence:

Muscle strength. In a 2006 study published in Alternative Therapies in Health and Medicine, Stanford University researchers reported benefits of tai chi in 39 women and men, average age 66, with below-average fitness and at least one cardiovascular risk factor. After taking 36 tai chi classes in 12 weeks, they showed improvement in both lower-body strength (measured by the number of times they could rise from a chair in 30 seconds) and upper-body strength (measured by their ability to do arm curls).

In a Japanese study using the same strength measures, 113 older adults were assigned to different 12-week exercise programs, including tai chi, brisk walking, and resistance training. People who did tai chi improved more than 30% in lower-body strength and 25% in arm strength — almost as much as those who participated in resistance training, and more than those assigned to brisk walking.

“Although you aren’t working with weights or resistance bands, the unsupported arm exercise involved in tai chi strengthens your upper body,” says internist Dr. Gloria Yeh, an assistant professor at Harvard Medical School. “Tai chi strengthens both the lower and upper extremities and also the core muscles of the back and abdomen.”

Flexibility. Women in the 2006 Stanford study significantly boosted upper- and lower-body flexibility as well as strength.

Balance. Tai chi improves balance and, according to some studies, reduces falls. Proprioception — the ability to sense the position of one’s body in space — declines with age. Tai chi helps train this sense, which is a function of sensory neurons in the inner ear and stretch receptors in the muscles and ligaments. Tai chi also improves muscle strength and flexibility, which makes it easier to recover from a stumble. Fear of falling can make you more likely to fall; some studies have found that tai chi training helps reduce that fear.

Aerobic conditioning. Depending on the speed and size of the movements, tai chi can provide some aerobic benefits. But in the Japanese study, only participants assigned to brisk walking gained much aerobic fitness. If your clinician advises a more intense cardio workout with a higher heart rate than tai chi can offer, you may need something more aerobic as well.

Tai chi for medical conditions

When combined with standard treatment, tai chi appears to be helpful for several medical conditions. For example:

Arthritis. In a 40-person study at Tufts University, presented in October 2008 at a meeting of the American College of Rheumatology, an hour of tai chi twice a week for 12 weeks reduced pain and improved mood and physical functioning more than standard stretching exercises in people with severe knee osteoarthritis. According to a Korean study published in December 2008 in Evidence-based Complementary and Alternative Medicine, eight weeks of tai chi classes followed by eight weeks of home practice significantly improved flexibility and slowed the disease process in patients with ankylosing spondylitis, a painful and debilitating inflammatory form of arthritis that affects the spine.

Low bone density. A review of six controlled studies by Dr. Wayne and other Harvard researchers indicates that tai chi may be a safe and effective way to maintain bone density in postmenopausal women. A controlled study of tai chi in women with osteopenia (diminished bone density not as severe as osteoporosis) is under way at the Osher Research Center and Boston’s Beth Israel Deaconess Medical Center.

Breast cancer. Tai chi has shown potential for improving quality of life and functional capacity (the physical ability to carry out normal daily activities, such as work or exercise) in women suffering from breast cancer or the side effects of breast cancer treatment. For example, a 2008 study at the University of Rochester, published in Medicine and Sport Science, found that quality of life and functional capacity (including aerobic capacity, muscular strength, and flexibility) improved in women with breast cancer who did 12 weeks of tai chi, while declining in a control group that received only supportive therapy.

Heart disease. A 53-person study at National Taiwan University found that a year of tai chi significantly boosted exercise capacity, lowered blood pressure, and improved levels of cholesterol, triglycerides, insulin, and C-reactive protein in people at high risk for heart disease. The study, which was published in the September 2008 Journal of Alternative and Complementary Medicine, found no improvement in a control group that did not practice tai chi.

Heart failure. In a 30-person pilot study at Harvard Medical School, 12 weeks of tai chi improved participants’ ability to walk and quality of life. It also reduced blood levels of B-type natriuretic protein, an indicator of heart failure. A 150-patient controlled trial is under way.

Hypertension. In a review of 26 studies in English or Chinese published in Preventive Cardiology (Spring 2008), Dr. Yeh reported that in 85% of trials, tai chi lowered blood pressure — with improvements ranging from 3 to 32 mm Hg in systolic pressure and from 2 to 18 mm Hg in diastolic pressure.

Parkinson’s disease. A 33-person pilot study from Washington University School of Medicine in St. Louis, published in Gait and Posture (October 2008), found that people with mild to moderately severe Parkinson’s disease showed improved balance, walking ability, and overall well-being after 20 tai chi sessions.

Sleep problems. In a University of California, Los Angeles, study of 112 healthy older adults with moderate sleep complaints, 16 weeks of tai chi improved the quality and duration of sleep significantly more than standard sleep education. The study was published in the July 2008 issue of the journal Sleep.

Stroke. In 136 patients who’d had a stroke at least six months earlier, 12 weeks of tai chi improved standing balance more than a general exercise program that entailed breathing, stretching, and mobilizing muscles and joints involved in sitting and walking. Findings were published in the January 2009 issue of Neurorehabilitation and Neural Repair.

Writing makes you happier

It seems much of the literature on the benefits of writing deals with “expressive writing,” or putting what you think and feel to paper (or, let’s be honest, to the keyboard).

For instance, one form of expressive writing might be thinking about and writing out your goals in life—an activity that research [1] has shown is beneficial for motivation.

Even blogging “undoubtedly affords similar benefits” [2] to private expressive writing in terms of the therapeutic value.

Expressive writing has also been linked to improved mood, well-being, and reduced stress levels for those who engage in it regularly.

Research [3] by Laura King shows that writing about achieving future goals and dreams can make people happier and healthier. Similarly, there’s plenty of evidence [4] that keeping a gratitude journal can increase happiness and health by making the good things in life more salient.

And Jane Dutton and I found [5] that when people doing stressful fundraising jobs kept a journal for a few days about how their work made a difference, they increased their hourly effort by 29% over the next two weeks.

Many people shun expressive writing because they don’t fully understand what it means. It doesn’t necessarily mean spilling your guts in essays starting with “Dear Diary.”

Writing leads to better thinking + communicating

Laziness with words creates difficulty in describing feelings, sharing experiences, and communicating with others.

Constantly having that “tip of the tongue” [6] feeling, or being able to flesh out thoughts in your mind only to have them come stumbling out when you speak is very frustrating. It paints an unfair picture of you, and regular writing can keep this from happening.

In both emotional intelligence and in “hard sciences” like mathematics, writing has been shown [7] to help people communicate highly complex ideas more effectively.

Writing helps eliminate “it sounded good in my head” syndrome. It forces ideas to be laid out bare for the thinker to see, where it is much less likely that they will be jumbled up like they are in your head (hey, it’s crowded up there).

Is writing an outlet for handling hard times?

The connection with expressive writing and traumatic events is quite complex.

On one hand, I’ve seen a study or two that shows especially stoic people tend not to receive many benefits when they write about their troubling times.

On the other hand, there are some pretty amazing studies that conclusively show writing about trauma is a powerful way to come to terms with what happened, and to accept the outcome.

In one interesting study [8] that followed recently fired engineers, the researchers found that those engineers who consistently engaged with expressive writing were able to find another job faster.

The engineers who wrote down their thoughts and feelings about losing their jobs reported feeling less anger and hostility toward their former employer. They also reported drinking less. Eight months later, less than 19% of the engineers in the control groups were reemployed full-time, compared with more than 52% of the engineers in the expressive writing group.

In an older study [9], writing about traumatic events actually made the participants more depressed… until about ~6 months later, when the emotional benefits started to stick.

One participant noted: “Although I have not talked with anyone about what I wrote, I was finally able to deal with it, work through the pain instead of trying to block it out. Now it doesn’t hurt to think about it.”

It seems that timing is critical for expressive writing to have an impact. “Forcing” the process to happen may only worsen things, but if it is an activity that is engaged in naturally, the benefits seem to be clear for many traumas [10].

Writing keeps you sharp with age

Writing is a thinking exercise, and like physical exercise, it can help keep you “in shape” as you age.

While the only research that I’ve seen discussed [11] mentions hand written ideas as a good cognitive exercise, I don’t think the leap to typing is all that far.

Just like how friendships help keep you happy and healthy through their ties to social interaction and dialogue, writing seems like the private equivalent — it keeps you thinking regularly and helps keeps the mental rust from forming.

Writing leads to increased gratitude

Counting your blessings is an activity that is proven to enhance one’s outlook on life.

As the authors noted one study [12], subjects who reflected on the good things in their life once a week (by writing them down) were more positive and motivated about their current situation and their future.

The thing was, when they wrote about them every day, the benefits were minimal.

This makes sense. Too much of any activity, especially something like reflecting on one’s blessings, can feel disingenuous and just plain boring if it is done too often.

In spite of this, it is interesting to me that writing about the good things in your life has such an impact. Perhaps because it forces you to really look at why those things make you happy.

Writing closes out your “mental tabs”

Have you ever had too many Internet tabs open at once? It is a madhouse of distraction.

Sometimes I feel like my brain has too many tabs open at once. This is often the result of trying to mentally juggle too many thoughts at the same time.

Writing allows abstract information to cross over into the tangible world. It frees up mental bandwidth, and will stop your Google Chrome brain from crashing due to tab overload.

Although I’ve heard it argued [13] that the information age might be making memories worse, I’m inclined to cite the quote about Hemingway from that very same article:

Hemingway’s words came from experience. When his wife lost a suitcase that contained all existing copies of his short stories, the work was, to his mind, gone for good. He had written himself out the first time around. He couldn’t recapture it–whatever it was–again.

Getting important ideas down alleviates the stress caused by anticipating this dreadful outcome. I’ve personally never felt inclined to not work on something just because I “archived” the idea with some notes or an outline—in fact, I’m more likely to work on it since it has already been started!

Remember these wise words from Mitch Hedberg:

I sit at my hotel at night, I think of something that’s funny, then I go get a pen and I write it down. Or if the pen’s too far away, I have to convince myself that what I thought of ain’t funny.

Don’t let that happen to you!

Writing leads to better learning

Information often better stays with us when learn as though we need to teach.

This concept of having a “writer’s ear” never fully clicked with me until I started writing regularly.

There’s a certain discipline required to create interesting written work that demands the individual be receptive and focused on finding new sources of information, inspiration, and insight. I’ve read books, listened to podcasts/radio, and watched videos I may have normally put off in order to learn something interesting that I might write about later.

Simply being a curator of good ideas encourages deeper thinking, research, and “heading down the rabbit hole” in order to find unique takes on topics that matter to you.

Committing to creating a volume of work also allows you to tackle big ideas more effectively.

From humble beginnings, writing around a certain topic for some time will allow you to build off of older thoughts, utilizing what you’ve already written down to develop ideas on a grander scale (I’m sure many writers have had a paragraph lead to an essay, which lead to a series of articles, which lead to a book).

In this way, writing encourages a specific style of personal development. You’ll begin to want to build on ideas, which will lead to a further exploration of your interests and a better understanding of your subject matter as you push onward into new topics and angles.

Writing is leadership at scale

Despite the fact that the world is now being suffocated by ‘new media,’ there are obviously a lot of interesting opportunities that an “anyone can publish” world brings about.

The ability to leave an impact at scale through your words alone is a pretty amazing concept.

The emails I’ve personally received, both for my personal work and my writing at Help Scout have been truly humbling. There’s a bit of a “creative shock” the first time someone emails you thanking you for the work you’ve put how, and how it has helped them.

Without a doubt, the positive feedback for this “leadership at scale” leads to a feeling of gratitude and happiness for the writer.

Even in the face of criticism, writers learn to build thick skin like few others. Criticism, even unwarranted criticism, is the breakfast of champions.

4 Simple Steps To Get Great Posture (Video)

Our posture both reflects and creates how we feel and how we live, so obviously good posture is so important! When it's not so good, we often feel more sluggish and weak, but when it's good, we feel great! We have lots of energy, and we're strong enough to do anything we want.

Since our posture is created by what we do all day, it might take more than a few shoulder-rolls to get everything perfect. But there are some things you can actually do for just a few minutes each day that will help your body learn (and remember!) the optimal ways of moving and holding still. From here, great posture becomes an all-day, every-day good habit!

It's helpful to remember that posture isn't just about your shoulders and back. How you hold yourself builds on a chain of interconnected parts —  beginning at your ankles and then knees, up through your hips, belly, and lower back. From there it runs up the full length of your spine, into your neck and shoulders.

You want this chain to be not too taut, not too loose, but just right in the middle. Think of your body like water in a glass —  easily and fluidly movable, encompassed by a nice big container that keeps us from spilling all over the place!

Here are four key areas of movement that I cover in-depth for you in the video below. Try getting into each of these areas every single day, and your body will start to align perfectly and your back will thank you!

1. Get on your hands and knees (or feet!) and move everything you've got, in every direction you can move it.

This gives you a great way to move and explore the full length of your spine easily, in every possible direction. This kind of movement is critical for development of all the small supporting muscles along your spine, which in turn helps your ligaments restore and maintain proper position for healthy alignment.

2. Get up on your feet and challenge your balance.

By playing with balance, you further develop and fine-tune all the small supporting muscles in your body. These muscles are the key to how you hold yourself. When they're engaged and evenly-developed, you will naturally hold yourself up just right (without even tiring!) and be ready for anything.

3. Get all-around STRONG in your core!

We all know a strong core is necessary for a healthy back and good posture. Here, we'll get into your core as we did before, by moving evenly in every possible direction. By starting this multi-directional movement right from your center, we'll check off a key element in healing and strengthening your body's natural alignment systems.

4. Release and relax the hips and hamstrings.

Finally, we wind it down with some easygoing releases for your hips and thighs, by exploring all around these areas again, in every possible direction. Your legs and hips are a key part of the chain that sets up how you stand, sit, and move, so keeping them stress-free and easily movable is important.

When you awaken every inch of your body and move happily, your body becomes a wonderful orchestra —  all the pieces in tune, playing the best music there is.

Want perfect posture? Tune your orchestra! Move happily, everything you've got, in every direction you can. Do it every day, and you're going to like what happens to your body, I assure you.

Here's the video to get you started. Enjoy!

Why Do We Sneeze?

Whether you sneeze because of a cold, or after sex or a good meal or in sunlight, the good old Achoo is the body's way of ridding itself of irritants.

A sneeze seems like a simple thing—especially since it’s so common—but it’s a complex neurological phenomenon that occurs for a multitude of different reasons.

Sneezing, technically known as sternutation, is triggered by anything that irritates the nerve endings in the mucous membranes of the sinuses. The irritation sets off a reaction that sends signals to the brain stem, which controls most of the body’s essential functions, like breathing. The brain then tells the body to leap into action. The eyes close, the whole body contracts, and the glottis—a slit-like opening between the vocal cords—snaps shut as the body forcefully inhales. That’s followed by a powerful exhalation that, because the glottis is closed, has to go up through the nasal passage—the “achoo.” The exhalation expels the irritants.

A sneeze can contain 40,000 droplets (often packed with bacterial and viral particles), rushing out at an average speed of 100 miles per hour, but can range up to 600 mph. That’s a fast and furious way to spread disease, which is why doctors urge people to sneeze into their elbow.

But there’s still much that’s not known about what happens in the brain and why the sneeze mechanism developed.

Sneezing is most commonly associated with allergies, and colds, but can also be a non-allergic reaction to dust, perfume, mold, smoke, or even a change in temperature or the moisture content of the air. And, sneezing “may be seen with exercise, with a full stomach, and even after sex,” says Andy Nish, chief of allergy and asthma for the Northeast Georgia Physicians Group in Gainesville, Georgia.

Why after sex? Interestingly, erectile tissue is found not only in the genital area, but also in the mucous membranes of the nose, says Nish. The association between sneezing and sex was first written about in the 1880s, but was not more fully described until the 1970s. Although there seems to be a physiological cause for sneezing after orgasm, it’s still considered to be relatively rare.

Sneezing after a good meal has been reported even less often, but it still managed to get its own medical term—“snatiation”—for sneezing combined with satiation.

Some people sneeze in reaction to sunlight or bright light. Nish says the photic sneeze reflex is a genetic trait that affects about a quarter of humans. The reflex is also known as the ACHOO (autosomal dominant compelling helio-ophthalmic outburst) syndrome.

Almost everyone sneezes at some point—and often in clusters, which is likely a way for the body to fully clear the irritant, says Nish. “But an inability to sneeze over a prolonged period of time might raise concern for problems with the nervous system, since intact nerve pathways to and from the brain are necessary,” he says.

Sneezing is only rarely associated with serious disease. There have been reports of sneezing accompanying seizures, and preceding a stroke. So-called intractable—or incessant—sneezing has been identified as a potential psychiatric disorder in adolescent girls. Contrary to popular myth, sneezing does not cause the heart to stop.

It’s okay to try to prevent a sneeze, but it might lead to an unpleasant feeling, says Nish. If you feel a sneeze coming on and try to suppress or contain it, that may temporarily increase the pressure in your ears and upper airway, causing a popping sensation.

Humans are not the only creatures to sneeze. Nish says that cats, dogs, chickens and iguanas all sneeze. “Most of these sneezes are probably for the same reason that we sneeze, but in iguanas, the sneeze is actually an important means of getting rid of excess salt that its body no longer needs,” he says.

Throughout human history, sneezing has been interpreted as both good and bad. “The Greeks and the Romans took sneezing as a sign of wellness and expressed their good wishes to the person who sneezed using the phrase ‘Live long’ or ‘May Jupiter bless you,’” wrote Turkish researchers Murat Songu and Cemal Cingi in an overview article about the sneeze.

In the Talmud, it is considered to be a favorable omen if someone sneezes while praying, and it is common in China and Japan to believe that if a person sneezes without a reason, this means that somebody else is talking about him, according to Songu and Cingi.

Pagans thought that sneezing got rid of the devil, but that it also created an opening for “invasion by Satan and evil spirits, or even caused part of one’s soul being ‘thrown out of the body,’” say Songu and Cingi, who trace the phrase “God bless you,” to this Pagan belief.

While you might bless someone for sneezing, “the sneeze is actually a protective mechanism for them, but maybe not for you,” says Nish.
