Will Yoga Help People Live Healthier Lifestyles?

            Stress is an unfortunate part of our everyday lives and its effects are felt by everyone.  Stress affects everyone in different degrees but its presence is undoubtedly felt throughout the nation.  77 percent of people in the United States regularly experience physical symptoms caused by stress and 73 percent of people regularly experience psychological symptoms due to stress (“Stress Statistics”).  When left untreated, stress can lead to a series of declining health conditions, which is why it is important to keep it in check.  Yoga is one way that many Americans are turning toward to help effectively manage the stress in their lives.  Yoga not only improves stress but various other health ailments affecting many in the United States including arthritis, high blood pressure, and back pain.  People should do yoga because it reduces stress and tension and creates a sense of wellbeing both physically and mentally.

            Yoga is a valuable exercise tool that helps most people live healthier lifestyles.  In my experience, people of all shapes, sizes, and ages can do yoga and it is widely available for little cost.  Since yoga is easily accessible to most people, it has increasingly become a health tool for many.  My own experience with yoga has been positive and I have definitely noticed results that have helped me with the stress in my life.  Yoga has not only increased my flexibility and helped my body feel stronger, but above all else it has reduced my stress levels.  After doing yoga many people, myself included, have felt refreshed and ready to tackle the next task of the day. 

            Various studies have shown that yoga is an effective and beneficial means of not only reducing stress and tension but also improving health.  Research shows that yoga helps manage or control anxiety, arthritis, asthma, back pain, blood pressure, carpal tunnel syndrome, chronic fatigue, depression, diabetes, epilepsy, headaches, heart disease, multiple sclerosis, stress and other conditions and diseases (Tunney).  Over 75 scientific trials have been published on yoga in major medical journals (“Yoga for Arthritis”).  These studies have shown that yoga is a safe and effective way to increase physical activity that also has important psychological benefits due to its meditative nature.  As with other forms of exercise, yoga can increase muscle strength, improve flexibility, enhance respiratory endurance, and promote balance (“Yoga for Arthritis).  Yoga is also associated with increased energy and fewer bodily aches and pains (“Yoga for Arthritis”).  Furthermore, yoga is associated with increased mental energy as well as positive feelings (such as alertness and enthusiasm) and fewer negative feelings (such as reduced anxiety and aggressiveness) (“Yoga for Arthritis”). 

            Regular physical activity, particularly yoga, is especially important for people with arthritis, who often have decreased muscle strength, physical energy, and endurance, due to their arthritis and the tendency to be inactive (“Yoga for Arthritis”).  Being inactive can begin a downward spiral where pain increases, leading to more inactivity which leads to greater pain and disability (“Yoga for Arthritis”). The psychological benefits of exercise (in this case yoga), such as stress reduction, fewer depressive symptoms, improved coping and well-being, and enhanced immune functioning also contribute to greater overall health (“Yoga for Arthritis”).  

            In another recent study, researchers focused on 16 studies that recorded the effects of practicing yoga on mental-health issues ranging from depression, schizophrenia, ADHD, sleep complaints, and eating disorders to cognitive problems. They found positive effects of the mind-and-body practice for all conditions with the exception of eating disorders and cognition (Sifferlin).  (These two studies involved too few participants or produced conflicting results to draw any meaningful conclusions) (Sifferlin).  Some of the studies included in the analysis suggested that yoga might affect the body in ways similar to antidepressants and psychotherapy (Sifferlin).  For instance, yoga may influence brain chemicals, known as neurotransmitters, by boosting levels of feel-good agents like serotonin, lowering inflammation, reducing oxidative stress, and producing a healthier balance of lipids and growth factors, just as other forms of exercise do (Sifferlin).  In terms of stress reduction the studies showed that yoga appears to control stress response systems by reducing perceived stress and anxiety (Sifferlin).  This, in turn, decreases physiological stimulation, for example, reducing heart rate, lowering blood pressure, and easing respiration (Sifferlin).  There is also evidence that practicing yoga helps increase heart rate variability, an indicator of the body's ability to respond to stress more flexibly (“Yoga for anxiety and depression”).  Researchers say there is enough evidence to warrant an even larger study on the effects of yoga on mental health, and it should be considered as part of the treatment for more disorders (Sifferlin).

            Other studies showed the benefits of practicing yoga on improving low-back pain.  One NCCAM-funded study of 90 people with chronic low-back pain found that participants who practiced yoga had significantly less disability, pain, and depression after 6 months (“Yoga for Health”).  In a 2011 study, also funded by NCCAM, researchers compared yoga with conventional stretching exercises or a self-care book in 228 adults with chronic low-back pain (“Yoga for Health”).  The results showed that both yoga and stretching were more effective than a self-care book for improving function and reducing symptoms due to chronic low-back pain (“Yoga for Health”).  In a similar 2011 study, patients who took regular yoga classes experienced a greater improvement in back function than those given conventional treatment alone.  The study involved 313 patients with chronic or recurrent back pain undergoing various forms of treatment including painkillers and physiotherapy (“Yoga for Health”).  In addition to their normal treatment, half were assigned to the specially designed three-month yoga program (“Yoga for Health”).  At the end of the program, they were able to take on 30% more activities than the group confined to traditional care (“Yoga for Health”).  The group that practiced yoga also experienced greater pain reduction (“Yoga for Health”).     

            Several trials have also found that yoga can lower blood pressure, cholesterol, resting heart rates, and help slow the progression of atherosclerosis, which are all risk factors for heart disease (“Yoga for Health”).  While almost any exercise is good for the heart, experts speculate yoga's meditative component may give it an extra boost by helping to stabilize the endothelium, the lining of the blood vessels that, when irritated, contributes to cardiovascular disease (“Yoga for Health”).  Since the lining is reactive to stress, and meditation can lower stress hormones, it is believed yoga causes a flow of events that reduces an individual’s risk of a heart attack or stroke (“Yoga for Health”).

            Another recent study suggests that regular yoga classes could help people with a common heart rhythm problem manage their symptoms while also improving their state of mind.  According to the American Heart Association, about 2.7 million people in the United States have atrial fibrillation (AF), in which the heart's upper chambers quiver chaotically instead of contracting normally (Pittman).  People with AF are often prescribed drugs such as beta blockers to help control their heart rate and rhythm (Pittman). However, researchers noted that the medicines do not alleviate symptoms for all patients, which is where additional treatment like yoga could come in (Pittman).  The new study included 49 people who have had AF for an average of five years (Pittman).  For three months, researchers led by Dr. Dhanunjaya Lakkireddy from the University of Kansas Medical Center in Kansas City tracked study volunteers' heart symptoms, blood pressure, and heart rate, as well as their anxiety, depression, and general quality of life (Pittman).  For the second phase of the study, the same participants went to group yoga classes at least twice a week for an additional three months, again reporting on their symptoms and quality of life (Pittman).  All of the patients were on stable medications throughout the study period (Pittman).  Nonetheless, the number of times they reported heart quivering, which was confirmed by a heart monitor, dropped from almost four times during the first three months to twice during the yoga intervention phase (Pittman).  Their average heart rate also fell from 67 beats per minute at the start of the study to between 61 and 62 beats per minute after yoga (Pittman).  Participants' anxiety scores declined from an average of 34, on a scale of 20 to 80, to 25 after three months of yoga (Pittman).  Depression and general mental health improved as well (Pittman).

            However, some people claim that they cannot do yoga because they are not flexible enough to do all of the positions correctly.  A popular misconception is that yoga focuses merely on increasing flexibility.  Yoga may bring to mind pretzel-like poses requiring considerable strength and balance, but in reality, beginner yoga classes provide simple, gentle movements that gradually build strength, balance, and flexibility (“Yoga for Arthritis”).  Most of the basic poses and positions are easy to do and do not require high amounts of flexibility to get results (“Yoga for Arthritis”).  The positions can also be modified to the individual.  It is suggested that people with high blood pressure, glaucoma, and women who are pregnant should modify or avoid some yoga poses (“Yoga for Health”).  In most cases yoga classes have helped most people improve their health (“Stress Management”). A number of studies have shown that yoga can help reduce stress and anxiety (“Stress Management”).  It can also enhance participants’ moods and overall sense of well-being. (“Stress Management”).  Practicing yoga can lead to improved balance, flexibility, range of motion, and strength, which means that an individual is less likely to injure themselves in other physical endeavors or in their daily activities (“Stress Management”). 

            Yoga not only helps us manage the stress we all feel as a result of our daily lives, but also various other health ailments as well.  Yoga helps control arthritis, high blood pressure, and back pain, among numerous other conditions that many Americans deal with on an everyday basis.  People should ultimately practice yoga because it reduces stress and tension and creates a sense of strength as well as serenity.  Yoga is a valuable exercise tool that helps alleviate the stress that we encounter in our hectic lifestyles as well as improve our physical and mental wellbeing.
