Yoga may boost aging brains

According to a small study, older women who practice yoga may have greater "thickness" in areas of the brain involved in memory and attention. Researchers found that even compared with other healthy, active women their age, yoga practitioners typically had greater cortical thickness in the brain's left prefrontal cortex. That could be good news because, as the researchers pointed out, cognitive impairment from aging is usually associated with less volume in cortical areas of the brain associated with attention tasks, and decreases in memory.

Yoga, meditation improve brain function and energy levels, study shows

Practicing brief sessions of Hatha yoga and mindfulness meditation can significantly improve brain function and energy levels, according to a new study from the University of Waterloo. The study found that practicing just 25 minutes of Hatha yoga or mindfulness meditation per day can boost the brain's executive functions, cognitive abilities linked to goal-directed behavior and the ability to control knee-jerk emotional responses, habitual thinking patterns and actions.

Health Tip: boosting your memory

The American Psychological Association suggests following steps you can take to help boost your memory: Take mental snapshots: For example, visualize your car keys in a wooden bowl near your front door. This will help you remember where you left them; Train your brain: if you meet someone named Mr. Brown, for example, picture him covered in that color; Vanishing cues: if you can't remember a name, write down all the letters that you can remember. Eventually, you may be able to fill in the blanks; Use technology. Your smart phone probably has a note-taking app that can send you an alert at a certain important time.

Meditation and yoga can 'reverse' DNA reactions which cause stress

According to a new study, mind-body interventions (MBIs) such as meditation, yoga and Tai Chi don't simply relax us; they can 'reverse' the molecular reactions in our DNA which cause ill-health and depression. The researchers focus on how gene expression is affected; in other words the way that genes activate to produce proteins which influence the biological make-up of the body, the brain and the immune system. When a person is exposed to a stressful event, their sympathetic nervous system (SNS) -- the system responsible for the 'fight-or-flight' response - is triggered, in turn increasing production of a molecule called nuclear factor kappa B (NF-kB) which regulates how our genes are expressed. However, people who practise MBIs exhibit the opposite effect - namely a decrease in production of NF-kB and cytokines, leading to a reversal of the pro-inflammatory gene expression pattern and a reduction in the risk of inflammation-related diseases and conditions.

Why Yoga, Tai Chi and Meditation are good for you

Relax your mind and then consider this: The physical and mental health benefits of pursuits like yoga and meditation begin in your genes, a new review suggests. The researchers reviewed 18 studies, involving a total of 846 people, to examine how the behavior of genes is affected by yoga, tai chi, meditation and other mind-body interventions and conclude that such activities reverse molecular reactions in DNA that cause poor health and depression. Millions of people around the world already enjoy the health benefits of mind-body interventions like yoga or meditation, but what they perhaps don't realize is that these benefits begin at a molecular level and can change the way our genetic code goes about its business.

The Science behind Acupuncture—and why it really works

The concept of turning a human into a pincushion makes some people squeamish, but the practice clearly appeals to many - after all, acupuncture has been around for more than 3,000 years and is currently practiced almost everywhere in the world. Rooted in key principles of traditional Chinese medicine, acupuncture is based on the idea of creating and sustaining balance within the body. While the points touched by an acupuncturist might seem random to most of us, researchers have found acupoints are packed full of neurovascular structures, which means that inserting a small sterile needle into a specific point in your leg actually can trigger a reaction in your eye.

Health Tip: diet and activity may help prevent cancer

Multiple studies have shown a correlation between diet and physical activity on your risk of developing cancer. Here are suggestions from the American Cancer Society - (1) maintain a healthy body weight: being obese causes the body to produce more estrogen and insulin. These hormones may promote cancer growth; (2) Get regular exercise: daily exercise helps you maintain a healthy weight, improve hormone levels and strengthen your immune system. The American Cancer Society recommends at least 150 minutes of moderate-intensity activity or 75 minutes of vigorous-intensity exercise each week; (3) eat lots of plant-based foods; (4) Limit daily alcohol; (5) Quit smoking.

Diabetes Diet: 7 foods that can help control your blood sugar levels naturally

Your diet plays an important role in managing diabetes. In fact, your diet and lifestyle are important aspects of diabetes management and treatment.  One reason is that the food you eat on a day to day basis has a direct impact on your blood sugar levels. For instance, high carb foods raise your blood sugar levels. The digestive system breaks down the digestible ones into sugar, which enters the blood. But then again, not all carbohydrates are bad. Complex carbohydrates like whole grains take longer to digest while simple carbs like white flour and refined sugar may cause sudden spikes in your blood sugar levels. Here are seven foods barley, bananas, nuts, bitter gourd (karela), fenugreek seeds, protein rich foods and amla etc that can help in controlling your blood sugar levels naturally.

Could big lifestyle changes be key to managing type 2 diabetes?

A new study showed that adding intensive lifestyle management to standard diabetes care (diabetes medication and usual lifestyle change advice) brought blood sugar into a non-diabetic range. The intensive intervention worked so well that "half of the intervention group did not need glucose-lowering medications to maintain or even improve [blood sugar] control.

Sugars in human mother's milk are new class of antibacterial agents

A new study has found that sugars in mother's' milk do not just provide nutrition for babies but also help protect them from bacterial infections, making them a new class of antimicrobial agent. Mother's milk, which consists of a complex and continually changing blend of proteins, fats and sugars, helps protect babies against bacterial infections. In the past, scientists have concentrated their search for the source of its antibacterial properties on the proteins it contains. However, an interdisciplinary team of chemists and doctors at Vanderbilt University have discovered that some of the carbohydrates in human milk not only possess antibacterial properties of their own but also enhance the effectiveness of the antibacterial proteins also present.
