Regular exercise can keep lifestyle diseases away

April 5, 2015

Apr 5: Cardiovascular disease, diabetes, and osteoporosis - Indians are facing an unhealthy future burdened with a slew of lifestyle diseases. But instead of expensive medication and therapy, the cure lies in making exercise a compulsory part of everyday life, health experts say.

"Indians are increasingly leading a sedentary and machine-dependent life, which may seem comfortable but has extremely adverse effects on health," T.S. Kler, Head of the Department Cardiology, Fortis Escorts Heart Institute and Research Centre said.

Regular exerciseKler said with increasingly hectic lifestyles, most Indians in urban areas nowadays do not walk to the neighbourhood store but rather order groceries on phone for home delivery or drive down.

"We do not climb stairs any more, with lifts being omnipresent. Riding bicycles to work or to school is not cool in urban areas any more. Forget adults, this conditioning begins with children who prefer to stay indoors watching television or playing video games rather than spending time in the playground," he added.

"We all know that cardiovascular diseases are today a major health concern in India. They are the single largest leading cause of deaths in the country, and relatively younger people are today afflicted by coronary artery disease," the noted cardiologist said.

Various surveys done in India have shown that the incidence of coronary heart disease is 8-10 percent in urban areas and 5-6 percent in rural areas.

Kler said regular exercise can help prevent risk factors for cardiovascular diseases such as hypertension and type II diabetes. It also keeps the weight in check.

"Incidences of coronary artery disease can be reduced substantially if the entire Indian population religiously takes to physical exercise. Even 30 minutes of moderate exercise daily can be immensely beneficial. We need a national focus on this less-talked about subject," Kler said.

According to Rajeev K. Sharma, senior consultant orthopedics and joint replacement surgery, Indraprastha Apollo Hospital: "Adequate levels of physical activity decreases the risk of a hip or vertebral fracture and helps control weight. In fact, exercise is very crucial for maintaining good bone health, besides adequate intake of calcium."

"WHO estimates that globally, one in four adults is not active enough while more than 80 percent of the world's adolescent population is insufficiently physically active. This is a dreadful scenario as all these inactive people are making themselves vulnerable to several health issues," he said.

Osteoporosis-related injuries such as vertebrae fractures not only cause pain but also degrade the quality of life, curtail movement and increase dependence. Since the bone is a living tissue, it becomes stronger when subjected to exercise, Sharma said, adding that loss of bone mineral density that begins during the 30s can be curtailed by exercising regularly.

"People who exercise are found to have greater peak bone mass as compared to people who do not exercise."

According to the International Osteoporosis Foundation, the malaise annually causes more than 8.9 million fractures around the globe.

"Though exercising can, to a large extent, help in building strong bones, there is a general lack of an exercise culture in India. This needs to change. Schools, colleges and other institutions should take the lead in nurturing an exercising culture."

Harvinder Singh Chhabra, medical director and chief of spine services at Indian Spinal Injuries Centre, Vasant Kunj, said Indians generally do not realize the importance of exercising unless hit by an ailment.

"Many patients start walking regularly after back pain or osteoarthritis has already set in their bodies. We tell them they could have delayed it by being active all their lives," he added.

According to Chhabra, in the West, there is a lot of focus on physical activity and people are moving away from sedentary ways of life. "They are junking television and going for cycling, running, or adventure sports such as rock climbing. This shift is yet to take place in India."

To make exercise a national culture, apart from awareness, many enabling policy measures are also needed.

"In urban areas, several environmental factors discourage people from leading more active lives even if they want to. Lack of public spaces such as parks and grounds, safety issues on the roads, pollution and irksome traffic do not allow many people to step out of homes to run or walk. This needs to change," he said.

The latter half of the 20th century has brought substantial progress in disease control due to expansion of health infrastructure. With food and nutritional consumption also improving for a vast majority of population, life expectancy in India has gone up over the years. Experts say that deaths due to communicable diseases have decreased while those from non-communicable diseases (NCDs) have risen.

NCDs at present account for 53 percent of all deaths and 44 percent of disability adjusted life-years lost. Projections indicate a further increase to 67 percent of all deaths by 2030. Cardiovascular disease is the major contributor to this burden, attributable to 52 percent of NCD-associated deaths and 29 percent of total deaths.

The World Health Organisation (WHO) Director-General Tedros Adhanom Ghebreyesus said that more research needs to be done to better understand the extent to which COVID-19 is being spread by people who don't show symptoms.

"Since early February, we have said that asymptomatic people can transmit COVID-19, but that we need more research to establish the extent of asymptomatic transmission," the WHO chief said at a virtual press conference from Geneva on Wednesday, Xinhua news agency reported.

"That research is ongoing, and we're seeing more and more research being done," he added.

Saying that the world has been achieving a lot in knowing the new virus, the WHO chief told reporters that "there's still a lot we don't

"WHO's advice will continue to evolve as new information becomes available," he said.

Tedros stressed that the most critical way to stop transmission is to find, isolate and test people with symptoms, and trace and quarantine their contacts.

"Many countries have succeeded in suppressing transmission and controlling the virus doing exactly this," Tedros said.

Meanwhile, Michael Ryan, executive director of WHO Health Emergencies Program, said Wednesday that the COVID-19 pandemic is still evolving.

"If we look at the numbers... this pandemic is still evolving. It is growing in many parts of the world," he said. "We have deep concerns that health systems of some countries are struggling, under a huge strain and require our support, our help and our solidarity."

He said "each and every country has a different combination of risks and opportunities, and it's really down to national authorities to carefully consider where they are in the pandemic."

In Europe, the risk issue now are about travels and the opening of the schools, around risk management, mass gathering, surveillance and contact tracing, said the WHO official.

In Southeast Asian countries, where to a great extent transmissions have been under control, governments are more concerned about the re-emergence of clusters, while in South America, the issue of PPE for health workers has not gone away, said Ryan.

As regards Africa, Ryan said the death rates have been very low in the past week, but the health system can be overwhelmed, as it would have to cope with other diseases such as malaria.

Feb 22: The subjective feeling of well-being experienced by many people with the practice of meditation is associated with specific changes in the brain, according to a study which may lead to better clinical recommendations of the practice.

The study, published in the journal Brain and Cognition, examined the effects of the technique known as Transcendental Meditation (TM), which consists of the silent repetition of a meaningless sound.

In the study, the researchers from the IMT School for Advanced Studies Lucca in Italy, enrolled 34 healthy young volunteers and divided them in two groups.

They said the first group practised TM 40 minutes per day in two sessions of 20 minutes each, one in the morning and the other in the evening.

The second group, the scientists said, did not change its daily routine.

Using questionnaires, they also measured the anxiety and stress levels of all the participants at the beginning of the study, as well as the subjects' ability to manage stressful situations.

According to the researchers, the participants were also subjected to a functional magnetic resonance imaging (fMRI) brain scan, in order to measure the organ's activity at rest, and changes in the excitation among different cerebral areas.

They repeated the tests after three months, at the end of the study.

According to the study, the levels of anxiety and stress perceived by the subjects who followed the meditation program were significantly reduced in comparison with those of the volunteers who did not practice TM.

"Magnetic resonance imaging also shows that the reduction of anxiety levels is associated with specific changes in the connectivity between different cerebral areas, such as precuneus, left parietal lobe and insula, which all have an important role in the modulation of emotions and inner states," said study co-author Giulia Avvenuti from the IMT School for Advanced Studies Lucca.

"In the control group, instead, none of these changes was observed. The fact that Transcendental Meditation has measurable effects on the 'dialogue' between brain structures involved in the modulation of affective states opens new perspectives for the understanding of brain-mind relationships," said Pietro Pietrini, IMT School's Director, and co-author of the study.

"It also extends the results of recent research suggesting that drugs therapies and psychotherapy leverage on the same biological mechanism," Pietrini said.

According to the researchers, even a few months of practice of TM can have positive effects which can be correlated with measurable changes in the brain.

Singapore, May 25: COVID-19 patients are no longer infectious after 11 days of getting sick even though some may still test positive, according to a new study by infectious disease experts in Singapore.

A positive test "does not equate to infectiousness or viable virus," a joint research paper by Singapore's National Centre for Infectious Diseases and the Academy of Medicine, Singapore said. The virus "could not be isolated or cultured after day 11 of illness."

The paper was based on a study of 73 patents in the city-state.

The latest findings may have implications on the country's patient discharge policy. The discharge criteria is currently based on negative test results rather than infectiousness.

Singapore's strategy on managing COVID-19 patients is guided by the latest local and international clinical scientific evidence, and the Ministry of Health will evaluate if the latest evidence can be incorporated into its patient clinical management plan, according to a report by the Straits Times.

So far, 13,882, or about 45% of the total 31,068 Covid-19 patients in Singapore have been discharged from hospitals and community facilities. Singapore reported 642 new Covid-19 cases as of noon on Saturday.

The government has been actively screening pre-school staff as it prepares to reopen pre-schools from June 2. On Friday, two pre-school employees tested positive for the novel coronavirus, bringing the total number of confirmed cases among pre-school staff to seven, according to the Ministry of Health.
