DDT: Pesticide linked to Alzheimer’s

Exposure to a once widely used pesticide, DDT, may increase the chances of developing Alzheimer’s disease, suggest US researchers.

A study, published in JAMA Neurology, showed patients with Alzheimer’s had four times the levels of DDT lingering in the body than healthy people.

Some countries still use the pesticide to control malaria.

Alzheimer’s Research UK said more evidence was needed to prove DDT had a role in dementia.

DDT was a massively successful pesticide, initially used to control malaria at the end of World War Two and then to protect crops in commercial agriculture.

However, there were questions about its impact on human health and wider environmental concerns, particularly for predators.

It was banned in the US in 1972 and in many other countries. But the World Health Organization still recommends using DDT to keep malaria in check.

Not clear
DDT also lingers in the human body where it is broken down into DDE.

The team at Rutgers University and Emory University tested levels of DDE in the blood of 86 people with Alzheimer’s disease and compared the results with 79 healthy people of a similar age and background.

The results showed those with Alzheimer’s had 3.8 times the level of DDE.

However, the picture is not clear-cut. Some healthy people had high levels of DDE while some with Alzheimer’s had low levels. Alzheimer’s also predates the use of DDT.

The researchers believe the chemical is increasing the chance of Alzheimer’s and may be involved in the development of amyloid plaques in the brain, a hallmark of the disease, which contribute to the death of brain cells.

Prof Allan Levey, the director of the Alzheimer’s Disease Research Centre at Emory, said: “This is one of the first studies identifying a strong environmental risk factor for Alzheimer’s disease.

“The magnitude of the effect is strikingly large, it is comparable in size to the most common genetic risk factor for late-onset Alzheimer’s.”

Fellow researcher Dr Jason Richardson added: “We are still being exposed to these chemicals in the United States, both because we get food products from other countries and because DDE persists in the environment for a long time,” .

Dr Simon Ridley, the head of research at the charity Alzheimer’s Research UK, said: “It’s important to note that this research relates to DDT, a pesticide that has not been used in the UK since the 1980s.

“While this small study suggests a possible connection between DDT exposure and Alzheimer’s, we don’t know whether other factors may account for these results.

“Much more research would be needed to confirm whether this particular pesticide may contribute to the disease.”

The Older Mind May Just Be a Fuller Mind

People of a certain age (and we know who we are) don’t spend much leisure time reviewing the research into cognitive performance and aging. The story is grim, for one thing: Memory’s speed and accuracy begin to slip around age 25 and keep on slipping.

The story is familiar, too, for anyone who is over 50 and, having finally learned to live fully in the moment, discovers it’s a senior moment. The finding that the brain slows with age is one of the strongest in all of psychology.

Over the years, some scientists have questioned this dotage curve. But these challenges have had an ornery-old-person slant: that the tests were biased toward the young, for example. Or that older people have learned not to care about clearly trivial things, like memory tests. Or that an older mind must organize information differently from one attached to some 22-year-old who records his every Ultimate Frisbee move on Instagram.

Now comes a new kind of challenge to the evidence of a cognitive decline, from a decidedly digital quarter: data mining, based on theories of information processing. In a paper published in Topics in Cognitive Science, a team of linguistic researchers from the University of Tübingen in Germany used advanced learning models to search enormous databases of words and phrases.

Since educated older people generally know more words than younger people, simply by virtue of having been around longer, the experiment simulates what an older brain has to do to retrieve a word. And when the researchers incorporated that difference into the models, the aging “deficits” largely disappeared.
“What shocked me, to be honest, is that for the first half of the time we were doing this project, I totally bought into the idea of age-related cognitive decline in healthy adults,” the lead author, Michael Ramscar, said by email. But the simulations, he added, “fit so well to human data that it slowly forced me to entertain this idea that I didn’t need to invoke decline at all.”

Can it be? Digital tools have confounded predigital generations; now here they are, coming to the rescue. Or is it that younger scientists are simply pretesting excuses they can use in the future to cover their own golden-years lapses?

In fact, the new study is not likely to overturn 100 years of research, cognitive scientists say. Neuroscientists have some reason to believe that neural processing speed, like many reflexes, slows over the years; anatomical studies suggest that the brain also undergoes subtle structural changes that could affect memory.

Still, the new report will very likely add to a growing skepticism about how steep age-related decline really is. It goes without saying that many people remain disarmingly razor-witted well into their 90s; yet doubts about the average extent of the decline are rooted not in individual differences but in study methodology. Many studies comparing older and younger people, for instance, did not take into account the effects of pre-symptomatic Alzheimer’s disease, said Laura Carstensen, a psychologist at Stanford University.

Dr. Carstensen and others have found, too, that with age people become biased in their memory toward words and associations that have a positive connotation — the “age-related positivity effect,” as it’s known. This bias very likely applies when older people perform so-called paired-associate tests, a common measure that involves memorizing random word pairs, like ostrich and house.

“Given that most cognitive research asks participants to engage with neutral (and in emotion studies, negative) stimuli, the traditional research paradigm may put older people at a disadvantage,” Dr. Carstensen said by email.

The new data-mining analysis also raises questions about many of the measures scientists use. Dr. Ramscar and his colleagues applied leading learning models to an estimated pool of words and phrases that an educated 70-year-old would have seen, and another pool suitable for an educated 20-year-old. Their model accounted for more than 75 percent of the difference in scores between older and younger adults on items in a paired-associate test, he said.

That is to say, the larger the library you have in your head, the longer it usually takes to find a particular word (or pair).

Scientists who study thinking and memory often make a broad distinction between “fluid” and “crystallized” intelligence. The former includes short-term memory, like holding a phone number in mind, analytical reasoning, and the ability to tune out distractions, like ambient conversation. The latter is accumulated knowledge, vocabulary and expertise.

“In essence, what Ramscar’s group is arguing is that an increase in crystallized intelligence can account for a decrease in fluid intelligence,” said Zach Hambrick, a psychologist at Michigan State University. In a variety of experiments, Dr. Hambrick and Timothy A. Salthouse of the University of Virginia have shown that crystallized knowledge (as measured by New York Times crosswords, for example) climbs sharply between ages 20 and 50 and then plateaus, even as the fluid kind (like analytical reasoning) is dropping steadily — by more than 50 percent between ages 20 and 70 in some studies. “To know for sure whether the one affects the other, ideally we’d need to see it in human studies over time,” Dr. Hambrick said.

Dr. Ramscar’s report was a simulation and included no tested subjects, though he said he does have several memory studies with normal subjects on the way.

For the time being, this new digital-era challenge to “cognitive decline” can serve as a ready-made explanation for blank moments, whether senior or otherwise.

It’s not that you’re slow. It’s that you know so much.

Kids’ Vitamins Often Exceed Recommended Doses

Young children who take vitamins may be consuming much greater levels than recommended of the nutrients, a new study suggests.

For the research, scientists reviewed the labels of nearly 200 dietary supplements marketed for children in two age groups: younger than 12 months, and 1 to 4 years old. The researchers determined the level of vitamins that children would consume if they used the product as directed. (Specifically, they looked at levels of vitamins A, C, D, E, K and B12, along with thiamin, riboflavin, niacin, folate, biotin and choline.)

Most products contained vitamin levels much greater than those recommended for children in a single day. For example, dietary supplements for children ages 1 to 4 contained, on average, about 300 percent of the daily recommended levels of vitamin A, thiamin and riboflavin, 500 percent of the recommended level of vitamin C and more than 900 percent of the recommended level of biotin

Vitamin D was the only vitamin that was present at or below recommended levels for both age groups.

It’s too soon to know whether these findings are concerning, said study researcher Michael Madden, an assistant professor at Lake Erie College of Osteopathic Medicine (LECOM) School of Pharmacy. That’s because few studies have explored the effects of greater-than-recommended levels of vitamins on infants and young children. So in many cases, the maximum amount of a vitamin that’s safe for a child to take is not known, the researchers said.

For this reason, the Institute of Medicine (IOM) recommends that young children not consume excess levels of certain vitamins, including vitamins K and B12, thiamin, riboflavin, folate, pantothenic acid and biotin. (Infants should not consume excess levels of most vitamins.) The IOM, part of the U.S. National Academies, is a national nonprofit that advised the nation on health.

There is also a concern that children’s bodies may lack the ability to handle excess amounts of certain vitamins, the IOM says.

The findings suggests that “much of the pediatric vitamin supplementation is not based on IOM recommendations and therefore represents wholesale over-supplementation,” the researchers wrote in the Jan. 27 issue of the journal JAMA Pediatrics.

Some studies have also shown that dietary supplements may contain levels of vitamins that are different from what’s listed on the label.

The American Academy of Pediatrics (AAP) says parents should speak with their pediatricians about whether their young child may need to take supplements. Toddlers who eat a balanced diet should be getting adequate levels of most vitamins and so should not need supplements, the AAP says. And very high doses of some vitamins, such as vitamin A, may even pose risks because they can accumulate in the body, the AAP says.

But some children may need supplements if, for instance, they have selective eating habits, and therefore don’t get adequate levels of vitamins through food, the AAP says.

In addition, the AAP recommends vitamin D supplements for infants, children and adolescents so that they consume 400 International Units (IU) of vitamin D per day.

Marijuana Use During Pregnancy Affects Babies’ Brain

Using marijuana during pregnancy could affect a baby’s brain development by interfering with how brain cells are wired, a new study in mice and human tissue suggests.

Researchers studied marijuana’s effects on mice and brain tissue from human fetuses, and found that the active ingredient in marijuana, THC, interferes with the formation of connections between nerve cells in the cerebral cortex, the part of the brain responsible for higher thinking skills and forming memories.

“Our advice is that [pregnant] mothers should avoid marijuana,”said neuroscientist Tibor Harkany of the Karolinska Institute in Sweden, and the Medical University of Vienna, in Austria, who led a study detailed today (Jan. 27) in the EMBO Journal. [11 Facts Every Parent Should Know About Their Baby’s Brain]

Harkany added that the effects of prenatal marijuana exposure could even last into adulthood. The drug could have direct effects, or it could sensitize the brain to future drug exposure or neuropsychiatric illnesses.

Pot during pregnancy

Previous studies have found that exposure to marijuana during pregnancy can increase a child’s risk of having cognitive deficits or psychiatric disorders.

While it is not exactly clear how marijuana may affect the fetal brain at a molecular level, it seems the brain may be particularly sensitive to THC (delta-9-tetrahydrocannabinol) during early development, when neurons are forming critical connections. Any drug that interferes with this development could be detrimental to the child, Harkany said.

In the study, Harkany and his colleagues tested marijuana’s effects in three ways: They grew brain cells from mice in the presence of THC, they injected pregnant mice with THC, and they studied the brains of electively aborted human fetuses whose mothers had used marijuana during pregnancy.

The researchers identified a specific protein in nerve cells, called Superior Cervical Ganglion 10 (SCG10), which is essential for normal brain wiring. They found lower levels of this protein in the brains of both human and mouse fetuses exposed to THC compared with individuals who weren’t exposed to THC, suggesting that marijuana exposure has a specific effect on the developing brain.

Marijuana and brain development

“Prenatal cannabis disrupts synapses [nerve connections] critical for higher order executive and cognitive function,” study researcher Yasmin Hurd, a neuroscientist at Mount Sinai Hospital in New York, told LiveScience in an email.

An increasing number of women of childbearing age are using marijuana, and this group should be made aware of the potential impact on the brain development of their children, she said.

Harkany added that pregnant women should avoid using marijuana use for medical purposes.

Previous long-term studies have shown that children exposed to marijuana in the womb may have an increased risk of showing cognitive effects, seeking out drugs, or having attention deficit disorder, anxiety or depression, according to the study.

Harkany and his colleagues didn’t study the effects of marijuana use prior to pregnancy, but he said the drug is cleared from the body in a period days, not months, and using it prior to conception is more likely to affect the likelihood of becoming pregnant than the fetus itself.

So far, Harkany said, no studies have compared the effect of marijuana to that of other drugs, such as alcohol, on fetal brain development.

Yoga May Reduce Fatigue in Breast Cancer Survivors

breast cancer

Yoga may help breast cancer survivors beat the debilitating fatigue and sleep problems that often follow toxic treatments such as chemotherapy and radiation, a new study shows.

Fatigue can be a big challenge for cancer survivors.

“Even some years out from breast cancer treatment, anywhere from 30 to 40 percent of women report substantial levels of fatigue,” said study author Janice Kiecolt-Glaser, a professor of psychology and psychiatry at Ohio State University in Columbus.

That may be due, in large part, to disrupted sleep. As many as 60 percent of cancer survivors say they have trouble sleeping, she noted, a rate that’s two to three times higher than their cancer-free peers.

The end result is that many cancer survivors end up trying to drag themselves through their days.

“And it’s a nasty downward spiral where increasing fatigue means less activity and less activity means increasing fatigue, so that over time less and less translates into greater frailty and decline,” Kiecolt-Glaser said.

Kiecolt-Glaser, who studies the health effects of stress, wanted to see if it was possible to stop that cycle.

She and her colleagues, including her husband and research collaborator, Ronald Glaser, recruited 200 women aged 27 to 76 who were new to yoga and had finished treatment for breast cancer within the last three years. They had to be at least two months past their last treatment and otherwise healthy to participate.

The women were randomly assigned to one of two groups. The first group practiced the gentle, flowing poses of Hatha yoga for two 90-minute sessions each week for three months. The second group was placed on a waiting list.

Before and after the study, all the women answered detailed questions about their energy and vitality, mental health, the kind of support they felt they were getting from friends and family, their sleep, how active they were and even their diet. Researchers also performed blood tests to measure markers of inflammation.

The differences weren’t immediately apparent. After three months of practice, women in the yoga group reported that they had more vitality and were sleeping better, compared to the group that was waiting to take the class.

And after their group sessions ended, most who were taking yoga gradually stopped practicing. Their physical activity went back to the level it was when they signed up for the study. Despite that, they continued to improve.

At the six-month mark, the women practicing yoga reported about 60 percent less fatigue than the women on the waiting list, and their measures of inflammation were 13 percent to 20 percent lower.

The longer they practiced yoga, the greater their improvements, Kiecolt-Glaser said.

12 foods that naturally whiten your teeth

We’ve all been told to avoid red wine, dark berries, and black coffee in our quests for pearly whites, but what about foods that actually brighten your smile? Try these natural solutions for a brilliant beam

Strawberries

They may be bright red, but malic acid, a chief component of this summery fruit, acts as a natural astringent to remove surface tooth discoloration, says Dr. Irwin Smigel, president of the American Society for Dental Aesthetics. Fresh, juicy strawberries taste great in any meal—salads, desserts, cereal—and are widely available at farmers markets this time of year, so getting your daily dose is both simple and delicious

 

Seeds and nuts

Chewing these lightly abrasive, hard foods rubs plaque and stains off the surface of teeth, says Dr. Matthew Messina, a spokesperson for the American Dental Association. Pop a few almonds for a mid-afternoon snack—they’re full of protein, healthy fats, and the crunch you need to get pearly whites.

Onions

Although they may not be the ideal pre-date snack, the notoriously bad-for-breath alliums could be beneficial to teeth. Because they’re colorless, they won’t cause surface stains, says Messina, adding that after eating them you’re more likely to brush—which is a surefire way to get whiter teeth.

Apples

The loud crunch you hear when you bite into this hard fruit may be annoying, but it’s also good for your choppers. Apples’ crispiness strengthens gums, and their high water content increases saliva production, dispersing and neutralizing colonies of bacteria that lead to bad breath and plaque, says Smigel.

 

Baking soda

Take a toothpaste break and try brushing with this common ingredient. Baking soda is a base, like bleach, notes Messina, and the “soda”—which is actually a form of salt—in this pantry staple is a mild abrasive that works to scrub off plaque and surface stains.

Celery and carrots

The same high water content that makes these veggies great for your waistline and your health also helps them whiten your teeth by stimulating saliva production, which aids in washing away food debris and strengthening gums, according to Smigel.

Broccoli

Unlike beets and cranberries, this crunchy vegetable doesn’t stay stuck to teeth, so it won’t cause unsightly surface stains, says Messina. Throw some raw broccoli into your lunch—the florets will scrub the surface of teeth, giving them a brief and natural midday

Cheese

Hard cheese, like the little blocks you get on those delicious appetizer trays, is full of calcium, which strengthens teeth and gums, explains Smigel. Plus, most cheeses are near colorless, meaning they won’t stain your teeth. So go ahead, order that cheese plate.

Oranges

This bright fruit contains citrus, an acid that can wear away tooth enamel if ingested in large doses, making teeth whiter—but at a cost, says Messina. So while we don’t recommend gulping down bags of oranges in the spirit of a bright smile, a juicy helping once in a while is good for your pearly whites, and thanks to loads of vitamin C, your overall health too.

Water

Drink lots of water to keep your mouth hydrated and your smile bright, advises Smigel, who recommends sipping and swishing between glasses of wine and when eating dark, pigmented foods to prevent staining. However, while water reduces the acidity in your mouth and the resulting damage to your enamel, Dr. Smigel warns against imbibing too much

Pears

Smigel recommends munching on a pear to neutralize pesky odor-causing and staining bacteria colonies on teeth. Increased saliva production brought on by this sweet, delicious fruit also washes away food debris, leaving teeth clean and sparkling.

Women should drink plenty of water in winter to keep cystitis at bay

Experts have warned that taking lesser amount of water during winters can give rise to major health problems such as cystitis or urinary tract infection, especially in women.

“Women are prone to cystitis because of their shorter urinary tract as compared to men. Women of all ages can acquire such infections but it is more with women who have just been married and women approaching menopause,” Malvika Sabharwal, head of department of gynaecologist and obstetrician, Nova Speciality Hospitals, was quoted as saying to IANS.

With women having higher risk of cystitis (eight times) than men, doctors recommend drinking at least 12 glasses of water a day to help flush out the infection and dilute the urine.

Up to 15 percent of women have cystitis each year and half of them have had cystitis at least once in their life.

“Women suffering from tuberculosis, diabetes mellitus, those who are pregnant and those who are sexually active are more vulnerable to cystitis,” added Sabharwal.

Doctors also stress that pregnant women should take special care not to keep their bladder empty.

“Pregnant women should try not to drink too much caffeine or acidic drinks such as orange juice as these can irritate the bladder. They should never keep their bladder empty as it can create an environment for bacteria to multiply,” Archana Dhawan Bajaj, gynaecologist and obstetrician at Nurture Clinic, told IANS.

“Burning sensation while urinating, frequent need to urinate but passing only small amounts or no urine, having pain in the lower back, dark smelly urine and even fever are the symptoms of cystitis,” adds Dhawan.

Blood can also pass along with urine but that can be detected only when the urine is tested.

“So to detect the severity of the infection, a simple microscopic culture of the urine has to be done,” Amita Shah, consultant gyanecologist, Columbia Asia Hospital, Gurgaon, told IANS.

However, doctors also advice microscopic urine examination once every three to six months.

“The treatment for cystitis includes addressing each episode promptly with a short course of antibiotics and sometimes, a regular dose of antibiotics for the long-term. However, if untreated, the infection can go from the bladder to the kidney,” added Shah.

To treat cystitis, doctors also advise daily doses of cranberry juices.

As preventive measures, doctors stress on maintaining hygiene.

“Self-hygiene is important and more important is that the washroom should also be cleaned and sanitised,” added Shah.

Drug-resistant TB spreading fast in Russia

scientists have found that tuberculosis strains in Russia carry mutations that not only make them resistant to antibiotics but also help them spread more effectively.

The latest study of TB cases in Russia indicates that rampant drug resistance may not be the only explanation for the TB rise in the region – biological factors also play a major role in it.

Researchers at Queen Mary University of London analysed 1,000 genomes from different TB isolates – the largest whole-genome study of a single bacterial species so far.

This enabled the team to identify previously unknown mutations linked to antibiotic resistance, as well as “compensatory mutations” that improve the ability of drug-resistant TB to spread.

Nearly half of the TB isolates were multi-drug resistant, which means that they were impervious to the two common first-line antibiotics that cure most TB infections.

Sixteen percent of these isolates also harboured mutations that made them impervious to “second-line” drugs.

These infections are more expensive to treat and patients who receive ineffective drugs are more likely to spread TB, said the research published in the journal Nature Genetics.

TB, which is caused by the bacterium Mycobacterium tuberculosis, exploded in Russia and other former Soviet nations in the early 1990s, after the collapse of the Soviet Union and its health system.

“It certainly adds an extra layer of worry, because one had assumed if you could solve ‘programmatic’ weaknesses, you would solve the problem of the drug-resistant TB,” stressed Francis Drobniewski, a microbiologist at Queen Mary University.

“Although we know the general story of TB drug resistance in Russia, these new findings are still shocking,” added Christopher Dye, an epidemiologist at the World Health Organisation (WHO) in Geneva.

According to Megan Murray, an epidemiologist at the Harvard School of Public Health in Boston, Massachusetts, the worst scenario is that the organisms are developing resistance, compensating for it, and evolving into something that’s new and different, that’s much less treatable.

Healthy lifestyle to improve oral health in diabetics

Diabetics, who are at a higher risk of suffering from oral health problems, can avoid these by adopting a healthy lifestyle.

Researchers at the University of Copenhagen have helped a large group of diabetics to markedly improve their oral health through health coaching.

“Diabetics are at a higher risk of suffering oral health issues like periodontitis and caries and other problems like dry mouth, fungal infections and poor wound healing,” said Ayse Basak Cinar, assistant professor at department of odontology at the university.

In all, 186 patients with type 2 diabetes participated in the study done in Turkey – the first in the world – to demonstrate the role of health coaching in improving dental health.

The patients with diabetes were divided into two groups.

One group was given traditional health information, for example a brochure on good dental hygiene.

The other group was offered motivational health coaching in the form of 3-6 sessions over a six-month period, focusing on diet, stress management and dental care, said the research published in the journal Clinical Oral Investigations.

“In patients who were given personal health coaching, biological markers for periodontitis – also known as loose teeth disease – were reduced by as much as 50 percent over a six-month period,” the research noted.

“The patients in the trial group saw a significant decline in long-range blood sugar levels, whereas figures for the control group were unchanged,” said.

“Health coaching is a resource-intensive intervention. However, dishing out brochures to patients with diabetes and thinking that this would help is also a costly approach for the society,” he added.

Laugh your way to good health

Laughter is the best medicine, is an age-old saying, and about 10,000 laughter clubs in India are a testimony to the fact that the therapy works.

A combination of group laughter exercises with yoga breathing, which allows people to laugh without cracking jokes, should be performed for at least 15 to 20 minutes, says Hasya yoga guru Jiten Kohi.

“The good chemical changes in the body can happen only if you spend time on it. The effects won’t be great if you finish your asanas quickly,” Kohi said.

“Such asanas are good for depressed people or those who lead stressful lives,” he added.

Rahul Chandhok, senior consultant psychiatrist at Gurgaon’s Fortis Hospital, pointed out that while work pressure has always been there, other factors like commuting and traffic are adding to the woes of people.

“In the metros one needs to commute for long hours; therefore, people are unable to give time to their families or even take out time for themselves. This causes stress,” Chandhok said.

Another reason is that everyone is competing with everyone for everything. In big cities, day-to-day life is getting more and more hectic and target, desire and deadline driven and the fight against stress overload multiplies.

“People end up comparing themselves to others, they want something that is way beyond their reach. All this causes stress,” Chandhok said.

“Unlike big cities, the smaller ones are at an advantage as far as distance is concerned. People don’t take long to commute from home to the workplace. But, yes, there are comparison factors that cause stress,” he added.

Kohi formed Hasya Yoga Kendra in 2000 because he felt that laughter – the healthiest gesture in people’s lives – is missing.

“As people grow up, they forget to laugh. Nowadays they just exercise. Don’t take it as exercise and laugh like a child. Take things lightly without pressurising your brain. This way you will be less stressful and that will help to stay fit in some way,” said Kohi.

His team holds around 52 yoga classes per day in areas like Model Town, Kalkaji and Janakpuri in the capital, apart from monthly sessions in Tihar Jail, in schools and at corporate houses.

With 300 centres in the country in places like Lucknow, Mumbai, Jaipur and Indore, Kohi gets better response in tier-II cities.

“People in small towns are more interested. Thousands of them turn up in the morning. In metropolitan cities, people lead busy lives; so maybe there are people who are able to join us in parks,” said Kohi, who believes it’s best to do asanas early morning in view of the relatively fresh air.

Apart from other recreational activities, laughter exercises help in improving the well-being of people.

“If you laugh wholeheartedly, your facial muscles will gain benefits and there will be a feeling of well-being, especially when you do such exercises in a group. Your body releases chemicals that help to relieve stress,” Ravindra Gupta, consultant in internal medicine at Gurgaon’s Columbia Asia Hospital, said.

However, he clarified that laughter can de-stress, but it can’t cure ailments.

“It can’t treat ailments. It can reduce blood pressure to some extent, but medication is required,” said Gupta.

Echoing this, Madan Kataria, founder of Laughter Yoga International, says laughter-based exercises help the immune system.

“When you laugh, the stress level goes down and you don’t easily fall sick,” said Kataria, who started his institution with his wife Madhuri in 1995 in Mumbai.

“In people with blood pressure, heart disease and diabetes, we have noticed a 50 percent improvement in their health due to laughter exercises. I am not saying it completely cures diseases, but there is reduction in medication,” he explained.

Kataria said there are around 10,000 laughter clubs in India and the demand is increasing in other parts of the world too.

“They are present in around 72 countries like Japan, Germany and US,” he said.

Chandhok said that yoga or meditation or laughter sessions are important for a healthy life, but medical treatment is equally vital.

“Treatment is essential. Complete it and then continue with these healthy activities,” he said.

So, step out and have a hearty laugh…..ha, ha, ha, ha!
