A smile is not just a smile, it can boost your memory!

May 6, 2014

Smile_memoryMay 6: A new study has revealed that humor and laughter can help lessen the damage that stress hormone cortisol has on memory and learning ability in the elderly. According to the researchers at Loma Linda University, there was a significant decrease in cortisol concentrations among both groups who watched a funny video and showed greater improvement in all areas of the memory assessment when compared to controls.

Gurinder Singh Bains said that their findings offer potential clinical and rehabilitative benefits that can be applied to wellness programs for the elderlyand the cognitive components, such as learning ability and delayed recall, become more challenging as people age and are essential to older adults for an improved quality of life.

The researchers said that the less stress one has the better their memory, as humor reduces detrimental stress hormones like cortisol that decrease memory hippocampal neurons, lowers the blood pressure, and increases blood flow and mood state.

The study revealed that the act of laughter-or simply enjoying some humor-increases the release of endorphins and dopamine in the brain, which provides a sense of pleasure and reward and the positive and beneficial neurochemical changes, in turn, make the immune system function better.

What are reasons for forgetfulness?

Forgetfulness, also called mild cognitive impairment, need not cause you much concern if it happens once in a while, but if you are forgettings quite often like Vicky, then it’s time to delve deeper into the cause of your forgetfulness.

Age, medical conditions, and emotional problems – all of these can contribute to forgetfulness. Most memory problems can be treated, so see your doctor if you or your loved one tend to forget stuff often. Here’s a 101 on the causes of forgetfulness.

1. Ageing

If you are in your 50s or 60s or maybe 70s, you may suddenly feel you are losing it. You stand in front of your refrigerator and you just don’t seem to recollect what it was that you wanted to take out of it. Or, you are discussing books with your friend and you are trying very hard to remember the title of the book you were reading the day before. These are the memory changes during normal ageing and you do not have to be alarmed, but they may also be the beginning symptoms of Alzheimer’s.

We start forgetting stuff because as we age the nerve impulses that travel between cells and cell membrane in the brain slows down. This decline in cognitive ability is not abrupt and progresses imperceptibly over decades, say scientists from the Johns Hopkins School of Medicine. It is natural and there is not much you can do to stop the progression of memory lapses other than try and socialize more and do things that help keep your memory sharp and you alert.

The practice of washing your hands for 20 seconds is one of the best preventive measures you can take to avoid the spread of any virus including coronavirus as recommended by the WHO.

The modern day concept of handwashing was introduced by Hungaraian doctor Ignaz Semmelweis, in 19-th century Vienna. Semmelweis proposed the practice of washing hands with chlorinated lime solutions in 1847 while working in the city's general hospital.

Decades later, in the modern times too the practise has not lost it's relevance. To connect with savvy consumers the message is being sent through social media? But social media can also be a dark place where misinformation is rampant; consumers can end up being misguided and compromised on sensitive issues like health and hygiene.

Dettol, recently kickstarted its #HandWashChallenge on TikTok aiming to raise awareness on four simple steps of handwashing. Strategically aimed at creating awareness among audience, a unique song has been created pairing it extremely well with the hashtag #HandWashChallenge. The hashtag filter has a branded Dettol strip across the top with the hashtag and names the steps involved in washing hands. The user can dance out the steps to the challenge and share it with their friends to further amplify the message on hygiene and safety.

Commenting on the same, Pankaj Duhan, Chief Marketing Officer, RB Health South Asia said, "We are elated with the response to the #HandWashChallenge, it has definitely become one of the most successfully led initiatives by any of our brands at RB. Understanding the consumer's mindset is of the utmost importance to us, therefore our campaign communication is built in a way that creates meaningful conversations to drive awareness amongst consumers. The participation by TikTok users across India has helped deliver the right message in a more engaging and interactive manner.

"I personally would like to encourage more and more people to join this global health & hygiene educational exercise. Together, let us all build a healthier nation, four steps at a time."

He further said, "Over the past couple of weeks we have witnessed a lot of misinformation floating around hygiene practices, especially over the internet. Realizing the gravity of the issue and being the responsible brand, we felt it was our prerogative to initiate this awareness campaign."

The campaign witnessed several quirky activities on each day leading to increased consumer interest. Joining the force were some of Bollywood's popular celebrities like Kartik Aaryan and Urvashi Rautela among several other TikTok influencers who have millions of followers on the platform. As part of Phase II, Dettol plans to take the challenge global by encouraging more users to participate while the audience worldwide.

The challenge has witnessed over 18 Billion views and generated over 123K user participation videos in one week of starting the campaign.

High-protein diets may help people lose weight and build muscle, but there is a downside to it --a greater heart attack risk. Researchers now report that high-protein diets boost artery-clogging plaque.

The research in mice showed that high-protein diets spur unstable plaque -- the kind most prone to rupturing and causing blocked arteries.

More plaque buildup in the arteries, particularly if it's unstable, increases the risk of heart attack.

"There are clear weight-loss benefits to high-protein diets, which has boosted their popularity in recent years," said senior author Babak Razani, associate professor at Washington University School of Medicine in St. Louis, Missouri.

"But animal studies and some large epidemiological studies in people have linked high dietary protein to cardiovascular problems. We decided to take a look at whether there is truly a causal link between high dietary protein and poorer cardiovascular health," Razani added.

The researchers studied mice who were fed a high-fat diet to deliberately induce atherosclerosis, or plaque buildup in the arteries.

Some of the mice received a high-fat diet that was also high in protein. And others were fed a high-fat, low-protein diet for comparison.

The mice on the high-fat, high-protein diet developed worse atherosclerosis -- about 30 per cent more plaque in the arteries -- than mice on the high-fat, normal-protein diet, despite the fact that the mice eating more protein did not gain weight, unlike the mice on the high-fat, normal-protein diet.

"A couple of a scoop of protein powder in a milkshake or smoothie adds something like 40 grams of protein -- almost equivalent to the daily recommended intake," Razani said.

"To see if protein has an effect on cardiovascular health, we tripled the amount of protein that the mice receive in the high-fat, high-protein diet -- keeping the fat constant. Protein went from 15 per cent to 46 per cent of calories for these mice".

Plaque contains a mix of fat, cholesterol, calcium deposits and dead cells. Past work by Razani's team and other groups has shown that immune cells called macrophages work to clean up plaque in the arteries.

But the environment inside plaque can overwhelm these cells, and when such cells die, they make the problem worse, contributing to plaque buildup and increasing plaque complexity.

"In mice on the high-protein diet, their plaques were a macrophage graveyard," Razani informed.

To understand how high dietary protein might increase plaque complexity, Razani and his colleagues also studied the path protein takes after it has been digested -- broken down into its original building blocks, called amino acids.

"This study is not the first to show a telltale increase in plaque with high-protein diets, but it offers a deeper understanding of the impact of high protein with the detailed analysis of the plaques," said Razani.

"This work not only defines the critical processes underlying the cardiovascular risks of dietary protein but also lays the groundwork for targeting these pathways in treating heart disease," he added.

17-year-old Pratyusha Jha, wakes up scrambling for newspapers these days to look for any news about her pending board exams and is anxious about what the future has in store for her.

Similar concerns are shared by Bipin Kumar, a class 12 student, who says the announcement of board exams from July 1 to 15 brought limited clarity as the larger questions remain unanswered.

The COVID-19 lockdown, came with a different set of concerns for class 12 students, whose board exams were postponed midway following the outbreak of coronavirus, putting on hold their future plans as well.

"Everyday I have been looking for news about the exams and about entrance exam dates. I feel unfortunate that this happened during the year I was supposed to take the big college leap. I don't want my future decisions to be shaped by this very year as what I opt to study now will remain with me lifelong," Pratyusha told PTI.

Ending some uncertainty for students, HRD Minister Ramesh Pokhriyal 'Nishank' on Friday announced that the pending class 10 and 12 board exams will be held from July 1 to 15. While class 12 exams will be conducted across the country, the class 10 exams are only pending in North East Delhi where they were affected due to the law and order situation.

"The anxiety doesn't end here, there is no date sheet yet. What will be the modalities of exams, how will we reach centres, what protocols have to be followed, there is no clarity on that. My friends and I keep calling our school teachers and also the CBSE helpline to seek some clarity," Bipin Kumar said.

Vaibhav Sharma, a class 12 student in Gurgaon said, "There is no clarity yet. I wanted to apply for DU, but now that the exams are taking place in July when will the results be declared, when will cut offs be announced. If I don't get a good college here, will I be able to travel to different cities for admission, nothing is known yet."

Similarly, for the students in northeast Delhi, the wait for the exams has become a "test of patience" as they were postponed first in the area due to law and order situation, and later due to the coronavirus outbreak, resulting in a four-month-long wait for the exams.

"It has become an endless wait and now I don't feel like studying too. Right from childhood, we are taught that board exams are too crucial and have to be focussed at least two years in advance. But now, it is a different picture altogether," Rani Kumari, a resident of Chandbagh said.

Universities and schools across the country have been closed and exams postponed since March 16 when the Centre announced a countrywide classroom shutdown as one of the measures to contain the COVID-19 outbreak.

Later, a nationwide lockdown was announced on March 24, which has now been extended till May 17.

The board was not able to conduct class 10 and 12 exams on eight examination days due to the coronavirus outbreak. Further, due to the law and order situation in North East Delhi, the board was not able to conduct exams on four examination days, while a very small number of students from and around this district were not able to appear in exams on six days.

The board had last month announced that it will only conduct pending exams in 29 subjects which are crucial for promotion and admission to higher educational institutions. The modalities of assessment for the subjects for which exams are not being conducted will be announced soon by the board.

The schedule has been decided in order to ensure that the board exams are completed before competitive examinations such as engineering entrance JEE-Mains, which is scheduled from July 18-23, and medical entrance exam NEET, which is scheduled on July 26.

The University Grants Commission (UGC) has issued guidelines to universities that new academic session for freshers will begin from September while for the existing students from August.
