World Environment Day: Use biodegradable pads, wear organic jeans to save environment

WORLD ENVIRONMENT DAY

New Delhi, June 5: Make your contribution in saving the Earth by using biodegradable sanitary pads, organic jeans and 100 per cent vegan skincare products.

With Tuesday being the World Environment Day, make a conscious effort and change the dynamics of the depleting environment.

Manohar Kamath, Head at Myntra Fashion Brands, who has introduced organic jeans to the brand’s collection, has given few inputs:

* Use 100 per cent organic cotton jeans, recycled poly jeans where each pair uses between 9-21 bottles worth of plastic for production, and reduced water jeans where each pair saves on 36 litres of water.

Shankar Prasad, Founder at Plum, and Cyril Feuillebois, Founder at Kronokare, have given inputs on why it will be good to switch to organic and vegan skincare products:

* The products we are choosing for self care and better health are exposing us to even more chemicals and toxins causing more harm than good to our quality of living, health and wellness. However, a subtle shift in the consumer mindset is discernible, with more and more people are opting for chemical free, organic, natural or vegan products.

* From the product to the packaging, the products should be animal cruelty-free and vegetarian.

* Remember to carry a cloth bag to bring home the groceries in and re-use the aluminium foil leftover from lunch.

Tanvi Johri, Founder at Carmesi, an all-natural sanitary pads brand, says biodegradable sanitary napkins, which are made of sustainable materials like bamboo fiber and corn starch, decompose within 6-12 months of being disposed off.

“Hence, it’s high time that we wake up to the idea of using completely biodegradable sanitary napkins that offer a sustainable solution to the tons of non-biodegradable waste generated every year due to improper disposal of sanitary waste,” Johri said.

Tanya Eldred-Bhat, Fashion Consultant, The Open Trunk, says adopting eco-friendly methods have become the “need of the hour for this glamourous world to sustain”.

“Using natural materials such as the eucalyptus fibre not only minimises the use of toxic chemicals, but also is a great example of how one can make the optimum use of natural resources, without causing any destruction,” said Eldred-Bhat.

How fasting can improve your overall health

Fasting may not be just a religious or political practice. It may actually protect you against age-related diseases and improve your overall health, researchers say.

The study, led by a team from the University of California-Irvine (UCI), found that fasting affects circadian clocks in the liver and skeletal muscle, causing them to rewire their metabolism, which can ultimately lead to improved health and protection against age-related diseases.

The circadian clock operates within the body and its organs as intrinsic time-keeping machinery to preserve homeostasis in response to the changing environment.

And, while food is known to influence clocks in peripheral tissues, it was unclear until now how the lack of food influences clock function and ultimately affects the body.

“We discovered fasting influences the circadian clock and fasting-driven cellular responses, which together work to achieve fasting-specific temporal gene regulation,” said lead author Paolo Sassone-Corsi, Professor of Biological Chemistry at UCI.

“Skeletal muscle, for example, appears to be twice as responsive to fasting as the liver,” Sassone-Corsi added.

The research, detailed in the Cell Reports journal, was conducted using mice, which were subjected to 24-hour periods of fasting.

While fasting, the mice exhibited a reduction in oxygen consumption (VO2), respiratory exchange ratio (RER), and energy expenditure, all of which were completely abolished by refeeding, which parallels results observed in humans.

“The reorganisation of gene regulation by fasting could prime the genome to a more permissive state to anticipate upcoming food intake and thereby drive a new rhythmic cycle of gene expression. In other words, fasting is able to essentially reprogram a variety of cellular responses,” Sassone-Corsi said.

“Therefore, optimal fasting in a timed manner would be strategic to positively affect cellular functions and ultimately benefiting health and protecting against age-associated diseases.”

This study opens new avenues of investigation that could ultimately lead to the development of nutritional strategies to improve health in humans.

Scientists decode different ways human face conveys happiness

While disgust needs just one facial expression to get its point across throughout the world, happiness has 17 — a testament to the many varied forms of cheer, delight and contentedness, finds a study.

On the other hand, to convey fear humans use three expressions, four to convey surprise, and five each to convey sadness and anger.

The researchers explained that the differences in how our faces convey happiness can be as simple as the size of our smiles or the crinkles near our eyes.

“This was delightful to discover, because it speaks about the complex nature of happiness,” said Aleix Martinez, Professor at The Ohio State University.

“Happiness acts as a social glue and needs the complexity of different facial expressions; disgust is just that: disgust,” Martinez said.

The study showed that humans can configure their faces in thousands and thousands of ways to convey emotion — from anger to sadness to riotous joy — but only 35 expressions are actually similar across cultures.

For the study, published in the journal IEEE Transactions on Affective Computing, the team assembled a list of 821 English words that describe feelings and then used those words to mine the Internet for images of people’s faces.

The words were translated into Spanish, Mandarin Chinese, Farsi and Russian, and plugged into search engines popular in 31 countries across North America, South America, Europe, Asia and Australia to download an equal number of images.

They found approximately 7.2 million images of facial expressions across a variety of cultures.

Based on computer algorithms, the team found that the human face is capable of configuring itself in 16,384 unique ways, combining different muscles in different ways.

The researchers took the 7.2 million images their searches yielded and sorted them into categories, looking for those that expressed emotion across cultures. They found only 35.

Too much or too less sleep can increase heart disease risk

sleep

London, Jan 15: Men who sleep less than six hours a night may be at an increased risk of cardiovascular disease compared to those who sleep between seven and eight hours, a new study suggests.

The study showed that poor quality sleep of less than six hours increases the risk of atherosclerosis by 27 per cent compared to seven to eight hours of sleep.

Atherosclerosis refers to the build-up of fats, cholesterol and other substances in and on the artery walls throughout the body.

On the other hand, women who slept more than eight hours a night had an increased risk of atherosclerosis.

“Cardiovascular disease is a major global problem and we are preventing and treating it using several approaches, including pharmaceuticals, physical activity and diet,” said Jose M. Ordovas, researcher at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) in Madrid.

“But the study emphasizes we have to include sleep as one of the weapons we use to fight heart disease — a factor we are compromising every day,” he added.

For the study, published in the Journal of the American College of Cardiology, the team included 3,974 bank employees among which all were without known heart disease and two-thirds were men.

In addition, alcohol and caffeine consumption were found to cause short and disrupted sleep.

“Many people think alcohol is a good inducer of sleep, but there’s a rebound effect. If you drink alcohol, you may wake up after a short period of sleep and have a hard time getting back to sleep. And if you do get back to sleep, it’s often a poor-quality sleep,” Ordovas said.

Lack of sleep has been known to raise the risk of cardiovascular disease by increasing heart disease risk factors such as glucose levels, blood pressure, inflammation and obesity.
