Skin exposure to UVB (Ultra Violet-B) radiation from the Sun can alter the gut microbiome in humans — possibly via vitamin D which can help explain the protective role of UVB in inflammatory diseases like Multiple Sclerosis and Inflammatory Bowel Disease.

Sun exposure, vitamin D levels and the mix of bacteria in our gut are each associated with risk of inflammatory conditions like MS and IBD, said scientists from University of British Columbia.

Exposure to UVB in sunlight is well-known to drive vitamin D production in the skin, and recent studies suggest that vitamin D alters the human gut microbiome.

However, that UVB, therefore, causes gut microbiome changes, via vitamin D production, has so far been shown only in rodents.

In a new clinical pilot study, researchers tested the effect of skin UVB exposure on the human gut microbiome.

Healthy female volunteers were given three, one-minute sessions of full-body UVB exposure in a single week.

Before and after treatment, stool samples were taken for analysis of gut bacteria – as well blood samples for vitamin D levels.

Skin UVB exposure significantly increased gut microbial diversity, but only in subjects who were not taking vitamin D supplements.

“Prior to UVB exposure, these women had a less diverse and balanced gut microbiome than those taking regular vitamin D supplements,” reported Professor Bruce Vallance, who led the University of British Columbia study.

“UVB exposure boosted the richness and evenness of their microbiome to levels indistinguishable from the supplemented group, whose microbiome was not significantly changed”.

Published in Frontiers in Microbiology, the analysis suggests that vitamin D mediates the change — which could help explain the protective effect of UVB light in inflammatory diseases like MS and IBD.

The largest effect was an increase in the relative abundance of “Lachnospiraceae” bacteria after the UVB light exposures.

This indicates that vitamin D at least partly mediates UVB-induced gut microbiome changes.

The study is not designed to show the exact mechanism by which the microbiome changes occur, but both UVB and vitamin D are known to influence the immune system.

“It is likely that exposure to UVB light somehow alters the immune system in the skin initially, then more systemically, which in turn affects how favourable the intestinal environment is for the different bacteria,” suggests Vallance.

The results have implications for people who are undergoing UVB phototherapy, said scientists. (IANS)

Apple has managed to reopen nearly 256 retail stores out of more than 500 worldwide, as it aims to safely restart operations.

Apple closed all its retail stores outside Greater China in March as COVID-19 pandemic spread. All the Apple stores in Greater China are now open.

“In China, and later around the world, we were one of the first companies to close our stores. In Greater China, we saw the importance of swift action — and the critical importance of social distance — to slow the virus’ spread,” according to Apple’s head of retail Deidre O’Brien.

Apple is taking some additional steps in most places. Throughout the day, Apple is conducting enhanced deep cleanings that place special emphasis on all surfaces, display products, and highly trafficked areas.

“Face coverings will be required for all of our teams and customers, and we will provide them to customers who don’t bring their own. Temperature checks will be conducted at the door, and posted health questions will screen for those with symptoms — like cough or fever — or who have had recent exposure to someone infected with COVID-19,” O’Brien elaborated.

Oil pulling is regarded as an ancient Ayurveda treatment that dates back to more than 3,000 years.

Considered as a detoxification therapy, it is done by taking a spoonful of cold pressed virgin oil (preferably coconut oil) and swishing it in your mouth for about 5 minutes, similar to using a mouthwash. The purpose of oil pulling is to swish the oil around in your mouth, between the teeth to get rid of bacteria in the mouth, spit it out and immediately rinse with some warm water.

Nutritionist Sheryl Salis shares how oil pulling that can help improve your immunity, uses of virgin coconut oil and the method of oil pulling:

Oil pulling is an alternative health practice gaining traction in recent times not only for oral health but also as an immunity boosting measure. As the mouth is a home to millions of microbes including bacteria, the oil pulling process helps get rid of these bacteria through swishing oil in the mouth and in-between the teeth. Swishing the oil for a prolonged period cleanses the mouth and decreases the bacterial load. Not only does this promote oral hygiene, this technique aids in overall health and well-being.

With the COVID-19 pandemic spread across the globe, it is recommended to build and maintain a strong immune system to help combat the risk of being infected. While external precautionary measures like sanitizing and washing hands are essential, maintaining basic hygiene measures and eating healthy to build one’s immunity is of utmost importance.

Using virgin coconut oil to build immunity

Cold pressed virgin coconut oil is a superfood recommended for its myriad health benefits; it is a rich source of naturally occurring Lauric acid and contains Vitamin E which helps to improve body’s immunity. The medium Chain Fatty Acids (MCFAs) that contain lauric acid and caprylic acid strengthens the immune system and has anti-viral properties. Therefore, Adding 2 spoons of virgin coconut oil to the diet every day can help improve the immunity and maintain a healthy, holistic lifestyle.

In most Indian household’s, virgin coconut oil is a staple for consumption and beauty practices and is slowly making its way in the mainstream wellness community for oil pulling. Known for its immune boosting properties, virgin coconut oil can be introduced as an effective technique into your heath regime.

Covid-19 to Cause Lasting Physical and Mental Health Consequences Worldwide

Researchers warn that the pandemic is likely to cause profound health issues globally

The coronavirus pandemic’s life-altering effects are likely to result in lasting physical and mental health consequences for several people, warn researchers.

For the findings, published in the journal Proceedings of the National Academy of Sciences, the research team studied low-income women from New Orleans in the US, who were surveyed the year prior to, and at intervals after Hurricane Katrina struck in 2005.

The women reported a range of traumatic experiences during Katrina, many of which are similar to those now occurring during the pandemic, including bereavement, lack of access to medical care and scarcity of medications.

The research showed that at one, four and 12 years after the hurricane, the exposures most strongly associated with post-traumatic stress, psychological distress, general health and physical health symptoms were those most common to the current pandemic.

The pandemic continues to cause widespread death and sickness, as well as job loss and severe economic hardship for many.

“This pandemic is likely to have profound short- and long-term consequences for physical and mental health,” said study researcher Sarah Lowe, Assistant Professor at Yale University in the US.

“These impacts are likely to be even larger than what we have seen in previous disasters like Hurricane Katrina, given the distinctive qualities of the pandemic as a disaster,” Lowe added.

The study did not include other exposures that are taking place during the pandemic, such as financial losses and unemployment, which are also likely to have additional and significant impacts on public health.

The results suggest that, in addition to promoting actions to reduce COVID-19 transmission and addressing longstanding health disparities contributing to COVID-19 morbidity and mortality, public health measures should also prevent and mitigate exposures that will have indirect effects on mental and physical health.

This includes preventing lapses in medical care and medication access. Additionally, another key exposure in the study was fear for one’s own safety and the safety of others.

As such, public health messaging should provide tips for managing anxiety and fear, in addition to promoting efforts to increase safety from COVID-19 transmission.

“Supplemental health services should be provided to those who are bereaved or are experiencing clinically significant fear and anxiety-related the pandemic,” Lowe said.

“This study represents a step toward disentangling the health consequences of disasters, while also recognising more longstanding factors that contribute to health disparities,” she wrote.

Recently, another study, published in The Lancet Psychiatry journal, revealed that people taken ill by coronavirus infections may experience psychiatric problems while hospitalised and potentially after they recover. (IANS)
