Drinking hot tea daily may reduce glaucoma risk: study

The coronavirus can stay aloft for hours in tiny droplets in stagnant air, infecting people as they inhale, mounting scientific evidence suggests.

This risk is highest in crowded indoor spaces with poor ventilation, and may help explain superspreading events reported in meatpacking plants, churches and restaurants.

It’s unclear how often the virus is spread via these tiny droplets, or aerosols, compared with larger droplets that are expelled when a sick person coughs or sneezes, or transmitted through contact with contaminated surfaces, said Linsey Marr, an aerosol expert at Virginia Tech.

Aerosols are released even when a person without symptoms exhales, talks or sings, according to Marr and more than 200 other experts, who have outlined the evidence in an open letter to the World Health Organization.

What is clear, they said, is that people should consider minimizing time indoors with people outside their families. Schools, nursing homes and businesses should consider adding powerful new air filters and ultraviolet lights that can kill airborne viruses.

What does it mean for a virus to be airborne?

For a virus to be airborne means that it can be carried through the air in a viable form. For most pathogens, this is a yes-no scenario. HIV, too delicate to survive outside the body, is not airborne. Measles is airborne, and dangerously so: It can survive in the air for up to two hours.

For the coronavirus, the definition has been more complicated. Experts agree that the virus does not travel long distances or remain viable outdoors. But evidence suggests it can traverse the length of a room and, in one set of experimental conditions, remain viable for perhaps three hours.

How are aerosols different from droplets?

Aerosols are droplets, droplets are aerosols — they do not differ except in size. Scientists sometimes refer to droplets fewer than 5 microns in diameter as aerosols. (By comparison, a red blood cell is about 5 microns in diameter; a human hair is about 50 microns wide.)

From the start of the pandemic, the WHO and other public health organizations have focused on the virus’s ability to spread through large droplets that are expelled when a symptomatic person coughs or sneezes.

These droplets are heavy, relatively speaking, and fall quickly to the floor or onto a surface that others might touch. This is why public health agencies have recommended maintaining a distance of at least 6 feet from others, and frequent hand washing.

But some experts have said for months that infected people also are releasing aerosols when they cough and sneeze. More important, they expel aerosols even when they breathe, talk or sing, especially with some exertion.

Scientists know now that people can spread the virus even in the absence of symptoms — without coughing or sneezing — and aerosols might explain that phenomenon.

Because aerosols are smaller, they contain much less virus than droplets do. But because they are lighter, they can linger in the air for hours, especially in the absence of fresh air. In a crowded indoor space, a single infected person can release enough aerosolized virus over time to infect many people, perhaps seeding a superspreader event.

For droplets to be responsible for that kind of spread, a single person would have to be within a few feet of all the other people, or to have contaminated an object that everyone else touched. All that seems unlikely to many experts: “I have to do too many mental gymnastics to explain those other routes of transmission compared to aerosol transmission, which is much simpler,” Marr said.

Can I stop worrying about physical distancing and washing my hands?

Physical distancing is still very important. The closer you are to an infected person, the more aerosols and droplets you may be exposed to. Washing your hands often is still a good idea.

What’s new is that those two things may not be enough. “We should be placing as much emphasis on masks and ventilation as we do with hand washing,” Marr said. “As far as we can tell, this is equally important, if not more important.”

Should I begin wearing a hospital-grade mask indoors? And how long is too long to stay indoors?

Health care workers may all need to wear N95 masks, which filter out most aerosols. At the moment, they are advised to do so only when engaged in certain medical procedures that are thought to produce aerosols.

For the rest of us, cloth face masks will still greatly reduce risk, as long as most people wear them. At home, when you’re with your own family or with roommates you know to be careful, masks are still not necessary. But it is a good idea to wear them in other indoor spaces, experts said.

As for how long is safe, that is frustratingly tough to answer. A lot depends on whether the room is too crowded to allow for a safe distance from others and whether there is fresh air circulating through the room.

What does airborne transmission mean for reopening schools and colleges?

This is a matter of intense debate. Many schools are poorly ventilated and are too poorly funded to invest in new filtration systems. “There is a huge vulnerability to infection transmission via aerosols in schools,” said Don Milton, an aerosol expert at the University of Maryland.

Most children younger than 12 seem to have only mild symptoms, if any, so elementary schools may get by. “So far, we don’t have evidence that elementary schools will be a problem, but the upper grades, I think, would be more likely to be a problem,” Milton said.

College dorms and classrooms are also cause for concern.

Milton said the government should think of long-term solutions for these problems. Having public schools closed “clogs up the whole economy, and it’s a major vulnerability,” he said.

“Until we understand how this is part of our national defense, and fund it appropriately, we’re going to remain extremely vulnerable to these kinds of biological threats.”

What are some things I can do to minimize the risks?

Do as much as you can outdoors. Despite the many photos of people at beaches, even a somewhat crowded beach, especially on a breezy day, is likely to be safer than a pub or an indoor restaurant with recycled air.

But even outdoors, wear a mask if you are likely to be close to others for an extended period.

When indoors, one simple thing people can do is to “open their windows and doors whenever possible,” Marr said. You can also upgrade the filters in your home air-conditioning systems, or adjust the settings to use more outdoor air rather than recirculated air.

Public buildings and businesses may want to invest in air purifiers and ultraviolet lights that can kill the virus. Despite their reputation, elevators may not be a big risk, Milton said, compared with public bathrooms or offices with stagnant air where you may spend a long time.

If none of those things are possible, try to minimize the time you spend in an indoor space, especially without a mask. The longer you spend inside, the greater the dose of virus you might inhale.

Bergen, Mar 5: Divorce of parents may impact the academics of children negatively, suggests a new study.

According to the study, parental divorce is associated with a lower grade point average (GPA) among adolescents, with a stronger association seen in teens with more educated mothers.

The study was published in the journal PLOS ONE.

Children and adolescents with divorced or separated parents are known to do less well in school than adolescents with nondivorced parents and to be less well-adjusted, on average, across a spectrum of physical and mental health outcomes.

In the new study, researchers used data from the youth@hordaland study, a population-based survey of adolescents aged 16-19 conducted in the spring of 2012 in Hordaland County, Norway.

19,439 adolescents were invited to participate and 10,257 agreed; of those, 9,166 are included in the current study.

Overall, adolescents with divorced parents had a 0.3 point lower GPA (standard error 0.022, p<0.01) than their peers.

Controlling for parental education reduced the effect by 0.06 points to 0.240 (SE 0.021, p<0.01). This heterogeneity was predominantly driven by maternal education levels, the researchers found.

After controlling for paternal education and income measures, divorce was associated with a 0.120 point decrease in GPA among adolescents whose mothers had a secondary school education level; a 0.175 point decrease when mothers had a Bachelor's level education; and a 0.209 point decrease when mothers had a Master's or PhD level education (all estimates relative to adolescents with a mother who had a basic level of education, such as ISCED 0-2).

Due to the cross-sectional structure of the study, researchers could not investigate specific changes between pre- and post-divorce family life, and future studies are needed to investigate potential mechanisms (such as reduced parental monitoring or school-involvement) which might drive this finding.

Nonetheless, this study provides new evidence that the negative association between divorce and teens' GPA is especially strong in families with more educated mothers.

"Among Norwegian adolescents, parental divorce was hardly associated with GPA among youth whose parents have low educational qualifications. In contrast, among adolescents with educated or highly educated mothers, divorce was significantly associated with lower GPA," said the authors.

An uncertain prognosis, severe shortage of resources and the imposition of unfamiliar public health measures that infringe on personal freedoms along with large and growing financial losses are undoubtedly contributing to the widespread psychological and emotional distress associated with COVID-19.

The COVID-19 pandemic has forced millions of people to work from home world-wide. Today, due to constant exposure to increasing numbers, an intense fear of contamination have a massive psychological impact on people who are working from home.

Fabricating a Positive Workstation

There should be a separate workstation so that one can concentrate while working from home. It would be great if the work desk is stationed somewhere near a window or a balcony door so that one can welcome sunlight, fresh air and a view of plants & birds during the day. Try to have an ergonomic setting of your table and chair so that you keep your posture right while working the whole day. Keeping one or two indoor plants near your work desk will help to make it interesting.

Keep your laptop charger wires and other stuff neatly on your desk to avoid overwhelming yourself. Motivation quotes around you will help to make you overall positive. Keep your notes diary and pen handy at your desk. It will always helps to keep some colorful artifacts around you to make the atmosphere a little cheerful.

Avoid the pilling up files and unnecessary stationery at your workstation. Clutter is responsible for the confusion and problems all around and it leads to distraction; thus, a clean desk reflects power which enhances positivity and creates a tranquil workspace that will help your mind focus on productivity. It is important to declutter your work desk once in a few days because physical clutter translates to mental clutter.

Gratitude Notes in workstation and how to manifest

It is a great morning practice to write at least five things you are grateful for. It helps to shift the focus from negative to positive, from scarcity to abundance. One can write gratitude statements on Post it notes and put them at the work daily. This will raise the vibrations and help you stay grounded and positive. You can also compile affirmations and prayers that you resonate. Whenever you take work breaks, it is a good idea to read these.

Crystals to imbibe positivity at workstation

Selenite is a great crystal to spread light and positivity around. Black tourmaline absorbs negativity and is great to shield you from it during lockdown. Shungite is a great crystal to reduce the effects of electromagnetic radiations around you. You can place it near your wifi router, laptop and other devices to reduce the EMF pollution effects on you and your family. Clear quartz is great for energizing you after a tiring meeting. Just hold it in your left hand with eyes closed for five minutes and visualise beautiful energy entering your body and soul.

You can combine this exercise by holding black tourmaline in your right hand and visualize all the tiredness and unwanted energy draining into the black tourmaline. Tiger eye is very effective in eliminating the scattered brain and it allows us to make confident decisions. Green Aventurine neutralizes stress and anxiety from work, allowing us to keep calm.

Lepidolite is known as the Peace Stone, making it one of the best crystals for peace. It improves our overall mood, calms us, soothes us, and reduces our anxiety with a peaceful sense of happiness.

Sodalite is a great crystal for peace because it turns fear and stress into peaceful feelings. It also helps in better communication and can help while making crucial presentations & meetings.

Fluorite is great for healing and rejuvenating the mind and body. You can close your eyes and sit quietly with Fluorite while imagining your body being filled with an incredible energy that puts you at ease with yourself and the world.

Pyrite, also known as abundance stone, is great to put over your business card to manifest abundance at work.

Don't forget to clean your crystals regularly to harness their maximum energy.

Meditate, Do Pranayam and Stay Hydrated!

It is important to take short breaks to maintain productivity at work. Being summer, it is a good idea to get up for a water break once in 30 minutes at least. Even if you keep a water bottle alongside you, walking to the kitchen for water will help your physical body get some much needed movement.

Few iterations of square breathing once in two hours is a great way to boost your mind and body. Square breathing is basically the sequence of inhalation - holding breath - exhalation - holding breath - all for equal time spans. So you can count mentally 1 to 4 in inhalations, then again counting 1 to 4 as you hold your breath, and so on and so forth.

You can also chant any mantra while taking a work break for 1 or 2 minutes. While attending online meetings, where there is nothing much your hands are doing, you can utilize that time to do Yoga Hast/Hand Mudras and harness their energies. Pran Mudra is one of the best options to practice while attending meetings or reading articles, where your hands are free essentially.
