Hydrogen peroxide based cleaning products could raise the levels of that toxin to 610 times its level in fresh air.  Researchers from Syracuse University and the University of Saskatchewan measured gaseous hydrogen peroxide in a chamber designed to simulate residential settings.

Hydrogen peroxide-containing disinfectants represent more than 10% of products sold in Canada, and some 168 such products are on the market.  Excessive exposures can irritate the lung, skin, and eyes.  This is a particular risk for property custodians and house cleaners.

To limit hydrogen peroxide toxicity, use soap and water rather than any disinfectants. When using hydrogen peroxide but also isopropyl or ethyl alcohol, ventilate the room well.

Kids are 79% less likely to spread CoVid to their household members compared with virus-carrying adults.  Australian infectious disease scientists present this conclusion after their study of 213 home transmission clusters living in 12 countries.

Only 3.8% of clusters stemmed from infected children.  The number could be as high as 21% if you only consider clusters with symptomatic kids and those where adults did not travel.

Children are 38% less likely than adults to become infected.  There was no significant difference in CoVid susceptibility between children under 10 and those 10 through 18.

The investigators speculate that infected kids spread CoVid less often since they are less symptomatic and may carry less virus.

Downing cheese and red wine will keep you sharp as you go through life.  Food scientists from Iowa State University report these findings after analyzing data from 12,787 Brits 46 to 77 years of age.

Participants completed Food Frequency Questionnaires and underwent testing of their ability to think on the spot using he Fluid Intelligence test.  Cheese topped the list of “smarts-preserving” foods followed by red wine and lamb but not other red meats.  On the other hand, added salt was counterproductive.

So during the pandemic, arrange virtual happy hours replete with that cheese board and wine carafe.  The food and drink AND the pleasant company will help you fight off those pandemic blues.

CoVid triggers long-term shortness of breath by damaging the diaphragmatic respiratory muscles.  A study from Northwestern in Chicago reports this finding after their in-depth study of 25 long haulers using precise ultrasonic imaging.

While only 12% of these patients had pre-existing pulmonary disease 80% of them had at least one respiratory muscle structural or functional abnormality. Seventy-six percent had reduced diaphragmatic contractility.

Since only 25% of patients had detectable virus in their respiratory muscles, the researchers blame muscle damage on a combination of factors including high dose steroids, general inflammation, and impaired muscle sugar metabolism.

CoVid patients with persisting breathing challenges should have diaphragmatic ultrasounds.

If you must ride in a moving car with a person not in your bubble, which windows should you open? The answer to these questions comes from fluid mechanics researchers at Brown University and UMAss Amherst.

Two occupants should sit diagonally with the passenger in the right rear seat.  Safest is to open all windows to maximize air exchange.  If it’s cold, turn up the heat.  

The two windows you definitely want open are the right front and left rear to create an air curtain.  You’ll get added safety by opening the window next to the person who could possibly be infected: perhaps the Uber driver.

An additional left rear passenger: open all windows.
