Another Year of Wearing Masks?

/in /by

“What do you think? Will we be wearing masks another year?” That’s the question that someone asked me at the health club. I shrugged and said “Maybe. But you know in reality, it isn’t all that bad. My grandson’s kindergarten class wears masks all day, and they seem to manage just fine.” He agreed it wasn’t a problem.

He then went on: “I think it makes you pay more attention. One thing I’ve noticed is that there doesn’t seem to be as much flu this year so far.”

He went on to say, “You know, I clean the machines before I work out and again after I work out. In the past, we were supposed to clean them when we were done, which I did. But I’m just taking the extra step like they ask and clean it before I use it. I bet that makes a difference.” I told him I agree.

I’ve thought about it for a couple of days, but I’m not clairvoyant so I have no idea how much longer we’ll be wearing masks. I don’t think it would be all that bad if we got into the habit of using masks in public, social distancing a little, washing our hands, and cleaning public surfaces before touching them. We would reduce the risk of catching all infectious diseases. The following years’ flu seasons would be easier, and you can’t spread it if you don’t get it.

Just like the guy in the health club said, I think changing our habits would really make a difference. If we did, we just might find that stay-at-home mandates are a thing of the past. How great would that be?

Ideas for Long-Hauler Recovery from COVID-19

/in /by

There is currently no research on ways to recover faster if you have chronic symptoms after your initial COVID-19 infection. When this occurs, the best thing we can do is to use what we know to help restore the body as long as it does no harm. That’s the approach I used when putting this together.

Understand these recommendations are hypothetical, but they’re based on what we currently know. Much of it depends on the types of symptoms that you may have; deep muscle pain is not the same as a chronic cough or the loss of smell.

  • Try to get some exercise, preferably outdoors. Even brief stretching exercises, including deep breathing, are better than nothing. As you gain back strength and lung capacity, you can increase the amount and types of exercise, but it’s important to get blood flowing to the extent that you can.
  • Increase your intake of vegetables and fruits and decrease your intake of refined carbohydrates and saturated fats, especially from deep fried foods. Give your body the best nutrition that you can afford—it doesn’t have to be all organic. Raw fruits and vegetables are better because of the phytonutrients and the potential for beneficial bacteria.
  • Take these supplements that may help, depending on your symptoms. Use vitamin D for immune support; probiotics for the microbiome and immune support; high-DHA fish oil for any neurological issues including the loss of smell and taste; coenzyme Q10 for muscle fatigue and soreness; and a multivitamin-multimineral that contains plant concentrates. I know that there are a whole lot more antioxidants and herbs that you may hear about, but all of these have known functions they can benefit the organs involved.

That’s it. It sounds like the recommendations I always give: Eat less. Eat better. Move more. Well, there’s a reason for that; they really help you get healthy. The supplements target those body systems and organs to help their recovery as well.

One more thing: because the mental aspect of being a long-hauler is so tough, make an extra effort to do the things that make you happy but don’t take too much energy: video chat with your favorite people, wear your favorite or most comfortable clothes, listen to your favorite music, or get some sunshine even if it’s just putting on a coat and sitting outside for a few minutes. If prayer and meditation help you, be sure you make time for those.

Until the science and research catches up with the long-haul COVID-19 symptoms, this is the best approach I can recommend. This plan may work or it may not. But one thing is for sure: you’ll be getting better nutrition as a result.

The COVID-19 Long-Haulers

/in /by

I’ve spent most of my time on COVID-19 talking about how to prevent getting the infection, but I haven’t talked about what happens if you get the infection and recover from it. I hope you have a mild case, and in a week or two, you’re back in business. Your body has built up antibodies, so research shows you should be in good shape at least for a while.

However, some people are experiencing symptoms long after they’ve recovered from the initial infection. They call themselves long-haulers. The path of the disease is unpredictable; people feel better and think they’re on the mend and then get walloped by the symptoms again. The top five symptoms are fatigue, shortness of breath, joint pain, chest pain, and cough. For some people, the after-effects of having COVID-19 are actually worse than the initial infection. Fatigue and shortness of breath seemed to occur in over half the people who’ve had confirmed COVID-19 infections, and they last for several months.

Paula and I, and actually the entire family here at home, probably had the virus. This happened way back in January and early February, before we were really aware the virus existed. Paula had other complicating factors and still has unexplained fatigue. What can we do about it? There’s no research to guide us, but I’ll give it my best effort in Saturday’s Memo.

Why We Need Hope

/in /by

I hope you all had a good Thanksgiving and were as safe as possible. The COVID-19 seven-day average continues to stay over 150,000 cases per day. We’ll find out in a couple weeks how we did during the Thanksgiving holiday related to masking and social distancing. It’s difficult to be without family and friends, especially over the holidays, but the one thing we can take solace in is that this is temporary; the better we all follow the rules, the sooner we can all be together again.

It reminds me of an interview a well-known business advisor had with a prisoner of war in Viet Nam years after the war ended. He asked who did better in captivity—people who were optimistic about rescue or those who decided they would simply endure? The answer surprised him: the optimists did far worse than other POWs. The optimists would say, “We’ll be out by Christmas for sure!” Then Christmas would come and go, so they would pick the next significant event and say the same thing. The events would pass, one after another, and soon, the optimists lost all hope.

Don’t do that. One thing we have is hope. The current treatments for those who get COVID are better than six months ago, and they will be better tomorrow as we learn more about the disease. Vaccinations will start soon and while the distribution will take time, there’s hope for those who are most at risk. If we do all we can with the things we can control, there will be an end to this. We don’t know exactly when that will be, but it will happen. Until then we grind it out, we endure. We’re tougher than we think we are. Let’s prove it.

Another Path to Trained Innate Immunity

/in /by

There is one more action that may give a person a way to enhance trained innate immunity short of catching COVID-19 itself, and that’s to catch a cold. Specifically, a coronavirus cold. I read a great article in the New Scientist that I’ll summarize for you. I urge those of you who want to know more to read the paper listed below.

There are four fairly common coronavirus colds we all get at some time: OC43, HKU1, 229E, and NL63. In a study cited by the article in the New Scientist, researchers collected data from medical records of just under 16,000 patients. Of those, 875 had a documented case of coronavirus colds verified by a test; the rest of the subjects did not. Those who had a confirmed case of one of the types of coronavirus colds had milder cases of COVID-19, fewer required intensive care, and fewer had to be put on mechanical ventilation. The mortality rate was 4.8% in those who had a prior cold and 17.7% without a verified cold test.

The upside is that it seems to provide some trained immunity against COVID-19. The downside is that the immunity seems to wane over the years. I think this research is important because it shows one more way to train the immune system. It may not be practical in the real world, but if you happened to catch a simple cold in the past six months, you may have some innate immunity—if you happened to catch the correct form of the cold virus. For the rest of us, the flu shot is still the best course of action in training our immune system.

How to Train Your Immune System

/in /by

Here’s where we stand: healthcare workers in the Netherlands who got last year’s flu vaccine had fewer cases of COVID-19 than their unvaccinated counterparts. In addition, white blood cells treated with the flu vaccine, with or without the tuberculosis vaccine, demonstrated enhanced immune responses when exposed to the COVID-19 virus.

Where does this lead? It’s a quality known as trained innate immunity: exposure to one vaccine, such as the flu vaccine, will train the immune system to respond to another virus such as COVID-19. However one test-tube study does not prove it will work in the real world. Let’s look at some additional research.

The Flu Vaccine and COVID-19

Several retrospective studies have looked at the flu vaccine and COVID-19. In two studies from Italy, people over 65 who got the flu vaccination had a lower mortality rate from COVID-19. There are several more observational studies, but these studies don’t prove cause and effect.

There are problems doing clinical trials, ethical considerations being one of them; for example, if getting the flu vaccine proves to have a beneficial effect, it puts the people in the study who did not get the flu vaccination at risk. There’s also the possibility that it might have been other factors that were actually beneficial, such as lifestyle. It’s all very complicated.

Other Vaccines and COVID-19

Several studies have reported an enhanced immune response against COVID -19 after certain vaccinations. The polio- and measles-containing vaccines have been identified as stimulating the immune system and providing protection against covid-19. The bacillus Calmette-Guérin (BCG) vaccine against tuberculosis could protect against COVID-19 as well. Both have been investigated as potentially being immune-stimulating against severe upper respiratory infections. In countries where BCG is given on a regular basis, the rates of COVID-19 have remained lower than in countries that no longer use it because tuberculosis has been eradicated for the most part.

The Bottom Line

These are observational studies; there’s a lot of research to be done to find out how vaccinations for one virus can provide benefits against a completely unrelated virus. Trained immunity means immune cells are reprogrammed in some way. The “how” is important because what we may find out is that there’s another way to do it, or research may find other factors such as vitamin D status that complement the vaccinations to enhance trained immunity.

One lesson this foray into trained innate immunity has taught me is that our immune system gets weaker as we get older and must constantly be “trained.” It’s not just diet, exercise, and supplements that help our innate immunity; it seems that exposure to other viruses in the form of vaccines may help protect us against severe cases of COVID-19 and possibly other viruses as well. Right now the simplest way to do that is to get the current flu vaccination. We may not evade catching COVID-19, but having a better-trained immune system may help us avoid the most severe symptoms and possibly even death.

I got my flu vaccination and so did Paula. Talk with your physician and see if it’s right for you. Your body. Your choice. But I hope you’ll do whatever you can to put the odds in your favor.

How Vaccines Can Affect COVID-19

/in /by

In vitro studies, more commonly called test-tube studies, are used when you want to see if there’s a relationship between cells and microorganisms. In the case of the researchers in the Netherlands, blood cells, vaccines, and the COVID-19 virus were used. While the laboratory techniques were complex, here’s what they found.

The researchers isolated peripheral blood mononuclear cells from the Buffy coat layer of cells. The Buffy contains primarily white blood cells after centrifugation. The researchers then exposed the white blood cells to the flu vaccine commonly used in the Netherlands for 24-hours. Half the samples were also exposed to the bacille Calmette-Guérin vaccine, typically used for tuberculosis. After a week, the samples were exposed to the COVID-19 virus. The objective was to see if immune system markers were increased after exposure to the virus.

The flu vaccine increased the immune capability of the white blood cells. The addition of the BCG vaccine increased the capability of the immune response. The cells were better able to make cytokines faster. If it happened in humans, the cytokines would be able to respond faster thus reducing the ability of the COVID-19 virus to replicate.

What does this all mean? I’ll finish this on Saturday.

The Flu Shot and COVID-19

/in /by

This week, I’m going to review a series of studies that outline a strategy that includes getting the current flu vaccination. The first study is an observational study. In my opinion, it’s the way research should begin: look for relationships between factors first, and then conduct experimental trials.

Researchers in the Netherlands used the medical records database of a large hospital to find out the answers to a couple of questions. First, of over 10,000 healthcare workers who worked there, they wanted to find out how many got the flu vaccination during the 2019–2020 flu season last fall. Then they examined how many employees got the COVID-19 infection since the pandemic began. They learned that of those who were not vaccinated, 2.23% got the COVID-19 virus; of those who got the flu vaccination, 1.33% got COVID-19. That works out to a 39% reduction in the risk of catching COVID-19 for people working in a healthcare setting if they get vaccinated for the flu.

As we know, there’s not a cause-and-effect relationship in these types of studies. But it does indicate that it’s a place to look—which is exactly what they did in the next phase of the research paper. More on Thursday.

Taking Charge of Your Health

/in /by

Flowers and trees have been winterized. The mulch has been spread throughout the yard. The leaves remain a continuing problem, but in short order the snow may take care of that. The one thing that I like about working in the yard is it gives me an extended opportunity to think. There are two things they have been on my mind.

Body Composition and Aging

I completely underestimated the change in body composition that occurs as we get older. I weigh about seven pounds more than I did about a year ago; the problem is that it’s all settled right around my waist. I’ve lost muscle mass in my arms, shoulders, and even my legs. From a strictly physical perspective, that’s the challenge I intend to address next. This will not be a “by the end of the year” thing because it’s going to take some time. I’ll write about how I intend to do it and then keep you posted on how it goes. Everyone is welcome to join me.

COVID-19 Isn’t Going Away

The second thing I’ve been thinking about is the COVID-19 virus. I’ve had the opportunity to read a lot of material I want to cover in upcoming memos that are not related to the pandemic. But the damage from this pandemic continues to increase, at least for the time being, and it would not be responsible for me to ignore COVID-19 all together. There’s some fascinating research that I think adds to the Swiss cheese approach in the last Memo.

Many people seem to be working themselves into a frenzy over possible state restrictions on activities and the insistence on wearing masks. Many of you know that attitude is everything. If we, as a nation, could just make up our minds that we’re going to do the best we can in each and every state, we could get through these temporary restrictions and get back to living our lives more completely than we are able to right now. If we don’t, then this is going to continue until we all decide to take things seriously.

The Bottom Line

Every morning, when I take Riley to school, we review our rules. The first rule is “Do the best you can.” It doesn’t have to be perfect. And you will make mistakes. Just do the best you can each and every day, because that’s all you can do. We review it after school on the drive home, and he gives me a thumbs up if he did his best that day. I hope we all can do the same thing in dealing with our health. The bottom line is that in all phases of our health, let’s do the best we can.

The Insider Conference Call is Wednesday evening. Do you have questions you’d like answered about supplements, weight loss, or any other topic related to health? Become an Insider today and gain the benefit of our discussion.

Swiss Cheese COVID Protection

/in /by

You’re probably thinking “First, zeptoseconds, then speeches and dancing, and now Swiss cheese? How are they related?” I’ve used the concept of discrete time intervals to make a point. Each discrete time interval of seemingly separate tasks can be put together to make up something that can be greater than each individual part—in this case, a way to control the spread of the COVID-19 virus.

The Swiss cheese concept is credited to Dr. James Reason who applied it to safety in many industries, but it fits here very well. For example, wearing a seat belt every time you drive reduces the risk of serious injury. But a specific type of collision, say hitting another vehicle from behind that doesn’t have operational brake lights, could still cause serious whiplash. In a time interval too fast for human response, a sensor sends a signal to deploy an airbag to limit injury, and there are now sensors that will automatically brake to stop the car. Different actions performed in discrete time intervals put together can make driving safer.

The Swiss cheese idea is that while there are holes in any single slice, the holes don’t extend the entire brick of cheese; any single hole will eventually get blocked. If you have enough safeguards, the combination of imperfect strategies will work together to lower your risk. I’m adding time to it to illustrate how little time it can take.

Four Steps to Keep Yourself Healthy

1. Wear a mask all the time when in public. Using my five-year-old grandson Riley as an example, it takes no more than 10 seconds to put on a mask. (He and his classmates wear masks all day in kindergarten, so don’t tell me it’s too hard to do; here’s more on masks.)

2. Social distance and spend no more than 15 minutes in any single encounter (four hours in a poorly ventilated space with strangers is just asking for trouble). A shorter time is better.

3. Clean and sanitize surfaces regularly. This may take up to 10 seconds for the surfaces we encounter frequently.

4. Wash your hands often with soap and water; sing the ABC song to make sure you scrub long enough. Or use a hand sanitizer with 70%+ alcohol, and the virus is destroyed within 30 seconds.

Any single strategy has holes, but used together, we can keep the risk for ourselves and others very low.

The Bottom Line

My point this week is to demonstrate that you have enough time to reduce the COVID risk for yourself and others. Small discrete acts can add up to a powerful strategy; doing enough of them helps put the odds in your favor. As I said before, there’s nothing to fear. Just respect the virus and act accordingly.

If you’re a U.S. citizen, make sure you vote next week. With everyone glued to the election results, including many readers in other countries, I’m sure your attention will be elsewhere so Paula and I are taking next week off. The leaves and the mulch await, and I’ll work on getting prepared for some great new ideas for the New Year.
