CBD & COVID-19

CBD & COVID-19

CBD is touted as the "miracle supplement" curing everything from arthritis to cancer. It was only a matter of time before unscrupulous marketers began promoting CBD as a cure for COVID-19. Their rationale for this unsupported claim is that CBD is a strong antioxidant and there is evidence that it can reduce inflammation, a factor which plays a primary role in the severity of COVID-19 infection. The major problem with this irresponsible advertising claim is there is not a shred of evidence that CBD offers any benefit in the treatment of COVID-19. And there is the danger that individuals who develop symptoms of COVID-19 may rely on CBD rather than seeking medical help.


High Stress and COVID-19

High Stress and COVID-19
Previous Performance Tips have focused on factors that impact immune response and immune health. We like to think that our immune response is an independent defense system that seeks out and destroys foreign invaders. That is not the case. Our immune response is significantly affected by health and mood factors such as high stress. Acute stress can help athletes perform better, however, chronic stress plays havoc with our overall health and our immune response. Individuals with elevated, sustained levels of stress have a diminished immune response and are more prone to upper respiratory infections.

Maintaining Immune Health
Last week’s Tip focused on the important role of exercise in maintaining immune system health. The media is communicating nonstop how to minimize exposure to COVID-19 (social distancing, frequent hand washing, listening to health officials). I’ve also been asked if there are products that support immune health. One group of natural products which may offer a benefit are adaptogenic herbs or adaptogens. 

CORONAVIRUS AND EXERCISE

CORONAVIRUS AND EXERCISE
Individuals at most risk for the severe effects of coronavirus have other medical complications or a compromised immune system. We know there is a strong link between hard exercise and our body’s defense system and the link is the stress hormone, cortisol. Cortisol levels, which increase during moderate to high intensity exercise, negatively impact our body’s defense mechanisms. Therefore the logical question is whether exercise increases our susceptibility to the coronavirus. To the contrary, multiple studies show individuals who exercise regularly have a stronger immune system than sedentary individuals. However, the benefits of exercise on your immune response is directly related to...

How To Maintain A Strong Immune System
As we age there is a predictable decline in our immune function. Compromised immunity begins in early adulthood and accelerates rapidly after 40 years of age. Scientist call this Immunosenescence. Immunosenescence explains why older people are at greater risk of infections and diseases. As we age, our immune system does not respond as robustly to allergens and other challenges...

Are You A Weekend Warrior?

Are You A Weekend Warrior?
Intuitively one would expect that individuals who exercise on most days over the course of the week would derive greater health advantages than those who cram their exercise into the weekend, the weekend warriors. A number of studies have suggested that regular exercise over the week delivers more health benefits but these studies involved self-reported activity and are certainly open to error. A recently published study took a more analytical approach to the question of whether regular or concentrated exercise activity is best...
