The Omega-3 Supplementation Guide

While exercise usually supports health, extreme exercise can be detrimental to the immune system in some instances. Studies suggest that people performing moderate endurance exercise experience fewer respiratory illnesses, while athletes performing intense endurance exercise of longer than two hours have an increased risk of illness. Whether extreme endurance exercise suppresses immune function transiently due to stress hormones such as cortisol or via another mechanism is a subject of much debate. In this clip, Dr. Rhonda Patrick describes how varying levels of exercise affect the immune resp...exerciseimmune systemvaccinecovid-19

In 1970, double Nobel Prize laureate Dr. Linus Pauling published Vitamin C and the Common Cold, in which he posited that consuming large amounts of vitamin C could reduce the duration and severity of the common cold. The book effectively put vitamin C on the nutritional map, establishing it as a cure-all in the collective minds of the lay public. Nearly a decade later, Pauling published clinical data suggesting that high dose intravenous administration of vitamin C showed promise as a supportive treatment for cancer as well as a strategy to mitigate the side effects of chemotherapy (https://do...exercisecancervitamin cdepressiondna damageimmune systemoxidative stressautoimmunity

During illness or infection, the body's immune system launches a pro-inflammatory cascade of events that triggers the need for sleep. These events are recapitulated in both exercise and sauna, providing a potential explanation for the sleep-inducing effects of the two activities. In this clip, Dr. Matthew Walker explains how sleep and sauna may induce sleep through their short-term pro-inflammatory effects. ...sleepalzheimer'sinflammationdementiasauna

Genetics plays an important role in longevity, but there is also a strong lifestyle component. Dr. Snyder's research, using deep molecular measurements, indicates that when you exercise, a profound molecular change occurs — particularly when it comes to immune molecules. Exercise induces a variety of beneficial cytokines and other factors that support immune health. In this clip, Dr. Michael Snyder describes how a robust immune system is critical to healthy aging and can be boosted by exercise. ...exerciseaginginflammationimmune system

Exercise is a critical component of public health recommendations to prevent cancer. A growing body of scientific research demonstrates that engaging in exercise after a cancer diagnosis can improve outcomes, but the mechanisms that mediate these effects are not fully characterized. Findings from a new study demonstrate that exercise alters the metabolism of cytotoxic T cells to improve their ability to attack cancer cells. Cytotoxic T cells play key roles in the body's immune response. They destroy malignant cells by triggering apoptosis – a type of cellular self-destruct mechanism that rids...exercisecancerlactate

During exercise, some immune cell numbers in the bloodstream increase dramatically but decrease immediately after exercise and then return to normal several hours later. The reason for this temporary decline in immune cell numbers in the bloodstream is because immune cells travel to other tissues like the lungs because they go there to look for infections. https://www.sciencedaily.com/releases/2018/04/180420122807.htm ...exerciseimmune system

Older endurance cyclists in their 50s to 70s maintained muscle mass, had healthy cholesterol levels, low body fat, and their immune systems looked 30 or more years younger. The study suggests that lack of exercise, and not simply just aging may lead to immune function decline. ...exerciseagingimmune system

Every year, 2 million Americans hear the words "You have cancer." But here's the shocking truth: nearly 40% of those cases could have been prevented, and exercise is one of the most powerful weapons we have against it. While smoking, obesity, and alcohol are well-known risk factors, exercise is often overlooked as a critical tool for both cancer prevention and treatment. Research shows it not only lowers cancer risk but also strengthens the body for treatment, enhances drug effectiveness, and reduces recurrence rates. In this episode, Dr. Kerry Courneya, a leading expert in exercise oncology,...exercisecancer

This is round two of a special Q&A dedicated to COVID-19. The questions in this episode represent what is actually just a small fraction of the many interesting questions submitted from subscribers to my newsletter regarding the on-going COVID-19 pandemic. Hundreds of questions were submitted, ultimately laying the ground work for not just one, but two episodes. Catch the prior episode by clicking here (/episodes/covid-19-episode-1).
