The differential effects of exercise intensity and duration on immune function | Rhonda Patrick

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 response in different ways.

Thank you for the video. So if you over do it, you leave yourself at risk. Most people are not exercising at the elite level, but during these times, moderate exercise - being careful not to overtrain and getting plenty of sleep is probably a good idea.

Overtraining i.e. too much exercise can lead to developing the Parasympathetic or Sympathetic Overtraining Syndrome, which can increase upper respiratory tract infections.
