High Heat May Kill the Coronavirus

STORY AT-A-GLANCE

  • A recent Chinese investigation suggests COVID-19 is highly sensitive to high temperatures and spreads faster in colder climates; its most rapid spread is occurring at a temperature of 8.72 degrees Celsius (47.7 degrees Fahrenheit)
  • Fever is a core mechanism by which your body fights viral infection. You can simulate a fever by raising your core body temperature in a sauna, steam bath, or by engaging in physical movement to induce sweating
  • A number of studies have investigated the antiviral effects of sauna bathing. For example, a clinical study involving 50 volunteers showed regular sauna bathers had half the rate of common cold compared to nonusers. Those who use a sauna at least two or three times per week also have a lower risk of influenza and pneumonia
  • Sauna use kills bacteria, fungi, parasites and viruses and boosts your immune function by increasing white blood cell, lymphocyte, neutrophil and basophil counts. By elevating your core temperature your body also releases heat shock proteins that help block the replication of influenza viruses
  • Coronaviruses (as a general group) incubate in your sinuses for about three days before moving down into your lungs, and appears to be destroyed by temperatures around 133 degrees F (56 degrees Celsius), which can easily be reached in a sauna

Quercetin and Vitamin D — Allies Against Coronavirus?

STORY AT-A-GLANCE

  • As the outbreak of COVID-19 continues to spread around the world, more than 80 clinical trials are underway testing remedies ranging from intravenous vitamin C and stem cells to HIV drugs and malaria medication
  • A derivative of quercetin has been shown to provide broad-spectrum protection against a wide range of viruses, including SARS. Canadian and Chinese researchers are now collaborating on a study to assess the effectiveness of quercetin against COVID-19 infection
  • Quercetin is a powerful immune booster and broad-spectrum antiviral. It also inhibits the release of pro-inflammatory cytokines, which may be beneficial since serious COVID-19 infection and subsequent death appears to be due to cytokine storm activity
  • While there are no clinical trials investigating vitamin D for coronavirus specifically, there are plenty of data showing it’s an important component in the prevention and treatment of influenza and upper respiratory tract infections
  • Other nutraceuticals thought to be useful in the prevention of coronavirus infection include NAC, spirulina, beta-glucan, glucosamine, selenium, zinc, lipoic acid and sulforaphane
