The impact of lifestyle behaviors on a person’s immune system
09/26/2019 // Melissa Smith // Views

A report published in the journal Alternative and Complementary Therapies reviewed how lifestyle behaviors can influence the immune system of an individual. This report was authored by Jane Hart, a researcher at Case Western Reserve University School of Medicine.

  • When preparing for cold and flu season, conventional training does not teach clinicians about lifestyle behaviors.
  • Instead, the discussion typically moves toward hand hygiene and avoiding crowded places and people who are sick.
  • While these are important information, one of the most important doctor-patient discussions for preventing infection is to discuss lifestyle choices, especially when a patient is following a sedentary lifestyle and unhealthy diet and living a stressful life.
  • There are known risk factors related to lifestyle for colds and other viruses, flu, and pneumonia.
  • These include smoking, excessive alcohol intake, obesity, a weakened immune system, chronic disease, lack of sleep, and chronic stress.
  • On the contrary, people who engage in healthy lifestyle behaviors are less prone to both infections and chronic disease.
  • Lifestyle behaviors that contribute to a healthy immune system include regular exercise, healthy diet, seven or more hours of sleep, avoidance of smoking, limiting alcohol intake, and learning stress management techniques.
  • Many clinicians also observed that people who practice healthier lifestyle behaviors are sick less often than those who have poor lifestyle behaviors.

Overall, the report suggested that having a discussion and providing specific direction about healthy lifestyle choices is an effective way to prevent respiratory illness.
