Immunologist Reveals Science-Backed Ways to Strengthen Your Immune System
Strengthening the immune system remains a key concern for many, especially as cold and flu season approaches. A new book by immunologist Dr. Marianne Davies, published in 2020, outlines practical ways to support immune health—from diet and exercise to emerging trends like ice bathing and music therapy.
Dr. Davies recommends a Mediterranean diet rich in micronutrients and omega-3 fatty acids as a foundation for immunity. She also advises regular outdoor exercise, sufficient sleep, minimal alcohol, and stress reduction. These lifestyle changes, she argues, provide a more reliable defence than quick fixes.
While no single method guarantees immunity, Dr. Davies’ book offers a mix of well-supported and experimental strategies. Readers are encouraged to share their own home remedies in the comments. The most reliable advice still centres on balanced nutrition, rest, and stress management—habits that benefit overall health beyond just the immune system.
