How to elevate the immune system?

To elevate the immune system, Dr. Rhonda Patrick emphasizes several strategies focused on nutrition, exercise, and lifestyle factors:

1. Dietary Fiber: Consuming dietary fiber is crucial as it feeds gut bacteria, which produce short-chain fatty acids. These fatty acids help regulate the immune system by increasing T regulatory cells that attenuate inflammation. Lack of fiber can lead to a hyperinflammatory state, contributing to various diseases 1 2.

2. Zinc: Supplementing with zinc, especially in the form of zinc acetate or gluconate lozenges, can reduce the duration of common colds by about 33%. Zinc plays a significant role in immune function and inhibits viral replication 3.

3. Omega-3 Fatty Acids: EPA and DHA from omega-3s are critical in resolving inflammation post-infection. They convert into specialized pro-resolving mediators that support healing, particularly in the respiratory tract 3.

4. Exercise: Regular moderate exercise (about one hour, five days a week) can boost immune function. However, very intense or prolonged exercise can suppress the immune system, making one more susceptible to illness. Exercise helps by increasing immune cell activity and their relocation to tissues, thus enhancing immune surveillance 4 5.

5. Sauna Use and Heat Stress: Engaging in sauna use can stimulate the immune system, particularly enhancing lung function and reducing respiratory tract infections. Heat stress from saunas can boost the innate immune system, potentially mitigating viral infections like COVID-19 6.

6. Vitamin C: While general vitamin C supplementation might not markedly improve immune function in all individuals, those engaged in high-endurance exercises might see benefits when combined with other antioxidants such as vitamin E and β-carotene. This can enhance neutrophil function and protect against exercise-induced oxidative damage 2.

In summary, a combination of a fiber-rich diet, proper micronutrient intake (like zinc and omega-3s), moderate exercise, and lifestyle practices like sauna use can significantly enhance immune function.
