8 Pillars for Building Your Immune System | Dr. Roger Seheult & Dr. Andrew Huberman

NEWSTART: A Framework for Health and Immune Support

Dr. Roger Seheult describes NEWSTART as a practical framework for supporting general health and immune function. The mnemonic is credited to physician Dr. Neil Nedley.

• Nutrition: Favor natural foods and limit processed foods.
• Exercise: Aim for mild-to-moderate activity. Seheult describes a “J-hook” relationship: moving from no exercise to some activity may reduce inflammation, while very high levels of exertion may require extra care.
• Water: Consider hydration and external water practices, such as saunas or cold plunges. Seheult notes that these are areas of ongoing discussion and research.
• Sunlight: Spend time outdoors and get sunlight.
• Temperance: Avoid toxins and other substances or exposures that can harm health.
• Air: Seek fresh air and spend time in nature. Seheult mentions research on tree-released compounds called phytoncides, as well as practices such as forest bathing.
• Rest: Maintain good sleep habits. Seheult points to research supporting roughly 7–8 hours of sleep for immune health.
• Trust: Reduce stress through faith or trust in a higher power, as well as supportive relationships and community.
