Dr. Roger Seaholt, a critical care physician, distills eight pillars of health (NEW START) for longevity and well-being. He emphasizes sunlight's profound impact on mitochondrial function and immunity, alongside the benefits of hot/cold water therapy, fresh air, adequate rest, and faith.
Actionable Insights

1. Prioritize Daily Sunlight Exposure

Aim for 15-20 minutes of direct sunlight daily, ideally in the mornings and evenings, to stimulate mitochondrial function, reduce oxidative stress, and boost overall health, as infrared light penetrates deeply and has benefits beyond Vitamin D production.

2. Optimize Nighttime Darkness

Ensure your sleeping environment is as dark as possible by turning off screens, eliminating nightlights, and using sleep masks if necessary, as light at night disrupts melatonin production and confuses your circadian rhythm, impacting sleep and overall health.

3. Engage in Regular Sauna Use

Utilize saunas regularly, ideally 4-7 times a week, to reduce the risk of cardiovascular disease and potentially boost your innate immune system by inducing an artificial fever response that increases interferon production.

4. Practice Hot and Cold Therapy

Follow hot therapy (like a sauna) with a brief cold exposure (e.g., a minute in a cold shower) to prolong elevated core body temperature and cause demargination, which releases white blood cells into circulation, further enhancing immune response.

5. Spend Time in Green Outdoor Spaces

Seek out natural environments with trees and plants, as they release beneficial phytoncides that can elevate your immune system and promote relaxation; even one day a week outdoors can provide benefits lasting up to seven days.

6. Improve Indoor Air Quality

Ensure good ventilation in indoor spaces by opening windows or doors to reduce carbon dioxide levels, which can negatively impact cognitive performance, and avoid recirculating air in cars for optimal air quality.

7. Supplement Vitamin D with Caution

Consider daily Vitamin D supplementation (e.g., 2,000 IU) to reduce the risk of autoimmune conditions and acute chest syndrome, but get your levels checked periodically as it’s a fat-soluble vitamin and excessive intake can cause issues with calcium metabolism.

8. Cultivate Supportive Faith or Trust

Develop a supportive faith or trust in a higher power and practice unconditional forgiveness, as these are associated with reduced stress, depression, and anxiety, and can enhance the effectiveness of therapeutic interventions.

9. Incorporate Regular Exercise

Engage in consistent physical activity, as exercise offers numerous ‘side benefits’ such as reducing stroke risk, improving mental well-being, and enhancing overall fitness and endurance, without the side effects of medications.

10. Practice Temperance and Avoid Toxins

Avoid harmful toxins such as smoking, excessive alcohol consumption, and amphetamines, as these substances erode organ systems and significantly detract from a long and wholesome life.

11. Use SAD Lamp for Circadian Rhythm

If living at high latitudes or working shift hours, use a 10,000 lux SAD lamp for about 20 minutes in the morning to help set your circadian rhythm and reduce seasonal affective disorder or depression, though it won’t replace the mitochondrial benefits of natural sunlight.

12. Choose Full-Spectrum Indoor Lighting

Opt for incandescent bulbs or full-spectrum lighting where possible, as modern LED and fluorescent lights often provide a narrow spectrum of light lacking beneficial infrared, which can impact visual perception and overall health.

13. Prioritize Whole Food Nutrition

Focus on a balanced and nutritious diet, as the food you consume has a dramatic and fundamental impact on your overall well-being and health.
