Q&A 417: Dry Vs Infrared Saunas, The Best Blood Tests For Biohackers, Early Cancer Detection, How To Fix Brain Fog & Much More | Ben Greenfield Fitness

Key Takeaways

  • A newly created blood test is able to detect cancer four years prior to the onset of any symptoms
  • Order of priorities for biohacker testing: self-quantification device, comprehensive blood panel, genetic testing, and stool testing
  • Brain fog is usually the result of inflammation of the nervous system which ultimately affects the limbic system
  • There are benefits to both dry and infrared saunas but infrared saunas allow you to mix modalities for a range of benefits

Introduction

Been Greenfield answers listener questions about sauna, blood testing for biohackers, the latest in cancer research, and how to manage brain fog.

Latest in Cancer Research

Blood Panels for Early Cancer Screening

  • Recommended book: Metabolic Approach to Cancer by Nasha Winters
  • Blood panels for monitoring and early detection: sedimentation rate, ESR, HSCRP, LDH, insulin, insulin-like growth factor, hemoglobin A1C, vitamin D
  • Lactate dehydrogenase (LDH), a composite of different enzymes in the body has been increasingly touted as a standard cancer biomarker

What Are The Best Biohacker Tests?

  • Daily self-quantification: heart rate variability (HRV), daily step count (shoot for more than 10,000 steps), sleep cycle tracking – all can be measured with whoop or oura ring
  • Genetic testing: use a website like StrateGene and identify “dirty” genes that may be affecting energy and sleep levels
  • GI testing: use GI Effects Comprehensive Profile to learn about maldigestion, inflammation, metabolite imbalances, infection, etc.
  • Comprehensive blood panel: use a company like Wellness FX to test mercury, iron, thyroid uptake, hormones, blood count, metabolic panel, etc.
  • NutrEval allows you to dig in deeper to omegas, amino acid profile, selenium, copper, zinc, and other micronutrients that don’t appear on a basic blood panel
  • Deeper hormone testing: DUTCH test takes deep dive into hormones via urinary tests
  • Later tests: full microbiome panel, longevity tests (such as telomere length)
  • Order of priorities: self-quantification device, comprehensive blood panel, StrateGene, GI Effects Comprehensive Profile – then if you have money left, add NutrEval panel and DUTCH test – icing on the cake is the full microbiome analysis and telomere testing

How to Clear Brain Fog

  • Symptoms of brain fog: confusion, inability to sustain focus, inability to memorize or concentrate, low energy
  • Hidden causes of brain fog: inflammation of the nervous system that affects the limbic system, which is the control center for mood, appetite, emotions, etc.
  • Lectins and/or oxalates are major triggers for inflammation
  • Recommended books for diet information and sensitivity: The Plant Paradox by Steven Gundry and Grain Brain by David Perlmutter
  • How to treat: fix inflammation and explore genetic testing and biohacker testing and heavy metal testing if it’s unresolved through diet and lifestyle
  • Wellue O2 ring can measure oxygen saturation while sleeping and throughout the day which can be related to sleep apnea and useful in unresolved brain fog
  • Identify the source of brain fog before loading up supplements
  • Action plan: measure sleep, manage stress and anxiety, avoid sugar, avoid alcohol

Traditional Versus Infrared Saunas

  • With infrared saunas, you miss out on the benefits of a steam component you get with Finnish/traditional/dry saunas
  • Ben Greenfield uses an infrared sauna but has thought about adding dry barrel sauna
  • The temperature for traditional saunas will get much hotter than infrared saunas
  • You can add a fan to an infrared sauna to continuously push the heat down
  • Skin warming creams like Prototype 8 can also make up for lower temperatures
  • Most studies that have been done on heart health and health benefits have been done in traditional saunas
  • Non-sauna option: Higher Dose heat blanket
  • Ben Greenfield personally recommends infrared saunas because you can stack modalities for additional benefit

Physiological Responses to Maximum Eating in Men

  • A study looked at metabolic consequences when you eat too much  
  • Participants consumed almost twice as much pizza as they would
  • Average calorie intake was 3,000-4,000 calories for one meal
  • Blood glucose was no higher than participants who consumed regular portion
  • Insulin and blood lipids were only slightly higher
  • Hormones indicating satiety skyrocketed
  • Limitation: study didn’t look at inflammation and related markers
