Sauna DEMOLISHES male fertility @kbassphiladelphia

Uploaded May 2022 | Updated September 2026, 23 hours ago

In this podcast, I discuss a paper that shows profound reductions in sperm concentration (nearly 75%), total sperm count (2/3), and sperm motility (half) after just two 15-minute sauna sessions per week for three months (PMID 23411620). These changes were not reversed after three months cessation of sauna use; a full six months were required for these changes to reverse. It is unknown how the sauna may impact spermatogenesis among those who already have impaired testicular function or during development.

It is important to fully explain the risks and harms of interventions that are massively hyped on social media. This podcast offers itself as a corrective to overhyping by the most popular and well-known American health influencers.

$The importance of protein in maintaining long-term health (and how almost nobody gets enough) This episode is for the vegans who say that plant-based diets provide enough protein. Not only do they provide less protein than omnivorous diets. But in old age, even omnivorous diets could benefit from a much higher protein intake. I discuss a large randomized controlled trial published in the British Medical Journal that clearly shows otherwise. Vegans would have you believe that there are no benefits whatsoever to consuming animal products. And believe me, I sympathize with the vegans. I have eaten very little meat for the past 15 years. For 3, I was a vegan. And for the past several years, I have been a pescatarian. So I want for it to be true that eating animal products is not healthy for anyone. That would be awfully convenient because it would make the story of health and my personal belief system line up perfectly! Unfortunately, that is not how reality works. And if we want to make the best decisions, we have to acknowledge REALITY. In a new randomized controlled trial, 7195 nursing home residents (average age 86 years old) were randomized to receive supplemental yogurt, milk, and cheese, or their usual menu. What happened? Daily intake of calcium doubled. Protein intake increased by 20%. And those receiving supplemental dairy reduced their rate of: 1. Hip fracture by HALF; 2. All bone fractures by a THIRD; and 3. Falls by 11%. This effect may have been mediated in part by favorable differences in bone characteristics in the group receiving supplemental dairy versus the control group. The bones of the group receiving supplements were much denser at the end of the study. Likewise, the group receiving protein supplements saw a slight increase in muscle mass, while the control group lost almost 2 kilograms, or 5 pounds, of muscle. And this was from a protein intake supplemented on top of an intake already in excess of the intake recommended by official government dietary guidelines! This may have impacted the risk of falling. And impressively, the impact of the intervention was seen within 6 months! It is possible that plant protein with calcium rather than dairy protein could have achieved the same effects. But what is for sure is that supplemental dairy has been shown to play an important role in preventing debilitating bone fractures in the elderly. Vegans, pay attention! It is better to accept these findings and try to build something out of them than to wave your hands and try to deny them.
