Mindsip insights from this episode:
Use ice packs to protect fertility during sauna sessions
To counteract potential heat damage to fertility during intense sauna use, you can use ice packs on the testicles to keep them cool.
Utilize sauna sessions to mimic zone 2 workouts
A sauna session is considered an 'exercise mimic' because it increases heart rate to a Zone 1 or Zone 2 level and works out your blood vessels by increasing nitric oxide production.
Enhance vascular health with seven days of sauna sessions
After only seven daily 200°F sauna sessions, central systolic blood pressure improved by nearly 6% and a measure of aortic flexibility increased by 21%.
Reconsider aggressive sauna use to improve sleep quality
Contrary to the common belief that it aids sleep, an aggressive daily sauna protocol can initially disrupt sleep by elevating the sympathetic nervous system.
Choose traditional dry saunas for optimal health benefits
The most robust clinical research supports traditional hot, dry saunas (180-212°F), not infrared saunas which typically only reach a less effective temperature of 140-150°F.
Measure sweat to personalize electrolyte replacement
You can use a Gatorade sweat patch to measure your personal sweat rate and sodium loss, allowing for precise electrolyte replacement to prevent severe cramps.
Avoid cotton and tap water in saunas to prevent toxin exposure
Avoid wearing cotton clothing that may contain glyphosate and never pour tap water on sauna rocks, as the heat can release these and other chemicals like PFAs.
Shower immediately after sauna to eliminate toxins
You should shower immediately after a sauna session to wash off excreted toxins like heavy metals and PFAs to prevent them from being reabsorbed into the skin.
