Once a week isn't a dose.” ## Start today 1. Put 4 sauna sessions in this week's calendar and a glass of water beside each one. ## Why it works Raising core temperature by a degree or two is a controlled heat stress. The body answers it the way it answers moderate aerobic exercise: heart rate climbs, vessels widen, plasma volume grows, and heat-shock proteins are made. Loading the heart and vessels without loading the body mechanically is how it works. It is what sits behind its link with heart outcomes in studies that tracked people. The tested protocols are specific. The heart-failure trials used infrared sauna at 60 degC for 15 minutes, followed by 30 minutes of warm rest, five times a week for 2-4 weeks. The heat-therapy blood-pressure review pooled 30-90 minute exposures over 10-36 sessions. In the Finnish long-term study, the link tracked dose. It appeared at 4-7 sessions per week and sessions longer than 19 minutes, not at 1 session per week. New Heroes The full library. Elon answers every weekday.

I'm certainly happy as a sauna user. But there's no de-toxification in this.” > > Hacker News thread on a wearable study of sauna and heart rate (448 points, 236 comments) - > “I’m not surprised that it failed to demonstrate longevity benefits. Let’s face it, if it did, it’d be highly likely that the Finns would overpopulate the ranks of Supercentenarians.” > > Rapamycin Longevity forum thread on a sauna trial in heart patients (96 posts, 9,677 views), reply with 5 likes - > “But since I started doing sauna regularly (once a week) I started to get sick less. I’m talking colds or flues.” > > Hacker News thread on a Finnish sauna immune-response study (386 points, 284 comments) ## The studies Every study behind this page. - [Acute and short-term efficacy of sauna treatment on cardiovascular function: A meta-analysisPubMed, PMID 32814462](https://pubmed.ncbi.nlm.nih.gov/32814462/?ref=elonmuscular.com) - [The effect of heat therapy on blood pressure and peripheral vascular function: A systematic review and meta-analysisPubMed, PMID 33866630](https://pubmed.ncbi.nlm.nih.gov/33866630/?ref=elonmuscular.com) - [Effects of sauna bath on heart failure: A systematic review and meta-analysisPubMed, PMID 30239008](https://pubmed.ncbi.nlm.nih.gov/30239008/?ref=elonmuscular.com) - [Hot spring and sauna use for improving blood lipid profiles: A systematic review and expert consensus on efficacy and recommendationsPubMed, PMID 40914321](https://pubmed.ncbi.nlm.nih.gov/40914321/?ref=elonmuscular.com) - [Arsenic, cadmium, lead, and mercury in sweat: a systematic reviewPubMed, PMID 22505948](https://pubmed.ncbi.nlm.nih.gov/22505948/?ref=elonmuscular.com) - [Registered trial NCT06875466Trial registry](https://clinicaltrials.gov/study/NCT06875466?ref=elonmuscular.com) - [Registered trial NCT07520929Trial registry](https://clinicaltrials.gov/study/NCT07520929?ref=elonmuscular.com) - [Registered trial NCT07158047Trial registry](https://clinicaltrials.gov/study/NCT07158047?ref=elonmuscular.com) - [Registered trial NCT07468344Trial registry](https://clinicaltrials.gov/study/NCT07468344?ref=elonmuscular.com) - [Registered trial NCT05931497Trial registry](https://clinicaltrials.gov/study/NCT05931497?ref=elonmuscular.com) - [Laukkanen et al., 2015PubMed, PMID 25705824](https://pubmed.ncbi.nlm.nih.gov/25705824/?ref=elonmuscular.com) - [Laukkanen et al., 2017PubMed, PMID 27932366](https://pubmed.ncbi.nlm.nih.gov/27932366/?ref=elonmuscular.com) ## Words on this page PMID A study's ID number in PubMed, the public index of medical research.
