| Does a long hot bath do the same? |

| If you are a man, the hot water has a deleterious effect on your testicles' ability to make sperm. But so do saunas apparently. https://pubmed.ncbi.nlm.nih.gov/23411620/ That one was 80-90C, which is a really hot sauna. |

| ▲ | orthoxerox 6 hours ago | parent | next [-] | | Finns go to sauna at least once every week and haven't gone extinct yet. | | |
| ▲ | nnevod 6 hours ago | parent [-] | | Still there are studies that regular sauna does decrease testosterone production. It's not hard to counter though, ice packs applied to testicles ( not direct ice, ice in a cloth) during sauna are effective for that purpose. And maybe Finns don't go to sauna when they plan to conceive? Does Finland have a lower rate of unwanted pregnancies? | | |
| ▲ | 2000UltraDeluxe 4 hours ago | parent [-] | | Finland's fertility rate drove off a cliff in the 60's like in so many other countries. If sauna has an overall effect we wouldn't know as we've nothing to compare with -- going to sauna is rather universal and the tradition is ancient. |

| Yes, if by hot bath you mean submerging yourself to neck level in 40ºC or above water for 20-30 minutes. There's no reason to believe any "heat therapy" modality is superior to another as long as you suffer equal heat stress. For the record, if you're not acclimated, intense heat exposure is a lot more agonising than 30 minutes of exercise for less benefit. If you haven't experienced a properly tuned sauna in your life you are in for a ride. What's being studied in the literature is nothing like your standard hotel experience. |

| ▲ | amarant 2 hours ago | parent | next [-] | | The standard hotel experience is sitting wrapped in a towel and longing for my winter coat! Actually I would probably feel similarly in this study, 73°c is really cold for sauna. 90°c-100°c is the sweet spot | |
| ▲ | lxgr 6 hours ago | parent | prev [-] | | How are you suffering equal heat stress from being submerged in moderately warm water and breathing very hot air? I could imagine quite different effects on airways and skin, for example. "Exactly the same effect" seems like the unexpected outcome here. > intense heat exposure is a lot more agonising than 30 minutes of exercise for less benefit Having to do absolutely nothing other than not leaving is quite different from pushing through a physical activity that can also easily be causing all kinds of discomfort. | | |
| ▲ | r0me1 5 hours ago | parent | next [-] | | It's all about raising your core temperature, water transfers heat to the body much more efficiently than air, so water at 104F ends up raising your body core temperature as much as a dry sauna at 170F. I did some experimentation on this, I have access to a dry sauna at my gym and I track my HR and exertion levels, I did the same with the hot tub at home making sure the water temperature doesn't go below 104F and im fully submerged to the neck, 30 mins session in both cases. The graphs look pretty much identical, same HR uptrends. So as far as cardio effects and heat shock proteins I do believe they are the same, not sure if there could be any benefit to breathing dry hot air for the lungs, but so far most benefits from sauna come from raising core temp | | |
| ▲ | pstuart 4 hours ago | parent [-] | | Too lazy to find it, but Dr Rhonda Patrick (a longtime advocate for saunas for their health benefits) reported that hot tubs can provide the same results as saunas -- and they are much more pleasant to use. | | |
| ▲ | zemvpferreira 3 hours ago | parent | next [-] | | Not to beat my own dead horse but at the heat stress needed to cause an adaptation there’s nothing pleasant about the experience. If it’s not causing nausea and palpitations, it’s not hot enough. | |

| ▲ | zemvpferreira 6 hours ago | parent | prev [-] | | Have you tried submerging yourself in moderately hot water, I wonder? And have you spent some time pondering the difference in heat transfer between convection and conduction? |

| It might not do the exact same, but it will have some effect. A lot of the benefit comes from the raised heart rate and opening of the blood vessels that the sauna produces, and I can expect that a warm bath would also have a similar effect. I think both are also known to reduce stress, which can help to lower blood pressure. |

| Almost certainly but most people don’t find it as enjoyable. Also the problem of keeping the bath hot enough for 20-30 mins. |
