Deliberate heat exposure may extend life by activating the FOXO3 genetic program, which is involved in DNA repair and clearing senescent cells.

“Sauna exposure, in particular sauna exposure two to three times or ideally four to seven times per week in that 80 to 100 degree Celsius range has been shown to upregulate levels of FOXO3.”

“For the rest of us, at least to my knowledge, I don't have one of these health-promoting FOXO3 mutations. Remember, mutations can be beneficial or they can be detrimental. This, if your goal is to live longer, is a beneficial mutation. If you don't have these FOXO3 mutations that allow you to be a centenarian at 2.7 times high or likelihood than other people, deliberate heat exposure is one way that you can increase FOXO3 activity.”

“One such mechanism involves a genetic program involving a molecule called FOX 03. Fox3 is a very interesting molecule because it's involved in DNA repair pathways.”

“Sauna exposure in particular sauna exposure two to three times or ideally four to seven times per week in that 80 to 100 degree Celsius range has been shown to upregulate levels of FOX3.”

“Deliberate heat exposure is one way that you can increase FOX3 activity. There is no sauna protocol designed specifically to reduce cortisol or specifically to increase FOX3 or specifically to activate heat shock proteins. Any deliberate heat exposure is likely to impact all of those mechanisms.”

“Heat stress also activates one of the well-known longevity genes foxo3a, which happens to protect against a variety of different cellular stresses that occur with age”

“it also improves overall longevity possibly by many different mechanisms activating heat shock proteins which are important for M maintaining the proper three-dimensional structure of proteins inside of our cells and also by activating the boxo regene which is doing so much coolshit that's like really really good and really important for the way we age”

“how it activates foxo3 and how foxo3 is a really really important stress response genetic pathway that activates all these other amazing genes that help us deal with all the damage that we're constantly being exposed to and how it's involved in longevity”
