But more so the impact on brown fat stores , which are good for us so called brown fat thermogenesis . There's a lot related to deliberate cold exposure and we've done entire episodes on deliberate cold exposure . Again , you can find that at Huberman lab dot com , we did a guest episode with an expert on the use of cold for health and performance with my colleague Craig Heller from Stanford Department of Biology .
Now , there there are fewer data to look to unfortunately . But what we do know is that deliberate cold exposure done in the way that I just described 1 to 3 minutes a day . Ideally early in the day through cold shower immersion up to the neck doesn't have to be an ice bath .
So a lot of interesting data coming out in really good journals that are peer reviewed and so on in humans . I should mention those studies are done in humans to support the use of deliberate cold exposure . But again , if you're going to use deliberate cold exposure to improve sperm quality , can it work ?
Again , you can find that at Huberman lab dot com , we did a guest episode with an expert on the use of cold for health and performance with my colleague Craig Heller from Stanford Department of Biology . We also have a tool kit on how to apply deliberate cold exposure for health , for both females and for males , for sports , performance , cognitive performance , mood sleep , et cetera . You can find all that again .
Not because there's any sort of magic effect of cold on the testicle . Now , I have to imagine that a number of you in particular females listening to this are going to say is deliberate cold exposure . And for that matter is deliberate heat exposure like sauna hot tub good or bad for the ovary for eggs and for fertility .
