But it does appear that both for men for reasons I talked about a few minutes ago and for women that deliberate cold exposure can be beneficial for fertility and for hormone production . But in particular for females , in terms of regulating cortisol and for hormone production . Now , you might say , ok , getting into cold is stressful .
Not because cold is good for the ovary or being cold is good for the ovary or for luteinizing hormone or for follicle stimulating hormone or anything else like that . But rather that using deliberate cold exposure as a way to restrict stress in a deliberate way to a particular time of day , increases the release of cortisol then and indirectly reduces the amount of cortisol that's released at other times along the 24 hour cycle . Ok .
So I would say , you know , not too close to sleep . Then what you do is you restrict your maximum cortisol released to a period earlier in the day that buffers reduces . That is the likelihood that you would have excessive amounts of cortisol later in the day , which not only can disrupt sleep but is correlated with a number of other um hormonal effects that are not good for us and therefore not good for fertility .

So here what I'm describing are positive yet indirect effects of a cold on hormone levels , both in males and in females .
Now , you might say , ok , getting into cold is stressful . How can that be helpful for regulating stress ? Well , it turns out when you get into the cold , you get a big surge in adrenaline and then dopamine , which is very long lasting provided that's done in the early part of the day .
