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 .
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 . So for men , we talked about increased testosterone , improved sperm quality .
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 .
I do that mainly for the psychological effects related to the long lasting increases in dopamine and epinephrine . But there are other data starting to come out showing that that that sort of approach or similar approaches can increase testosterone levels and maybe even sperm counts can reduce cortisol late in the evening if the cold exposure is done early in the day , so on and so forth . So a lot of interesting data coming out in really good journals that are peer reviewed and so on in humans .
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 .
