Acclimating your body to heat stress by intermittent whole-body hyperthermia via sauna use (“hyperthermic conditioning”) has been shown to:
- Increases the storage and release of norepinephrine, which improves attention and focus.
- Increases prolactin, which causes your brain to function faster by enhancing myelination and helps to repair damaged neurons.
- Increases BDNF, which causes the growth of new brain cells, improves the ability for you to retain new information, and ameliorates certain types of depression and anxiety.
- Causes a robust increase in dynorphin, which results in your body becoming more sensitive to the ensuing endorphins.
