Science-Backed Insights
At BW Sauna, we’ve always believed in the power of heat. But for this new blog series, we didn’t want to rely solely on personal stories or superficial sources of information. This time, we’ve delved into decades of scientific studies, expert opinions, and research to bring you the clearest view yet of the true health benefits of sauna.
Does the sauna really help combat stress?
Sauna bathing has been shown to meaningfully lower stress levels by influencing both the body and the brain. Heat exposure activates your parasympathetic nervous system, the “rest and recover” mode, which naturally brings the body out of a stressed state.
A study published in the Journal of Human Kinetics (2018) found that a single sauna session significantly reduced cortisol levels (your primary stress hormone) while increasing relaxation markers afterward. Participants not only felt calmer, but their bodies showed measurable stress relief.
