heat exposure shifts autonomic nervous system balance for up to 3 hours after a session
Dry-sauna treatment significantly increased the sympathetic-parasympathetic balance ratio of the diastolic blood pressure spectrum (LF/HF-dBP) from 6.1 to 13.2 (P=0.0029), persisting for up to 3 hours post-exposure.
What this means for you
Your autonomic nervous system controls how your body handles stress, recovery, and rest. A shift in its balance after heat exposure suggests your body is actively recalibrating — something many people notice as a calmer, more settled feeling in the hours that follow. Supporting this balance regularly may contribute to better stress resilience and cardiovascular ease over time.
