Show HN: Saunas lower nighttime heart rate more than exercise (n=59,000) ---- - 9 minutes ago | 12 points | 1 comments - URL: https://tryterra.co/research/sauna-effect-on-heart-rate - Discussions: https://news.ycombinator.com/item?id=47834184 - Summary: Terra Research analyzed data from 256 wearable users to study sauna effects on heart rate recovery. The study found that sauna days showed significantly lower minimum nighttime heart rate (average 3bpm decrease) compared to non-sauna days, even after accounting for higher activity levels typically associated with sauna use. This suggests saunas provide genuine physiological recovery benefits beyond exercise alone. However, the effects differ by sex: women showed greater activity increases on sauna days but smaller heart rate reductions than men. Additionally, female users only experienced meaningful heart rate benefits during the luteal phase of their menstrual cycle, with minimal effects during the follicular phase. The findings indicate heat exposure promotes recovery through parasympathetic nervous system activation, though timing may be crucial for women.
