Plain-English Summary
Frequent sauna bathing was associated with lower fatal cardiovascular and all-cause mortality in this cohort. The result is important but observational and should not be written as causality or a universal protocol.

How the study framework works ->Key Findings
- Frequent sauna bathing was associated with lower fatal cardiovascular and all-cause mortality in this cohort.
- The result is important but observational and should not be written as causality or a universal protocol.
Limitations
- Male Finnish cohort limits generalizability.
- Residual confounding and healthy-user effects remain possible.

Sauna, Cold Plunge, and Contrast Therapy: Hormesis or Heart-Stress Theater?
Sauna has a stronger long-term cardiovascular and mortality signal than most cold-plunge claims. Cold exposure has acute physiology, mood appeal, and recovery tradeoffs. Contrast therapy adds ritual, but not automatic evidence.

sleep: Sleep duration is associated with all-cause mortality in a
Sleep duration is associated with all-cause mortality in a U-shaped pattern in prospective cohort meta-analysis, with both short and long sleep linked to higher mortality risk versus roughly 7 hours, but causality is not proven.
sleep: Objective sleep regularity is associated with all-cause and cause-specific
Objective sleep regularity is associated with all-cause and cause-specific mortality risk, and may capture a health-relevant sleep dimension that average duration alone misses.
semaglutide: Semaglutide reduced major adverse cardiovascular events in SELECT participants
Semaglutide reduced major adverse cardiovascular events in SELECT participants with overweight or obesity and established cardiovascular disease without diabetes.

GLP-1-based therapies have demonstrated outcome benefits beyond weight loss in specific high-risk cardiometabolic populations.
vegan diet: Vegetarian and vegan diets can lower LDL-C and apoB
Vegetarian and vegan diets can lower LDL-C and apoB on average in randomized trials, especially when they improve saturated-fat and fiber patterns.
