Research

The cohorts and trials behind the numbers, and what they actually found.

1. The Finnish sauna cohorts, and what they actually found 2,315 men, 20.7 years, and a hazard ratio of 0.37 for the most frequent users. Observational, self-reported once, and not a prescription.
2. Hot baths: 30,000 people, 20 years, and one lab trial Almost-daily tub bathing went with 28% lower cardiovascular risk than zero to two a week. A separate trial measured what eight weeks of 40.5 °C baths did.
3. Does a sauna burn calories? The most-quoted figure, about 400 kcal an hour, came from heart rate monitors, and its authors call that a limitation. Here is what heat does to it.
