The KIHD Research On Sauna Use will Amaze
In the 1980s, researchers in Finland tracked 2,315 men over 20 years. What they found about sauna use changed the conversation about preventive health: → 65% lower risk of dementia and Alzheimer's in men who sauna-ed 4–7x per week → 46% lower risk of cardiovascular mortality → 63% lower risk of sudden cardiac death This wasn't a wellness blog. This was the Kuopio Ischaemic Heart Disease study, published in Age and Ageing by Oxford University Press. We don't sell saunas as a medical treatment. But we do believe that how you choose to spend your evenings — every evening — compounds into something significant over a lifetime. Four sessions a week. Twenty minutes of heat. That's the habit the research points to. Our Finnish outdoor saunas with Harvia heaters are built to reach the temperatures used in that research: 79–100°C. That's authentic Finnish heat — not infrared, not warm air. Learn more at puresweatsauna.co.nz the 1980s, researchers in Finland tracked 2,315 men over 20 years.
