Regular sauna use supports detox, heart health, and healthy ageing.
Who is behind it
Voices including a licensed acupuncturist and clinician-educator, a molecular biology PhD and a Princeton-trained molecular biology PhD.
How strong the research is
Backed by some published research, and by what the experts see in practice.
In their words
“doing sauna frequently reduces your probability of dying from all causes... frequent sauna use results in reduced risk of stroke of heart attack of Parkinson's of Alzheimer's”
a licensed acupuncturist and clinician-educator
Sauna-induced sweating is the most effective and least energetically costly way to eliminate toxins from the body compared to other heat therapies or exercise sweating.
having a sauna is good for cardiovascular health and builds infrared energy which supports fourth phase water essential for cell function
Sauna and red light panels are generally good for mitochondrial health and structured water in the body
Sauna is described as the ultimate longevity hack and beneficial for detoxification by raising body temperature and stimulating the lymphatic system.
Sauna is mentioned as a tool for warming and supporting flu recovery.
4+ sauna sessions per week reduced cardiovascular death by 73%
Sauna 3x per week is necessary not optional due to GSTM1 gene deletion affecting detoxification.
