They’re more than relaxing. Research shows saunas can be good for your health
- Washington Post, 9/9/18 - "The Mayo Clinic Proceedings
recently published a paper titled “Cardiovascular
and Other Health Benefits of Sauna Bathing: A Review of the Evidence.” The
researchers conclude: “Emerging evidence suggests that sauna bathing may be
linked to several health benefits, which include reduction in the risk of
vascular diseases such as high blood pressure, cardiovascular disease, and
neurocognitive diseases; nonvascular conditions such as pulmonary diseases;
mortality; and amelioration of conditions such as arthritis, headache, and flu.”
... The studies typically included subjects who spent five to 20 minutes in a
sauna heated to 175 to 210 degrees Fahrenheit, followed by a swim, shower or
return to room temperature. Sauna exposure raised subjects’ heart rates to 120
beats to 150 beats per minute and increased blood flow to the skin, much as
moderate exercise does" - Note: You're lucky to get 125 degrees out
of most of the home saunas that you buy in America.

Saunas May Reduce Stroke Risk - NYT, 5/2/18 - "After
adjusting for other variables, they found that compared with people who took
saunas once a week, those who took them two to three times weekly were 12
percent less likely to have a stroke. People who took saunas four to seven times
a week reduced their risk for stroke by 62 percent" - See

Scientists uncover why sauna bathing is good for your health - Science
Daily, 1/5/18 - "Immediately after 30 minutes of sauna
bathing, test subjects' mean systolic blood pressure reduced from 137 mmHg to
130 mmHg, and their diastolic blood pressure from 82 mmHg to 75 mmHg.
Furthermore, their systolic blood pressure remained lower even after 30 minutes
of sauna bathing. Test subjects' mean carotid-femoral pulse wave velocity, which
is an indicator of vascular compliance, was 9.8 m/s before sauna, decreasing to
8.6 m/s immediately after ... The benefits of regular sauna bathing on cardiac
health observed in the population-based study can, according to this
experimental study, be explained by the fact that sauna bathing reduces blood
pressure and increases vascular compliance"

Frequent sauna bathing keeps blood pressure in check - Science Daily,
9/29/17 - "The same researchers have previously shown that frequent sauna
bathing reduces the risk of sudden cardiac death, and cardiovascular and
all-cause mortality ... The risk of hypertension was 24% decreased among men
with a sauna frequency of 2-3 times a week, and 46% lowered among men who had a
sauna 4-7 times a week .. Sauna bathing may decrease systemic blood pressure
through different biological mechanisms. During sauna bathing, the body
temperature may rise up to 2 °C degrees, causing vessels vasodilation. Regular
sauna bathing improves endothelial function, i.e. the function of the inside
layer of blood vessels, which has beneficial effects on systemic blood pressure.
Sweating, in turn, removes fluid from the body, which is a contributing factor
to decreased blood pressure levels. Additionally, sauna bathing may also lower
systemic blood pressure due to overall relaxation of the body and mind"

Sauna Bathing and
Incident Hypertension: A Prospective Cohort Study - Am J Hypertens. 2017 Jun
13 - "In Cox regression analysis adjusted for baseline
age, smoking, body mass index, and SBP; compared to participants reporting 1
sauna session per week, the hazard ratio for incident hypertension in
participants reporting 2 to 3 sessions and 4 to 7 sessions was 0.76 (95%
confidence interval: 0.57-1.02) and 0.54 (0.32-0.91), respectively" - See

Frequent sauna bathing protects men against dementia - Science Daily,
12/16/16 - "the study participants were divided into
three groups: those taking a sauna once a week, those taking a sauna 2-3 times a
week, and those taking a sauna 4-7 times a week ... The more frequently saunas
were taken, the lower was the risk of dementia. Among those taking a sauna 4-7
times a week, the risk of any form of dementia was 66% lower and the risk of
Alzheimer's disease 65% lower than among those taking a sauna just once a week
... Previous results from the KIHD study have shown that frequent sauna bathing
also significantly reduces the risk of sudden cardiac death, the risk of death
due to coronary artery disease and other cardiac events, as well as overall
mortality" - See JNH Lifestyle saunas at

Acute effects of sauna
bathing on cardiovascular function - J Hum Hypertens. 2017 Dec 21 -
"We
conducted an experimental study including 102 participants (mean age (SD): 51.9
(9.2) years, 56% male) who had at least one cardiovascular risk factor.
Participants were exposed to a single sauna session (duration: 30 min;
temperature: 73 °C; humidity: 10-20%) ... This study demonstrates that sauna
bathing for 30 min has beneficial effects on arterial stiffness, BP, and some
blood-based biomarkers"
