Sauna e benefici al cuore

LA SAUNA PROTEGGE IL CUORE!

Una recente ricerca scientifica dimostra che andare in sauna almeno quattro volte alla settimana riduce il rischio di mortalità cardiovascolare anche del 60%.

Uno studio prospettico è stato condotto su di un campione di popolazione di oltre 2300 uomini di mezza età della Finlandia orientale (presumibilmente gli stessi risultati valgono anche per le donne che comunque sono meno soggette a problemi cardiovascolari).

I dati di questa ricerca sono stati raccolti in 20 anni e dimostrano che per ottenere i migliori benefici possibili ci si deve sottoporre alla sauna - impiegando almeno 20 minuti a seduta - per quattro volte alla settimana. Tutte le azioni finalizzate alla prevenzione della malattie del cuore hanno un ruolo importante. I medicinali in genere non hanno questa capacità.

La sauna rappresenta quindi il modo più naturale, economico ed indolore per migliorare la salute del cuore!


Ricerca Scientifica: Association Between Sauna Bathing and Fatal Cardiovascular and All-Cause Mortality Events

Importance Sauna bathing is a health habit associated with better hemodynamic function; however, the association of sauna bathing with cardiovascular and all-cause mortality is not known.

Objective  To investigate the association of frequency and duration of sauna bathing with the risk of sudden cardiac death (SCD), fatal coronary heart disease (CHD), fatal cardiovascular disease (CVD), and all-cause mortality.

Design, Setting, and Participants  We performed a prospective cohort study (Finnish Kuopio Ischemic Heart Disease Risk Factor Study) of a population-based sample of 2315 middle-aged (age range, 42-60 years) men from Eastern Finland. Baseline examinations were conducted from March 1, 1984, through December 31, 1989.

Exposures  Frequency and duration of sauna bathing assessed at baseline.

Results  During a median follow-up of 20.7 years (interquartile range, 18.1-22.6 years), 190 SCDs, 281 fatal CHDs, 407 fatal CVDs, and 929 all-cause mortality events occurred. A total of 601, 1513, and 201 participants reported having a sauna bathing session 1 time per week, 2 to 3 times per week, and 4 to 7 times per week, respectively. The numbers (percentages) of SCDs were 61 (10.1%), 119 (7.8%), and 10 (5.0%) in the 3 groups of the frequency of sauna bathing. The respective numbers were 89 (14.9%), 175 (11.5%), and 17 (8.5%) for fatal CHDs; 134 (22.3%), 249 (16.4%), and 24 (12.0%) for fatal CVDs; and 295 (49.1%), 572 (37.8%), and 62 (30.8%) for all-cause mortality events. After adjustment for CVD risk factors, compared with men with 1 sauna bathing session per week, the hazard ratio of SCD was 0.78 (95% CI, 0.57-1.07) for 2 to 3 sauna bathing sessions per week and 0.37 (95% CI, 0.18-0.75) for 4 to 7 sauna bathing sessions per week (P for trend = .005). Similar associations were found with CHD, CVD, and all-cause mortality (P for trend ≤.005). Compared with men having a sauna bathing session of less than 11 minutes, the adjusted hazard ratio for SCD was 0.93 (95% CI, 0.67-1.28) for sauna bathing sessions of 11 to 19 minutes and 0.48 (95% CI, 0.31-0.75) for sessions lasting more than 19 minutes (P for trend = .002); significant inverse associations were also observed for fatal CHDs and fatal CVDs (P for trend ≤.03) but not for all-cause mortality events.

Conclusions and Relevance Increased frequency of sauna bathing is associated with a reduced risk of SCD, CHD, CVD, and all-cause mortality. Further studies are warranted to establish the potential mechanism that links sauna bathing and cardiovascular health.
