Our typical gym routine goes something like this: Get sweaty with some cardio, hit up a few weights, stretch out, and then head straight for the showers. Good enough—or are we missing something?
Almost every gym in America has a sauna or steam room, but they’re usually neglected as we sprint past them for the treadmill and weight room. To most of us, a stint in the sauna may seem an indulgent treat, like a festive holiday beverage, rather a necessary part of our wellness routine.
But the opposite is true in other cultures where the benefits of sauna time are considered vital to health. In Finland, sauna tradition dates back to the 12th century, and the country is still crazy about saunas: Finland boasts approximately one sauna for every three people, and 99 percent of Finns sauna it up at least once per week! A bunch of other cultures have their own versions: the Turkish hammam, Russian banya, and Korean Hanjeungmak, to name a few. While each has a unique take on the hot and/or steamy room concept, all emphasize its cleansing and healing properties. Could these cultures be on to something?
Breaking a Sweat
“Sauna” and “steam room” tend to be used interchangeably in the U.S., but there are a few differences between the two. A sauna gets super hot—between 160 to 200 degrees Fahrenheit—and has low humidity, while a steam room runs at a more reasonable 110 to 120 degrees.Steam rooms, as the name implies, also have much higher humidity.
While a hard workout can leave us dripping wet, saunas and steam baths provoke the same physical response without the effort. During exercise, body temperature rises and a response system kicks in to avoid overheating. Circulation picks up, blood flow goes to the skin, and sweat pours out—all in the name of keeping us cool
Rumor Has It…
A number of popular claims exist regarding the health benefits of steam rooms and saunas, but many lack strong scientific backing. Sweating has traditionally been regarded as a cleansing practice that offers numerous health benefits
Weight loss is another draw for sauna-goers. Although some calorie-burning claims exist, they’re likely exaggerated. Some research shows that exercising in the heat may boost metabolism by a small amount—but probably too small to cause a big boost in caloric burn
Steamy Science
Although sweating it out in a hot room isn’t the magic bullet for weight loss or squeaky-clean insides, sauna therapy may offer some real benefits to both healthy people and those with chronic disease such as hypertension, diabetes, and heart failure
A few recent studies suggest that regular sauna therapy may strengthen vascular function, lower blood pressure, and improve insulin sensitivity
Those of us without chronic disease can also benefit from sweating it out. Several studies with healthy young men and women as subjects demonstrated a decrease in LDL cholesterol (the “bad” cholesterol) and in total cholesterol after several weeks of sauna bathing
And here’s more good news for sauna lovers: There’s some scientific evidence indicating that regular sauna sessions enhance athletic performance. One small study found that three weeks of post-exercise sauna time increased athletes’ endurance capacity, likely by increasing blood volume
Even if lowering cholesterol or post-workout recovery are not on the agenda, we could all use a little R & R. Ample anecdotal evidence (and first hand “research” by the present writer) supports the claim that saunas and steam baths offer a great way to relax and reduce stress.Since “relaxation” is pretty subjective, there’s not a whole lot of strong science on the subject. However, one research study found that in depressed patients, sauna use led to higher levels of relaxation and reduction of other mental symptoms
The Takeaway
Those in search of a detox or weight-loss magic bullet, look elsewhere. But for people looking to improve heart health, boost athletic performance and recovery, or just relax, a sauna or steam room might be worth checking out. Research is still limited and lots more needs to be done, but sweating it out (without the workout) appears to be safe and beneficial for most people as long as they follow a few guidelines:
•Skip the booze before and after
•Keep it to 15 to 20 minutes
•Hydrate before and after (a couple of glasses of water should do the trick)
•Head for the door if you start to feel sick or dizzy
