The Health Benefits of Saunas
There are many claims about the health benefits
of saunas. They are supposed to be good for losing weight,
cleansing the body of toxins, lowering cholesterol, relieving
the symptoms of arthritis and treating respiratory problems
like bronchitis and laryngitis. Sounds like a miracle
cure, doesn't it? Some of these claims may be
exaggerated, but others may have sound scientific
foundations. Let's take a closer look.
Losing Weight
There are plenty of weight loss programs that
suggest saunas are an effective way to lose eight. They
point to the fact that when you are in a sauna your heart rate
increases and the body is working to cool itself. You may
hear a figure of 300 to 500 calories burned during a 30 minute
sauna session.
It is true that the heart rate increases during
a sauna, and it is also true that you are burning calories
because of that. But during a regular exercise session
your body is using many muscles – in a sauna the heart is the
only muscle being exerted.
Building and toning muscles is more important
for weight loss than exerting your heart. The bottom line
is: If you want to lose weight, do some exercise. A sauna
afterwards is a bonus, but it will not help much in your weight
loss program.
Toxins
'Saunas rid the body of toxins.' This
claim is made by many sauna manufacturers and retailers and it
is also a commonly held belief among sauna
enthusiasts. The fact is there is no scientific evidence
that toxins such as heavy metals (such as lead and mercury) or
other such toxins are eliminated from the body by sauna
use. These kinds of claims are heard more in relation to
Infrared saunas than traditional saunas, but either way,
there's no evidence for it.
Lowering Cholesterol
This is another dubious claim put forward by
many sauna retailers. Taking regular saunas is supposed to
reduce cholesterol without any change in the diet. There
is no scientific evidence for this.
Are There Any Real
Benefits?
After looking at some of the quackery
associated with saunas one might be tempted to write off any
claims of therapeutic value. Don't be so fast – there are
real benefits to taking saunas and their use can be part of a
regular health regime.
Physical Effects
During a sauna the heart rate increases and the
blood vessels dilate to accommodate the increased blood flow.
Blood flow to the skin increases and heavy sweating is
induced. The nasal passages open allowing the sinuses to
drain.
The heat experienced in saunas can have real
health benefits. Arthritic and rheumatic patients will
feel less pain and experience greater joint mobility. This
effect, though, will pass once the sauna is
Finished. Athletes can benefit from a sauna before working
out because the heat causes the joints and muscles to be more
flexible.
Probably the biggest health benefit of saunas
is the relaxation they induce. Our modern lives are filled
with stress and the accumulated affects of stress can be the
root of many health problems. Saunas are relaxing and calming
and provide a great way to unwind at the end of the day. A
sauna before bed promotes deep sleep – necessary for the body
to rejuvenate and recuperate.
People with health problems should consult with
their doctors before using saunas but for most the sauna is
safe and beneficial when taken in moderation.
