anyway sauna has its benefits..I did some research cuz I was lost myself and ppl said good things bout it here
Many non-sauna users are unaware of some Sauna Secrets, such as:
Shaving with a Trac type razor when profusely sweating in a Sauna yields an incredibly smooth result, without the use of gels or foams. This is equally true for your face and legs.
Cold Relief... Temporary relief from head or chest colds can be obtained in the Sauna. Simply pouring some essence of Eucalyptus (a natural substance) in a ladle of water onto the Sauna rocks yields a fragrant and medicinal burst of steam. Sinus and chest passages often respond favourably with improved breathing.
Socializing... Sharing a Sauna session with friends can be a great way to spend an hour or so in relaxed conversation!
Deep skin cleansing... Due to the open and closing cycle during heating and cooling phases, the Sauna helps to clean your pores deeply and thoroughly.
Take the chill out of winter! The Sauna can provide a psychological lift on a very cold winter day, when you just can't seem to get warm. This is especially useful if you're from the Great White North, like us, Eh?
Take a nap... The Sauna is a great place to have a brief nap, especially when the temperature is set relatively low, at 40° to 60°C.
Can't sleep? Well, take advantage of Sauna's relaxing effect by going to sleep after a regular Sauna Session. The Sauna will leave you in a peaceful, relaxed state, and you will probably find it much easier to doze off.
Your metabolism and pulse rates increase, your blood vessels become much more flexible, and your extremities benefit from increased circulation. Physical fitness fans will recognize that some of these changes can also be achieved through strenuous exercise. Not to say that a sauna would put you in excellent physical condition without moving a muscle (don't some of us wish!), but that it brings about the same metabolic results as physical exercise
