Besides the obvious exhilarating effect steam provides after a grueling day at work, there are many therapeutic benefits as well. In the simplest terms the inhalation of steam is the practice of inhaling moist, hot air into the lungs through the throat and nasal cavity for therapeutic benefit. Quite often people will add essential oils for additional therapeutic relief as well. It’s no wonder ancient civilizations used community baths as a vehicle to remedy public health issues. Among the many benefits steam has on the human body is that it boosts the immune system by increasing the white blood cell count. Since white blood cells are your body's first defense against disease steam can literally help you avert the common cold as well as other diseases such as pneumonia, influenza, bronchitis, allergies, and asthma. Not only will a steam treatment help you avoid coming down with disease it can also assist you in ridding existing conditions. Just as you would put a vaporizer into your child's room to emit steam into the air, a steam room replicates this effect by relieving nasal congestion, sore throats, and excessive coughing.
