I only use infrared sauna. I use Trisana because research shows it is more effective at driving blood flow and heavy sweating without overheating the body. I just wear normal clothes. I wear 100% cotton to avoid reabsorbing the toxins my body's excreting. I just like to sit there until I feel like it's enough. I follow a protocol of three to five sessions per week. 20 minutes and the temperature between 175 and 212 degrees Fahrenheit. I don't use any protection. I use an ice pack on my boys that is BPA free because the heat destroys my fertility markers. You know, you're really annoying, but anyways.
