The health benefits of using the FIR Sauna

  • Detoxification
  • Muscle Relaxation
  • Improved Cardiovascular Health
  • Speed Recovery from Injuries
  • Improved Immune System

Why Is FIR important to the human body? 
FIR has the ability to penetrate, refract, radiate and reflect. The human body can absorb FIR because of its deep penetrating ability. When FIR penetrates through skin to the subcutaneous tissues, it transforms from light energy into heat energy. The thermal effect within the deep layers of the tissues causes bloods vessels and capillaries to dilate, promoting a better blood circulation, and the heat so produced helps to get rid of body toxins and metabolic wastes through sweating.

We are exposed to numerous toxins on a daily basis. The body primarily deals with these toxins through the liver, kidneys and intestines; however toxins in the form of xenoestrogens, found in many cosmetic and cleaning products that come in contact with your skin, bypass these mechanisms and enter the bloodstream wreaking havoc on your system and causing unsightly fat storage. Hence the need for a detox. There are many ways to detox whether through nutrition or supplements. The FIR sauna aids in detoxification by warming the body and allowing you to sweat. Analyses of the sweat of individuals after sauna use indicate higher levels of heavy metals and solvents excreted than sweat through exercise alone.

The heat from the sauna helps to relax muscle.  Complementing sauna with aggressive stretching will help to increase mobility faster than simply stretching by itself.  The heat from the sauna also causes dilation of the blood vessels and increased blood flow to all parts of the body. Increased blood flow increases the flow of oxygen and nutrients essential for tissue repair and can help with injury recovery as well as reducing mean arterial blood pressure.  Additionally, heating may help to kill off bacteria and viruses inside your body thus supporting immune function.

How to Sauna
Sauna use has a cumulative effect on the body.  You will get benefits from using the sauna one time, such as improved mobility and detoxification- to a certain extent. However the sauna will provide a greater benefit if used on a recurring basis.  Start with 3 days a week and see how you respond. After the first few weeks increase as you feel necessary.

Sauna use should not be a source of stress; do not treat it as such. If you can’t spend more than 5 minutes in the sauna without feeling cramped and frustrated, then use it in 5 minute increments- step out for a minute, cool off and get back in. You should at least spend long enough inside to break a sweat, even if it is in short increments. The last thing you want to do is increase cortisol levels doing something that is meant to be relaxing. Most of you will be just fine in the sauna for 15-20 min at a temperature of 120-130 degrees.  If you are attempting to improve mobility try alternating sauna to stretching then back to sauna.

The sauna is free to all for the rest of the month. Take advantage of it today before and after our mobility work and use it as much as you like until the end of the month. It is a great addition to any of you trying to improve mobility or rid your body of estrogens and environmental toxins.  If you’ve never used the sauna before, try it out and you’ll be glad you did.

    Two of my favorite things….sauna and kids kamp.

    Kids Kamp is so much fun. The kids are awesome and super cute. Kaden, shown above, is a beast. He can do clapping push ups, move weight around, and do L-sits better than most. A lot of our campers are lifting better than their parents. They have great form. They are all doing a super job listening and they always try their best. Thank you for sharing your awesome kids with me this week. We are having a blast.

    Sauna….my addiction. I love it. I get in the sauna every chance I get. Try it out…detox…..get your sweat on! You will feel great.

    I just want to say a little something about rolling out, stretching and using those little orange balls:
    As an instructor I tell everyone to stretch and roll, and only do it half (Hell, maybe a sixteenth) of the time I should. Last Wednesday I participated in Meagan’s class on stretch and foam rolling. Taking the class MADE ME take the time and do the proper movements. Since that class I have made a point of rolling out and stretching before and after EVERY workout. It also helps that my ass is old and it’s near impossible to do any WOD without really warming up these days! Anyhoo….If you have been only partially paying attention to the latest posts and requests to participate in these more chilled out but equally as important classes, I URGE you to make yourself get into the gym and just do it. Its one of those things you might have to make yourself do, but I guarantee you will be happy you did it. Monday’s deadlift workout did a job on my weak lower back. Normally I would be crippled for a good two days. I rolled out and got my groove on with that orange ball up against the wall–and let me tell you what–PAIN FREE the following days. This stuff works. Do yourselves a favor and give it a go. Pretend its New Years…make a resolution to stretch and roll that body you love beating up so much! Start today, its Wednesday. Take a class. Don’t be lazy.

    I am always amazed at the lack of participation in the stretching and myofascial days. I look forward to these rest and recovery days personally. Part of my goals are to improve flexibility and form and the IT Band and Hip flexor work you can do while making sweet magic to those foam rollers is great for that.

    From the WODs to the WSC I can tell a huge difference in fatigue and muscle soreness when I don’t have the ability to roll out after a workout.

    However, with everyone sitting out it was nice to have the sauna not feel like I was packed in tight as a sardine. 🙂 We do need a radio or something in that hotbox though.

    3 people at the 11:30 class for an excellent MR session with Josh. Considering that class time is usually packed, only 3 people is a BAD TURNOUT!!! Interestingly the participants were all over 35. Just because you may feel it more when you’re older doesn’t mean it isn’t helping. I agree with Taylor’s post, get yourself in for the ‘easy’ stuff. I feel awesome right now and I was sore this morning. I am so glad I went and thank you Josh for not rushing through even though you are about to go party down. Also, a huge thank you to Meagan and all the CIT’s at kids camp. It is an excellent program. Anyone who was on the fence about sending your kids this year, I highly recommend it and you should send your future CF games winners next year for sure! Kaden is so beastly, I love it!

    Meagan, Several months ago Josh stated there would be a 9am kids class offered on Tuesay and Thursday mornings during the summer. I have not seen any posts about this so I thought I would inquire. Thanks!!

  7. Meagan says:

    Stephanie….YES. I am excited. Starting next Tuesday, June 26 there will be a 9 am kids class every Tuesday and Thursday. Classes will be roughly an hour long. $ 10 drop in fee or we have class cards available for purchase. $ 75 for 10 classes $ 100 for 20 classes.

    This Saturday , I will be.out of town. Kids classes will pick up the next Sat. June 30. Kids 4-7 from 8: 30-9 & kids 8 and older 9-10. I really enjoy working with all of our CFW fun sized beasts!!!

    Megan, thanks for taking the time to help w/ the kids of CFW. I know that as a parent we all strive to lead our kids down the path of a healthy lifestyle and it only helps when you have people like yourself that assist in doing so and more importantly – make it fun. Both he & his sister have loved coming to the kids classes on Saturdays & even doing this camp. My wife and I try to be positive role models to our children and it always helps when you have an incredible person like yourself that we know will be an equally positive influence. I am going to miss everything about CFW when we leave but I know my kIds will miss the box as well. Thanks again!
