Re: Cryogenic Chamber Therapy
The physiological reaction to very cold temperatures is very interesting and intriguing indeed. We are very interested in testing cold adaptation as a potential treatment and between all of us, we have a good selection of conditions and body types to work with. We are trying to collect as much data as we can and we will be writing an article about it. So please, keep us updated if you tried or are trying this therapy. We had the opportunity to find a cheap off season place nearby a cryotherapy center that saved us the traveling money and we got a very good discount on the treatments since it is a relatively new center and we signed up as a group. As part of our ongoing experiment, I completed 11 sessions of cryotherapy.
First, we needed a medical certificate in order to do cryotherapy and it seems that if your Body Mass Index is below the lowest normal range, you can't do cryotherapy:
Below 18.5 Underweight
18.5 -24.9 Normal
25 - 29.9 Overweight
30 & Above Obese
BMI =
weight in kilograms

height in meters²
My BMI was 19.19 when I started and I did 2 sessions per day for almost 6 consecutive days. The first day I got in, the machine broke and it stayed at -60 degrees Celsius which made me shiver like crazy. Perhaps it was a blessing in disguise, the protocol I followed during the next few days didn't necessarily include an adjustment period of -60 prior to the -170/-180 degrees Celsius temperatures. The sessions lasted 2 and half minutes for the first and second sessions but 3 minutes for the rest of the sessions. Since the technicians were adjusting parameters and temperatures in the machine while I was inside, I was probably exposed to too much cold too early as well.
The chamber is shaped like an open cylinder where your head stays out. It was a cryotechno machine pretty much like this one:
The lowest temperature is the temperature around your legs and the highest temperature is the one at your shoulder's level since the nitrogen falls to the lowest parts of the chamber. By the 10th session, the lowest temperature indicated -194 degrees, I don't know how accurate that is though. Still, it was pretty cold!!
Sometimes I felt like I didn't quite recovered from the last session when I was already going in for the next one. In the third or fourth session, the temperatures were at 175 degrees since the first few seconds and I had to step out at 2'40'' because my legs felt like they were catching on fire, literally! That day I slept pretty crappy and I had a red patch of skin on my ankle. I don't recall my skin surface temperature for that session, but the next one, it showed that I had -3 degrees on my legs which didn't made the physiotherapist happy. He kept asking me how my legs were doing in the next sessions, but amazingly enough, it seemed that my body started adjusting immediately after that and I was able to increase my leg temperature by 1 or 2 degrees per session until my final reading which was of 4 and 5 degrees on my legs. I also wore thick and almost knee length socks after the burning session experience since it made no sense to me to expose my legs to -180. But by the last two sessions, I wore small and thin socks without problems.
At the beginning, the fight and flight experience made me move around, marching, "dancing", even singing in order to endure the experience better. I practiced breathing exercises and felt more comfortable with deep breaths where I exhaled forcefully. After stepping out of the cryo chamber, I felt like a pressure was lifted off my chest and felt energized for an hour or two, only to feel extremely tired and sleepy for the rest of the day, especially at the beginning. Also, I felt pains that I never had before. That, plus the feeling of extreme sleepiness and tiredness made me doubt the effectiveness of the cryotherapy.
So the first 8 sessions were not necessarily something to look forward to. The feeling in your body is a combination of frozen dried air and stinging on your skin, especially on my legs and arms where I have the least fat. But it seems I reached a threshold of some sort and by the 10th I was looking forward to it and by the 11th I realized I was going to miss the experience. By the last sessions, I was doing -180 (the lowest temperature) for 3 minutes. I did the last two sessions spaced out by only one hour without any problem. This would have been completely impossible the first day. It is amazing how your body adapts so fast! I was taken cold showers without any problem by the last day.
Half way through, I started going down into the chamber so I can get cold in my face, neck and especially my shoulders where brown adipose tissue is supposed to be activated. I held my breath and closed my eyes in order to avoid the nitrogen. At some point, I stayed underneath so long that my ears felt numb and super cold and my forehead temperature read 22 degrees. During the last sessions, I stayed more still in order to get colder and tensed the muscles on my legs in order to relieve the stinging feeling.
I was also more hungry and had to eat much more in order to feel satisfied. I also woke up earlier and so famished that I had to eat right away otherwise I felt like my stomach was going to "autodigest" itself. I felt restful in between sessions and my mind felt sharper and very aware.
I noticed also that my skin was smoother and nice, and eating meats with spices didn't made me itch nor have allergies like I usually have. As a test, I ate the very spices I know will through me into a hay fever episode and nothing happened. During the last nights, I've been having vivid interesting dreams, the last one been of bright lights making viral-DNA patterns in a starry sky :P
I'm also going more regularly to the toilet, pretty much every time I eat and the consistency is perfect. I felt cramping in my muscles, but they eased with water. I was probably very dehydrated since I was very thirsty. By the end of my sessions, my muscles felt more toned/firm and pains that the cryotherapy brought initially were gone. I also have more energy and feel more present in my body.
After 11 sessions my BMI was of 18.81, but I definitely didn't lost muscle mass which I actually increased by perhaps 1 percent (they have a machine that can give you a rough estimate of your percentage of fat, water and lean muscle). Even though I "shrank", I was able to endure the cold without a problem and I'm still within a normal BMI range. Between water loss and possibly some fat loss, I think I can recover my weight and perhaps even increase it if I start lifting weights and make sure to drink enough water.
In the cryotherapy center we went, there was only two more people doing therapies. One elderly woman who had fibromyalgia who reported having benefits only after around the 15th session. Then another man in his 40s who was doing it for his rheumatoid arthritis. I think he did 20 sessions and reported seeing significant benefits only during the first week. Keep in mind that these people have an awful diet. Ailén spoke to some length to the woman about the diet and she was willing to give it a try. There was a report of someone doing it for his psoriasis problem and another person completing 30 sessions (if I recall correctly) which healed a cervical problem he had.
So that is the story. It is a very interesting physiological reaction indeed.
The following paper: http://www.uscryotherapy.com/assets/studies/knight.pdf
seems to suggest that iced water is as effective as cryotherapy and more of a shock to the body. But Dr. Kruse's protocol sounds safer because a few more minutes than the safe range and you are dead, same with cryotherapy. Careful monitoring of the body's temperature, including skin surface temperature has to be made, and also of the "cold medium". Also, someone has to be there with you in case something happens and you can't step out of the water. Say you faint from the shock or slip on the ice and knock your head... With cryotherapy you can step out at any moment you want with ease and quickly and your body starts warming up immediately. That is not the case with iced water where your body needs much more time to warm itself up (5 to 10' in the study, and they only immersed one part of the body) which makes it more difficult. Subjectively speaking, cryotherapy seems to be easier to do than cold iced water as well.
But if cryotherapy is not an option, knowing that water conducts cold much better, Dr. Kruse's protocol sounds like a very good option. Also, it makes more sense to do this as a long-term process or where you can have cold adaptation "reinforcements" depending on how you feel. So I guess we'll keep reporting and experimenting. Now that I know how cryotherapy feels, I'm interested in following Dr. Kruse's protocol and see how it goes. I'm also opened minded about iced water ONLY IF I can guarantee security measures and monitoring to make it safe.
