I've finally found the will to do it!
I too have been doing it since 1 week and half.
Of course, since 2014, I've been experimenting with cold showers,
I have taken cold shower since learning about the subject and never looked back ever since.
But never I actually was able to do the full duration according to the C's. More like quick cleaning for 2, 3 min until starting to shiver. I never stayed the course and doing it everyday.
How I usually did every year was restarting on summer on coldest setting and never touching the setting again and doing it everyday to adapt the body to the decreasing water temperature though fall and winter season.
This time, I didn't actually planned to do the full duration. My mindset was to just gradually staying in a bit more every day. Until I'm bored and stop it again I though. The early december month was unusually cold in Paris region. I don't have a thermometer but I assumed the water temperature was arround 10 to 15 on coldest setting in winter. So I was mentally counting and gradually adding +30sec everyday. Then I notice it took longer than the +30sec daily until body start to shiver so decided to just measure how long I could stand in it. I was surprised I reached 7 min !!!
It was really 'eye opening' because I didn't realize I could stay in there despite full body shivering/(tremoring??) like crazy and that I had to persist through it . Controling and relaxing the body through pipe breathing.
So learning that, the next day I say 'screw it' and instead of measuring how long, I just put 10min on phone's coundown and stay in there until It ring.
I never shivered that much in my life to the point of having to grab something for fear of... 'i don't know', 'sliping' or 'injuring myself'. Because at that point the full body was shaking and making loud noisy on the ground with my feets from the tremors every few minutes.
But I could control it with slow pipe exhalation. Also I discovered that I somewhat could stop it by moving the shower over my face/head when shaking hits.
Next days, I put the countdown to 12, 13 and finally 15minutes and kept doing it everyday except for 1 day last week.
Turns out it was/is a tough experience, and cold baths are way harder than cold showers to me. I'm more on the skinny spectrum and get cold easily when passive in a fresh environment.
I've been shaking like crazy inside and outside the pool for more than 2 weeks every day.
The sensations is really different, While before when I was only doing only a few minutes everyday until shivering , I would warm up real quick and feel good/comfy after.
While the full duration... it feels really terrible for 30min, I understand now what it was meant by feeling 'deep cold' inside your skin/bones. It's really 30min or more of intense full body shaking that I can't do anything. First day I hurt myself on the center area, some kind of deep cramp, when bending to 'try' to put socks on my feets, it was really painful. Now I just lie down on bed and wrap myself in a plaid, breath non-stop and endure until its gone.
I'm really happy with the benefits. I noticed right away my upper body temperature is way up. Also on the first days, I woke up one night, sweating like crazy around the neck, I was still wearing warm clothes. Since then I sleep with only my underwear under a plaid and I'm fine. And I don't even use heating.
Most importantly I'm happy that I still haven't gotten sick from the flu. I always caught it every year no matter what I try to avoid it. I also feel much stronger mentally. After all it is my main motivation for doing it : stronger immune system and stronger will.
Now I feel immense dread to go into it everyday, procrastinating and delaying the time.
While before, 2minutes shower was a 'piece of cake' if I didn't wanna, I could just trick myself into doing it by telling myself, "go for just a real quick one and you're done for the day"
. It's a different story when mind know you have to stay for 10minutes in + enduring 30minutes of intense shaking.
Still 1week and a half to go until I 'only' do it every other day
I'm kinda hoping the temperature decreases again like in early december, so that I wouldn't have to stay that long.
