It was quite easy at first as it was at the peak of summer in which the temperatures were around 33-38 degrees Celsius. I could simply take cold shower for several times in a day, no sweat.
But it's getting difficult now as the winter has just come and due to the which the temperatures drop to about 15 degrees Celsius, which is not that low yet but I already felt it was like experiencing a torture.
In general, the first I would do in a day is taking a cold shower. I would go straight into the bathroom with my sleepy status after I just wake up, and open the cold water and drop on my body. It's always painful and exciting, which I would feel like I am being pulled out from my unawake body and I would start breathing rapidly because my body is trying to adopt that low temperature from the water. I have to say it's a faster way to wake myself up compared with just having a cup of black coffee.
I'm going to see what extent that I can endure, for which I can also learn how to keep challenging myself everyday because it seems to me that it's something you can't really get used to. It won't be like in a day you can finally say 「Alright, it can't bother me anymore.」
Instead, it always stimulates us mentally and physically, and we just have to make ourselves to go through in it until we temporarily adopt it, and in return, we earn those benefits simultaneously.
