Transcription
Cold showers are all the rage. What do you think of these new trends?
My opinion is quite global. Cold is a natural element and I think it's vital that the brain can recognize these stimuli.
We have sensory receptors all over the body, including thermoreceptors. And it's going to be relevant to activate these thermoreceptors, whether with heat or cold.
And then, once again, the brain will get used to this information and say: ah, it's cold! OK, everything's fine. I'll start shaking and twitching to warm up my body.
Cold showers or cold therapy are very important, in my opinion, for achieving homeostasis of body and mind. Because the brain needs this information.
Okay for the cold shower, but what are the dangers?
Now, it's very important not to go to extremes. That's why it's important, in my line of work, to remember the middle way.
It may be too much to bathe every day, or it may not be enough to bathe at all.
You have to listen to your body, to your needs, to your intuitions and instincts.
And that's why you can quickly go to extremes, as we've seen, where you absolutely have to hold out for 20 minutes at zero degrees three times a day. It's all a question of the deep need you have.
Cold shower: Benefits
Now, the virtues of cold are numerous:
In particular, everything to do with blood circulation, the endocrine system, the immune system, physical and mental recovery, and awakening the primal instincts deep down inside.
I don't want to give a percentage, but we're very close to hunter-gatherers.
So the brain waits and our genes wait for this kind of stimulus. But be careful.
