There are wellness tricks that seem too ridiculous to work. This was one of them: sticking your face in a bowl of ice-cold water first thing in the morning.
I had read that cold exposure on the face can activate the so-called diving reflex, linked to the autonomic nervous system and a reduction in heart rate.
So I decided to stop reading about it and test it firsthand for two weeks. This is what I noticed.
The first day I understood why almost no one wants to do this upon waking
My routine was simple: a bowl, cold water, a few ice cubes, and my face inside for about 15 seconds.
Simple, yes. Pleasant, not so much.
The first contact with the icy water produced exactly what you would expect: an immediate rejection reaction.
The cold on the face made me want to pull my head out at once. But after a few seconds something strange happened: the initial impact sensation began to transform into calm.
And here’s the interesting part. The facial immersion in cold water can trigger the so-called diving reflex, a reflex involving the autonomic nervous system that can lead to a decrease in heart rate.
It wasn’t a feeling of euphoria or a rush of energy. It was more like someone had pressed the pause button on my brain.
By day four, I began eagerly awaiting the moment to put my face in ice
The early days I had to force myself.
Then something unexpected happened: I started doing it automatically.
Normally, upon waking, my head fills with thoughts before I even step onto the floor. Pending messages, things to do, work, worries… The cold water interrupted that chain.
During those 15 seconds I couldn’t think too much about anything.
There was only the cold.
And then came a sense of calm that, at least in my case, made starting the day feel different.
The physiological explanation makes sense: cold on the face stimulates nerve endings related to the diving reflex and may increase parasympathetic activity, though the response varies greatly from person to person.
Moreover, there was a side effect I liked even more: my face looked less puffy in the mornings.
Two weeks later, this is what really changed
Did I become a completely relaxed person? No.
Did the stress disappear? Not either.
Did the ice water “reset” my nervous system? That claim would be too grand for what we actually know.
But something happened that I didn’t expect: it changed how I started my mornings.
The ritual was so brief that I couldn’t make excuses. I didn’t need to carve out half an hour to meditate or follow a complicated routine. I only had to fill a container and hold it for a few seconds.
And above all, I discovered that the goal wasn’t to endure the cold for as long as possible. There’s no need to turn it into a endurance challenge.
In fact, the cardiovascular response to facial cold can be intense and variable, so it isn’t a practice to be taken lightly, especially for people with cardiovascular problems.
After two weeks, my conclusion was much simpler than I expected: ice-cold water didn’t solve my life, but it did manage to shift the way I began the day.
And that, for a habit that lasts barely 15 seconds, struck me as quite remarkable.
