Can Cold Showers Give You Superpowers?
July 4, 2023
Study after study has shown that hopping in the shower and turning the handle towards C can have tremendous benefits.
It’s claimed that doing this can boost your mood, enhance metabolism, and increase focus. One experiment even found that ice baths and breathing exercises can reduce the impact of illnesses like E. Coli.¹
But why? And more importantly before you dive into a frozen lake, how?
The science of cold showers and ice baths is actually pretty simple.
Cold showers suck. They feel terrible. The first drops of arctic water that blast your back or face seem to turn off your brain. Your heart starts racing. Your vision may get blurry. You start thinking, “how can I make this stop?”
In other words, you enter full on survival mode.
And that’s one of the best things you can do for your body.
Why? Because your body floods with chemicals to make sure you survive.
Dopamine levels soar. That’s the chemical that makes you pursue goals, like getting out of the shower alive.
Adrenaline surges through your body. That’s the chemical that makes you want to move and scream and focus and escape.
Your body starts torching calories. That’s so it can maintain a stable body temperature.
And those chemicals and processes persist once you turn off the water. That fight-or-flight response gets replaced by a profound sense of calm focus that can last for hours.³
That’s not counting the mental toughness benefit. Every time you step into that stream of cold water, you’re training yourself to endure something unpleasant. You strengthen your ability to overcome fear and to do hard, yet beneficial, things.
There are some critical factors to consider…
Don’t take cold showers too often.
Eventually, you’ll get used to shock and minimize the benefits. According to Andrew Huberman, a Stanford professor, you should aim for 11 minutes in cold water per week.²
Don’t expose yourself to dangerous situations.
Don’t take cold showers if you’re trying to build muscle.
