If you have ever wondered what happens to your body after 30 days of cold showers, one content creator has lifted the lid.
YouTuber Jeremy Ethier posted a video where he explained the science behind what happens when you spend an entire month taking daily cold showers.
In the clip, he revealed that the ‘benefits of cold showers’ which he discusses in the video, will make you ‘reconsider’ opting for a warm shower.

Ethier explained: “You’ll start experiencing the benefits of cold showers right from day 1. Exposing your body to cold seems to release 3 key hormones; norepinephrine, epinephrine, and dopamine. Together these stimulate your ‘fight or flight’ response.
“These hormones stay elevated for an extended period afterwards. Anywhere from 30 minutes to several hours depending on how cold the water was and how long you were in it. The benefit of this is improved mood, energy, and focus. But to experience these benefits, there are a few things you need to know.”
He went on to say: “First, the temperature of the water for your cold showers needs to be cold enough. Research suggests at least 60 degrees Fahrenheit or colder. To tell if it’s cold enough without a thermometer, it should trigger what’s known as the ‘initial inspiratory gasp’. But you also need to stay in the cold for long enough. The subjects in the study I mentioned earlier sat in cold water for an hour. I did find several studies showing benefits with shorter durations of even just 20 seconds of cold exposure.
“But in most cases, they used an ice bath instead of a shower. This doesn’t mean a 30 second cold shower won’t do anything though. Even if your hormonal increase isn’t significant by research standards, you will likely still feel a benefit and an increased mood. But over time, your body adapts to the cold and the hormonal response seems to die down. Once you notice this, here’s how to take a cold shower to continue feeling a benefit: try making the water colder or staying in it for longer.”
The YouTuber details how a study from 2021 found that ‘cold water immersion increased well trained athletes’ estimated daily calorie burn from 2,000 calories per day all the way up to 3,000 calories’.
Ethier added: “There’s one more benefit you should know about. Forcing yourself to mentally withstand a stressor like the cold activates an area of your brain that suppresses impulsivity. This can help you remain calm and not overreact whenever stressors come up in your life.”
