Is a Cold Shower the Same as a Cold Plunge? Do They Both Work?

The world of wellness is filled with a variety of practices designed to improve our health and wellbeing. Among these, cold showers and cold plunges have gained popularity for their purported benefits. But are these two practices the same? And do they both work? In this comprehensive guide, we delve into the science behind these practices, their benefits, and how they differ.

Understanding Cold Showers and Cold Plunges

What is a Cold Shower?

A cold shower, as the name suggests, involves bathing in cold water. This practice is often recommended as a way to wake up in the morning, boost mood, and improve health. The temperature of a cold shower can vary, but it's generally considered to be around 20 degrees Celsius (68 degrees Fahrenheit) or lower.

While the thought of stepping into a cold shower might be daunting for some, proponents argue that the benefits are worth the initial discomfort. But what does the science say? Let's explore.

What is a Cold Plunge?

A cold plunge, also known as cold water immersion or ice bath, involves immersing the body in cold water, typically at temperatures below 15 degrees Celsius (59 degrees Fahrenheit). This practice is popular among athletes for recovery after intense workouts.

Unlike a cold shower, a cold plunge exposes more of your body to cold water for a longer period. This increased exposure can have different effects on the body, which we'll discuss in the following sections.

Benefits of Cold Showers and Cold Plunges

Improved Circulation

Both cold showers and cold plunges can help improve circulation. When your body is exposed to cold temperatures, your blood vessels constrict, which increases your blood pressure and forces your heart to pump harder. This can help improve your cardiovascular health.

Research supports this claim. A study published in the Journal of Physiology found that regular cold water immersion can improve vascular function, reducing the risk of cardiovascular diseases.

Boosted Mood and Reduced Stress

Exposure to cold water can also boost your mood and reduce stress. This is because cold water triggers the release of endorphins, the body's natural painkillers and mood elevators.

A study published in the Medical Hypotheses journal found that cold showers can act as an effective treatment for depression, thanks to the mood-boosting effects of endorphin release.

Enhanced Recovery After Exercise

For athletes, cold plunges are often used to speed up recovery after intense workouts. The cold water helps reduce inflammation and muscle soreness, allowing for quicker recovery.

A systematic review published in the Journal of Strength and Conditioning Research found that cold water immersion can effectively reduce muscle soreness after exercise.

Comparing Cold Showers and Cold Plunges

While both cold showers and cold plunges offer similar benefits, there are key differences between the two practices. Here's a comparison:

  • Duration: Cold showers are typically shorter, lasting around 5 to 10 minutes. Cold plunges, on the other hand, can last up to 20 minutes.
  • Intensity: Cold plunges are generally more intense due to the lower temperatures and full-body immersion.
  • Accessibility: Cold showers are more accessible as they can be done at home with no special equipment. Cold plunges require a tub or pool and a way to cool the water.

It's important to note that everyone's body reacts differently to cold exposure. Some people may find cold showers more beneficial, while others may prefer cold plunges. It's also crucial to consult with a healthcare professional before starting any new health practice, especially if you have underlying health conditions.


Both cold showers and cold plunges offer a range of health benefits, from improved circulation and mood to enhanced recovery after exercise. However, they are not the same practice and each comes with its own set of considerations.

As with any wellness practice, it's important to listen to your body and consult with a healthcare professional. Remember, what works for one person may not work for another. So, explore these practices with an open mind and find what works best for you.
