Picture yourself stepping into the shower and turning the knob to cold. A bit of a shock, perhaps? But surprisingly, cold showers and cold water immersion therapy are on the rise—and not only with hardcore athletes. Increasing numbers of people are finding that these frigid practices bring genuine health advantages, from a mood boost to assisting their muscles in recovery. It’s not just a matter of toughness; it’s a simple, science-backed way of fueling your well-being.
What Is Cold Therapy?
Cold therapy, or cryotherapy, is simply a matter of subjecting your body to cold for a health advantage. It may sound extreme, but there are a couple of simple ways to try it. You can take a cold shower, sit in an ice bath, or even experience a full-body cryotherapy session where you’re surrounded by cold vapor. For the majority of us, however, a brief cold shower is the simplest place to begin.
Experts say that cold showers are water temperatures less than 60°F (15°C) for a couple of minutes. It may give you the shivers just considering it, but once you hear about the advantages, you might be inclined to try it.
The Science-Backed Benefits of Cold Showers and Immersion Therapy
Boosting Immunity
Switching to cold water in your shower could potentially make your immune system more robust. Dutch researchers found that people who took cold showers as part of their everyday routine took fewer sick days off work. The thinking is that the cold water shock activates your immune system to cause your body to produce infection-fighting white blood cells. In a way, it may give you a little extra safeguard against common bugs.
Relieving Muscle Soreness and Inflammation
Ever seen players dunking themselves in ice baths after a high-stakes game? There’s a reason they do it. Cold water constricts your blood vessels, which helps cut down on swelling and inflammation. And then, when your body heats up again, blood comes back to your muscles, carrying fresh oxygen and nutrients to help heal faster. Studies show that even a quick soak in cold water can make a big difference in post-workout soreness.
Cyclists, for example, discovered that they were much less sore following a 10-minute cold water bath after intense training sessions.
Improving Circulation
When you are cold, your body enters “survival mode” and works hard to maintain your core temperature. This pumps your circulation as blood circulates through your large organs and muscles. With continual practice, this enhances the health of your circulatory system, something that is a boon for those who suffer from illnesses such as high blood pressure or diabetes.
Boosting Mood and Decreasing Anxiety
Cold water therapy doesn’t just benefit your body—it can also work wonders for your mind. Some studies suggest that cold showers and open-water swimming can help ease symptoms of depression and anxiety. In one case study, a woman found major relief from depression after regularly swimming in cold water.
The theory is that exposing yourself to cold triggers your sympathetic nervous system and releases endorphins—those good-feeling chemicals that improve your mood. Most people feel calmer, more energized, and less stressed after a cold plunge.
Supporting Metabolism and Weight Management
Your body expends additional calories when it’s subjected to cold temperatures in an attempt to warm itself up. A cold shower will not substitute for your usual exercise, but it may provide your metabolism with a slight kick. Cold exposure has also been thought by some experts to trigger brown fat, a form of fat that makes you burn energy more effectively.
Cooling Down Quickly After Overheating
If you’ve ever overheated after exercise or too much time in the sun, you know how difficult it can be to cool down. Cold water immersion is one of the quickest methods of returning your body temperature to normal. Studies demonstrate it’s much more effective than simply resting in a cool environment or drinking ice water.
How to Incorporate Cold Therapy Into Your Routine
If you’re interested but a bit apprehensive about jumping into cold therapy, begin slowly. Experiment with finishing your shower with a brief 30-second burst of cold water. As you become more at ease, gradually work up to longer periods.
For athletes and active individuals, a 10-minute soak in cold water following a challenging workout is a complete game-changer. Just make sure to keep it short—a little over 10 minutes is typically adequate to reap the rewards without overdoing it.
A Word of Caution
Although cold showers and immersion therapy are safe for the majority of individuals, it’s a good idea to consult with your physician first, particularly if you have any circulatory or heart problems. Cold exposure can be stressful on the body, so it’s wise to ensure that it’s the best fit for you.
If you need a mood boost, increased recovery, or simply want to mix things up, cold showers may be exactly what you need. So go ahead and try it next time you get into the shower and turn that dial to cold. It may wake up more than your senses—your entire health may get a refreshing boost.
