Long before celebrity endorsements from the likes of Joe Rogan, and the popularization of the cold plunge by Wim Hof, who’s moniker the “Ice Man” made him a poster boy for the benefits of cold water therapy, cold water immersion existed for centuries in cultures around the globe.
Evidence of cold water immersion as a form of mental and physiological therapy can be traced as far back as ancient Egypt circa 3,500 BC. Later on, the Greek physician Hippocrates believed it to be a cure-all and 18th century medical practitioners as far north as Scotland sang its praises. It’s continued to be a cool topic in the world of medicine all throughout the 1900s until present day. And now the cold plunge is hotter than ever (so much so the most popular cold immersion brand is called Plunge and it's everywhere right now).
For many, cold water swimming and voluntarily plunging into an ice bath hardly sounds appealing. So where did the longstanding fascination with such a seemingly simple and brutal activity like cold therapy come from? Before it entered our modern-day wellness lexicon, cold exposure was used to treat sickness and disease, reduce stress, and more recently, enhance performance. But maybe the real stickiness is in the powerful rush of beta-endorphins that bathe the brain post-plunge, that when combined with the impressive amount of willpower one must summon to take a cold dip, leaves us with a satisfying sense of accomplishment not easily found in our comfy, climate-controlled lives.
Like enjoying an outdoor sauna or soaking in a wood fired hot tub, the cold plunge is a #selfcare ritual that seems to resonate now more than ever because it grounds us in the natural world while providing a respite from digital demands. Interested in taking the plunge into cold water therapy and maybe even buying your own cold plunge pool? You’ve come to the right place.
Read on below for a research-driven overview of this chilly activity, answers to key FAQs, and of course, a trustworthy list of the best ice bath and cold plunge tubs for at-home dips.

What is a cold plunge?
To put the method of cold water immersion into practice, start by filling a cold plunge tub with clean, filtered water that is anywhere from 50-59 degrees Fahrenheit. If you don’t own a tub that automatically cools the water temperature, an easy—and no frills—at-home solution is to add ice cubes. Once it’s cold enough, submerge your body in the cold plunge tub up to your neck, eventually submerging the entire head. Experts recommend no longer than 10-15 minutes; aim for 1-5 minutes if you're a beginner. A great rule of thumb is to just listen to your body and get out when you’re ready!
Cold baths can be done on their own, or as part of a sauna circuit, during which you warm the body in a hot sauna for 10-15 minutes, rest at room temp for five minutes, take an ice bath, rest again for five minutes, and repeat as many times as you like.
For some, cold water immersion also looks like dipping into a frozen lake, pond, or ocean for some cold water swimming. Popular iterations on the cold plunge can be found in the form of New Year’s Day polar plunge events and member swim clubs around the world.

Are there health benefits of a cold plunge?
This is a tough one. In truth, there isn’t a definitive answer to the question of whether or not cryotherapy (the application of cold for therapeutic purposes; which includes cold water immersion, among others) is the cure-all many claim it to be. Yet there is a wide range of scientific evidence and personal anecdotes that back up plunging as a legitimate tool to improve your overall health. Consider this your disclaimer.
The physical benefits and effects of cold plunging
Despite some research that suggests it might not be true, the majority of medical professionals and experts agree that cold water therapy supplements muscle recovery post-workout by offering pain relief related to muscle soreness and decreasing inflammation in the body as blood vessels constrict in cold water.
A cold plunge also alters the blood flow by temporarily redirecting circulation to the organs and away from the body’s peripherals. Evidence has shown that this improves circulation to deeper muscles and tissues (a good thing), improves metabolism and lowers the levels of the possibly detrimental stress hormone, cortisol (also a good thing), but can raise blood pressure and heart rate, which is not helpful to those with poor cardiovascular health. Sorry folks, we’ve yet to find definitive proof of the cold plunge as a miracle immune system booster or weight loss tool.
On that note, it is important to play it safe when viewing the cold plunge as a component of healthcare—especially if you are planning to submerge your entire head or expose your face to cold water. Although rare, it is possible to experience a negative shock to the system if cold water exposure triggers a heart arrhythmia that causes the heart rate to slow rather than speed up. If you have cardiovascular issues, it’s not recommended to do a cold plunge. In general, it's always a good idea to cold plunge with a buddy and take things slow!

Mental benefits and effects of cold plunging
Do cold plunges improve your mental health? The most notable effects occur immediately after a cold plunge when exposure to the cold temperatures release the beta-endorphin hormone which has a powerful effect on the brain and body. Similar to a “runner’s high”, it is associated with regulating the stress response, blocking pain receptors, and may influence dopamine levels (the brain’s feel-good hormone), which can very well boost your mood and leave you with a tranquil feeling of calm.
The shock of submerging in cold water also triggers a rush of noradrenaline in the body and brain in tandem with the beta-endorphins. When released, you experience a sudden burst of energy and sense of alertness that absolutely makes you feel alive and ready for action. There is a promising study that showed a reduction in depressive symptoms and an improvement in mood and anxiety through cold showers and cold water immersion, but it’s certainly no miracle drug. The Wim Hof method is famous for incorporating a specific way of breathing to calm the nervous system and focus the mind to make tolerating the discomfort of a cold plunge easier, and there is plenty of evidence that shows what a positive impact breathing and meditation can have on the mind-body system.
So, the bottom line is that cold plunging is not a singular solution to mental and physiological health problems. It can absolutely complement a healthy lifestyle and even enhance certain aspects of your life that contribute to feeling happier and more fit overall, yet there’s a lot more research to be done to prove that point. What is true are the undeniable health benefits of spending time outside and the intrinsic value of seeking out healthy stressors that make our body-mind more resilient and positioned for growth.

Cold Plunge FAQs
How Much Do Cold Plunge Tubs Cost?
Cold plunge tubs can cost as much as $19,000 (the most expensive pick on our list) and upwards, and they might cost as little as as $200 if you opt for a DIY method of using a stock tank purchased at a hardware store. Most made-to-plunge models are around $1,500-$5000.
Does a Cold Plunge Have the Same Effects as a Cold Shower?
Yes and no. Most showers will drop to between 50-60 degrees Fahrenheit at the coldest. Cold plunge tubs can get down to 32, depending on the model. While the purported benefits are similar, cold plunges are more immersive, and often more conducive to experiencing the mental benefits, if that's what you're after.
What Should the Water Temperature Be for a Cold Plunge?
Water temperature should be 59 degrees Fahrenheit or below. A generally accepted range is 50-59 degrees Fahrenheit, but some cold plunge tubs provide a wide range or temperatures to plunge in, down to 32 degrees.
Should I Consult with My Doctor Before Cold Plunging?
Most medical experts say yes. A negative shock to the system is possible if cold water exposure triggers a heart arrhythmia that causes the heart rate to slow. If you have cardiovascular issues, it’s not recommended to do a cold plunge. You should also consider plunging with a buddy, especially when plunging outdoors in natural bodies of water, and take it slow if you're a beginner.
Do Cold Plunge Tubs Burn Fat?
That cold plunging for weight loss is a popular claim on social media, there is no confirmed scientific evidence that it actually works.
