Have you ever heard of that crazy trend where you submerge your body in a tub of ice in order to help lose weight? Are you wondering if this trend really works?

According to journalist and anthropologist Scott Carney, this trend is definitely onto something extraordinary. In Carney’s book, What Doesn’t Kill Us, he investigates this phenomenon with the help of Wim Hof, who practices methods of physical transformation that combine environmental exposure, mostly in the cold. According to Hof, exposing yourself to the cold can strengthen the body and help people heal from injuries and diseases.

What Doesn’t Kill Us: Are Comfortable Temperatures Making Us Unhealthy?


In his book, What Doesn’t Kill Us, Carney talks about how Huf claims that “a method of cold immersion and conscious breathing can give people some ability to voluntarily activate or suppress their immune system.” Carney also investigated others who have dabbled in this idea of adapting to extreme weather change to the body, for instance, Lewis Pugh, an open water swimmer, and certain monks.

According to Carney, as per his investigation, “there’s promising data that suggests cold exposure plays a role in weight loss”. Although many are still skeptical about this method of body and mind strengthening, after all his investigation, Carney is definitely convinced on the idea.

So what is Carney trying to illustrate? In a nutshell, he’s trying to explain how humans were built to learn to survive in any circumstance. That being said, today, humans rely on comfort over survival; we turn up the heat when it gets too cold, we crank up the AC on those hot summer days. Carney claims that this idea of comfort over survival may not be healthy, “With no challenge to overcome, frontier to press, or threat to flee from, the humans of this millennium are overstuffed, overheated, and understimulated,” – Carney.

How Cold Temperatures Help Aid Weight Loss

With this idea in mind, let’s dive right into how extreme temperatures can help us lose weight. Scientists at the University of California-Berkeley report that they have discovered a protein that can increase the production of ‘brown fat’. There are two kinds of body fat, brown fat and white fat, brown fat helps burn its own fat, whereas white fat stores body fat. According to their study, the mice embryos were born with more brown fat due to the exposure of extreme cold weather.


So, what does this mean? Ultimately, you want more brown fat in your body because it helps you burn overall fat. So how can you achieve this? The idea is to increase the ratio of brown fat to white fat by exposing yourself to colder temperatures. For example, being outdoors in the cold air helps you burn more calories because your body is making a huge effort in keeping you warm.
