Introduction
Did you know that exposing your body to colder temperatures can benefit your health in numerous ways? One of the key benefits is fat loss. In this article, we'll explore six different ways cold exposure can be highly beneficial for your body.
1. Brown Fat
The first benefit is, of course, weight loss. We have different types of fat in our body; cold exposure boosts your body's brown fat, which is more thermogenically active compared to white fat. Brown fat contains more mitochondria, the energy-burning cells that help generate heat. Interestingly, white fat can transform into beige fat, which is essentially white fat that develops more mitochondria and becomes more similar to brown fat. This process helps increase fat burning. Exposing your body to cold in small, safe increments is a highly effective way to stimulate this transformation and support weight loss.
2. Increased Heat
The second benefit that I have on my list of cold exposure is that of course it helps to increase your body heat, and this is due to mitochondrial uncoupling. A study found that for the first time and this was a human study, that skeletal muscle has the intrinsic capacity for cold-induced adaptive thermogenesis. So the making of more body heat via mitochondrial uncoupling under physiological conditions, meaning being in the cold. What our mitochondria can do, is they can dissipate protons to actually create heat. We always hear about mitochondria being the energy by the Power House of the cell, of course yes that is a major function of our mitochondria. But another one is to dissipate protons; meaning creating more body heat, and of course, this is more common in people who have this adaptive capacity because their mitochondria are in fact uncoupled. These individuals, often from colder regions like Northern Europe or Northern Canada (like myself), have inherited this trait through generations, adapting to their environment.
3. Less Pain/Inflammation
If you've bruised, banged, or injured yourself, what do you do? You apply ice! While this helps with pain and inflammation, cold exposure also has broader benefits for your body. When your mitochondria become more efficient at creating a special type of water in your body—Exclusion Zone (EZ) water—it improves your internal energy production. This, in turn, enhances fluid flow through your fascia system. This process is fantastic for promoting an anti-inflammatory state throughout the body.
4. Less Anxiety
Number four is reduced anxiety. We know that cold immersion—whether it's submerging your head in an ice-cold water bucket, immersing your hands or feet, or taking a full-body ice bath—stimulates the vagus nerve. This activation helps shift your nervous system into a more relaxed state, activating the parasympathetic nervous system, which promotes calm and relaxation. When combined with proper breathing techniques, cold exposure can counterbalance the sympathetic nervous system, which is responsible for the "fight or flight" response, the survival mode of your autonomic nervous system.
5. Better Sleep
We know that the brain needs to stay cool in order to properly secrete melatonin, which is essential for a good night's sleep. Cooling your room is important, but cold exposure throughout the day also plays a role. It supports mitochondrial health and can help improve the quality of your sleep at night.
6. Improved Immunity
We know that cold plunges or cold showers help stimulate the immune system. It's not what our moms always told us—I've even been guilty of telling my kids to bundle up when it's cold outside. While it's important to protect them from prolonged exposure, short bursts of cold exposure are very beneficial and protective for the immune system. In fact, they can help prevent illness, as our bodies adapt and strengthen with this type of exposure.
