In this article, Jason Grubb will tell you about his 30-day experiment of deliberate cold exposure, the results of that experiment, and his intentions for the future. Although it might seem a bit crazy to confront the cold, there is actually a solid scientific basis behind this practice. He decided to take on this cold exposure challenge because he discovered the many benefits of ice baths in the morning. Temperature is a powerful stimulus that can have a huge impact on our body and mind.

The benefits of exposure to cold

I previously used cold therapy occasionally after my workouts, but the more I learned about the benefits of cold exposure, the more intrigued I became. The potential benefits of cold exposure sounded impressive, so I decided to take on the challenge of cold exposure for 30 days using my ice bath, a container specially designed for this purpose.

The results and benefits observed

I'm not going to lie to you, it was extremely cold, and it still is. I'm not the type of person who walks in without showing pain, it takes my breath away every time. Every day I feel considerable internal resistance, but even if it only gives me resilience, it is enough for me. However, I have personally seen results far greater than just resilience.

First, I noticed an improvement in my mental clarity and found it easier to stay focused on my tasks throughout the day. I could get to work immediately after my ice bath and stay in my focus zone longer than before. This is likely because exposure to cold activates the sympathetic nervous system, which improves cognitive function and increases attention.

Then I saw a positive impact on my sore muscles and sore parts of my body. For example, I had been struggling with lower back pain for a few months, and after the cold exposure I saw a marked improvement. Exposure to cold can increase the production of endorphins, natural painkillers.

The biggest and most remarkable benefit I have observed is the improvement in my mental well-being. I found that exposure to cold can help reduce stress and improve my mental health. Research has shown that the endorphins I discussed earlier can improve mood, reduce stress and anxiety, and support overall well-being. I actually felt these effects throughout this process.

My research has also led me to discover other benefits of cold therapy. First, an improvement in immune function and cardiovascular endurance. Cold water immersion has been shown to increase the production of white blood cells, essential for fighting infection, and improve blood flow to muscles, thereby promoting cardiovascular endurance.

There are many other benefits associated with cold therapy, and one of my favorite resources for digging deeper into the subject is Andrew Huberman's podcast, where he discusses cold exposure. It's a two and a half hour long episode, but definitely worth a listen if you want to know more.

Answers to frequently asked questions about cold exposure

Following my social media posts regarding my ice bath experience, I received many questions about cold exposure. Here I will answer some of the most common questions:

  1. Is it safe to practice cold exposure?
    Exposure to cold can be safe if you take the necessary precautions. It is important never to venture into dangerous waters, such as a cold river where you could be swept away. In addition, it is not recommended to practice hyperventilation before a cold exposure session.

  2. What temperature should the water be for cold exposure?
    The ideal water temperature for exposure to cold varies from person to person. It is important to aim for a temperature that is really cold, but at which you can stay safe. Some people can tolerate a temperature of 15 degrees Celcius, while others prefer 7 degrees. The colder the stimulus, the less time you will need to expose yourself to it.

  3. What is the best method for exposure to cold, ice baths or cold showers?
    Ice baths and neck-deep immersion in cold water are great methods, but cold showers can also be effective if you don't have access to an ice bath.

  4. How can cold exposure increase energy and focus?
    Exposure to cold causes the release of epinephrine and norepinephrine in the brain and body, which can make you alert and increase your energy and concentration. These chemicals stay elevated for some time after exposure, providing long-lasting benefits for energy and focus.

  5. How can exposure to cold improve mood and build resilience?
    By confronting the stress of cold exposure as a meaningful challenge, you can exercise mental control over the deeper brain centers that regulate reflexive states. This builds resilience and the ability to cope with other situations apart from exposure to cold. It's a bit like diving into the "cave of pain" without having to do any extra training.

  6. How can cold exposure boost metabolism and promote weight loss?
    Exposure to cold increases the density and/or activity of so-called brown fat, which is a more metabolically active type of fat than others. Additionally, exposure to cold can also increase adrenaline production, which promotes the breakdown of fat cells.

Advice for those wishing to try cold exposure

If you're interested in cold weather exposure, here are some tips to get you started:

  1. Start by taking cold showers. Gradually decrease the water temperature over the minutes and try to stay as long as possible. Gradually increase the duration as you get used to it.

  2. Practice Wim Hof's breathing technique . This specific breathing technique prepares your body and mind for difficult situations, such as immersion in an ice bath. Look for tutorials by Wim Hof ​​on YouTube to learn this method.

  3. Invest in an ice bath or create your own ice bath vessel. The ice bath is sturdy, with a drain at the bottom and a lid, which makes it easy to use. However, you can also use plastic trash cans or other similar containers if you prefer.

  4. Keep a journal to document your experience. Write down the changes you feel, both physically and mentally. This will help you assess whether cold exposure suits your routine and personal needs.
