A Beginner's Guide to Cold Therapy

Cold therapy, or cryotherapy, isn't a modern-day invention. Its origins can be traced back to the Spartan warriors who braved frozen rivers to build resilience and strength, and to ancient Egyptians who used cold baths to treat injuries and inflammation. In the early 20th century, the renowned Austrian physician Vincenz Priessnitz popularised the use of cold water for healing, leading to the establishment of hydrotherapy clinics across Europe. 

Today, this age-old practice is experiencing a resurgence thanks to experts like Wim Hof, the creator of a famous breathing technique, which we already talked about in our blog, and influencers like Joe Rogan, who have popularised it through their platforms. For this reason, more and more people are rediscovering the great health benefits of cryotherapy for their physical and mental well-being.



The Science Behind Cold Therapy


  • Boosts Circulation and Reduces Inflammation

When you expose your body to cold water, your blood vessels constrict and then dilate once you return to warmer temperatures. This process, known as vasoconstriction and vasodilation, improves circulation and helps flush out toxins from your system. Good circulation leads to better cardiovascular health and a more efficient delivery of oxygen and nutrients to your muscles and organs.

Cold shower therapy also reduces inflammation by lowering the temperature of damaged tissues and constricting blood vessels. This is why athletes often use ice packs or baths to alleviate soreness and speed up recovery after intense workouts.

  • Enhances Mood and Energy Levels

Starting your day with a cold shower can be a natural energy booster. The shock of cold water triggers the release of endorphins, the body's "feel-good" hormones, leading to an immediate uplift in mood. It also stimulates the production of norepinephrine, a hormone and neurotransmitter that enhances focus, attention, and energy levels. So, instead of reaching for that extra cup of coffee, consider a refreshing cold shower to start your day.

  • Strengthens the Immune System

Regular cold exposure can have a profound impact on your immune system. Studies have shown that cold showers can increase the number of white blood cells, which play a crucial role in fighting off infections and diseases. By incorporating cold shower therapy into your routine, you might find yourself falling sick less often and feeling more resilient against seasonal illnesses.

  • Promotes Better Sleep

While it might seem counterintuitive, cold shower therapy can actually promote better sleep. Cold exposure activates the parasympathetic nervous system, which is responsible for rest and relaxation. This can help calm your mind and body, making it easier to drift off into a deep, restorative sleep. So, if you struggle with insomnia or restless nights, a quick cold shower before bed might be the solution you need.

  • Encourages Mental Resilience

Cold shower therapy is not just about physical benefits; it also challenges your mental fortitude. Getting into cold water requires a level of mental toughness and the ability to push through discomfort. Over time, this practice builds resilience and a greater tolerance for stress, helping you tackle life's challenges with a strong sense of determination.


How to Incorporate Cold Therapy into Your Routine


The beauty of cold shower therapy lies in its flexibility, because you don't need to dive headfirst into an ice bath to experience the benefits. Here are some simple ways to start incorporating cold exposure into your daily routine:

  • Start with a Cold Finish

If the idea of a full cold shower feels overwhelming, start by ending your regular shower with a burst of cold water. Begin with just 10-30 seconds and gradually increase the duration as you become more comfortable. Focus on your breathing and try to relax… you might even start to enjoy it!

  • Alternate Between Hot and Cold

For a more advanced approach, try alternating between hot and cold water during your shower. This method, known as contrast hydrotherapy, can enhance circulation and be a more intense experience. Spend 1-2 minutes in hot water, then switch to 30 seconds of cold, and repeat the cycle a few times.

  • Listen to Your Body

As with any new practice, it's important to listen to your body and move at your own pace. Cold shower therapy should be invigorating, not overwhelming. And remember, if you have any pre-existing health conditions or concerns, consult with a healthcare professional before starting a cold therapy regimen.


Advanced Options for the Brave


If you have already embraced cold showers and read all the blogs on Wim Hof’s cold exposure method out there, you can step up the game with:

  • Ice Baths

Ice baths are a popular choice among athletes and wellness enthusiasts. The key to a successful ice bath is gradual acclimatisation, which means that you should start with shorter durations and fewer ice cubes, then work your way up to longer sessions with more ice. The ideal temperature for an ice bath is around 50-59°F (10-15°C), and sessions can last anywhere from 5 to 15 minutes.

  • Visiting an Ice Lake

If you're lucky enough to live near a natural ice lake, take advantage of this incredible resource. Immersing yourself in an ice lake can provide a deeply invigorating experience and connect you with the raw power of nature. Ensure you have proper guidance and safety measures in place, as natural cold water sources can be unpredictable.


One of the greatest advantages of cold shower therapy is its adaptability. You start with a few seconds of cold water at the end of your shower or dive into an ice bath, the important thing is to find a routine that works for you. It’s easy to experiment with different methods and durations, paying attention to how your body responds.
