Reasons to You Should Be Doing Cold Water Immersion

Cold water immersion helps activate your body's natural healing ability, which relieves the symptoms of various medical conditions, like inflammation, as it reduces muscle soreness—providing fast recovery.

If you’re curious as to why you should purchase your own cold plunge tub and what the effects of hydrotherapy are, let's discuss why you should partake in cold water immersion

1. Improves Your Lymphatic System The lymphatic system is composed of vessels that run throughout your body. It helps flush away bacteria, microbes, and wastes from your cells, thus cleansing your body.

2. Improves Your Blood Circulation Cold Water Immersion stimulates your body's blood flow into your vital organs, letting your heart pump efficiently which results in a better blood supply in your system, giving it the nutrients and oxygen it needs.

3. Reduces Muscle Inflammation High-intensity workouts and other activities may cause muscle soreness and inflammation, which can be painful and uncomfortable. CWI, on the other hand, reduces swelling, cramps, and arthritis—numbing your nerve endings to bring immediate pain relief.

Essential Factors to Consider on Cold Water Immersion

To learn more about how to start getting the benefits of cold water immersion, here are some essential factors to consider:

1. Setting the coldness to your liking You can always set the water temperature you're comfortable with to help you gain consistency and get an improved response to cold water.

You can also make the water colder as you progress on your regular routine.

2. 30 days of cold showers It is highly recommended that you start doing a 30-day cold shower before investing in a cold plunge tub, this will help you determine your body's physiological responses to an ice bath and how to manage it.

3. Purchasing your first cold plunge tub It is crucial to get the right cold plunge tub for your regular cold water immersions routine. To get the best recommendations, you may contact our team at Renu Therapy and discuss which tank is best for your immersions in cold water needs.

4. Preparing your mind and body Calming your nervous system is crucial prior to cold water immersion. Doing breathing exercises or humming can help activate your body's parasympathetic system and boosts nitric oxide production—resulting in your cells becoming more receptive to oxygen.

Is cold water good for your immune system?

There are some studies that prove cold water can increase the body's ability to fight off illnesses and muscle damage. This stems from the ability of incredibly cold water temperatures to speed up the body's production of white blood cells (WBC), the sickness-fighting leukocytes of the body.

Whether the increased WBC production is due to faster metabolism or optimized lymphatic function is still uncertain.

Some believe that exposure to low water temperatures boosts one's metabolic rate which consequently, accelerates one's immune response. With the body metabolizing faster, it also produces WBCs at a faster rate, thereby protecting it against infections more effectively, resulting in better immune function.

Meanwhile, there are those who believe that immersion in cold water causes lymph vessels to contract as the body cools down, thereby forcing the lymphatic system to pump lymph fluids throughout your body more efficiently, effectively flushing out wastes.

This process then triggers the body's immune system to release WBCs to attack and destroy the unwanted substances in the lymph fluid.

Whether the body is more efficient at fighting off illnesses due to faster metabolism or improved lymphatic drainage, CWI is proven to have some effect on a person's natural disease-fighting mechanism, resulting in enhanced well-being.

How Do You Immerse Yourself in Cold Water?

There are several ways of doing CWI. You can swim in open waters, take an ice bath in a tub, or take a cold plunge in a cold plunge tub or pool.

Whatever method you choose, make sure to follow these basic guidelines:

1. Get checked by your doctor or health practitioner before trying anything new, like cold water therapy or a CWI.

2. Know the 4 phases of CWI and know the difference between safe and life-threatening CWI.

3. Practice CWI regularly in short sessions of no longer than 10 minutes at a time, making this a habit. It is best to consult your doctor for the safest max time for your body. If you want to do it more often, slowly build up your endurance to cold water.

4. Always have someone around to help you track your blood pressure and body temperature; this is incredibly important to avoid accidentally becoming hypothermic or entering cardiac arrest from cold stress.

Is a Cold Water Plunge Good For You?

No one can tell you whether something is good for you without thorough knowledge of your health situation. Each person is unique, hence it's vital that you follow the steps outlined above and always consult your doctor before you consider CWI and introducing your body to cold exposure.

Although CWI has been studied and shown to produce great health benefits and improved well-being, it should be practiced with care—so educating yourself about immersions in cold water and body temperature are key factors.

Remember that if you do CWI wrong, you won't reap health benefits. You will be wasting time and you might even suffer permanent and possibly, life-threatening consequences. However, if practiced correctly, CWI can help you reach your peak physically, mentally, and even emotionally.
