Are joint pain, muscle soreness or spasms keeping you from performing your best? Feeling groggy in the middle of the day? Tossing and turning at night?

These are just some of the concerns many of us suffer from. But we don't have to go through these any longer. Coldwater immersions (CWI) is the newest trend in health and wellness which help solve all these problems and more—from easing muscle damage to strengthening the mind, cold water immersion can do it all!

What is Cold Water Immersion?

It's Right For Me!

Reasons to You Should Be Doing Cold Water Immersion

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?

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.
