Cold Water Immersion - Benefits and Uses of Cold Bath Tubs

Are sore muscles 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 experience these any longer. The newest trend in health and wellness helps solve all these problems and more. From easing muscle soreness to strengthening the mind, cold water immersion can do it all!

What is Cold Water Immersion?

Centuries later, science would confirm that indeed, there are many benefits of cold water immersion therapy, especially if we regularly immerse our bodies in it for short periods of time. In the last decade, studies have been coming out with more and more benefits of CWI.

Consequently, CWI is gaining more and more advocates from athletes and people with physical ailments to entrepreneurs and professionals alike.

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.

Let's briefly discuss reasons you should be doing cold water immersion and purchase your own cold plunge tub.

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 and numbs 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 temperature you're comfortable with to help you gain consistency. 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 use. To get the best recommendations, you may contact our team at Renu Therapy and discuss which tank is best for your 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. This stems from the ability of an incredibly cold environment to speed up the body's production of white blood cells, the sickness-fighting leukocytes of the body.

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

Some believe that exposure to low temperature boosts one's metabolic rate which consequently, accelerates one's immune response. With the body metabolizing faster, it also produces white blood cells at a faster rate, thereby protecting it against infections and diseases more effectively.

Meanwhile, there are those who believe that immersion in cold water causes lymph vessels to contract, 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 white blood cells to attack and destroy the unwanted substances in the lymph fluid.

Whether the body is more efficient at fighting off diseases and infections due to faster metabolism or improved lymphatic drainage, CWI is proven to have some effect on a person's natural disease-fighting mechanism.

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 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. 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.

Is a Cold Water Plunge Good For You?

No one can tell you whether something is going to be good for you without a 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.

Although CWI has been studied and shown to produce great health benefits, it should be practiced with care so educating yourself is key.

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.
