How cold baths improve your health

When I first heard about the benefits of cold baths and showers, I was a bit skeptical.

As an orthomolecular and Ayurvedic therapist, I often use heat as therapy: warm food, drinks, warming oils, steam baths – these are all traditional methods to bring balance to an overstimulated system.

Cold, I had always learned (do you recognize your mother's voice haunting you with: 'put on something warmer, or you'll get sick'?), brings even more stress and makes us ill.

How can something that adds cold, like a cold bath, be good for your body and mind?

Nevertheless, I decided to delve deeper into the science behind cold therapy and came to surprising insights.

Cold baths are not just an extreme trend; they have been practiced for a very long time in various cultures. And now they rightly have their place in contemporary lifestyle medicine.

Here I will explain why cold showers can genuinely be worthwhile and how you can responsibly integrate them into your daily routine.

Thermoregulation

As humans, we have always been exposed to changing weather conditions, and our bodies are naturally capable of adapting. But due to our modern lifestyle, where we spend a lot of time indoors and are almost always at a comfortable temperature thanks to central heating, our thermoregulation system has become lazy. We have become "desensitized" to cold, and that affects our resistance and energy levels.

Regular cold showers reactivate our thermoregulation system. By training the body to keep itself warm naturally, you not only strengthen your resistance to cold but also give your immune system and energy levels a significant boost. You'll notice that you are less susceptible to colds and even infections.

 

Brown fat and fat burning

Cold showers also have a remarkable effect on your fat burning.

The body has two types of fat tissue: white fat and brown fat. White fat is the excess fat the body stores for times of scarcity. Fat for harsh times.

But in our current society, with abundant food and constant warmth, that white fat is hardly used and remains stored in your body.

Brown fat, on the other hand, has a completely different function. It is active in cold and helps your body generate heat. When you regularly take cold showers, this brown fat is activated. It converts stored fat into energy to keep you warm. This process increases your metabolism and promotes fat burning, helping you lose weight naturally.

This is a powerful mechanism that was evolutionarily intended for survival in cold conditions but can now be very well used to reduce excess "fat reserves." Through cold showers, your body can finally start tapping into these fat reserves.

Strengthen your immune system

Another major benefit of cold showers is the strengthening of your immune system.

Cold stimuli cause your body to produce white blood cells, which are essential for fighting infections and viruses. This means you are better able to ward off diseases.

During my orthomolecular therapy training, I learned how energy is distributed between your metabolism, brain, and immune system. Cold showers optimize this distribution, making more energy available for your immune system. This helps to tackle unwanted invaders more effectively and reduces the chance of illness.

More energy and alertness

A cold bath wakes you up!

Your sympathetic nervous system, which is involved in the fight-or-flight response, is activated by the cold. This leads to increased blood pressure, deeper breathing, and a decrease in CO2 in your blood.

The result?

An immediate feeling of alertness and energy that you can feel all day long.

This is why many people who take cold baths say they feel sharper and more alert throughout the day. It's a natural way to wake yourself up and stay mentally sharp, without needing coffee.

Fitness for your blood vessels

Cold showers stimulate your cardiovascular system by causing the blood vessels in your body to constrict and then dilate again when you step out of the shower/bath. This process strengthens the muscles around the blood vessels, which promotes your circulation and contributes to a healthy heart.

For people without existing heart problems, cold therapy can therefore be an excellent way to proactively work on heart health. However, if you suffer from cardiovascular diseases, it is wise to consult a doctor before starting cold therapy.

Stress reduction and mental resilience

Regular exposure to cold exposes your body to controlled stress, resulting in a process called “hardening.”

This means that your nervous system becomes stronger and better able to cope with other forms of stress, both physical and mental.

By training your mind to remain calm in cold conditions, you learn to maintain your inner peace in other stressful situations as well. This is an important aspect of the Wim Hof method, where breathing and cold therapy come together to develop mental strength.

My own experience with cold baths

I've been taking cold showers since our year in Portugal, where we could only shower cold for a long time.

Last year, I bought an ice bath, and it helped me heal well from my knee injury.

I especially love the incredibly euphoric feeling after an ice bath. You will love it!

Do you want to give it a try?

Start slowly and build up, so your body and mind can adapt.

You start by rinsing off with cold water after a warm shower and gradually increase the time. At some point, you'll feel ready to start with cold water from the beginning.

Once this is a habit, you can switch to cold baths.

Cold therapy is a powerful tool to improve your health. It strengthens your immune system, promotes fat burning, increases your energy levels and alertness, and helps you cope better with stress.

Although it may feel uncomfortable at first, the reward is worth it.

Who knows, like me, you might become convinced of the power of the cold!
