Saunas have been used for centuries for their health benefits, including relaxation, stress relief, and improved circulation. Cold water therapy, on the other hand, has been used for its pain relief and anti-inflammatory properties. Combining sauna with cold water therapy, known as a "hot sauna cold plunge" or "sauna and cold water", has become increasingly popular in recent years, and for good reason.

In this article, we will explore the benefits of sauna cold water therapy and why it may be worth incorporating into your wellness routine.

What Is Sauna Cold Water Therapy?

Sauna cold water therapy involves alternating between hot and cold temperatures, typically by spending time in a sauna or hot tub followed by a cold plunge pool, cold shower, or ice bath. The heat of the sauna causes your blood vessels to dilate, increasing blood flow and allowing your body to sweat out toxins. The cold water then causes your blood vessels to constrict, reducing inflammation and pain, and promoting faster muscle recovery.

Tip: For enthusiasts designing a wellness routine at home, integrating a luxury home sauna with a dedicated cold plunge setup creates an optimal, spa-quality hot/cold cycle for daily recovery and relaxation.

Cold water therapy, also known as cold water immersion or cold therapy, involves exposing your body to cold water for a short period of time. While this may sound uncomfortable or even painful, many people use cold water therapy as a way to improve their physical and mental health.

There are several ways that people use cold water therapy, including:

Cold showers: Taking a cold shower can be a quick and easy way to experience the benefits of cold water therapy. Simply turn the water to a cooler temperature and stand under the water for a few minutes.

Ice baths: An ice bath involves submerging your body in cold water that has been chilled with ice. This can be a more intense form of cold water therapy, as the water can be much colder than a cold shower.

Cryotherapy: Cryotherapy involves exposing your body to extremely cold air for a short period of time, typically in a special chamber that is designed for this purpose. This is a relatively new form of cold water therapy, but it has gained popularity in recent years.

Why Do People Use Cold Water Therapy?

Here are some of the potential benefits:

Reduced Inflammation: Cold water therapy has been shown to reduce inflammation in the body, helping to prevent or treat conditions like arthritis or heart disease. Pairing your session with a full-spectrum infrared sauna for sale can maximize anti-inflammatory effects, using heat to promote circulation followed by cold immersion for systemic recovery.

Improved Recovery: Cold water therapy may also help to speed up recovery after exercise by flushing out lactic acid and other metabolic waste, reducing muscle soreness and improving recovery time.

Increased Alertness: The adrenaline rush from cold exposure can improve circulation and sharpen mental focus—a benefit many combine with post-sauna routines to leave sessions feeling revitalized and clear-headed.

Reduced Stress: Exposing yourself to cold water promotes a mild shock response, triggering a reset in your nervous system and promoting feelings of calm and relaxation.

Improved Immunity: Cold water therapy can increase white blood cell production, boosting your immune response.

While cold water therapy can be beneficial, remember to:

·        Start slowly and build up exposure over time.

·        Listen to your body and stop if you feel unwell.

·        Limit sessions to a few minutes and don’t overdo it.

·        Consult your healthcare provider before starting, especially with medical conditions.

Benefits of Sauna Cold Water Therapy

Increased Circulation and Metabolism

Spending time in a sauna increases heart rate and circulation, helping deliver more oxygen and nutrients throughout your body. Cold water immersion quickly follows, flushing out waste products, reducing inflammation, and supporting rapid recovery.

Stress Relief and Relaxation

Improved Skin Health

The combination of heat and cold can help open pores during the sauna and close them in the cold plunge, flushing toxins and leaving skin bright and refreshed. Using sauna accessories like soft towels and hydration bottles can further enhance your at-home skin and wellness regimen.
