Contrast Therapy
Also known as Viking baths or hot-cold therapy, is a form of treatment that involves alternating exposure to hot and cold temperatures to promote various health benefits. It has been used for centuries in different cultures and is popular in Scandinavian countries, hence the name "Viking baths."
The therapy typically involves immersing or exposing the body to hot water or heat, followed by exposure to cold water or ice. The alternation between these two extremes causes blood vessels to dilate and constrict, which can lead to several positive physiological effects.
Hot Phase
During the hot phase, you are exposed to elevated temperatures in my infrared sauna.
The hot phase increases blood flow to the skin and muscles, promoting relaxation and vasodilation (widening of blood vessels).
The heat also stimulates sweat production, aiding in the elimination of toxins and waste products from the body.
Cold Phase
The cold phase involves exposure to cold through the form of an ice bath. There is no actual ice in the bath, the water is filtered and cooled to a specific temperature.
The cold temperature causes vasoconstriction, narrowing the blood vessels, and reducing blood flow to the skin's surface.
This cold-induced vasoconstriction helps to reduce inflammation and swelling, numbs nerve endings, and alleviates pain.
Alternate Cold & Hot Phases
The key component of contrast therapy is the alternation between the hot and cold phases.
​
The rapid shifts in blood flow from vasodilation to vasoconstriction and vice versa are believed to enhance circulation and create a "pumping" effect in the blood vessels, facilitating the removal of waste products and promoting nutrient delivery to tissues.
Precautions
Contrast therapy may not be suitable for everyone, especially those with cardiovascular issues, hypertension, or Raynaud's disease. It's essential to consult a healthcare professional before attempting contrast therapy.
Gradually increase the intensity of contrast between hot and cold temperatures to avoid shocking the body.
Avoid prolonged exposure to extreme temperatures to prevent burns or frostbite.
Overall, contrast therapy, or Viking baths, can offer a range of health benefits when used correctly and safely. However, it's crucial to consider individual health conditions and consult a medical professional before incorporating this therapy into your routine.

There have been several scientific studies investigating the effects of contrast therapy or hot-cold treatments. It's important to note that research in this area is ongoing, and new studies may have been published since then.
