A Deep Dive Into Ice Baths, Infrared Saunas & Recovery

A blog post explaining Contrast Therapy and Recovery at Reconnect Chiropractic.

In recent years, contrast therapy has gained significant attention in the wellness and recovery community. This therapeutic approach, which alternates between hot and cold treatments, is increasingly popular among athletes, fitness enthusiasts, and individuals seeking holistic recovery methods. But what exactly is contrast therapy, and what does the science say about its benefits? In this blog, we'll explore the research behind contrast therapy, its benefits, and insights from experts in the field.

WHAT IS CONTRAST THERAPY?

Contrast therapy, also known as hot and cold immersion therapy, involves alternating between hot and cold treatments to promote recovery and enhance physical performance. Typically, this involves immersing oneself in hot water (like a sauna or hot tub) followed by cold water (such as an ice bath). The process is repeated several times, often in cycles of a few minutes each.

This process reduces stress through various mechanisms. Physiologically, it improves circulation and reduces inflammation, alleviating physical stress. Hormonally, it boosts endorphin levels and regulates cortisol, enhancing mood and reducing anxiety. It balances the autonomic nervous system and improves vagal tone, promoting relaxation. Psychologically, the intense sensations foster mindfulness and build mental resilience. Additionally, contrast therapy aids muscle recovery and improves sleep quality, both of which are vital for managing stress effectively.

WHAT IS AN INFRARED SAUNA? HOW DOES IT DIFFER TO A TRADITIONAL SAUNA? 

Infrared saunas use infrared heaters to emit infrared light, which is then absorbed by the body’s surface, promoting a deep, detoxifying sweat. This heat penetrates the body, raising the core temperature. Traditional saunas heat the air around you, while infrared saunas directly heat your body using infrared rays. Infrared light is a part of the non-visible light spectrum, but is experienced as heat by humans. There are many benefits to infrared light, which will be covered later.

WHAT IS AN ICE BATH?

As the name suggests, it is a bath or other similar vessel that is filled with ice and cold water, usually below 10 degrees in temperature. The concept is to get into the ice bath up to your shoulders/neck and stay there for a period of time. This cold exposure will create lots of physiological changes in your body, leading to many health benefits.

WHAT ARE THE HEALTH BENEFITS OF INFRARED SAUNA?

Infrared saunas offer several health benefits, including:

• Detoxification: Infrared saunas can help the body to eliminate toxins through sweating, promoting detoxification and cleansing.

• Pain Relief: Infrared heat penetrates tissues, muscles, and joints, providing relief from various types of pain, such as muscle soreness and arthritis.

• Improved Circulation: The heat from infrared saunas promotes better blood circulation, which can enhance cardiovascular health and oxygenate tissues. This is because our bodies dilate or expand the blood vessels close to the skin when we are in hot environments, to allow us to release more heat from our bodies. This means that once the blood vessels have dilated, more blood is circulating to the tissues around the vessels that may not usually receive as much circulating blood.

• Relaxation and Stress Reduction: Infrared saunas induce a state of relaxation by promoting the release of endorphins and reducing stress hormones, contributing to improved mental well-being.

• Skin Health: Increased blood flow can enhance skin health, leading to a clearer complexion and improved skin tone. Sweating can also help unclog pores and improve overall skin appearance.

• Weight Loss Support: While not a substitute for a healthy diet and exercise, infrared saunas may aid in weight loss by increasing heart rate and calorie burning during a session.

• Immune System Support: There is some evidence to suggest regular use of infrared saunas may help strengthen the immune system, potentially reducing the frequency of illness.

• Improved Sleep: The relaxation induced by infrared saunas, along with the potential reduction in stress, may contribute to better sleep quality. 

WHAT ARE THE HEALTH BENEFITS OF ICE BATHS?

Ice baths, also known as cold water immersion, provide various health benefits, including:

• Reduced Muscle Soreness: Ice baths help alleviate muscle soreness and inflammation, making them popular among athletes for post-exercise recovery.

• Faster Muscle Recovery: Cold exposure can constrict blood vessels, reducing swelling and flushing out waste products, thereby promoting quicker recovery after intense physical activity.

• Pain Relief: Cold temperatures can temporarily numb nerve endings, offering relief from pain and discomfort, especially in conditions like arthritis.

• Improved Circulation: Alternating between cold and warm water can stimulate blood circulation, enhancing cardiovascular health and promoting efficient oxygen delivery to tissues.

• Decreased Inflammation: Cold exposure may help reduce inflammation by constricting blood vessels and limiting the release of inflammatory substances.

• Enhanced Athletic Performance: Regular use of ice baths may contribute to better athletic performance by minimising fatigue and promoting optimal muscle function.

• Mood Improvement: Cold exposure triggers the release of endorphins, which can enhance mood and reduce symptoms of stress and anxiety.

• Immune System Boost: Cold exposure may stimulate the immune system, potentially improving resilience to illnesses.

 WHAT ARE THE HEALTH BENEFITS OF CONTRAST THERAPY?

Cold and hot therapy, also known as contrast therapy, involve alternating between cold and hot treatments to provide various health benefits, including:

• Pain Relief: Cold therapy (cryotherapy) can reduce inflammation and numb nerve endings, offering relief from pain. Heat therapy (thermotherapy) relaxes muscles and improves blood flow, reducing muscle spasms and discomfort.

• Muscle Recovery: Alternating between cold and hot treatments can aid in muscle recovery after exercise by reducing muscle soreness, inflammation, and promoting blood circulation.

• Injury Rehabilitation: Cold therapy helps control swelling and inflammation in the early stages of an injury, while heat therapy can enhance flexibility and promote healing in later stages.

• Improved Circulation: Hot therapy dilates blood vessels, promoting better blood circulation, while cold therapy constricts blood vessels, helping to reduce swelling. The combination can improve overall circulatory health.

• Joint Health: Hot therapy can alleviate stiffness and increase joint flexibility, while cold therapy can be beneficial for managing joint pain and inflammation.

• Enhanced Range of Motion: The contrast between cold and hot temperatures can help improve joint flexibility and range of motion.

• Stress Reduction: Both cold and hot therapies can induce a state of relaxation, helping to alleviate stress and tension.

• Mood Improvement: Heat therapy, in particular, can stimulate the release of endorphins, contributing to an improved mood and a sense of well-being.

• Improved Sleep: The relaxation induced by infrared saunas, along with the potential reduction in stress, may contribute to better sleep quality.

EXPERT INSIGHTS

Dr. Monique Andrews, a renowned chiropractor and neuroscience educator, emphasises the importance of incorporating holistic recovery practices like contrast therapy into a wellness routine. She notes, "Contrast therapy not only aids in physical recovery but also has profound effects on the nervous system. The alternating temperatures can help to reset the body’s stress response, promoting relaxation and mental clarity."

Athletes, too, have long sung the praises of contrast therapy. Renowned ultramarathon runner and endurance athlete, Timothy Olson, once said, "After a gruelling race or long training session, nothing helps me recover faster than a session of contrast therapy. It’s like a reset button for my body."

HOW OFTEN SHOULD I DO IT? 

1-2 times a week as a maximum. It is designed to be a shock and reset to the body - utilising cold or hot therapy more frequently reduces the benefits. At Reconnect we believe that contrast therapy depends on several factors, including an individuals health, fitness level, and specific recovery needs and should be done in consultation with Dr. Xanthe.

We recommend these time frames for optimal health outcomes when utilising our recovery services:

• 20-40 minutes infrared sauna

• 5-10 minutes to recover body temperature naturally

• 4-6 minutes in the ice bath

HOW TO INCORPORATE CONTRAST THERAPY

Incorporating contrast therapy into your routine is relatively simple. Here’s a basic guide:

1. Start with Heat: Begin with 3-4 minutes in a hot environment, such as a sauna or hot tub. This will help relax your muscles and increase blood flow.

2. Switch to Cold: Immediately after the heat exposure, switch to cold water immersion for 1-2 minutes. An ice bath or cold shower works well for this.

3. Repeat the Cycle: Repeat the hot-cold cycle 3-4 times, ending with cold immersion to reduce inflammation and cool down the body.

4. Listen to Your Body: While contrast therapy can be highly beneficial, it’s important to listen to your body and adjust the duration and intensity based on your comfort level.

THE REST IS JUST AS IMPORTANT AS THE WORK

Recovery is an incredibly important part of our lives as we navigate modern society. This is as a result of increased working demands, increasingly artificial environments we find ourselves in and the resistance towards sitting out in nature and doing literally nothing. If you observe any other animal, but particularly reptiles, lions and apes, they all have extended periods of time in their day sitting in nature not doing a single thing. This is because it is vital for healing. Our bodies use that time to soak up the benefits of our natural surroundings and begin cellular repair.

"Recovery is an incredibly important part of our lives as we navigate modern society. This is as a result of increased working demands, increasingly artificial environments we find ourselves in and the resistance towards sitting out in nature and doing literally nothing"

Using cold and heat therapy is an effective and time efficient alternative to help stimulate these healing processes in your body. Our physiology and neurology is designed to mostly be in "rest and digest" mode majority of the time. This is best achieved when not only sleeping, but also recovering and simply resting. The benefits listed earlier are all examples of the bodily processes that occur when we are in our "rest and digest" physiology.

The Science Behind Contrast Therapy

Several studies have investigated the effects of contrast therapy, particularly in the context of athletic recovery. Research suggests that contrast therapy may help reduce muscle soreness, improve recovery time, and enhance overall physical performance.

1. Reduction in Muscle Soreness: A study published in the Journal of Athletic Training found that contrast therapy was effective in reducing delayed onset muscle soreness (DOMS) compared to passive recovery. The alternating hot and cold treatments are believed to help reduce inflammation and improve blood flow, aiding in faster recovery.

2. Improved Circulation: Another key benefit of contrast therapy is its impact on circulation. The rapid shifts between hot and cold temperatures cause the blood vessels to alternately dilate and constrict, which can enhance blood flow and oxygen delivery to tissues. This improved circulation helps flush out toxins and metabolic waste, speeding up the recovery process.

3. Enhanced Immune Function: Some studies suggest that contrast therapy may boost the immune system by stimulating the production of white blood cells. The repeated exposure to cold water, in particular, has been shown to activate the body’s immune response, potentially reducing the risk of illness.
