Cold water immersion | CWI

CWI, more commonly known as ice bathing or cryotherapy, is a practice that has been growing in popularity for its purported health and recovery benefits. The concept is simple: immerse yourself in ice-cold water for a certain amount of time, typically between 10 to 20 minutes, to trigger various physiological responses in your body. However, the effects are far from simple and have been the subject of extensive scientific investigation.

When you first enter the icy bath, your body responds with a sharp intake of breath – this is your body’s immediate reaction to the sudden and severe cold. This shock response stimulates the sympathetic nervous system, leading to a rush of adrenaline, increased heart rate and blood pressure. But don’t be alarmed – this isn’t necessarily detrimental. It’s your body going into survival mode, protecting its core temperature by diverting blood flow away from your extremities and towards your vital organs. This vasoconstriction process also helps reduce inflammation and swelling, particularly useful for athletes following strenuous workouts.

However, cold water therapy isn’t just for those with a love of sport. Many health enthusiasts swear by it for its potential to boost mental wellbeing and resilience. The practice is said to enhance mood, reduce stress, and improve sleep by impacting neurotransmitter production, particularly dopamine and serotonin. The initial discomfort and challenge of stepping into a freezing bath also provides a daily opportunity to face discomfort and develop mental fortitude.

Cold water therapy may also play a role in weight management. It’s believed to stimulate the production of brown fat – a type of fat that burns energy to generate heat, potentially aiding in weight loss. The body also expends more energy to maintain its core temperature in cold environments, meaning you burn more calories during the immersion.

However, the practice of cold water therapy is not without risks. The initial shock can cause shortness of breath and rapid heart rate, which could be dangerous for those with certain health conditions. Long-term, regular exposure to cold water can also impact the body’s immune response and cause hypothermia if not appropriately monitored.

In conclusion, while cold water therapy or ice baths can offer a range of benefits from recovery to mental resilience, it’s critical to approach the practice responsibly. It’s recommended to start gradually, acclimatise your body to the cold, and always listen to your body’s signals. It’s equally important to consult a healthcare professional before starting any new health regimen, especially if you have underlying health conditions. With these precautions in mind, you may find cold water therapy a stimulating and beneficial addition to your wellness routine.

Ice bath

Ice baths, also known as CWI therapy, are a form of cryotherapy that involve immersing the body, often up to the neck, in ice-cold water for a certain period of time. The practice dates back to the Roman times and has been utilised by athletes and fitness enthusiasts over the centuries. In modern times, ice baths have surged in popularity as part of a post-exercise recovery routine and a broader wellness strategy.

An ice bath typically involves filling a bathtub or a large container with cold water, then adding enough ice to significantly lower the temperature. Ideally, the water temperature should be between 10 to 15 degrees Celsius, although some individuals might prefer temperatures as low as 7 degrees. The immersion time can vary based on individual tolerance and objectives, but it generally ranges from 10 to 20 minutes.

The basic premise behind ice baths is the physiological response they elicit. When you immerse your body in icy water, it undergoes a process called vasoconstriction, where blood vessels constrict to conserve heat and protect the internal organs. Once you exit the bath and your body warms up, your blood vessels dilate, a process known as vasodilation, promoting increased blood flow throughout the body. This alternation between vasoconstriction and vasodilation can aid in flushing out metabolic waste from the muscles and reducing inflammation and swelling, thereby helping speed up recovery.

Moreover, ice baths are increasingly celebrated for their potential mental health benefits. The practice has been associated with improved mood and increased mental toughness, primarily due to the discipline and resilience required to withstand the initial shock and discomfort of the icy water.

However, it’s important to understand that ice baths aren’t suitable for everyone, and they come with potential risks. For individuals with certain health conditions, the shock of the cold could exacerbate their symptoms or trigger complications. Also, overexposure to cold water can potentially lead to hypothermia. Therefore, it’s crucial to seek professional medical advice before incorporating ice baths into your wellness routine, particularly if you have underlying health conditions.

All in all, ice baths are a compelling practice at the intersection of physical recovery, mental resilience, and personal challenge. Like any tool, their effectiveness ultimately depends on correct and mindful usage, keeping in mind individual health status, tolerance, and needs.

Cold water therapy, or the use of ice baths, can indeed offer several benefits, but it’s essential to be aware of the potential risks that come with the practice. Not everyone reacts the same way to cold exposure, and some individuals may be more susceptible to these risks than others. Here are the key risks associated with CWI:

  1. Hypothermia: One of the most severe risks of cold water therapy is hypothermia, a condition where your body loses heat faster than it can produce, causing a dangerously low body temperature. Signs of hypothermia include intense shivering, loss of coordination, slurred speech, and in extreme cases, loss of consciousness.

  2. Cold Shock Response: Upon sudden exposure to cold water temperature, one can go into a ‘cold shock response’. This is characterised by an involuntary gasping for air, hyperventilation, and increased heart rate and blood pressure. For individuals with cardiovascular conditions, this can potentially lead to heart attacks or strokes.

  3. Immersion Diuresis: This is a reaction to CWI where the body increases urine production, which can lead to dehydration if not properly managed.

  4. Reduced Immune Function: While research in this area is ongoing, some studies suggest that frequent cold therapy could potentially impact the immune system over time, increasing susceptibility to illness.

  5. Frostbite and Cold Injuries: Prolonged exposure to extremely cold water can cause frostbite, a condition that freezes your skin and underlying tissues. Other cold injuries like chilblains and trench foot are also risks.

  6. After-drop: After-drop is a phenomenon where your core body temperature continues to drop after exiting the cold water due to colder peripheral blood returning to the core. This can lead to prolonged hypothermia.

  7. Impaired Judgement or Panic: The initial shock of cold water can cause panic and disorientation in some individuals, potentially leading to dangerous situations, especially in natural bodies of water.

  8. Muscle Cramps: The cold can cause your muscles to cramp up, which can be particularly problematic if you’re immersed in deep water.

  9. Allergic Reactions: While rare, some people may experience cold urticaria, a skin reaction to cold causing itchy hives.

  10. Aggravation of Existing Conditions: ICe baths may/ can worsen symptoms of certain conditions like Raynaud’s disease, arthritis, and other circulatory or respiratory issues.

Before starting any cold water immersion or ice bath routine, it is essential to seek advice from a healthcare professional, especially if you have pre-existing medical conditions. Always ensure safety measures are in place, and remember that cold water immersion should be approached gradually, allowing your body time to adapt to the cold.

Potential Benefits

Scientifically-Accepted Benefits:

  1. Reduced Inflammation and Muscle Soreness: Immersion in cold water helps constrict blood vessels, which can reduce inflammation and swelling. It’s a common method used by athletes for recovery after intense workout/ exercise. Professional athletes swear that it also helps build muscle by faster recovery.

  2. Improved Circulation: The alternating vasoconstriction and vasodilation process resulting from entering and exiting an ice bath promotes blood flow throughout, aiding in the removal of metabolic waste products. This lower high blood pressure

  3. Enhanced Mood: Studies have shown that cold water immersion can stimulate the production of endorphins, the body’s natural mood boosters. This could potentially lead to improvements in mood and feelings of wellbeing. Ice baths work via the central nervous system which promotes the facilitation of the parasympathetic nervous system (rest & digest).

Anecdotal Benefits:

  1. Improved Mental Fortitude: Regularly enduring the discomfort of an ice bath requires and, over time, cultivates mental strength and resilience, according to numerous personal testimonies.

  2. Increased Energy and Alertness: Many users of cold water immersion report feeling more alert and energised immediately following a session. Some people use cold shower during lunch time instead of to take an ice bath.

  3. Better Sleep: Some individuals claim that regular ice baths help them achieve better sleep, although scientific studies are currently inconclusive in this area, this is amongst the highest numbers of anecdotal reports for potential benefits.

  4. Weight Management: The theory here is that cold exposure could help promote the production of brown fat, a type of fat that burns energy to produce heat. However, it’s important to note that more extensive research is needed to substantiate this claim.

  5. Improved Skin and Hair Health: Anecdotally, some people report that regular cold water immersion has resulted in healthier, more radiant skin and hair due to the cold water’s toning and strengthening effects. Well talk about using ice baths for long term benefits!

  6. Boosted Immunity: Some individuals suggest that regular ice baths help enhance their immune system and decrease the frequency of colds and other minor illnesses. However, the scientific evidence to support this claim is mixed and requires further investigation.

It’s important to remember that individual responses to cold water immersion can vary greatly, and what works well for one person might not necessarily be beneficial or safe for another. Always consult with a healthcare professional before beginning a new health regimen like ice baths.


When considering an ice bath or cold water immersion, there are several tips that can help ensure a safe and effective experience:

  1. Seek Medical Advice: Before you begin any new health or wellness regimen, consult with a healthcare provider, especially if you have underlying medical conditions.

  2. Start Gradually: Your first few immersions shouldn’t be in extreme cold, nor should they be lengthy. Start with a shorter duration and a less intense temperature, then gradually increase both as your body adapts.

  3. Use a Thermometer: To avoid guessing the temperature, use a thermometer. Aim for 10 to 15 degrees Celsius for a start, and adjust according to your comfort.

  4. Hydrate: Ensure you’re well-hydrated before and after the immersion, as cold exposure can potentially lead to dehydration.

  5. Don’t Go Alone: Especially when you’re new to cold water immersion, it’s wise to have someone present. They can help in case you react unexpectedly to the cold, and provide assistance if needed.

  6. Breathing Techniques: Focus on your breath. Deep, calm breathing can help you manage the initial shock and discomfort of the cold water.

  7. Warm Up Afterwards: After coming out of the ice bath, it’s important to warm yourself back up gradually. Wrap yourself in warm clothes or blankets, and consider drinking a warm beverage.

  8. Pay Attention to Your Body: If you feel unwell or its is signalling you to get out, don’t ignore these signs. Safety should always be the first priority.

  9. No Intense Exercise Beforehand: While cold water immersion can be great post-exercise, it’s advised not to engage in intense exercise immediately before a session, as the body is already under stress.

  10. Dry Yourself Immediately: After you exit the bath, make sure to dry yourself thoroughly to prevent further heat loss.

  11. Avoid Full Immersion Initially: It can be helpful to only partially immerse your body in the beginning, rather than jumping straight into full immersion. This might mean starting with just your legs or up to the waist.
