Why Do Athletes Take Ice Baths?
Ice baths and Cold Water Immersion (CWI) is popular amongst athletes and well-being enthusiasts around the globe, with this practice becoming a staple in many athlete’s training regimens.
With research ongoing around routine practice, we discuss the science behind ice baths, potential benefits and drawbacks, as well as alternative options.
How Ice Baths Work
Ice baths work by constricting blood vessels to reduce blood flow, which is thought to have a range of effects on the body.
When you immerse your body in cold water, the blood vessels constrict in a process known as vasoconstriction in an attempt to reduce heat loss. Vasoconstriction reduces the amount of blood flowing to the muscles, which can help decrease inflammation and soreness in these areas, as well as aid with flushing waste products like lactic acid from affected tissue, and reducing metabolism.
It's important to note that individual responses to ice baths may vary, so consulting with a healthcare professional is recommended.
Potential Benefits of Ice Baths for Athletes
The potential benefits of an ice bath include reduced inflammation and soreness, as well as improved recovery time and circulation.
As previously touched on, ice baths cause your blood vessels to constrict, reducing inflammation by decreasing the flow of blood to the area.
Reduced blood flow can help to limit the inflammation in your muscles, which is beneficial for athletes who frequently experience muscle inflammation after intense workouts or competitions.
Ice baths can also help reduce soreness by numbing the area and decreasing inflammation caused by minute tears in the muscles. Delayed onset muscle soreness can potentially also be relieved thanks to reduced metabolism.
It is also thought that this process aids faster recovery time for athletes. However, the belief that ice baths aid faster muscle recovery through promoting quickened healing of microtrauma and tears in the muscles is contested.
Cold water immersion can increase blood flow and promote better circulation throughout your body. Increased blood flow is attributed to the cold water causing blood vessels to constrict, followed by vasodilation when the body warms up.
When to Use Ice Baths
Ice baths are commonly used immediately following intense training sessions, after competitions and during high-volume training periods. Utilising ice baths soon after exercise can enhance their effectiveness in reducing muscle soreness and inflammation, by occurring before natural healing and inflammatory responses kick in.
By incorporating ice baths into your routine during these key times, you can supplement training regimes with CWI therapy.
Recommended Ice Bath Practices
If you’re participating in an ice bath, it’s best to stick to recommended practices. If you’re unsure, consult a professional.
Optimal Water Temperature
It is recommended that water temperatures stay around 10-15°C for maximum benefits.
Maintaining the water temperature within this range ensures the best results from the ice bath. Water that is too cold can lead to discomfort and potential adverse effects, whilst water that is too warm may not provide the desired therapeutic effects.
Recommended Duration
The duration of an ice bath typically ranges from 2 to 15 minutes, depending on your comfort level and tolerance. It is advised to start with shorter sessions and gradually increase the time as you become more accustomed to the cold temperature.
Individuals with lower body mass, muscle mass, and fat mass may be more sensitive to the effects of an ice bath, so it is recommended for them to start with shorter durations.
Body Parts to Submerge
When taking an ice bath, you should immerse your entire body, leaving only your head above the water to experience the benefits of cold therapy.
Potential Risks and Precautions
Before participating in an ice bath, you should be aware of the potential risks and precautions to take.
Because we’re not yet aware of the full range of risks to taking ice baths routinely or long-term, it is recommended to build up your tolerance to cold water immersion over time. Gradually building the duration as your tolerance increases.
Cold Shock Response
When exposed to water 15°C and below, cold shock response can occur as a natural response to the change in temperature.
This is when your blood vessels constrict, making it harder for blood to flow smoothly, putting additional strain on your heart, and causing an increase in blood pressure.
Additionally, the sudden drop in temperature can lead to a change in breathing rates, potentially causing panic or hyperventilation.
Hypothermia
Hypothermia occurs when your body loses heat faster than it can produce it, typically when exposed to cold temperatures for an extended period.
In the context of ice baths, prolonged immersion can lead to a drop in core body temperature, which can have a number of effects from mild to severe.
Contraindications for Certain Medical Conditions
For individuals with heart disease, high blood pressure, or a history of stroke, it is recommended they avoid ice baths due to the potential risks involved. Exposure to extreme cold can lead to sudden changes in blood pressure and heart rate, which can worsen these conditions and potentially be dangerous.
Alternatives to Ice Baths
If you don’t want to take an ice bath, what other options can you try? You may consider trying contrast water therapy, cryotherapy, or compression garments, which all have similar effects to an ice bath.
Contrast Water Therapy
Similarly to an ice bath, contrast water therapy involves submerging in very cold water for a few minutes, however the individual will then swap to more temperate water, typically between 35-45°C. The cycle is then repeated by returning to the cold water.
Contrast water therapy alleviates the effects of staying in cold water for an interrupted period, while also allowing the individual to expose themselves to cold temperatures for longer as a whole.
This method can further improve circulation by creating rapid changes to the circulatory system.
Cryotherapy
Cryotherapy involves exposing your entire body to extremely cold temperatures, typically in a cold chamber. Similarly to ice baths, whole-body cryotherapy constricts blood vessels, reducing inflammation and muscle soreness.
Please note, research on the specific benefits and risks of whole-body cryotherapy is still ongoing and it is recommended you consult a professional before engaging.
Compression Garments
Compression garments can enhance blood circulation and support tissue recovery by applying consistent pressure to the body. These garments work by increasing the blood flow back to the heart, which can help reduce muscle soreness and fatigue.
Compression garments can be a suitable alternative for many athletes who want to optimise their performance.
Ice Baths for Athletes and at Home
For athletes looking to lessen the effects of muscle damage caused by intense training and competition, ice baths can be a physically and mentally stimulating experience enjoyed by many.
Just take care to consult a professional before engaging and while undertaking routine participation.
