Effects Of Cold Water Exposure On The Body

Cold water immersion, such as a cold plunge, has several effects on the body. 

It stimulates the circulatory system, increasing blood flow and causing blood vessels to constrict. This improves blood circulation near the skin and vital organs. When you exit a cold plunge, blood vessels reopen, aiding circulation and improving the immune system. 

Similar effects can be achieved by alternating between hot and cold showers. These responses contribute to potential health benefits associated with cold water therapy.

Physical Benefits Of Cold Water Immersion

1. Enhances Energy

Engaging in a cold plunge can stimulate the secretion of norepinephrine, a hormone that offers several advantages to the human body, including energy production. When coupled with the improved nutrient flow resulting from an enhanced metabolism, cold plunges and other cold therapy methods become effective means to elevate energy levels and enhance exercise performance.

2. Boosts Lung Health

During your initial cold plunge, it’s common to experience breathlessness due to the extreme temperature and the instinct to hold your breath when submerging your head. However, with continued exposure, your lungs gradually adapt, reducing breathlessness and extending your plunging duration.

Research indicates that this adaptation can lead to enhanced lung health and improved lung function. These improvements not only make everyday activities easier but also notably enhance exercise performance, particularly during intense physical activities.

3. Boosts Immune System 

Exposure to extremely low temperatures triggers a rapid increase in metabolic rate, activating the immune system. This heightened immune response results in a significant boost in the production of disease-fighting white blood cells. 

Research on individuals who regularly swim in cold water below 18°C (65°F) demonstrated improved immune responses, elevated levels of leucocytes and monocytes, and reduced stress hormones. It also ensured fewer infections compared to those not engaged in cold therapy. Consistent cold therapy yielded enhanced results, including improved antioxidant responses and increased efficiency in dealing with oxidative stress.

4. Relieves Sore Muscles And Fastens Recovery 

Cold plunges have been shown to offer recovery benefits, especially following competitive sports, reducing fatigue and supporting neuromuscular recovery. These effects are largely attributed to the increased flow of oxygenated blood they induce.

The frigid water prompts your central nervous system to narrow the blood vessels in your arms and legs, directing warm blood towards your vital organs. 

Upon exiting the cold water, your blood vessels expand, facilitating the return of blood to muscle tissue in your extremities and skin. This process not only accelerates muscle recovery and minimises muscle soreness but also provides a valuable workout for the blood vessels, contributing to their long-term strength.

To enhance these effects, taking a hot shower after leaving the icy plunge can further expedite the recovery process.

5. Makes Your Body More Resilient 

Exposing the body to extreme temperatures, be it extreme heat or cold, has been demonstrated to bolster resilience. It forces the body to adapt to the initial stimulus, preventing the onset of shock. 

Regular cold plunges contribute to strengthening the body through a process known as hormesis. Over time, this gradual adaptation enables individuals to endure freezing temperatures with reduced pain or discomfort, thereby increasing tolerance and overall resilience.

6. Elevates Lymphatic Circulation

The lymphatic system, responsible for transporting waste, toxins, and harmful substances away from cells, relies on muscle contractions to circulate fluids. Poor lymphatic function can lead to a cycle of aches, illnesses, and infections. Cold plunges induce muscle contractions throughout the body, providing a significant boost to the lymphatic system, facilitating the efficient removal of waste products and promoting overall health.

7. Relieves Inflammation And Alleviates Joint Pain 

Lowering the body’s temperature through a cold plunge can effectively reduce inflammation. This offers substantial relief from joint pain, making it especially beneficial for individuals dealing with conditions like arthritis. Cold plunges create an environment conducive to healing.

Furthermore, besides their anti-inflammatory properties, cold plunges have shown positive effects on sleep quality. A study involving arthritis patients revealed that cold water treatment resulted in improved sleep quality, leading to lower pain levels during the healing process, which predominantly occurs during sleep.

8. Fires Up Your Metabolism 

Activating brown adipose tissue stores through a cold bath offers the advantage of boosting your metabolic rate. Metabolism is the process through which your body converts the fats, carbohydrates, and proteins from the food you consume into energy.

Studies indicate that cold plunges can elevate your metabolic rate by up to 93%. This has several benefits, including aiding in weight loss, promoting energy production, preventing weight gain, and facilitating efficient nutrient transport to fuel muscle growth.

An efficient metabolism also has additional advantages, such as maintaining balanced blood glucose levels and increasing insulin sensitivity, both of which play a pivotal role in your overall health and fitness.

9. Improves Health Of Hair, Nails And Skin

The increased blood flow induced by cold plunges serves to nourish and activate hair follicles, promoting thicker hair growth, preventing hair loss, and even encouraging regrowth, particularly noteworthy for cancer patients undergoing chemotherapy who often use ice caps for this purpose.

Cold exposure also has the ability to minimise pore size, firm the skin, and regulate oil secretion, ultimately preventing greasy hair and acne while maintaining the health, moisture, and smoothness of hair and skin.

Moreover, the enhanced skin health and nerve-calming effects of cold therapy make it an effective treatment and preventative measure for conditions like hives, eczema, chronic itching, and various other skin issues.

10. Fastens Weight Loss By Activating Brown Fat

Exposure to extremely cold temperatures triggers the activation of brown fat, also known as brown adipose tissue (BAT), in the body. This activation initiates a process called thermogenesis, which elevates the body’s internal temperature.

During thermogenesis, there is a remarkable increase in the oxidation of the body’s fat cells, with studies indicating that fat can be burned twice as efficiently during this state. This heightened fat-burning occurs because the body requires fat to produce the energy necessary to generate the additional heat it needs.

Utilising a cold plunge is an effective method to enhance weight loss, especially when combined with a balanced diet, regular exercise, and a consistent sleep routine. Furthermore, there is evidence to suggest that regular cold exposure can facilitate the conversion of unhealthy white fat into beneficial brown fat, further augmenting this weight loss effect.

11. Improves Blood Circulation And Heart Health

Exposure to cold temperatures can significantly improve circulation and heart health. This not only aids in reducing inflammation and enhancing recovery, but it also contributes to improved heart health. 

Cold water immersion, such as cold plunges or swimming in cold water below 5°C (41°F), has demonstrated positive impacts on various bodily functions, including the cardiovascular, endocrine, and immune systems, as well as mental well-being. It’s a potential preventive measure against cardiovascular disease and hypertension, and it can alleviate symptoms and reverse these conditions in those who have developed them. 

This practice influences the entire body, offering benefits such as pain relief, improved circulation, and enhanced overall health.

12. Stabilises Blood Pressure

A cold shower can contribute to lowering high blood pressure by enhancing blood flow and the efficiency of the circulatory system. This, in turn, leads to a reduction in heart rate, ultimately aiding in the control of blood pressure. 

A study on hypertensive patients even found that immersion in water as warm as 20°C (68°F) could lower heart rate and blood pressure by up to 12%, with more significant results observed at lower temperatures.

Mental Benefits Of A Cold Plunge

1. Improves Sleep Quality

Elevated cortisol levels due to stress are a common cause of poor sleep and weight gain. Cold water plunges, by relieving stress, can improve sleep quality. Regular cold water plunges empower better mental control, enabling faster relaxation and deeper sleep. Plunging before bedtime can enhance the benefits by engaging the autonomic nervous system’s destressing effects, leading to even higher sleep quality.

2. Stress Relief

The initial activation of the sympathetic nervous system during a cold plunge induces a state of stress. However, this strengthens the parasympathetic nervous system, responsible for rest and relaxation, ultimately aiding stress reduction. 

The reinforced parasympathetic system grants you greater control, allowing conscious activation for stress management. It also improves your autonomic nervous system and heart rate variability, preparing your body to cope with stress even without conscious intervention.

3. Boosts Mental Clarity, Discipline, And Focus

Extreme temperature exposure shifts your brain into survival mode, enhancing attention and focus by releasing norepinephrine. Regular ice-cold water plunges help you channel this focus into other areas of life, benefiting physical and mental health as well as overall well-being. 

These cold exposures also elevate the production of neuroprotective proteins, enhancing mental clarity and potentially preventing degenerative neurological diseases like Alzheimer’s.

4. Enhances Mood And Prevents Depression

Cold plunges activate the sympathetic nervous system, elevating beta-endorphin and noradrenaline levels in your blood, along with an increased synaptic release of noradrenaline in the brain. Low levels of norepinephrine are linked to depression and other mental health issues, while higher levels energise the brain and improve alertness. 

Many antidepressants are developed based on compounds that enhance norepinephrine production. Cold water plunges also send electrical impulses from peripheral nerve endings in cold receptors to the brain, alleviating depression symptoms and promoting a happier, healthier mental state.

FAQs 

1. Can cold water swimming make you fall sick?

For a healthy adult, cold immersion should generally be safe without adverse side effects. This safety is attributed to the typically short duration of a cold plunge, which usually does not lead to a significant drop in core body temperature. 

Staying within the recommended guidelines, which suggest immersion for no longer than 10 to 15 minutes and in a water temperature range of 10°C to 15°C, is crucial.

It’s essential to note that exceeding these parameters can pose risks of complications, such as hypothermia or frostbite. There’s also the possibility of hyperventilation, making it important to focus on controlled breathing during a cold plunge. 

To ensure safety, especially for newcomers, having someone nearby during the initial attempts is advisable. This precautionary measure can be vital in case of fainting or loss of consciousness during the cold plunge.

So, when adhering to the recommended time and temperature ranges, cold water plunges are generally considered safe for healthy adults. Still, vigilance and sensible precautions are essential to mitigate potential risks associated with extreme cold exposure.

2. How is a cold plunge different from an ice bath?

An ice bath can be a DIY bathtub or a similar container filled with ice, while a cold plunge refers to any situation where you can immerse your body in water with a temperature below a specific threshold.

This distinction implies that an ice bath can be categorised as a type of cold plunge, but not all cold plunges necessarily involve ice baths. Ice baths are considered one of the most extreme forms of cold plunges, as they typically reach the lowest end of the temperature range that is considered safe for such practices.

While ice baths indeed provide the comprehensive benefits associated with cold plunges, it’s crucial to recognise that they are best suited for individuals with more experience in cold exposure.

3. Can cold plunging tighten the skin?

Cold water has the effect of causing the blood vessels in your extremities to contract and narrow when you’re in the cold plunge, and then they expand and allow a heightened blood flow once you emerge from the cold water. This process also involves the closure of your pores, preventing excessive oil secretion that can contribute to the development of acne and skin blemishes.

As a result, cold plunges contribute to giving your skin a more toned, firmer, and suppler appearance, along with a healthier and radiant glow.

4. When is the best time for cold plunging?

The ideal timing for a cold plunge may vary depending on your specific goals and desired potential benefits.

For most individuals, the best time to engage in a cold plunge is in the morning, especially as a way to kickstart the day. It serves as a refreshing and invigorating experience, helping you become alert and energised, setting a positive tone for the day ahead.

However, if your aim is to harness the sleep-enhancing properties of cold plunges, the optimal time to take one is right before bedtime. Doing so maximises the relaxation effects, allowing you to quickly ease into a deep and restful sleep, promoting overall sleep quality.
