What happens to your body after cold water swimming?
The cold can dull your blood pressure response and make you feel dizzy and faint. Now that you are out of the water doesn’t mean you will instantly start to warm up. In fact you will continue to cool, sometimes called the ‘afterdrop’. This period of cooling can potentially last 30-40 minutes after your swim. Be Consistent. To minimize the cold shock response and develop lasting cold tolerance, swimmers must commit to regular cold water immersion. Aim for at least one cold water swim per week, gradually increasing duration and intensity over time.When winter swimming without a wetsuit, a rule of thumb is 1 minute in the water per 1oC of water temperature, so for those new to winter swimming 2 or 3 minutes is more than enough. Only enter cold water if you can tread water and are a confident swimmer.Cold water can cause cold water shock and hypothermia, and can impact people of all ages and fitness, including even the most capable swimmers. These conditions can adversely affect the body’s ability to function properly, thereby increasing the risk of drowning.Mental Health Improvements: Individuals suffering from depression experienced significant mood improvements after participating in cold water swimming. Calorie Burn: Cold water swimmers can burn up to 500 calories in a 30-minute session, depending on water temperature and intensity.The secret to acclimatising to cold water is just to swim in it, often – at least once a week, and preferably two or three, gradually extending the time that you stay in the water,’ says Dr Heather Massey a swimmer and a researcher at the Extreme Environments Laboratory at the University of Portsmouth.
Is swimming in cold water good for your health?

Cold plunge ice baths may have several benefits, such as burning body fat, improving insulin resistance, and reducing stress, among others.Cold water therapy has been reported to benefit the body in many ways, including: reducing muscle pain and stiffness after exercise, by reducing swelling and inflammation.There is some evidence that cold plunges may increase white blood cells which may boost the body’s ability to fight infection. However, those studies were mostly conducted on cold water swimmers, so it could have been the exercise and not the temperature of the water.Cold Water Immersion Therapy may have the potential to significantly decrease and/or prevent the symptoms of dementia-associated conditions, including Alzheimer’s disease.There’s no evidence that cold showers help with weight loss.

Don’t swim in colder water for longer than 10 minutes, and avoid using how you feel as a guide — cold incapacitation can occur with little warning. By submerging yourself into cold water, your blood vessels narrow, and your heart rhythm becomes disturbed. This can put your body into shock and can cause a cardiac arrest. Always try to submerge your body gradually and try to control your breathing.How to minimise the risk of cold water shock?

A correctly fitted lifejacket or buoyancy aid will help you remain calm and afloat if you do enter the water.Cold water shock can occur when your body undergoes sudden immersion in cold water that is less than 15°C. It causes uncontrollable breathing and increases the work of the heart, which can lead to hypothermia and drowning.Cold water swimming can lower your body temperature, leading to hypothermia. This is a serious condition where your core temperature drops below 35°C and affects your vital organs. Symptoms include shivering, confusion, drowsiness, and slurred speech.

If you swim with a buddy or in a group the chance to share and compare your experience with like-minded people intensifies the experience.Furthermore, cold water temperatures pose additional risks to the immersed swimmer, including the initial “cold shock” and hyperventilation [18] and potential risk of hypothermia [11,12]. With the cold stress experienced during cold-water immersion and swimming, the respiratory system is under high constraints.Recovery and Rest After each swim, allow your body to return to normal temperature slowly and safely. Wrapping yourself in warm blankets, drinking hot fluids, and avoiding sudden heating (like jumping into a hot shower) can prevent afterdrop phenomenon – where body temperature continues to drop after exiting the water.

When you immerse yourself in cold water, your body’s fight-or-flight response is triggered, which releases cortisol – the stress hormone. The more often you take dips in cold water, the more your brain gets used to the cold and lowers these stress hormones.
