Is swimming in cold water good for you, NHS?
Some people go further than just swimming and try cold water therapy and outdoor swimming, due to the even bigger release of endorphins. When we submerge our body in cold water, blood rushes around to try and keep us warm and this creates excellent blood flow and even a level of pain relief.

Only enter cold water if you can tread water and are a confident swimmer.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. If you have difficulty swimming because of the cold, move onto your back and move your limbs as little as possible whilst staying afloat.Cold water swimming – sometimes referred to as open water swimming, wild swimming or sea swimming – is a great way to stay fit throughout the year. Swimming for just 30 minutes a week can even help to guard against heart disease, stroke and type 2 diabetes.Gradually wading into the water is far better than rushing in at once. Entering the water gently allows your core body temperature to cool more slowly, and you get used to the water as temperatures drop. Keep your head above the surface if you’re new to cold water swimming, as the arteries may constrict.Our heart works harder when we’re moving through water than when we’re on land.

Is it good to swim in cold water in winter?
The cold helps to reduce inflammation and ease pain. Alertness: The shock of winter swimming is like an adrenaline rush, increasing heart rate and oxygen intake. As a result, you feel more alert. Increased metabolism: Many say swimming in cold water improves their metabolism and aids weight loss. In fact, growing evidence about the benefits of cold-water swimming suggest that getting cold on the regular may support a healthy immune system. As with exercise, cold immersion stresses the body in such a way that it can prime the immune system to fight back.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.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.If you jump into cold water too fast, it can shock your body and cause problems with your breathing, heart rate, blood pressure, or mental state.

What is the secret to cold water swimming?
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. As your body continues to lose heat to the cold water, you may experience the cold shock response, which typically occurs during the first 1-3 minutes of immersion. During this phase, you may gasp for air, hyperventilate, and experience an increased heart rate and blood pressure.Cold water shock can be life-threatening. If you enter the water when the temperature is below 15°C, your body will instinctively want to protect itself. This reaction can be very dangerous as cold water shock causes you to gasp for air involuntarily.Understanding the Cold Water Effect: Firstly, your heart rate increases and your blood vessels constrict in an attempt to conserve heat. This sudden change triggers the release of stress hormones like adrenaline and cortisol, preparing your body for the cold shock.How to minimise the risk of cold water shock? Always consider the temperature of the water and wear appropriate clothing for the activity you’re doing. A correctly fitted lifejacket or buoyancy aid will help you remain calm and afloat if you do enter the water.
