Is swimming in cold water really good for you?
Cold water swimming is a great immune system booster. Some studies have shown that water swimmers suffer fewer and milder respiratory infections and illnesses including the common cold (3,4). Cold water exposure also releases leukocytes into our bloodstream, a blood cell that helps fight disease and infection (7). It’s a good idea to ensure you have fuelled yourself properly before a cold swim to ensure your body has adequate carbohydrates to fuel the shivering after your swim.Enter the water slowly, giving your body at least 30 seconds to acclimatise after the initial cold shock response before swimming or putting your face near the water.

When worn snugly so that there is minimal flow of water into and out of the suit, a thin layer of water is trapped between the suit and the skin, allowing that layer of water to warm up to body temperature.When the water temperature measures between 50 and 65 degrees, wetsuits are strongly encouraged, and some races may require their use. Between 65 and 78 degrees, it’s typically the athlete’s choice of whether to wear a wetsuit.Wetsuits use a layer of water (that is warmed by the wearer’s body) to help keep the body insulated, while drysuits use a layer of air and are fully sealed to prevent water from entering and coming into contact with the skin.

Thermals are specifically designed for colder weather and offer enhanced insulation. On the other hand, base layers are more versatile and can be worn in various climate conditions, focusing on wicking moisture and regulating body temperature.Wearing thermals is perfect for winter sessions out on the water. Even in a warmer climate, the water can remain cold. Using quality thermals can provide significant insulation to help regulate body temperature, whether you are diving underwater or surfing in the wind.

To generate this heat, your body needs to ramp up its metabolic activity, and in doing so, it burns more calories. Over time, regular cold water swimming sessions could support weight loss or weight management goals, provided they are part of a balanced, healthy lifestyle. Cold-water immersion triggers the release of important hormones and neurotransmitters, such as dopamine, serotonin, cortisol, norepinephrine, and β-endorphins, which are all linked to modulation of the neural responses to stress and other emotion-related circuits affected in depression, anxiety, and posttraumatic .Even when swimming hard, after a length of time in a cold pool, your core temperature will be slightly lowered. In addition, your body is expending more energy to maintain that temperature, which leads to greater fatigue than normal.We measured brain connectivity and self-reported emotional state before and after cold-water immersion. Our findings showed that participants felt more active, alert, attentive, proud, and inspired and less distressed and nervous after having a cold-water bath.The cold can dull your blood pressure response and make you feel dizzy and faint.
