The function of the nose clip When swimming, the water waves generated by the body often cause water to enter the nostrils, leading to choking and coughing.The nose clip primarily serves to allow you to breathe through your mouth instead of your nose, preventing water from entering the nostrils and avoiding choking. It is recommended that beginners use a nose clip, while those who have already learned to swim should gradually remove the nose clip and consciously breathe through their mouth. This way, even if swimming for a long time, they will not feel uncomfortable.In addition to this, nose clips are mainly suitable for those practicing turns and water aerobics. The most commonly used nose clips currently have rods made of PC material with good elasticity, and the nose clip pads are made of ultra-soft silicone, making them quite comfortable, secure, and durable. Some people don't like to wear nose clips while swimming because they often cause a lot of pain to the nose. However, by choosing a nose clip size that suits the height of the nose bridge, discomfort can be reduced. The time to wear the nose clip should not be too long, preferably not exceeding two hours.
