The diving mask can improve the eyesight of the diver in the water, and it also plays a role in preventing the eyes and face from being irritated by water. Face masks are divided into full face masks and half-face masks. Wearing a flat diving mask, people can see clearly underwater. This is because the flat window of the diving mask separates the eyes from the surrounding water by a layer of air.
The Role of Diving Mask
The shape of this mask is a cartoon shark that children like very much, so it can arouse children’s interest greatly. However, if the child is relatively young, it is not suitable for diving. So we can wear this mask while swimming.
Children go swimming. On the one hand, it can make the children’s bones grow better and promote the growth of muscles. On the other hand, it is good for the development of children’s joints. After swimming, children can make the body more symmetrical, and the body shape is better. However, resistance is getting higher and higher. According to incomplete statistics, children who often swim are at least twice as healthy as the average child.
Moreover, the continuous activities of the limbs during the swimming process of children can improve the flexibility of the body. At the same time, it can also greatly help the functional development of the brain and promote the brain’s response to the external environment. Some children often cry and can be corrected by swimming.
When we are swimming, the pressure on the chest is relatively large, and then the muscles are stimulated by cold water to tighten, and the human body will find it difficult to breathe. Therefore, swimming can force people to breathe hard and increase the depth of breathing so that the amount of oxygen inhaled can meet the body’s needs. In other words, every breath you take underwater is a deep breath.
