How long can an child stay underwater?

The length of time a child can safely stay underwater varies based on factors such as age, swimming ability, and comfort level. Generally, younger children may hold their breath for around 10 to 20 seconds, while more experienced swimmers can manage 30 seconds or longer. However, prolonged periods underwater can lead to risks such as drowning or hypoxia, so supervision and safety measures are crucial. It's important to ensure children are aware of their limits and to teach them safe swimming practices.
