According to safety guidelines, children under what age should be supervised in swimming pools?

Children under the age of 8 should be supervised in swimming pools according to safety guidelines. This age limit is established to help ensure their safety, as younger children are often less capable of understanding danger in aquatic environments. Supervision by a responsible adult or a lifeguard is crucial because young children may not have developed the swimming skills or judgment necessary to respond appropriately in emergencies. This guideline is designed to minimize the risk of drowning and other aquatic accidents, recognizing that younger children are more vulnerable and require attentive watchfulness while in or near water.
