Apnea Training is a technique used to improve breath-holding ability and enhance overall lung capacity. It is commonly practiced by free divers, athletes, and individuals interested in improving their respiratory efficiency. The training involves gradually increasing the duration of breath-holding through specific exercises and relaxation techniques. This training can also help individuals manage stress and anxiety by promoting better control over their breathing patterns. By learning to hold their breath for longer periods, participants can develop a deeper understanding of their body's responses to low oxygen levels, which can be beneficial in various physical activities and sports.
