Why should underwater swimming hypoxic training drills be avoided?

Underwater swimming hypoxic training drills are associated with increased risks, particularly the risk of drowning. This type of training involves holding one's breath while swimming underwater, which can lead to situations where a swimmer may become disoriented or lose consciousness due to reduced oxygen levels. If a swimmer runs out of breath, the ability to surface quickly can be compromised, potentially leading to dangerous situations, especially in deeper water where help may not be readily available.

While some may believe that such drills can improve swimming skills or aid in lung capacity training, the inherent dangers they pose far outweigh the benefits, particularly for those who are not highly trained or closely supervised during such exercises. Thus, the focus on safety and risk management in swimming training scenarios makes it imperative to avoid these drills.
