What does it feel like for soldiers to use hyperbaric oxygen chambers?

The soldier entered the hyperbaric oxygen chamber and felt an unusual pressure. As the cabin door slowly closed, the outside noise gradually faded away, replaced by a quiet and profound atmosphere. As the oxygen concentration gradually increases, their breathing becomes smoother, as if each inhalation can inject more vitality into the body.

In the hyperbaric oxygen chamber, soldiers may feel a slight tinnitus, which is a normal phenomenon caused by changes in pressure. But over time, they will gradually adapt to this environment and even begin to enjoy the feeling of relaxation and recovery for their body and mind.

For soldiers who frequently engage in high-intensity training and combat, hyperbaric oxygen chambers can not only help them relieve fatigue and restore physical strength, but also improve their body's immunity and resistance to a certain extent. Therefore, for soldiers, hyperbaric oxygen chambers are a valuable recovery and training tool.
