A personal entertainment respiratory apparatus provides air to a user to provide a fully immersive entertainment experience. The personal entertainment system may comprise a flow generator for providing the flow of air. A personal spatial respiratory interface may be coupled to the flow generator. The personal spatial respiratory interface may comprise an outlet for the flow generator. The personal spatial respiratory interface may further be configured to direct the flow of air within an ambient breathing proximity of a user. The personal entertainment respiratory apparatus may further comprise a controller and a sensory particle dispenser. The controller and sensory particle dispenser may be configured to selectively activate release of a sensory particle from the dispenser into the directed flow of air in response to an entertainment triggering signal.

A nose clip structure includes a nose frame and nose pads. The nose frame includes two arms and a connecting portion. The connecting portion interconnects the two arms to make the two arms bend flexibly. The nose pads are disposed on the two arms of the nose frame, and has an anti-off body adapted to engage with the wing of the swimmer's nose for preventing falling-off of the nose clip structure.

In some embodiments, a face soaking device may have a vessel, a vessel neck gasket, and a breathing apparatus. The vessel may be configured to hold a liquid to submerge a face of a user or a portion thereof. The vessel neck gasket may be (removably) joined to the vessel. The vessel neck gasket may be configured to comfortably accommodate a front portion of the user's neck. The breathing apparatus may be in removable contact with: the vessel, with a head rest subassembly, and/or with the user. The breathing apparatus may be configured to permit the user to breathe while the user's face may be submerged within the liquid. When the vessel may be filled with the liquid to at least a sufficient level, the user may soak the face or the portion thereof, such that the skin being soaked receives a benefit.

A hypothermia-prevention device is provided. The hypothermia-prevention device provides a three-port valve system having an inhalation port, a respiration port and an exhalation port, respectively wherein an in-take valve fluidly connects the inhale port to the respiration port and wherein an out-take valve fluidly connects the exhale port to the respiration port. The out-take and in-take valves are adapted to respond to the negative and positive pressure urged by way respiration of a user through the respiration port so that the exhale air is directed through the exhale port while colder inhale air is excluded through the exhalation port. The exhale port provides an out-tube for selectively directing the warmer exhale air to necessary body parts of the user.

Body-worn air-treatment devices include a body that is configured to be selectively coupled proximate to a respiratory tract inlet of a living individual, and a pathogen-deactivating mechanism that is supported by the body. Methods include deactivating pathogens proximate to a respiratory tract inlet of a living individual.
