    • A nasal air flow control device is provided, the device comprising one or more nasal inserts, each nasal insert comprising an insert body having a wall, a proximal end and a distal end, the insert body comprising a cavity extending between the proximal end and the distal, the insert body having at least one proximal opening in the wall at the proximal end of the insert body and a distal opening in the wall at the distal end of the insert body; and a valve member disposed in the cavity and moveable therein between a first position and a second position; wherein the portion of the wall at the distal end of the insert body defining the distal opening comprises an inlet portion defining an inlet, a valve seat portion spaced apart from the inlet portion and defining a valve seat, and a throat portion disposed between the inlet portion and the valve seat portion defining a throat; wherein when the valve member is in the first position, it contacts the valve seat portion and closes the distal opening, preventing air flowing through the cavity in the insert body; and wherein when the valve member is in the second position, it is displaced from the valve seat portion and both the proximal and distal openings are open, allowing air to flow through the cavity in the insert body.
