The DRS stands for Drag Reduction System, which enables a car to open its rear wing to limit the downforces on the car. This increases the car's theoretical performance and in theory facilitates passing.
The nonsurgical treatments for obstructive sleep apnea include behavior therapy, including weight loss, medications, dental appliances, continuous positive airway pressure, bi-level positive airway pressure, and auto-titrating continuous positive airway pressure.
