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.
Sleep apnea facts. 1  Sleep apnea is defined as a reduction or cessation of breathing during sleep. 2  The three types of sleep apnea are central apnea, obstructive apnea, and a mixture of central and obstructive apnea.  Central sleep apnea is caused by a failure of the brain to activate the muscles of breathing during sleep.
Sleep apnea is a condition in which you stop breathing in the middle of the night, often several times a night. The deprivation of oxygen, as well as the constant sleep disruption, leads to constant daytime sleepiness, lethargy, and fatigue. It is also associated with more-serious conditions, such as heart disease, diabetes, and obesity.
