Another major factor is the total amount of sleep you get over a period of several days. 8 hours of sleep a night should give you the alertness you need to be productive throughout the day, but if you have a sleep disorder or if you get less than 8 hours of sleep a day for several days, you can start building a sleep deficit that makes it difficult for the brain to function. If you average four hours of sleep a night for four or five days, you develop the same level of cognitive impairment as if you’ve been awake for 24 hours—equivalent to legal drunkenness.

Dr. Stan Farrell has extensive training in treating sleep apnea and other sleep disorders. Dr. Stan Farrell offers one of the leading alternatives for the CPAP, which is an oral appliance that can be used in conjunction with a CPAP or as a stand-alone oral appliance depending on the severity of the individual’s OSA.
