Sleep Apnea Dim Light May Lead to Depression
CLARK POWELL: After years of struggling with the symptomsof sleep apnea, Jack Chapman says using a CPAP machine has changed his life overnight. JACK CHAPMAN: A complete difference in how you feel all day you wake up refreshed. POWELL: While this machinemay have helped Jack with his physical symptoms, a new study is shedding light on the psychologicalsymptoms of sleep apnea. DR. MAGALANG: In patients with obstructive sleep apnea, there is a very highincidence of having depression.
POWELL: Ulysses Magalang is a sleep expert at the Ohio StateUniversity Wexner Medical Center. He says half of all patients with obstructive sleepapnea also have depression. And now, as subtle as it may seem, they may have found one ofthe reasons. DR. MAGALANG: Light at night, even low levels of light, may actively suppress the secretionof melatonin. POWELL: And in lab experiments with mice, that led to depression and anxiety.Rooms like this may seem fit for sleep, but
there are several problems. TV's can causesignificant sleep disruption, and even when they're off, lights from control boxes cancause problems. So can alarm clocks. Even though the experiments were done in mice,researchers say the evidence is compelling enough to prompt changes in humans. DR. MAGALANG: If youhave obstructive sleep apnea, it would be better if you can sleep in a darkened environmentand avoid even low levels of light. POWELL: Jack says his sleep apnea hasn't caused depression,but he appreciates the fact that researchers
are shedding new light on how important itmight be to sleep in the dark. At Ohio State's Wexner Medical Center, this is Clark Powellreporting.
Depressed and Exhausted It Could Be Something More
A bad night's sleep can make you feel tiredand unfocused during the day. If left untreated, that cycle may become more than just an inconvenience.I'm Shelby Cullinan with your latest health news. A new study found that untreated sleep apneamay be linked to depression in adult men. Obstructive sleep apnea, or OSA, is a disorderin which breathing stops or is interrupted periodically during sleep. It is usually causedby an obstruction in the airway â€” often due to the jaw sinking into the throat, closingoff the airway. The researchers found that men with undiagnosed severe OSA were twiceas likely to have depression than men without
OSA. Men with excessive sleepiness duringthe day also had a higher risk of depression. Additionally, men with both OSA and daytimesleepiness were almost five times as likely to have depression as men without OSA anddaytime sleepiness.
