Obstructive sleep apnea is common in older adults. People with sleep apnea stop breathing for as long as 30 seconds at a time. These interruptions can happen hundreds of times a night. Obstructive sleep apnea occurs when the muscles in the back of your throat relax, narrowing your airway and cutting off your breathing.
