apnea

Take, for instance, those with sleep apnea, in which breathing periodically stops and starts throughout the night.

Snoring is a sign of obstructive sleep apnea, when your airway collapses or becomes blocked during sleep.

Sometimes people with sleep apnea wake up during the night gasping for breath.

More troubling were the episodes of central apnea we had been warned about.

And in other research, people with sleep apnea were found to have more difficulties with sexual function.
