Answer 2

As we sleep, breathing slows down and we do not take in or expel as much air as when awake. As muscles relax during sleep, the upper airway narrows and leads to 200% increase in upper airway resistance. As a result, respiratory muscle activity is reduced and increased work of breathing is needed.
