The Sleepless Divide: Why Women Report Worse Sleep Next to Their Male Partners

One of the most immediate and tangible reasons for disrupted sleep is the physical presence of a partner, which can introduce motion and noise. Men are statistically more likely than women to suffer from obstructive sleep apnea (OSA) and are more frequently reported to be loud snorers. Snoring, in particular, is a significant objective disruptor. While the sleeping partner may not fully wake up, the brain can register the sound, leading to fragmented or lighter sleep—a phenomenon known as "micro-arousals." Because women tend to be lighter sleepers and are generally more sensitive to noise, the vibrations and sounds generated by a male partner's louder or more fragmented breathing can constantly pull them out of deeper sleep stages.
