Dr. Laura Berman, a relationship and sex therapist, stated in a MSNBC article that "Snoring is a 'big relationship divider' ... Complications include 'low energy from not getting enough revitalizing sleep, making you grumpy, less communicative, and with less sexual energy."
Although snoring is the most talked about sleeping problem of married couples, other shared sleeping issues include cold feet, bathroom trips, weight of blankets, sleep talking, bedroom temperature, nightmares, different body clocks, restless legs, grinding teeth, insomnia, shift work, sleeping apart, tossing and turning, stealing sheets, sleep walking, and more.
