The key to a sex life that's out-of-this-world-amazing starts in bed.
But don't get too far ahead of yourself—we mean sleep.
"Everybody’s sleep requirement is different," says Bruce Corser, M.D., MBA, the medical director at the Sleep Management Institute in Cincinnati, Ohio. And while experts typically recommend 8 hours a night—a number that has stirred plenty of debate—Corser says it can vary from person to person. "The average self-reported sleep is 6.8 hours nightly," he explains. "But some people need more than 9, and some people function consistently well on less than 7 hours of sleep."
Of course, optimizing your sleep for your sex life also means optimizing sleep for whomever's sleeping with you. And while sleep necessity can very from person to person, men and women tend to have distinct issues related to sleep. Women, for example, take longer to fall asleep than men, but they tend to fall asleep earlier in the night and wake up earlier in the morning. (They also have a greater probability of developing insomnia and Restless Leg Syndrome.) Men, on the other hand, are two times more likely to develop sleep apnea—which often translates as loud snoring or awakening with gasping.
"In order for couples to have a harmonious relationship, these differences need to be acknowledged," Corser says.
