MYTH: For better sex, practice stopping your urine flow. TRUTH: Kegel exercises utilize the same (pelvic) muscles but should be performed on an empty bladder, "otherwise you increase the risk of infection," says Dr. Jill Rabin, a New York OB/GYN and co-author of Mind Over Bladder. For best results, hold for five seconds and release for 10; repeat 10 sets of five a day.
MYTH: You sleep better alone. TRUTH: Your partner's comforter-snatching habit can rob you of a few Z's, but an ongoing University of Pittsburgh study hints that being part of a happy couple can lead to better sleep. The reason? A mate makes you feel safe and can encourage you to get help for sleep conditions you wouldn't have noticed on your own.
