To Stay Calm and Collected During That Big Presentation

How sex helps: Your body won't react as strongly to the stress.
The science: People who'd had intercourse frequently in a two-week period experienced a smaller spike in blood pressure compared with people who engaged in other forms of sexual activity or no activity at all when, during the experiment, they were asked to speak in public or do math out loud (the horror), found a small study in Biological Psychology. Your body releases oxytocin (the love hormone that's also been shown to reduce stress) during sexual activity, particularly when you orgasm, and because intercourse may feel more intimate than other sexual activities, the researchers speculate that it could produce more oxytocin activity.
