00:00Sex before an important event may lower your level of stress.
00:04Looks like sex may just help your grades on your university final exams.
00:08A 2006 research study published in the journal Biological Psychology
00:13had subjects take part in stressful activities.
00:16These included giving a public speech or taking a difficult math quiz.
00:21Subjects who had sex before the test had lower blood pressure and lower levels of stress.
00:25This was then compared to those who had no sex,
00:28those who masturbated, and those who had sexual contact without intercourse.
00:32The study even claims that penile-vaginal intercourse, PVI,
00:36but not other sexual behavior is associated with better psychological and physiological function.
00:42You may just have to thank not only yourself, but your partner as well,
00:46for that A plus on your math exam.
00:48So, which of these were you most surprised to hear about?
