In honor of Valentine’s Day, I’m going to summarize a few studies that show how sex is good for your health. Ladies, be careful telling your husbands about the last one. 
Happy Valentine’s Day!
- Sex reduces stress. A 2006 study, published in the journal Biological Psychology found that those who had sexual intercourse had better responses to stress (in this study, the stressors were public speaking and verbal arithmetic).
- Sex boost immunity. A study at Wilkes University in PA found that college students that had sex 1-2 times per week has significantly higher levels of immunoglobulin A (IgA) than students that has less frequent sex (and interestingly also more–3+ times per week). IgA is an important component of the immune system.
- Frequent ejaculation reduces risk of prostate cancer. This study‘s results are a bit absurd (at least from a woman’s perspective) but basically found that the more a man ejaculates between the ages of 20 and 50, the less his chances of developing prostate cancer. Men who ejaculated 7 times or more each week in their 20s were 1/3 less likely to develop aggressive prostate cancer than those who “only” ejaculated 3 times each week.
