The old saying that, "An apple a day keeps the doctor away" is true, but having an orgasm a day works just as well and has extra benefits! This is by far the ultimate health stimulus plan. If you want to live a long, vibrant life with your spouse filled with excitement that keeps your sexual appetite into your golden years then read on.

Medical research has revealed enormous data proving that sexual climax (orgasm) has resulted in as many as 55 reasons to have sex on a regular basis. We're focusing on just the top seven major health crises that are helped by climaxing regularly for both men and women. In order for the optimal health benefits, having an orgasm every 24 hours keeps the health benefits at their maximum and the levels of oxytocin, estrogen and testosterone consistently flowing. Any increase in sexual frequency is beneficial, and for those who are alone, masturbation with orgasm is a perfect substitute—so love yourself!

1. Increases Immunity to Infection
Good sexual health may mean better physical health. Healthier people usually are happier as well, which also means that we are taking better care of ourselves. Science has proven that having sex once or twice a week has been linked with higher levels of an antibody called immunoglobulin A or IgA, which can protect you from getting colds and other infections. This includes reducing the possibility of getting the H1N1 infection in addition to the flu!

2. Improve Cardiovascular Health
Getting your blood flowing through sexual activity keeps blood flowing to all of the right spots, starting with your heart. Starting as young married, increasing the frequency of sexual activity, directly correlates to healthier blood vessels and heart function. Researchers also found that having sex twice or more a week reduced the risk of fatal heart attack by half for men, compared with those who had sex less than once a month. Reducing heart disease also reduces erectile dysfunction, which causes the penis to not maintain an erection.

3. Reduce Risks of Prostate Cancer
Frequent ejaculations, especially in 20-something men, may reduce the risk of prostate cancer later in life. Research reported in the British Journal of Urological Health found men who had five or more ejaculations weekly while in their 20s reduced their risk of getting prostate cancer later in life by a third. Another study, reported in the Journal of the American Medical Association, found that frequent ejaculations, 21 or more a month, were linked to lower prostate cancer risk in older men, as well, compared with less frequent ejaculations of four to seven times monthly.

4. Decrease Incontinence for Men and Women
Who wants to be wearing adult diapers if it can be avoided? The muscles used while having sex are called the PC muscles. Both men and women have them and women are often advised to do Kegel exercises to strengthen them in order to keep incontinence at bay. But these are the same muscles used during orgasm in both men and women. Squeezing these muscles together during climax strengthens them the same way, but is way more fun! To start strengthening them, men and women need to find where the PC muscles are located. To do this, try to stop the flow of urine several times during urination. The muscles you're squeezing are the PC muscles and are the ones you should focus on during intercourse. The squeezing motion gives more sensation to the penis and vagina and will intensify the sexual experience and keep away the diapers!

5. Reduce the Possibility of Osteoporosis
Bone loss during our elder years can be devastating with increased chances of hip or bone fractures. Both testosterone and estrogen levels experience a boost through regular sexual activity. Testosterone does more than just boost your sex drive. Testosterone helps fortify bones and muscles. Since men and women both have testosterone, turn up the heat and get sexy! Nobody wants to be an invalid as we age. Keep doing those pelvic thrusts and push-ups while having sexual activity and let your body keep those bones healthy and strong.

6. Increase Longevity
Who doesn’t want to live longer and look younger as we age? Well, research shows that maintaining a healthy sex life can add three to seven years to your life and keeps your skin looking younger. Throw away the Botox and stay healthier the sexy way. Surveys show that happy couples live longer. Every time you reach orgasm, the hormone DHEA (Dehydroepiandrosterone) increases in response to sexual excitement and ejaculation. DHEA can boost your immune system, repair tissue, and even work as an antidepressant. Meaning, a health benefit of sex, if you keep the orgasms coming, is potentially a longer life.

7. Burns Calories
Would you rather run on the treadmill or have sex? Just 30 minutes of sexual activity (that results in orgasm) burns an average of 150 calories. Sex, like exercise, releases endorphins—your feel good hormones. It gives you the same runner’s high that exercise provides. If you have sex for an hour, that is 300 calories per session at three to seven times a week, you will lose weight while having fun with your intimate erotic friend, your spouse!

The health benefits of regular orgasmic sex are bountiful and our bodies naturally want to stay healthy. In order to accomplish this you have to use it or lose it. Staying sexually connected isn’t the key to happiness, but it is a great way to increase the emotional part of your relationship, keep healthier and live longer. Your life and your marriage will flourish as a result and your kids will learn that a passionate connection is a happier family as well.
