“Sex can be a significant workout,” Dr. Greenblatt says. “You can burn anywhere from 85 to 250 calories every time you have sex.” Not only do you burn calories, but you work different muscle groups, depending on how many different positions you try.
Sex boosts your your immune function.
“People who have sex also tend to have higher levels of immunoglobulin A, which improves your immune function,” Dr. Greenblatt says.
Sex helps protect your heart.
Research suggests that people who have frequent sex have a 50 percent less chance of cardiovascular mortality, compared to people who don’t have sex as often. Not only that, but according to Dr. Greenblatt, it can boost your body’s production of Vitamin D, and estrogen, which helps you to maintain shiny hair and skin.
Sex can relieve pain.
Immediately before you have an orgasm, levels of oxytocin are five times higher than normal, Dr. Greenblatt says, and that can relieve pain, from back pain to arthritis, and even menstrual cramps.
Admittedly, many researchers are quick to stress that sex and health is like the old “chicken and egg” adage—that is they’re not sure which came first. It could be that people who live healthier lifestyles tend to be more interested in sex than those who are not as healthy.
Another important health tip: Don’t forget that it’s still vital to practice safe sex at all times.
