We all know that sex can be fun and pleasurable but did you know that it has medical benefits?

On average, if a couple engages in sex 1 or 2 times a week, higher levels of immunoglobulin A (IgA) is produced for each partner increasing the overall benefits to their health.

IgA is an immune system protein that protects the mouth and upper respiratory system from viruses.

Here are some additional health benefits of sex:

Stress relief: The rush of hormones boosts mood, fosters feelings of closeness and helps manage stress for days.

Weight: Sex burns about five calories per minute, meaning it would take roughly 12 hours to lose a pound.

Better Sleep: After exertion, oxytocin and prolactin bring on satiation and sleep—especially in men.

Longevity: More sex means longer lives for men; women live longer when they are sexually satisfied.

Heart health: Sex raises heart rates about as much as climbing two flights of stairs.

So take advantage of the health benefits of sex and the medical benefits of sex.
