Your heart function well
Research says people who have sex once a month or less get heart disease more often than those who have it twice a week or so. Part of the reason could be that you get a bit more exercise and are less likely to be anxious or depressed.
Enhance a good memory
Regular sex has been linked to improved memory, especially if you’re between ages 50 and 89. The reason behind it has not been fully cleared in literature.
Sex boost your immune system
Weekly sex seems to boost your immune system compared to those who have it less often. Part of the reason may be that it raises levels of a germ-fighting substance called immunoglobulin A, or IgA.
Reduce the risk of prostrate cancer
The reasons aren’t exactly clear, but in at least one study, men who ejaculated less than seven times a month were more likely to get prostate cancer compared to those who did it at least 21 times a month.
Promote sound sleep in women
Without sex, you’ll miss out on the hormones that promote restful sleep, like prolactin and oxytocin. Women get an estrogen boost that helps even more.
