You may enjoy sex, but have you ever taken the time to consider the science behind it all? Your body undergoes certain changes when it participates in intercourse. While the effects may vary to a certain degree from person to person, the basic response is the same.

So how does sex affect your physical being? Let us find out.

The release of happy hormones:

Along with adrenaline, hormones like dopamine and oxytocin are released into your blood which make you feel happy collectively. The oxytocin helps you feel connected to your partner and makes the experience intimate. The dopamine, on the other hand, activates the reward system of your brain. You feel motivated, excited and satisfied. As a result, you develop a close connection with your partner after sex that feels akin to love.

Widening blood vessels:

The dilated blood vessels cause you to flush and turn a shade redder. The blood vessels in your vaginal wall undergo more dilation than the rest of your body. That is the reason your vulva and clitoris are engorged- this facilitates better lubrication, and so the sex is smoother. The excess secretion makes the experience more pleasurable.

Increased sensitivity:

There are certain erogenous zones which are more affected by during sexual intercourse than the other parts of your body. These include tips, ears, genital area, breasts and the neck. During sex, they become very sensitive due to the enhanced blood flow. The secretion of sensation-enhancing neurotransmitters make them more receptive to touch.

Building up of bacterial elements:

Bacteria from the vaginal area or the anus can get transported to the urethra during sexual intercourse. These bacteria can then procreate and multiply, which could lead to a severe urinary tract infection. This is why hygiene is so important. Wash your hand and pee before and after sex without fail. Use a sanitizer than can kill any remaining bacteria.

Burning of calories:

Sex is, in fact, very good exercise for your body. A certain study in The New England Journal of Medicine concluded that a person weighing 154 pounds would lose 21 calories of six minutes of sexual activity. How cool is that? The way to fitness has never been pleasanter.

A Racing Heart:

Your heartbeat increases when you are engaged in sexual activity. It hits the peak when you orgasm, and slowly settles down after some time. You can also attribute this to the adrenaline rush.

Tense Muscles:

The pelvic floor muscles contract involuntarily during sex. This movement can help increase arousal and consequentially, pleasure.


Orgasms cause an increased secretion of prolactin which helps in calming you down. This can be a good stress-buster too. What better way to forget about your difficult day at work?

If you practice healthy sex, there can be nothing like it. It is better to be well-informed about all aspects of sexual activity and its effect on your body to be on the safe side.
