The chemistry of intimacy

A bumper sticker from the hippy era in the Sixties read: “Candy is dandy, but sex don’t rot your teeth!”  

Apart from the “feel good” emotional benefits, are there are any other physiological benefits for your body?


Hugging increases levels of oxytocin, the so called “love hormone”, which may benefit your heart health. Regularly hugging a loved one can result in lower blood pressure and a healthier heart rate. It also helps to reduce levels of cortisol, the chronic stress hormone, in the body


Kissing prompts your brain to release feel-good chemicals such as serotonin, dopamine and oxytocin. Regular kissing with your partner can significantly reduce stress levels.


A healthy sex life has many beneficial effects on the body, such as:

  • Higher levels of immunoglobulin A, which boosts the immune system.
  • Less likely to develop heart disease.
  • Intercourse has been linked to lower blood pressure and improved stress response.
  • It is excellent exercise that burns 3 – 4 calories per minute.
  • Sexual activity releases pain-reducing hormones.
  • There are indications that men who ejaculate regularly may have a lower risk of prostate cancer.
  • The hormones prolactin and oxytocin that are released during and after sex helps to improve sleep.
  • Regular sex improves the libido.
  • Increased levels of the “love hormone” oxytocin increases feelings of intimacy and bonding to your partner.
