Sexual intercourse is known to impact the way in which the rest of our body functions.
Recent studies have shown that it can have an effect on how much we eat, and how well the heart functions.
Reported on Medical News Today, sex has been cited as an effective method of burning calories, with scientists noting that appetite is reduced in the aftermath.
Also, a study published in the Journal of Health and Social Behavior in 2016 found that women who have satisfying sex later in life might be better protected against the risk of high blood pressure.
Many of the effects of sex on the body are actually tied to the way in which this pastime influences brain activity and the release of hormones in the central nervous system.
Here, we explain what happens in the brain when we are sexually stimulated, and we look at how this activity can lead to changes in mood, metabolism, and the perception of pain.
Brain activity and sexual stimulation
For both men and women, sexual stimulation and satisfaction have been demonstrated to increase the activity of brain networks related to pain and emotional states, as well as to the reward system.
This led some researchers to liken sex to other stimulants from which we expect an instant “high,” such as drugs and alcohol.
The brain and penile stimulation
A 2005 study by researchers at the University Medical Center Groningen in the Netherlands used positron emission tomography scans to monitor the cerebral blood flow of male participants while their genitals were being stimulated by their female partners.
The scans demonstrated that stimulating the erect penis increased blood flow in the posterior insula and the secondary somatosensory cortex in the right hemisphere of the brain, while decreasing it in the right amygdala.
The insula is a part of the brain that has been tied to processing emotions, as well as to sensations of pain and warmth. Similarly, the secondary somatosensory cortex is thought to play an important role in encoding sensations of pain.
