According to MedicalNewsToday, loss of consciousness during séx is also known as vasovagal syncope, a term that means the fainting that occurs due to the activation of the vagus nerve.
It is not uncommon for women to lose consciousness during séx. While it may seem alarming, it is usually a harmless occurrence caused by a fluctuation in blood pressure.
However, it is essential to understand the possible underlying causes and the steps one can take to prevent it from occurring.
One of the most common reasons for loss of consciousness during séx is hyperventilation.
As people become aroused, their breathing pattern changes, and they tend to breathe faster and more shallowly.
This increase in breathing rate can cause hyperventilation, which subsequently results in a decrease in carbon-dioxide levels in the blood.
The reduced levels of carbon dioxide reduce the dilation of blood vessels, causing a decrease in blood pressure that can lead to fainting.
Another common cause of loss of consciousness during séx is a sudden drop-in blood pressure.
During sexual activity, blood rushes to the genital area, and this can cause a drop in blood pressure, which can result in lightheadedness or fainting.
Moreover, position matters as well. If the woman is lying on her back, the uterus can press against the vena cava, which is the main vein that brings blood from the lower half of the body to the heart.
As the vein becomes compressed, blood flow is restricted, leading to a decrease in blood pressure and, in some cases, fainting.
Additionally, some women may experience postural hypotension, which means that their blood pressure drops upon standing.
This phenomenon can become more severe when engaged in sexual activity and can lead to the loss of consciousness.
According to Healthline, psychological factors can also play a role in causing some women to faint during séx.
For example, women experiencing high levels of anxiety, stress or trauma can lead to a surge in the production of cortisol and adrenaline hormones, which can subsequently cause a sudden drop in blood pressure resulting in fainting.
Some experts also suggest that an órgasm can affect the balance of chemicals in the brain, which may cause a temporary disruption in consciousness.
Additionally, the intensity of the orgasm can cause muscle contractions which can block the flow of blood to the brain, resulting in a loss of consciousness.
The prevention of fainting during séx depends on the underlying cause. If it is related to hyperventilation or sudden drop-in blood pressure, making some adjustments to position, like keeping the legs elevated or avoiding intense thrusting, can help.
Moreover, drinking plenty of fluids and avoiding alcohol and drugs before sexual activity can reduce the likelihood of fainting.
If the cause is related to an underlying medical condition, it is essential to consult a doctor and receive the necessary treatment.
