According to a study published in the journal “PLOS One,” there is scientific evidence to support the claim that people appear to “glow” after having sex. The study found that individuals who had sex in the past two days had higher levels of oxytocin, a hormone associated with bonding, love, and trust, compared to those who did not have sex. Oxytocin is known to increase blood flow to the skin, which can lead to a rosy glow.
Apart from oxytocin, other hormones such as dopamine, prolactin, and vasopressin, which are released during sex, can contribute to a “glowing” appearance. Dopamine is linked with pleasure and reward, prolactin with milk production in women, and vasopressin with bonding and social attachment. The combination of these hormones can lead to several physical changes, such as increased blood flow to the skin, heart rate, respiration, muscle tension, sweating, and pheromone production, resulting in a flushed, radiant, and healthy appearance.
However, not everyone experiences a “glow” after sex, and the intensity of the effect may vary depending on individual biology and the intensity of the sexual experience. Therefore, it is important to note that the “glow” is not a universal experience. Nevertheless, the scientific evidence suggests that the release of hormones during sex can lead to physical changes that can contribute to a more vibrant appearance.
