Research has begun to characterize the physiological and psychological mechanisms behind post-interaction fatigue. A 2026 study in the Annual Review of Neuroscience describes “social hangover” or social saturation as a state of mental and physical exhaustion following intense socialization, suggesting the brain functions like a “social thermostat” to maintain equilibrium between interaction and withdrawal.

Complementary research into “emotional hangovers” describes the lingering fatigue, anxiety, and brain fog that follow intense emotional events. This phenomenon is linked to surges in stress hormones such as cortisol and adrenaline. Experts note that the brain’s heightened state of arousal during these events can lead to increased memory vividness and prolonged alertness.
