Concern for mental health is growing in an era dominated by screens and haste, where physical contact becomes an essential language for well-being. Psychology insists on the need for this proximity for emotional regulation, as the body speaks a language much older than notifications.
“"If we want a hug to have real effects on mental health, it must last at least 20 seconds. And that would be the minimum."
This minimum duration of 20 seconds is justified by the activation of three biological mechanisms. The first affects the parasympathetic nervous system, which takes the body out of alert mode and calms it down.
The second mechanism is hormonal, as a long hug increases the production of oxytocin, known as “the hormone of proximity and trust.” Finally, the third effect acts on cortisol, the stress hormone, helping to release accumulated tension and provide comfort after a bad day.
