This article is brought to you by Dr. Saeed Behckam, clinical psychologist, counselor, and sex therapist serving clients in Iran (Tehran) and Canada (Toronto, Richmond Hill, and Vancouver).
The Gottman’s 6-Second Secret
John and Julie Gottman — world-renowned psychologists and founders of The Gottman Institute — discovered a “golden number” after studying over 3,000 couples for more than three decades:
A 6-second conscious kiss is enough to trigger the release of oxytocin, the so-called “love hormone.”
Oxytocin calms the fear center in the brain, increasing trust, empathy, and emotional safety between partners.
The Magic of a 20-Second Hug
According to American neuroscientist Paul Zak, hugging for 20 seconds produces similar effects.
This prolonged contact helps the nervous system relax and lowers levels of stress hormones such as cortisol.
How to Start the Practice
The Gottmans recommend couples dedicate a small moment each day to this intimacy ritual — for example:
-
Before leaving for work
-
Or right before bedtime
