(CNN)-- Want to strengthen your relationship with your partner?

Lebanese health and wellness coach Nadine Khalil, who runs the "wellnessbynadine" account on Instagram, recommends trying the 6-second kiss. (Watch the video above.)

During this brief period, the brain has enough time to send a signal to the body to release happiness hormones, such as:

oxytocin,

dopamine,

and serotonin.

In her conversation with CNN Arabic, Khalil explained that these hormones help with the following:

improving mood,

increasing feelings of comfort and vitality,

and enhancing emotional bonding between partners.
