EInsufficient14255 studies referenced
Latest evidence update: 2026-04-15
Physical touch triggers oxytocin release, reduces cortisol, and activates the vagus nerve. Regular hugging (at least 4 per day) is associated with lower blood pressure, reduced infection susceptibility, and buffered stress responses. C-tactile afferent fibers respond specifically to gentle, social touch.
How to do it
1Hug loved ones for at least 20 seconds (threshold for oxytocin release)
2Aim for 4+ meaningful physical touch interactions per day
3Include handholding, back rubs, or gentle shoulder touches
4If touch-deprived, consider massage therapy or partner dancing
Safety notes
Always ensure touch is consensual. Respect personal boundaries and cultural differences around physical contact.
