Touch stimulates oxytocin, often called the bonding hormone. Oxytocin promotes feelings of trust and connection, while also helping regulate the body’s stress response.

Research indicates that affectionate touch can lower cortisol, the stress hormone levels. When cortisol drops, the body shifts from “fight or flight” into a calmer, more regulated state.

Physical connection promotes serotonin release, a precursor to melatonin. This chemical transition helps stabilize the body’s circadian rhythm, facilitating a quicker transition to deep, restorative sleep.
