1It’s Not Just Cute, It’s Chemical
Sleeping with a pet isn't just "cozy." It triggers a potent chemical exchange. Touching your dog releases Oxytocin (the love hormone) which actively combatsCortisol (the stress hormone). It acts as a living, breathing anxiety blanket.

Research suggests a correlation between pet interaction and cardiovascular health. It's not a cardio workout, but it's a nightly heal session.

Sleep is vulnerable. Evolutionarily, we stay alert. By "outsourcing" vigilance to a pet (who hears and smells better), your brain can finally drop its guard.

Your brain is scanning for danger.

"The comfort a dog provides creates a cozier environment for you both... helping to diminish experiences and make sleep less traumatic."
For those with trauma, a pet is a therapeutic necessity. They provide an immediate "grounding" force. The tactile sensation of fur and weight bridges the gap between a nightmare and reality, allowing the sleeper to orient themselves in the "now" faster than medication alone.
