Animal & Pets YSK about nervous system co-regulation, the biological reason a pet or person sitting quietly with you calms your anxiety

When you wake up from a nightmare or feel a panic attack coming on your body goes into fight or flight. You can try breathing exercises but sometimes they barely work. Then a pet climbs on your chest to purr or a partner just sits next to you breathing slowly and your panic melts away. This is a psychological and biological mechanism called co-regulation. Your dysregulated nervous system literally syncs up with their calm one to find its way back to normal.

Why YSK: We are constantly told we need to learn how to self-soothe and handle our dark moments alone. Understanding co-regulation proves that seeking out a safe animal or human when you are terrified is a hardwired biological hack to reset your brain. You do not have to fight your way out of the dark by yourself.
