Science links sleep habits to emotional wiring.

Sharing a bed with a pet often starts as a small exception and quietly becomes routine. Over time, that choice reflects how someone handles closeness, stress, and comfort when defenses are lowest. Sleep is one of the most neurologically vulnerable states humans enter each day. Who we allow into that space reveals patterns in attachment, regulation, and empathy that show up elsewhere in life. Research in psychology and neuroscience suggests that people who sleep beside their pets tend to cluster around specific emotional and behavioral traits shaped by both biology and experience.
