Researchers have investigated whether the body is truly disconnected from the external world during sleep. To do so, they focused on how heartbeat changes when we hear different words during sleep. They found that relaxing words slowed down cardiac activity as a reflection of deeper sleep and in comparison to neutral words that did not have such a slowing effect. This discovery sheds new light on brain-heart interactions during sleep.
