Babies' cries can make humans physically hotter, study finds.

New study finds babies' distressed cries trigger emotional and physical responses in adults.

Why it matters

  • Shows how humans are biologically wired to respond to infants in distress.
  • Challenges stereotypes about gender differences in responding to babies' cries.

By the numbers

  • The study involved 16 different cries over four sessions.
  • The effect was stronger and more synchronized when babies were more distressed.

The big picture

  • Both men and women respond similarly to babies' cries.
  • Previous assumptions about gender differences in response to baby cries may be incorrect.
  • This response is likely an evolutionary adaptation to ensure babies receive care.

What they're saying

  • Some commenters note personal experiences of being more responsive to baby cries than their partners.
  • Others mention that their response to baby cries changed after having children.
  • A study cited in the comments found that men are as likely as women to wake up to a baby's cry, but mothers are more likely to tend to the child.

Caveats

  • The study was done with volunteers who had little or no experience with babies.
  • It's too early to know if there will be practical applications from this research.

What’s next

  • More research could explore potential applications of these findings.
  • Further studies could look at how experience with babies affects response to their cries.
