Study Notes
- Laughing is a complex behavior that involves muscle contractions in the abdomen, leading to changes in breathing patterns and increased pressure in the chest cavity.
- Laughing can cause pain due to the increased effort on the abdominal muscles and can also affect muscle responses, leading to sensations like weak legs.
- Humans are not the only animals that laugh; studies have shown that mammals and even some birds exhibit laughter-like behaviors during social play.
- Laughter may have evolved as a way to signal friendly and non-aggressive intentions, especially during play and rough interactions among primates.
- Laughter is believed to have expanded functions after humans separated from other primates, being used not only during play but also in speech to convey precise meanings and emotions.
- Hearing laughter can activate key brain areas, prompting smiles or laughter even without the presence of humor, and human laughter is generally louder than play vocalizations in most animals.
- Laughter is not just a social signal but is also beneficial for individuals, releasing neurotransmitters that promote happiness and reduce stress hormones, potentially improving heart health and stress management.
