Here’s the best way to soothe a crying baby, according to science

<p dir="ltr">A crying baby who can’t get to sleep can be a frustrating and frequent occurrence for parents and caregivers - but here’s the best way to go about calming them down, according to science.</p> <p dir="ltr">A team of scientists tested multiple methods for soothing a baby to help them sleep and found a winner: holding and walking with them for five minutes.</p> <p dir="ltr">Kumi Kuroda and her colleagues at the RIKEN Center for Brain Science in Japan have been studying the transport response, an innate reaction seen in animals with young that are immature and can’t look after themselves, including mice, dogs, monkeys and humans.</p> <p dir="ltr">After observing that when animals picked up their young and walked with them, the infants become more docile and their heart rates slow down, Kuroda and her team wanted to compare the effect of this transport response against other motions, such as rocking or holding.</p> <p dir="ltr">The team then compared four methods of soothing 21 infants: being held as their mothers walked, being held by their sitting mother, lying in a still crib, or lying in a rocking cot.</p> <p dir="ltr">They found that when babies were being carried by mothers who were walking, their heart rates slowed within 30 seconds, with a similar effect seen when infants were in rocking cots.</p> <p dir="ltr">Surprisingly, the effect wasn’t seen among babies who were in a still cot or held by mothers who were sitting down, suggesting that holding a baby isn’t enough to soothe them.</p> <p><span id="docs-internal-guid-807deed6-7fff-f6e3-3ebf-d5ab4b532e5f"></span></p> <p dir="ltr">They found that the effect was even more apparent when babies were held and walked with for at least five minutes.</p> <p dir="ltr"><img src="https://oversixtydev.blob.core.windows.net/media/2022/09/baby-crying-method.jpg" alt="" width="1280" height="720" /></p> <p dir="ltr"><em>Kumi Kuroda and her team at the RIKEN Brain Center have proposed a new method for soothing crying infants and helping them fall (and stay) asleep. Image: Current Biology Ohmura et al (Supplied)</em></p> <p dir="ltr">All of the babies in the study stopped crying, with nearly all falling asleep. But, more than a third became alert again within 20 seconds of being put to bed and every baby showed changes in heart rate when they were detached from their mums.</p> <p dir="ltr">Interestingly, the team found that babies that were asleep for a longer period before being laid down were less likely to wake up during the process of being put to bed.</p> <p dir="ltr">Kuroda, herself a mother of four, said she was surprised by the results.</p> <p dir="ltr">“I thought baby awoke during a laydown is related to how they’re put on the bed, such as their posture, or the gentleness of the movement,” Kuroda says. </p> <p dir="ltr">“But our experiment did not support these general assumptions.” </p> <p dir="ltr">As a result of their study, the team has proposed a method of soothing a baby to help promote sleep and stop them from crying.</p> <p dir="ltr">After holding and walking your crying infant for five minutes, the team recommends sitting and holding them for another five to eight minutes before putting them to bed.</p> <p dir="ltr">Though it goes against common approaches such as waiting for a baby to cry until they fall asleep by themselves, the team’s new method aims to be an immediate solution for a crying infant.</p> <p dir="ltr">The team also note that their new method would also need to be investigated further to determine whether it had any long-term improvements for infants and their sleep.</p> <p dir="ltr">“Many parents suffer from babies’ nighttime crying,” Kuroda adds. </p> <p dir="ltr">“That’s such a big issue, especially for inexperienced parents, that can lead to parental stress and even to infant maltreatment in a small number of cases.</p> <p dir="ltr">“For many, we intuitively parent and listen to other people’s advice on parenting without testing the methods with rigorous science. But we need science to understand a baby’s behaviours, because they’re much more complex and diverse than we thought.”</p> <p dir="ltr"><span id="docs-internal-guid-2d9f374c-7fff-1719-f199-7b68bff57193"></span></p> <p dir="ltr">Their findings were publishing in the journal <em><a href="https://doi.org/10.1016/j.cub.2022.08.041" target="_blank" rel="noopener">Current Biology</a></em>.</p> <p dir="ltr"><em>Image: Getty Images</em></p>

Dogs cry ‘happy tears’ when reunited with their favourite humans

<p dir="ltr">Along with frenzied tail-wagging and plenty of face licks, new research suggests that dogs can even shed tears when they’re happy to see you.</p> <p dir="ltr">Takefumi Kikusui, a researcher in the school of veterinary medicine at Japan’s Azabu University, first observed the phenomenon six years ago while watching his poodle nurse her puppies, when he noticed there were tears in her eyes.</p> <p dir="ltr">“That gave me the idea that oxytocin might increase tears,” he said.</p> <p dir="ltr">Oxytocin is known as the maternal or “love hormone”, Kikusui explained, with previous research finding that the hormone is released in both dogs and their owners when they interact.</p> <p dir="ltr">To test their teary theory, Kikusui and his colleagues decided to run an experiment where they reunited dogs with their familiar humans, as well as with strangers, and measured the volume of tears in the dogs’ eyes before and after.</p> <p dir="ltr">Publishing their findings in the journal <em><a href="https://doi.org/10.1016/j.cub.2022.07.031" target="_blank" rel="noopener">Current Biology</a></em>, the scientists found that tear volume increased when the pooches returned to their favourite humans, but not with a person they didn’t know.</p> <p dir="ltr">In a second experiment, the team added oxytocin to the dogs’ eyes to see whether there was a connection to the tears. With the tear volume also going up after oxytocin was added, they concluded that it was proof that oxytocin plays a role in tear production when dogs interact with their owners.</p> <p dir="ltr">Surprisingly, when they asked people to rate dog faces with and without tears, people gave more positive responses to photos of teary-eyed pups, suggesting that tear production in dogs also helps them and their owners forge stronger connections.</p> <p dir="ltr">“We had never heard of the discovery that animals shed tears in joyful situations, such as reuniting with their owners, and we were all excited that this would be a world first!” Kikusui said.</p> <p dir="ltr">Having found that dogs produce tears in situations we’d consider ‘happy’, future work will look to see how teary they get in response to negative emotions and whether being teary plays a social role in how dogs interact with each other.</p> <p dir="ltr">“Dogs have become a partner of humans, and we can form bonds,” Kikusui said. </p> <p dir="ltr">“In this process, it is possible that the dogs that show teary eyes during interaction with the owner would be cared for by the owner more.”</p> <p><span id="docs-internal-guid-2be14e3c-7fff-ae30-980c-cb1393604fd2"></span></p> <p dir="ltr"><em>Image: Getty Images</em></p>

Why do we cry?

<p>As you know, crying is something everyone does sometimes. Sometimes we get teary because our bodies are trying to clean a bit of dirt out of our eyes. But that’s not really crying, is it? Crying has something to do with our emotions.</p> <p>There’s a connection between the part of our brain that feels emotions, and the ducts in our eyes where tears come out - so when we have a big feeling, <a href="https://www.ncbi.nlm.nih.gov/pubmed/17363076">we cry</a>.</p> <p>Doctors of medicine could tell you more about that. But I’m a doctor of another subject – the history of emotions. I learn about why people cry for different reasons, and it’s my job to compare today with a long time ago.</p> <p>In Australia today, most kids cry when they’re feeling sad, whether they’re boys or girls. But once those kids become teenagers, boys <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/per.386">seem to cry less</a> often than girls do. This isn’t because boys have different brains or tear ducts than girls. It’s mostly because many Australian boys think crying is a bit embarrassing.</p> <p>Maybe they’ve been told boys don’t cry, or <a href="https://journals.sagepub.com/doi/10.1080/01650250143000058">teased by their friends</a> if they cry at school.</p> <p>In fact, it is very normal for boys to cry. And crying hasn’t always been seen as embarrassing or uncool.</p> <p><strong>The history of crying</strong></p> <p>About 500 years ago in England, crying was seen as really cool! One of the most famous stories at the time was about <a href="http://www.gutenberg.org/ebooks/1251">King Arthur</a>.</p> <p>He was a great hero, and a lot of boys wanted to be like him. According to books and poems written at the time, <a href="https://www.historyextra.com/period/medieval/heavenly-dew-crying-in-the-middle-ages/">King Arthur cried a <em>lot</em>.</a> Crying showed everybody he had very strong, true feelings. Back then, people thought this made him a great man, and the lords and ladies in his court cried in public too.</p> <p><strong>Crying around the world</strong></p> <p>Why we cry can also depend on <a href="https://journals.sagepub.com/doi/abs/10.1177/1069397111404519">where we live</a>, and what our family is like.</p> <p>If you live in a country where it’s normal to express a lot of feelings in public, such as America, you are more likely to cry about things.</p> <p>If you live in a country where people don’t usually make a big show of how they feel, you probably won’t cry as much, even if you’re feeling sad on the inside.</p> <p>For example, in Japan, for a long time people tried not to cry. But lately in Japan, people are <a href="https://www.oxfordscholarship.com/view/10.1093/acprof:oso/9780198570240.001.0001/acprof-9780198570240">changing their minds</a> about crying. Books and movies that are very sad are becoming popular. There are even <a href="https://www.theatlantic.com/magazine/archive/2015/05/crying-it-out-in-japan/389528/">crying clubs</a>, where you can watch a sad movie with other people, have a good cry, and go home feeling better because you let out a lot of big feelings!</p> <p>The same goes for <a href="https://www.oxfordscholarship.com/view/10.1093/acprof:oso/9780198570240.001.0001/acprof-9780198570240">families</a>: if everyone at your house likes to share how they’re feeling, and isn’t embarrassed about crying or laughing or shouting or dancing, then you’ll probably cry whenever you feel like it.</p> <p>But if the people in your family don’t usually show how they feel, then you will also learn to keep your feelings inside and not let them show by crying.</p> <p><strong>We cry to show our feelings</strong></p> <p>As you can see in these examples, crying isn’t just something we do by ourselves. Quite often, crying is a way for us to show other people how we feel.</p> <p>When you cry, your parents, teachers or friends know that you’re having a big feeling. Then they can help you feel better with a hug, or a talk about your feelings.</p> <p>So why do we cry?</p> <p>Well, partly because our bodies are made that way. But also because crying is how people around us show their feelings, and we learn to show our feelings the same way. Crying helps us share and care.</p> <p>And I think that’s a wonderful thing.</p> <p><em>Written by Carly Osborn.
