Wednesday, Sept. 14, 2022 (HealthDay News) — A new study offers parents a seemingly magical gift: a simple, free technology that puts crying babies to sleep in just 13 minutes.
Researchers in Japan found that walking around with the baby for five minutes calmed the newborn, and after sitting quietly with the sleeping baby for eight minutes, the transfer to the crib was smooth.
The team studied the calming process using a method baby An electrocardiograph and video camera compared changes in heart rate and behavior in 21 mothers while performing some common baby-soothing activities. These include holding babies, pushing them into strollers, and holding them while sitting.
The researchers were able to record detailed data on babies who were crying, awake, and calm or sleeping. The idea is to track changes in behavior and physiology very precisely.
The team found that “walking for 5 minutes promoted sleep, but only in crying infants. Surprisingly, this effect was not present when the infant was already calm beforehand,” said study author from RIKEN, Saitama Prefecture. said Dr. Kumi Kuroda of the Institute’s Brain Science Center. Japan.
Regardless, all the babies in the study stopped crying by the end of the five-minute walk and had lower heart rates. About half of them fell asleep.
The study found that babies are very sensitive to all the movements of their mothers, and their heart rate changes when the mother stops walking or just turns around. The most significant events that plagued sleeping babies occurred when they were separated from their mothers, demonstrating the problem of waking sleeping babies when they were put down.
“Although we didn’t predict it, a key parameter for successfully laying a sleeping baby down is the latency after falling asleep,” Kuroda said in a RIKEN press release.
Specifically, babies typically woke up if they were put down before they fell asleep for about eight minutes.
To address this, Kuroda suggested that mothers should hold a crying baby steadily for about five minutes with few abrupt movements, then sit for about eight minutes before letting them lie down to sleep.
The study doesn’t address why some babies cry so much that they can’t sleep, but it does offer a solution that could help parents.
In addition, “We are developing a ‘baby tech’ wearable device through which parents can view their babies’ physiological status in real time on their smartphones,” Kuroda said. “Like science-based fitness training, we can use these advances for science-based parenting and hopefully help babies sleep and reduce parental stress caused by babies crying excessively.”
The findings were published Sept. 13 in Current Biology.
