There is such a thing as a perfect cuddle.
The trick is, not to squeeze too tight. Researchers from Japan’s Toho University figured it out by measuring the calming effect on infants of hugs of different pressures, and when given by strangers compared to from parents.
Babies liked the medium hug. It’s not just being held or squeezed tightly… it’s just right. As far as how long the cuddle should last, they figure 20 seconds. For the full effect to be met, a parent and no one else can hug the child.
There’s a bonus here for parents. They also experienced the calming effect the hug had. The research will continue to study hugs and will tie in to autism studies.
