A simple phone call from mom can calm frayed nerves by sparking the release of a powerful stress-quelling hormone, according to researchers at the University of Wisconsin-Madison, US.
Once stressed, one-third of the girls were comforted in person by their mothers — specifically with hugs, an arm around the shoulders and the like. One-third were left watch an emotion-neutral 75-minute video. The rest were handed a telephone. It was mom on the line, and the effect was dramatic.
