Parents hug their children as an expression of affection, comfort, and joy…and because we like to hug them. Even as adults we recognize a hug as a communication of love, comfort, or celebration. But did you know that hugs have a physical impact on the hugger and the one hugged. A study published in 2020 in iScience confirmed this by monitoring the heart rate of infants under the age of 1-year-old while they were given a 20-second hug, held for 20 seconds, tightly hugged for 20 seconds, or in their crib for 20 seconds. The hug, holding, or tight hug was given by their parent and by a female they did not know (who had experience in childbirth and childcare). Some of their findings you might expect. For instance,
- Children four-months-old and older exhibited a slower heart rate when hugged by a parent. They physically relaxed when hugged by their parent.
- They did not exhibit a slower heart rate or physically relax when hugged by a stranger, even though the “stranger” in this experiment had experience in childbirth and parenting. Experience with children and infants does not replace the hug of a parent!
Some results were a little more unexpected. For instance,
- The parents’ heart rate also slowed when they hugged their children. Parent and child both physically relax when a parent hugs their child.
- The children did not exhibit a slower heart rate or physically relax when simply held or hugged tightly, even if it was their parent. This suggests that a child can differentiate a hug from simply being held and from being held “tightly” (perhaps as a parent holds the child to protect them or while experiencing their own fear or negative emotion.) It is not just physical contact that impacts heart rate and relaxation but an affectionate, loving hug.
This study reveals the heartbeat of a hug for infants and parents. But I wonder if this ever changes in life. Who doesn’t relax into the arms of a spouse’s hug? Who doesn’t rejoice in the hug of their teen? And, if truth be told, what teen doesn’t really enjoy the occasional affectionate hug of a parent? The heartbeat of a hug is more than just a slowing of the heart and physical relaxation. The heartbeat of a hug is a life-giving, joyous celebration of connection. Today, share a few hugs with those you love and experience the heartbeat of a hug!
