Welcome to PC!
I hope you will find the information and the support you may be seeking.
Hugs are great!
Once read a study about puppies done at a hospital. For a couple of days, the staff had ignored the puppies, only giving them their food. Bloodwork in the puppies showed a depressed immune system.
Next, the staff interacted with the pups, petting them, touching them, interacting with them for a couple of days. LANs were repeated. After much touching, the ups had stronger immune systems!
This is not about hugs specifically; yet it is about touch, which occurs with hugs!
I wish I knew how/where to find the study!
So glad you have joined in with us!
