Here is the technical answer to how good hugging feels...
Some of the neurochemicals include the hormone oxytocin, which plays an important role in social bonding, slows down heart rate and reduces stress and anxiety levels.
The release of endorphins in the brain's reward pathways supports the immediate feelings of pleasure and well-being derived from a hug or caress.

Hugging is very important interaction for social animals such as humans. When you form a bond with someone, and I include our dolls in that statement, hugging them brings comfort to your inner being. Most modern dolls are as soft as human beings, and they smell lovely too, especially if you use your favourite scent on them.
Also, a doll can and will be hugged for as long as you want to. You could spend an hour hugging her if you want. You can hug every time you pass. You can squeeze as hard as you dare, she won't break or become uncomfortable before you do.
So if you live alone, with a doll your not really alone. There's always that hug to lift your mood and dispel all that stress whenever you need it, willingly given any time of day or night.
Have a good hug on us.
