According to Wikipedia, hugging has health benefits. It stimulates the increase of oxytocin and reduces blood pressure. I have also heard varying advices about the number of hugs per day that you need; for example here. Is there a number of hugs a day that would be the most healthy? For example, 5 hugs a day, or 15?
My question is different from this question in the following way: my question is about what number of hugs gives the most health benefits, while the other question is about what number of hugs we need to avoid adverse effects.
