Good Chemicals that Massage induces

Serotonin

ser·o·to·nin

ˌsirəˈtōnən,ˌserəˈtōnən/

Serotonin is also key to mood regulation; pain perception; gastrointestinal function, including perception of hunger and satiety; and other physical functions.

Oxytocin

ox·y·to·cin

äksəˈtōs(ə)n/

Oxytocin is the “love hormone”, and it is elevated in nursing mothers and people who fall in love. In general, it promotes the warm and fuzzy feeling. Alas, this effect is limited and fades with time, which may explain why most love affairs eventually cool off. Now here is an intriguing observation. This hormone is released when massage is not vigorous, but rather gentle; the type you get in a spa, getting pampered.
