Christmas is the gift giving holiday. Even people that don’t believe in Christmas give gifts, and they seem to enjoy doing so.
One reason is because of a chemical in our brain called Oxytocin. Oxytocin is a chemical that gives us feelings of wellbeing, but only when we do something for other people. Researchers first thought the chemical was only produced by women shortly after pregnancy to help the bonding between mother and child, but they have recently discovered that this chemical is released whenever someone does something for another person. So keep giving gifts and enjoy that natural high.
