Touch primes the brain to release oxytocin. In Zak’s experiment, half the participants received a 15-minute massage and then played an economic game in which they exchanged real money. After being trusted by a stranger with money in the hope that they’d reciprocate, the brains of participants who got a massage released much more oxytocin than those who simply rested alone. Amazingly, those who received massages returned 243 percent more money to the stranger who showed them trust than those who rested.
