Touch has existed since the dawn of time and is far more profound to the well being of human existence. Touch is our primary language of compassion, and a primary means for spreading compassion.
“To touch is to give life”
Regrettably, though, some Western cultures are pretty touch-deprived, and this is especially true of the United States.
Ethologists who live in different parts of the world quickly recognize this. Nonhuman primates spend about 10 to 20 percent of their waking day grooming each other. If you go to various other countries, people spend a lot of time in direct physical contact with one another—much more than we do.
Of course, there are plenty of good reasons why people are inclined to keep their hands to themselves, especially in a society as litigious as ours. But other research has revealed what we lose when we hold back too much.
The benefits start from the moment we’re born. Touch activates the brain’s orbitofrontal cortex, which is linked to feelings of reward and compassion. Touch also builds up cooperative relationships—it reinforces reciprocity between our primate relatives, who use grooming to build up cooperative alliances.
There are studies showing that touch signals safety and trust, it soothes. Basic warm touch calms cardiovascular stress. It activates the body’s vagus nerve, which is intimately involved with our compassionate response, and a simple touch can trigger release of oxytocin, aka “the love hormone.” Touch can even have economic effects, promoting trust and generosity.
“Touch therapy” or “massage therapy” may sound like some weird Berkeley idea, but it’s got hard science on its side. It’s not just good for our muscles; it’s good for our entire physical and mental health.
Proper uses of touch truly have the potential to transform the practice of medicine—and they’re cost effective.
But to me, the science of touch convincingly suggests that we’re wired to—we need to—connect with other people on a basic physical level. To deny that is to deprive ourselves of some of life’s greatest joys and deepest comforts.
